Pole for T2LT ordered

I have put an order in for a suitable pole for the T2LT, though this pole was advertised as being a flag or windsock pole it would work fine for having a piece of wire attached to it, this will allow me to tune down the T2LT to a suitable degree, though the SWR may change on location but we will see.

The tuning will be done using my President Grant 2 off either the battery pack or the scooter battery, as I don't plan any proper QSOs, I will simply erect the pole and antenna, and either prop or fasten it to a fence post, I will find some velcro straps to allow a temporary fix to the pole, and a small cable tie to loop the top section for tuning, all I have to to is adjust this loop.

I intend to use the most reliable of my 3 SWR meters for this, the meter in the Grant 2 may not be accurate but will be on to see just how accurate the onboard meter of the Grant 2 actually is, also out in the open the antenna should receive across all channels, and also all modes now we have multimode CB, I look forward to finally seeing if my third antenna attempts (I made a dipole a few years ago out of a piece of coax (but forgot the choke), the coax being used later for the ill-fated inverted-V, the T2LT uses one component used in the ill-fated inverted-V, half of the choke core, it was integrated rather than detachable.

I have confidence this antenna will work well, but I have sufficient coax to make another should the need arise.

T2LT progress update

Today, as the weather was nice, I dug out the beginnings of my T2LT antenna and got to work measuring it up and finishing it off, though I have yet to tune it yet.

Tuning will take place as soon as a suitable pole can be acquired, the pole MUST be a fibreglass pole, a carbon or steel pole will upset the antenna and make it useless, given how busy I have been of late with other things it's been a bit difficult to find time to get the T2LT sorted, hopefully I can get it tuned down and it will work nicely, a temporary solution to a problem I shouldn't even have and perfect for hilltop DX, which I hope to do before the weather starts to turn bad, so I'll get on with it sooner rather than later.

Also it's a couple of weeks to go before the Amateur radio club supposedly starts, I will still be going to Colburn that evening but if it's a no-show there is not a lot I can do about it, but if not then it's progress for me.

So I most certainly will be on CB soon, and possibly the Amateur bands not long after.

Follow up to previous Amateur radio club post

So I returned to the Post Office where I saw the information the following day and bothered to take note of it, the date was 18th September with a start time of about 7:30pm (or this is what I put in my calendar). and it will be taking place in Colburn, if they do not offer training of any sort I can simply go to Bishop Auckland anyway, but to have an Amateur radio club closer where I do not have to travel miles is a great help so it will be a bonus if they do offer the training and I can get my foundation at the very least, maybe even my intermediate, aiming for full license by 2015 if possible, though it could take longer depending on what my employment prospects hold.

So, about a month or so to wait, and I'll be able to begin my journey to licensed amateur, it's been a few years in the making but it might well be happening very soon, also it will allow me to meet new people who share a common interest.

So let's see what happens

New Amateur radio club possibly starting in local area in September

At a local Post Office today, one that is at the very back of a Co-Operative supermarket, I saw a flyer for what appeared to be a soon to start Amateur radio club in the village of Colburn, a stone's throw from my current work, and about 15 minutes travelling depending on traffic, weather, and other external factors.

Their first meeting is scheduled to be a date in September, when this is I did not record as I had other things to do such as make my way back home after work, however it does mean that for general club activities I do not have to travel to the Bishop Auckland club at Stanley Crook, I may still have to do this for my exams however, though this is a one-off hassle per exam, I now have a target set, get my foundation license by the end of the year, I have the "Foundation Licence Now" book, so I suspect I am best getting to the revision again.

I am very pleased by this turn of events, and all I intended to do was post a large letter and pick up something for dinner, I will be going back over to the Co-Operative store in question to get the dates noted down in my phone, it's an opportunity to get more involved in the Amateur side of things, I may as well take advantage of it, and with a bit of luck you may hear me on the bands and GB3IR with an M6 call, of course I'll still be on CB and PMR446 with my CT callsign

I'll update this with more soon

Portable power pack completed

Wednesday lunchtime I had arrived home, and found the postman on the estate already out delivering mail, I had got to the home QTH before the postman could deliver my mail, once it did come the combined volt and ammeter for the portable power pack had arrived.

The voltage is displayed in red on the top row, the current in Amperes is displayed in blue on the bottom row, with no load the display will show 0A, it is rated to 10A if simply wired in line with the negative side of the circuit, I don't expect a current draw above 4A at most.

I may regulate the output so that the voltage at the cigarette lighter terminal is constant, however the radios are working without regulation though they are down a little on TX power though this should make very little difference

So, just to finish the antenna off and get it on a pole

Portable power pack almost done

This morning all 10 of the batteries were completely charged up, I have on order a dual voltmeter and ammeter (voltage and current measurement on the same display) so I can keep an eye on both current draw and battery state at the same time.

The batteries will be going in the unit shortly so tests can begin to make sure it will handle various loads, specifically CB radios and, for power cuts at home, phone chargers, also to see what voltage these particular batteries really show on the output (they are Maplin 2400mAh rechargables), some batteries may show 1.25 V at the terminals, that's about 12.5V for 10 batteries, some may show 1.3 at a full charge but this could be very rare (it would give 13V).  During the tests a basic multimeter is to be wired across the terninals to check voltage.

So I shall get on with that and report back later

Portable power pack under construction

Since I returned home last night I have been working on a portable power pack that uses 10 AA size rechargeable batteries for portable work, inspired by 26CTX104, I have made the design as such that it is enclosed, the battery box can be detached from the cigarette lighter socket by removing two screws.

The batteries themselves, currently, are Maplin 2400 mAh rechargables, at around 1.2V per cell to get the required 12V, I suspect combined capacity is 24Ah, based on my theory that there's 10 of them, and 10x 2.4Ah is 24Ah (2400mAh being 2.4Ah).

A voltmeter will be integrated into the design later to ensure there is sufficient charge in the batteries at all times, nothing worse than running out of power mid-QSO.

So, I have another 6 batteries to charge and my charger only takes 4 at a time, so I best go do that and I'll post and an update later on
