Moonraker Micro CB radio

My recent main YouTube video was on the Moonraker Micro CB radio, which is indeed a compact radio, based on an AnyTone chassis as it turned out so has the 10-meter mode and the naughtiness inside, though of course I have no issue putting this set on 10 it does not have SSB capability and being channelised may require a frequency counter to get an idea what channel is associated with which frequency if you want to use it on 10.

The radio came to me with bare ended wires so I fitted a cigarette lighter plug, rated 5A as this is ample for this radio, to be able to plug it in in the car to do tests, the radio seems to do well, and is good when put against a comparable set, which in my case was a PNI Escort HP7120.

When I did the original bench tests on the radio the power levels were reading lower than expected, however later testing showed it was in fact fine.

Both videos are below

both antennas arrived, both scheduled for YouTube upload by Monday

I now have both antennas that I ordered, however the Thunderpole Boomerang antenna was to be delivered by Parcelforce (or Parcelfarce as I call them because they are incredibly useless) and they failed to deliver it to a neighbour as instructed, ignored the fact I rescheduled and left it at Catterick Garrison Post Office meaning after filming the video for the Sirio Hi-Power 4000 (and subjecting it to 70MPH due to a trip to nearby Darlington to do a bank run) I had to call at the Post Office to collect it, with that done editing work was finished for the Sirio antenna and the Boomerang unboxing video was filmed.

A big surprise with the Sirio was that I did not need to adjust it, SWR under 1.5:1 across all 80 channels, for the most part, the top end of 27/81 was about 1.4 which is acceptable, I was to compare between my K-Po and Zetagi SWR meters however this did not happen because another vehicle parked next to my car before I could do that, and the driver did not seem happy that I was even up there, probably because I don't own a dog, unfortunately public land means I have a right to go up there, it is ideal for radio given height and forms part of my mobile standardised test route, now I have the antenna I will be doing a dry run on video before actually doing anything on the air to show you the route from the car.

The only part to do from the perspective of the new antennas is the on-air test of the Boomerang, once it is up and tuned, given the fine adjustments that may be needed I won't bore you and give a final SWR reading as per the K-Po meter, the Zetagi meter, and the one built in to the President Grant II.

I will be working from 4pm tonight and as ever will be monitoring UK 19, which is usually full of the burner brigade running illegal power to speak to their pals which the 4 watts can do fine for them but they generally don't have a good understanding of this fact, that and they have the squelch turned all the way up which is a bit ridiculous really, maybe even with them I may notice a difference on this antenna on receive, the one thing that will be noticed is the fact I have a bigger antenna on the car.

Thunderpole T-3000 is winging its way to my shack

Today was my payday, and factoring in that I have a bit of extra cash left over from my salary I placed an order for a Thunderpole T-3000 CB radio, which so far I have heard good reports about, this radio has already been looked at by RustySkull Productions on YouTube and Lewis M3HHY from channel "RingwayManchester" has looked at the radio this is a rebadge of, the Nanfone CB-689, and tested with another station radio to radio, the other station having the T-3000, was found to work well.

I plan to use this radio as my main mobile CB, even though it does not have SSB which I only really use parked up because adjusting the RIT (or clarifier as it's called on CBs) while mobile is a pain and with SSB you sometimes have to concentrate on the incoming audio which is certainly not ideal while driving, as this radio is so slimline it can fit any modern car with ease either into a DIN sized space or fixed to the dash with a bracket in the normal way.

The unit I ordered is an ex display unit, what that means is that Thunderpole have had it out of the box and had it on display, though they will have tested all accessories to ensure they function, particularly the microphone, which although has an LED in it, or at least a position for one, no LED lights up on transmit, this is because an optional Bluetooth mic is available for the Nanfone unit and would work with this as well, by virtue of the Kenwood HT type connector on the front (as I have a speaker mic and some headsets from Baofeng radios that fit I may test these too.

Naturally I will be doing a video with this radio, power tests (4 watts of course), how it looks and feels, ease of use and hopefully if there are any stations on that day a radio report.

I plan to mount this radio in the car, and ultimately keep my Grant II for portable work on 11-meters SSB, the antenna on the car at the moment for 11-meters is in fact my Orbitor/Tornado Stinger antenna that during the summer my XYL painted white and her and I converted into the antenna we dubbed the 'spider antenna', the magmount is an older version of the Sirio magmount I have in use for my 2/70 antenna, except this older one had near destroyed cable so I had to rewire it using coax from a snail mount I was not using, I will later on be replacing the rear antenna with something similar to the antenna I loaned, I'll have to see if GB Communications sell one of these because I then don't have to travel far and can swap the antennas over immediately, provided I remember an SWR meter because the T-3000 does not have one installed.

I certainly am eager to receive one of the most unique CB radios made today to fit into the most unique Toyota Aygo of them all, not because I've fitted radio equipment in it but because it did a journey from my home QTH to well into Bavaria and back and did not seem bothered, so a unique design of CB radio should complement it nicely.

There is a Sci-Fi connection with the naming scheme of the Thunderpole T-series CB radios, I've spotted it, can you spot it too?

I have started monitoring and calling out on 19 due to the appearance of a Ford Fiesta, a Volkswagen Bora and a pick up truck all equipped with Orbitor style antennas, so I know people are out there using the CB, and I'm pretty sure the drivers of these vehicles have seen the antennas on my car too, and I saw a video on YouTube where a CB operator drives to work on the motorway, gets passed by an HGV and the driver of the HGV calls out after seeing the antenna on the car of the operator that's filming, I suspect he's using a President Grant II in that video, no idea what the trucker was using though.

Hope to catch you on the CB and also don't forget as I'm a licenced Amateur radio operator I can be found on local repeaters in my area and sometimes the calling channel on 2-meters.

Team RoadCom-FS-UK hopefully coming to my shack real soon

Been scouring eBay at CB sets recently seeing if I could find a bargain or two, no Audioline 341s sadly as I am still after one of these to this day, however another radio I've been after for a while did show up, the Team RoadCom-FS, the UK variant of this radio, it fits a car stereo spaced hole (DIN mount) though can be mounted on a standard rig bracket, the radio I found was advertised with a K-PO linear amplifier, which I'd never use on CB other than into a dummy load, an SWR meter with power measurement, useful to have, a magmount that appeared to be a Sirio Mag 145 PL, a through body mount, and what appeared to be an antenna switch, so some testing to do, winning bid of £49! Yes it really was £49, add in shipping it comes to £57, so a bargain even for just the radio that retailed, when new, for £100+ (£135 as listed on Radioworld.co.uk, though of course they report it out of stock as it was new in 2008, making the radio at most 11 years old, my oldest CB is 13 years old this year).

The radio is one of the few that have CTCSS on board that are type approved for the 11-meter band, the original RoadCom,the TTI TCB-1100 and at least one or two Albrecht radios have this as well but it is very rare to find it on a CB radio, "export" radios (those meant for 10-meters) have it due to the fact that 10-meters is an Amateur band and occasionally you will find repeaters there that would require CTCSS to access them, there are no repeaters on 11-meters but FRN gateways do sometimes operate there with CTCSS on board, though this is rare (the gateway in Clacton-on-Sea, for instance, is open on UK29).

The radio started a trend of DIN size radios with front speakers, the Albrecht AE6491 and its rebadged cousins being an example of this, the TTI TCB-1100 is also similar in this regard, both these radios are still available new however.

Naturally on arrival I will inspect the radio and anything that comes with it and test as appropriate, RF generators into dummy loads, cables for continuity, mic audio on the radio's TX during tests, my Maplin linear supply would happily run the radio, however current draw from the linear may require me to use a slightly higher current rated supply, I have an old ATX supply under the desk I was using to power the SS9900 with.

I'll update on this when the items arrive

New telescopic mast ordered in time for The Big Multimode net and also for portable Amateur HF ops

I have ordered a new mast from SOTAbeams today, this one is a 7m mast as opposed to a 10m mast though this is not any real issue, with there being just under two weeks before the Big Multimode Net I needed to remedy the mast situation.

Though the news I posted yesterday is still fresh in my mind I understand that the hobby must go on and though the net on the 27th is for 11-meters (CB radio) it is still radio none the less, and I will operate that day as 26CT730/P from, I hope, Tan Hill, and hopefully achieve something I've wanted to do for many years, work Roy in Corsica if he is listening and the conditions are good on the day.

The radio I hope to use is my President Grant II, it has had very little airtime since I bought it, and it's legal for 11-meter SSB use.

Of course the mast I've bought will be grand for portable HF ops when I have some portable HF gear (I've been looking at Yaesu FT-817s as these are becoming available a little cheaper due to the 818 but still outside my price range), I will still, however, use type approved CB equipment for 11-meters even in portable ops so anything for Amateur HF will be for exactly that, I believe that the SOTABeams masts are good for long wires, though I suspect two spaced appropriately can support a full sized G5RV when I finally do get the portable HF on Amateur radio off the ground.

The Big Multimode Net is a good way to get interest in the radio hobby, no licence and no special equipment, just a normal AM/FM CB radio and an antenna is all you need to get started, you can power a radio easily off the car cigar lighter socket if it's a normal CB.

There is a second "Activate all Counties" event on the same day as the Big Multimode Net at the same time to get all of the English Counties on the air, if you have a CB setup I urge you take part in this, also if you want to do more than what a set of 80 channels on 27MHz and 16 channels on 446MHz allows you to do then go get your foundation licence, it is worth it.

If you're a CB/11-meter operator I look forward to working you on the air on the 27th June

The trusted T2LT antenna for 11-meters, how does it perform over a commercial antenna?

Well to find this out YouTube user "Amateur and 11m radio Tim" (sorry Tim I don't know your callsigns yet) rigged up a commercial antenna, a Sirio 4000, and a T2LT, needless to say those results were impressive.

I have built the T2LT myself as you know, and I know it works as I have got out on it and it pulls in a lot of stations though last time I had it out the conditions left a lot to be desired, however for 11-meters it is the most practical antenna you can get, it can be hung from trees or fibreglass masts and it gets you on the air, how much power it can handle is a different matter entirely as I have never actually tested this and there is no legal way to do that, however the T2LT gets its next outing at the end of June.

Going back to Tim's video, it is here so you can make your own decision on whether for portable 11-meter operation a T2LT or a commercial antenna is the right choice for you.

The Big Multimode Nets 2018

With 4 years since we got legal AM and SSB in the UK on 11-meters many stations will be celebrating this anniversary on Wednesday 27th June, this will include myself from a very particular place, Tan Hill, home of a very famous pub (remember the Waitrose adverts at Christmas anyone? It's that pub), and that location is perfect for radio, this is also WX dependent though in June snow is not expected, but high winds can pose an issue as they have before when I took a rental car up there and could not open the door.

I've always wanted to operate radio from Tan Hill, I've done a little on 2-meters up there but with little success, 11-meters has been a band I've wanted to do from there for some time as I know, even on an HT with the correct conditions (see my YouTube channel for my pre DX-pedition evaluation) a lot can be received, one thing that is true with radio no matter what the band is that height is might.

Of course I couldn't go without filming it and putting it onto YouTube for all to see, which of course I shall do.

On the day I should be operating between 6 and 11pm (respecting the locals of course though it is isolated up there so the locals are 95% sheep and 5% people) as 26CT730 of course, hopefully on legal SSB subject to tests of my President Grant II which are due to be done anyway, after all this is a celebration of the legal CB modes, of course the conditions on 11-meters on the day will also serve as how many QSOs I can log not just the height.

Although this is a UK big net what I would really be pleased to do is work Roy 104CT011 in Corsica, as he has been on the list of 11-meter operators overseas I want to work for a number of years (other callsigns used by him are 104ET001 and 104DA101), but again conditions need to be favourable and he also needs to be listening to the frequencies.

My contacts will be logged as well so I know how many I have worked on legal power, I will get a logging system arranged as soon as possible.

Operating conditions will be the Grant II, stock mic, and T2LT antenna on the fibreglass mast in the drive on mast stand.

Looking forward to making some great contacts in my first participation of the Big Multimode Nets

A year of legal AM and SSB CB

The end of this month will be the first year of us having legal AM and SSB CB, and a "big net" is planned, so what I plan to do, depending on weather, is take a trip to a high point, Tan Hill or similar, and get on the CB for the first time in a while, the Grant 2 has been idle for a while and needs it's legs stretching, so a trip up to a high point will be good for it.

So, antenna wise, the T2LT antenna dropped through the car's sunroof (on it's fibreglass mast which I will have to somehow attach to the car for support) rather than the orbitor that is already on the car, power, initially I was thinking off the 7Ah battery, then onto the car's own battery later once the 7Ah can't deliver enough power, the car of course can be started and stopped as needed to keep the battery topped up, my Sony headphones will be used to provide a better means of monitoring weak signals as always, the station will be identified as "static mobile".

I may initially set up the station (just on the orbitor) on the 27th at Whashton Road car park just after midnight, though I'll drive there before, and see if I can get any QSOs in, and relocate to Tan Hill later in the day after having some sleep, I may return to Tan Hill on the 28th as well for this, and I hope to get a reasonably sized log of all contacts, I've not logged any CB contacts for a while so this will make for a good opportunity to get some CB contacts logged.

If you are on air across the  weekend the net takes place, give me a shout on either channel 14 mids AM or channel 27 mids USB, I myself will be calling on these channels.

T2LT update


With the new pole having arrived I strapped it to my scooter, packed up my Grant 2, my most decent SWR meter, my multimeter should I need to investigate any shorts, the dummy load in case I needed to check for any issues with the radio, which I did not need.

The pole was not 100% straight (it was propped up), the T2LT was slightly adrift at the top but otherwise fine, a small loop was also provided for tuning. but no tuning was needed as the SWR was below 1.5 at all times, reception was good across both UK and midband, the tuning loop was positioned slightly above the top of the pole with the main part of the antenna running the length of the pole, the choke also worked perfectly.

Should the weather be good on Saturday I shall be heading back up to the car park where I did the tests and will be going on air properly for the first time in a long time.

Grant 2 first look video

As promised, albeit a little belated, here is my first look at the President Grant 2, the day after I took delivery of it.

It took a little longer to get uploaded to YouTube than I thought, it's not meant to be a serious review as the radio has been out for a while now and it has been reviewed by others, this video is mainly my views on it out of the box.

Another video will be done when I get the radio on air


Hope to get this on air very soon.

Grant 2 in pictures

I have a picture of my President Grant 2 in situ on my desk, however I took the picture on my phone so it's not brilliant, there are better pictures of this rig out there and I'll try and get a better picture later

But for now, here is my Grant 2, connected to a dummy load and power meter on UK35 after I'd been having a look at the features the rig had.



















Hope to get this on an antenna very soon and on the air and see how well it works.for myself

G2 day

Well it's Monday and they're usually boring for most but today I took delivery of the President Grant 2, and even though I have not been on air with it yet I am liking it already.

Firstly, it is bigger than I initially thought it was, probably car stereo sized if anything, secondly it has a solid feel, like it's been well put together, which I would expect from a Uniden product (the Grant 2 is made by Uniden for President, some have said it looks a lot like a Uniden Bearcat rig from the US, however it appears the Uniden Bearcat rigs are made in China, the Grant 2 is made in Vietnam).

I received the radio in EU mode so I had to set it up to UK mode, in order to do this you have to turn off the radio, press "F", turn on the radio, and select the UK ("U" on the display), press "F" to save it, turn off, and back on, now if you press "AM/FM/USB/LSB" you get the UK40 along with the new modes on midband, on existing equipment if you want AM you have to set the rig to think it's in Spain, I did this with my Midland 42 over the weekend.

The power lead had, as predicted, bare wires on both leads so I plan to rectify that soon, the rig puts out the expected power on all modes, I tested this with my combo SWR and power meter, I also examined the audio quality of the radio's transmissions on my RTL-SDR while it was on the dummy load, AM and SSB sounded pretty good, though bear in mind that I have never had an SSB rig before, FM was a little quiet but that's ok

Now to test receive, get an antenna on it soon and I'll let you know.

Another shack desk tidy up

With the imminent arrival of the President Grant 2 (this will be tomorrow all being well) the shack desk was in need of a little bit of a clear up, it wasn’t bad but there were things on there that really weren’t needed to be there as I was not using them such as tubes of solder, knife, veroboard track cutting tool, some screws, a hopeless coax stripper (I need a new one) and a roll of electrical tape, as well as my second of my two portable power leads, I decided to leave my Midland Alan 78 Plus Multi B on the desk just in case I may need it on for whatever reason.

I will be recording a “first look” video of the President Grant 2, like I mentioned in previous posts (though I didn’t mention this on the Tan Hill video, but it’s good my YouTube account is getting some use again), on-air tests will come later when I build a T2LT or get a car, whichever comes first(I of course I still cannot install my Sirio GPE 27 5/8 wave as I live in a rented flat and it isn’t a very portable antenna)

So hopefully about 7pm-ish tomorrow my President Grant 2 will be here, a review video should be on here and YouTube by about 9pm at the very latest.

Tan Hill pre-DXpedition evaluation - video

Pre-DXpedition evaluation of Tan Hill

I took a ride up to Tan Hill today to evaluate how good a DX spot it really is, for PMR446 use I’d still advise on an external antenna mounted as high as possible, for CB a proper antenna would be beneficial, though I had stations incoming on a handheld, in this case the Midland Alan 42 Multi, notably some foreign stations on channel 8 midblock using AM. I did have a brief flick around on FM and also on 27/81 but AM appears to show more promise, SSB may also be very promising when I can finally give it a go, which may well be at Tan Hill.

I took some video footage on my phone and while I type this I am awaiting it to process before I upload it to YouTube, a later post will be that very video, which includes my very first call on AM, although because I was using a handheld I doubt anyone was able to hear me but with radio you just never know.

All I am left to do is sort out a shelter, build a T2LT and some suitable battery packs, acquire a pole to mount my antenna to, and hopefully I can get back to Tan Hill and keep DXing, I’d like to be up there in August on a Sunday.

So, a video is to come later one when it is finally uploaded to YouTube, and on Monday the President Grant 2 should be here on my desk.

President Grant 2 arrival–an update

My new President Grant 2 is due to arrive on Monday, as I’ll be out most of that day I have made alternative arrangements for it’s delivery, it will be arriving with a couple of PL259 plugs and 100 meters of RG-58 coax, a lot of this will be used for the construction of a T2LT antenna.

As luck will have it, the courier company responsible for delivering the shack computer’s new motherboard, CPU and RAM will also be delivering the Grant 2, so they should not struggle to find my address.

The first thing I will be doing when I get the package is bringing the radio, in it’s box, into the shack, I will have to clear a few things off the desk first but that is no hard feat.

Now I have a whole weekend of something to look forward to :)

President Grant 2 on it's way

In just a few days time the President Grant 2 will be the latest radio in my shack.  The Grant 2 seems to be the most popular radio for the new legal modes, though in export it can only do frequencies ending 0 or 5.

So, watch this space, my own first look at what is my very first President radio, though not my first Uniden as that was an old Audioline 341 that I borrowed in the early 2000s (who's owner messed with all the adjustments inside in front of me, that same indvidual probably thinks SSB is still illegal), will be on here soon

DXpedition preparations, parts list and rough measurements for T2LT antenna, and a possible cheap and light power supply

As I am hoping to order a 100 meter drum of coax, specifically RG58, I have taken some measurements for the T2LT antenna, I may make a second antenna for home if the design proves itself in service, the measurements are those used by YouTube user UKCBTV, a fellow Charlie Tango station (though can't remember the callsign), with a working centre frequency of around 27.500MHz, should cover the legal 80 channels with little in the way of trouble.

Another thing I found while watching UKCBTV's videos was his excellent idea of a portable power supply, which uses 10 1.2v rechargeable batteries, which range in capacities up to 2500mAh, that would be roughly 25Ah at 12v DC, so something I may cobble together, as well as get hold of a decent battery charger plus some new batteries, he also fitted a volt meter, a good idea to ensure voltage is stable and a cigarette lighter line socket, the battery box and cigarette lighter line socket can be sourced from Maplin Electronics, the voltmeter appears to be an eBay purchase.  This idea was compared to the Midland 77-805 Portapak CB radio, which had a battery box with it, handhelds are another option but the battery life in most is usually pretty dire and the rubber duck antenna is usually hopeless.

The current draw for my Midland Alan 78+ Multi B is around 1.1A on TX, presumably at full modulation, the 42 handheld (which includes a car adaptor) is slightly shy of 1A on TX, the President Grant 2 is 3A on TX with modulation. my Moonraker FA5000, which I now hardly use, I do not know the current draw for as I've lost the manual.

So if I can get the T2LT antenna built and tested in the next couple of weeks, I can focus on a suitable power supply, the battery pack idea above from UKCBTV sounds ideal and is cheaper and lighter than the car jump starter I was originally going to use and will get me started, a telescopic fibreglass mast, and, importantly, a shelter, a collapsible tent may suffice, and a means to carry it all on my back while riding my scooter (I don't have a car yet) then I'm  all good to go, and can get on the air portable at Tan Hill hopefully come August time, if you're on air the day I am up there then we may hear each other on air that day, I'll be using the usual callsign

So, progress in the right direction, power lead, a possible electrical supply, and the measurements for the T2LT written down.

President Grant 2 to be ordered soon maybe? (also a shack computer update)

I may place an order for a President Grant 2 next week if my finances look good, this will allow me to operate on SSB, in particular on my DXpedition to Tan Hill, however I will see what's what.

The reason I chose the President Grant 2 is several reasons, it is the first legal rig that allows you to switch between the new modes in the UK band (this is a recent update to the firmware in the radio), the radio is fitted with a power socket on the rear that the power lead plugs in to, this is similar to my Moonraker FA5000, a rig I hardly use now.

The President Grant 2 is easy to open up to export mode, inside there's a white wire and a jumper block, simply snip the wire and move the jumper, at the loss of your warranty and and your own risk, you also would lose the UK setting but you can get this back by moving the jumper back to it's original position.

It support's President's Liberty wireless microphone, a great idea that no one really thought of in the past, means you are not tied to sitting in the shack or your /p station, you can take a wander if you like, up to 100 meters I think it is, much like a DECT phone or a bluetooth headset.

Another nice feature of the rig is a choice of two backlight colours, orange and green, which also includes a dimmer so you're not blinding youself with a bright backlight at night.

There are other features as well on the rig but I'll do a full write up when I actually get hold of one, hopefully in a couple of weeks all being well

My shack computer has had a new motherboard, RAM, and CPU ordered for it, this would help with performance with regards to SDR use, there are incompatibility issues with the hard disk, optical drive, and existing graphics card, the hard drive has had an adaptor ordered for it to allow it to continue to work, the optical drive will be rectified later as it's not important at this time, the power supply should be sufficient for the new board, the only card that will be fitted is to be the CMI8738 sound card that the machine already has and that is compatible with the board.

Performance with SDR# has been dire with the RTL-SDR operating, the FRN client does work... just, the shackcam feed isn't really reliable on the machine (it's controlled by it both hardware and software, though I intend to replace this with a network camera,, which will make it software and link), and with plans to do the Amateur radio foundation exam as well I want the machine to reliably handle the Echolink software.  Another radio software installed on the machine is Zello, this runs reasonably OK but I tend not to use it as I use it on my phone more than I do on the computer.

Programming my Wouxun KG-UVD1P has proven unreliable with this machine, upgrading the internal hardware may be sufficient to remedy this (the official software, that is practically incomprehensible, works fine, the easier KG-UV commander doesn't read the radio properly, though it could be a bug with the software rather than the computer).

I should be taking delivery of the motherboard and it's ancillaries by Wednesday at the latest, for fitting that evening, which will take out the 446 gateway for a couple of hours but this is no real issue, the RAM on the existing board, if compatible, will be used in the 446 gateway computer to hopefully try and improve things, the GPU in that machine will also be swapped out with the one in the shack computer as I feel the one currently fitted to it is wasted in it and would be useful in another installation.

So, a better shack computer and maybe, just maybe, a President Grant 2 will be sitting on my shack desk soon, but we will see :)

Planning a DXpedition to Tan Hill

I am planning a DXpedition to Tan Hill, home of the highest pub in England, my plan is to take a rig, battery rated around 10Ah, may get a bigger one (my scooter's battery is 7Ah and I need that to power my scooter's starter motor so I cannot use that), or a portable jump-starter with a 12 volt outlet, I just need a collapsible pole and antenna, I plan to make up what is called a T2LT for this purpose.  This is inspired by others going up hills to do this, and Tan Hill makes a good place, I'm sure the Amateurs would like it too, and best of all there's a pub up there for food and drink

Update: Listening to GB3IR, the 2m repeater in Richmond, this evening (I obviously cannot transmit as I don't hold an Amateur license yet) the Amateurs that were on air have mentioned Tan Hill so they actually have used it themselves for HF work, so I am not the first nor am I the last.

The pub itself stands at 1732ft ASL, so the location is pretty much perfect for radio, especially DXing on both 27MHz and 446MHz (I may give the latter a go as well depending on how much charge is in my radios, though I can charge them up prior to the event and take spare batteries, but my aim is to try on 27MHz, as it is sat around spare and it the better of the three mobile rigs I own I will use the Midland 78+ Multi B (the TTI TCB550 is on gateway duties so won't be removed and the Moonraker FA5000 has an awful s-meter and cannot do AM, as AM is now legal and my Midland 78 Plus is type approved for use in the EU as far as I can tell it is legal to use on AM here, for the full 4-watt output on AM, it is required to put the radio into the setting for Spanish channels as these use 26.965-27.405 AM and FM at 4 watts.

My new Sony headphones and my converter will also be going with me, just for those stations I may not hear easily, laptop, maybe, though a notepad would allow me to write down callsigns, I simply need to pick up a portable power supply (a battery and volt meter may be sufficient as a temporary measure until I can get something better), a telescopic or collapsible pole, and an antenna, preferably of the T2LT type.

I may also look into picking up a President Grant II CB radio, as I hear these are very good indeed, and I've wanted a President CB radio for a while now, but until then I will just use my Midland 78+ Multi B.

One thing that I intend to do is take an SWR meter, my good quality Zetagi combo SWR and power meter will be ideal for this role, my cheaper two aren't brilliant, one has a needle that is not as precise as it should be and the other sometimes likes to stick, one of these is connected to my home antenna system for the CB gateway as the radio is also connected to it and I need to monitor if the tuner is working as it should be on occasions.

on PMR446 the antenna will be screwed into the radio, so no meters, coax, or anything else.

If I take the computer I may take the RTL-SDR and use it with another antenna, provided I don't overload it with my own transmissions.

So, I'll post an update as and when this DXpedition takes place, Tan Hill is there, I might as well use it for radio.
