    Converting CB Watt/SWR meter to 40m

    I have a ASTATIC 10/100w meter that was orginally designed for the 11m band. I have a better one for CB now, and would like to use this one to test 40m QRP amps and transceivers. Super accurate isn't important, I just need to be able to prove that I am making positive changes when I build or...

    CPI pre-amp 120VAC for CB

    This thing works great. I have two of them but can only use one at a time so one has got to go. Adjustable gain, really adds ears to your base setup. I've seen these at swaps for around $80. $60 Shipped/OBO Money Order for payment, sorry no paypal.

    139 XLR (858SSB) RX/TX Issue

    I did a full recap on this radio (was working well before) a few weeks ago and just pulled it back out to check it. It appears the intermittent issue I was having after the recap has gone permanent. Here's the series of events that led here: Electrolytic C94 was installed backwards during...

    President Madison won't power on

    I hate the name of this radio. Nearly impossible to find anything on Google. Anyway, this is another base station I got from a super deal a few weeks ago. It did not come with an ac power cord so it's plugged into a power supply at 13.8vdc. Will not do anything when the volume switch is...

    Converting old president grant SSB 5 pin to 4 pin

    I'm not going to order the adapter plug because I have spare 4 pin sockets. I got this radio without a mic but it powers on and everything seems to be working as far as I can test it without a mic. I've done a lot of searching and it seems I need to join pins 2 and 4 (shield and switch wire)...

    Help me identify this box please

    Really not sure what this thing is. I got such a good deal yesterday on 2 generations worth of CB equipment from a widow on craigslist for $75. Bunch of pre amps, antenna switches, ext speakers, 3 portable SSB units and 5 base stations. I also got this small enclosure that doesn't have...

    Nightmare Property for Antenna Placement (HELP!)

    So I just got my tech license and am modifying a Cobra 139XLR to play on 10M and CB frequencies. I was able to procure a NIB 1970s Avanti Astro-Plane Antenna which is 12' tall but 8' of it hangs below the top of the mast. This antenna radiates from the top at an upward angle. I'm planning on...
