CB radio on my bicycle, an idea inspired by Jez 2E0IQJ of YouTube channel 2j4ez

I had a plan to run a CB radio from my old scooter when I had it, but this did not come to fruition, I have an old 3/8" threaded snail mount but this has no cable fitted, my idea is to drill a hole through the  pannier rack or use a piece of metal as a bracket to fix to the pannier rack, and put a battery into my old scooter top box fixed to the pannier rack as long as the pannier bag itself still fits.

The radio Jez used originally on his pushbike was a CRT One, a standard mobile CB, because I have a set of wireless indicators on my bicycle I cannot do that, and would like something with a little more handsfree availability I would use my Midland 42, however the PNI offering I mentioned in my last post would also do the job for this and would just need to run off a battery which I can remove daily.

Antennas, I have two choices, the orbitor/springer antenna or the dial-a-match antenna, don't think I'll have a lot of luck with the Extra 48 as it's more for the mids than it is for 27/81.

My bicycle is out of action at the moment as one of the pedals needs a new nut, preferably a nyloc type, I suspect it was one of these but the nylon insert has failed, next time I'm in a local hardware store I shall pick some suitable nuts up once I have the nut for the bicycle sized up again and possibly a suitable piece of metal to fit the snail mount to, it may need a groundplane as well but that I will work out when I can.

Whatever radio I use I will need a handsfree kit of sorts, Albrecht did do one aimed at PMR446 for motorcyclists which I modified to run off a handheld CB as for some reason these jam handheld CBs in transmit despite being wired identical, I still have some parts of this, the main loom with modification and the PTT switch, so I could reuse this with an appropriate headset when I reverse engineer the pinout of what appears to be a DIN connector on the main loom, otherwise new headset to buy.

First up though, fix the bike and use it, and thanks Jez for the inspiration.

Due to past abuse and the ongoing issues that left me little choice to reduce time on twitter and IRC I have taken the decision to keep comments disabled indefinitely, apologies for this
