Attempting to Repair a Uniden PRO500D CB: Part II

Picking up last time where we left off, I bought a mid-1980s Uniden radio off of eBay for around $10. After a quick smoke test, I found that there was no transmit audio or receive audio. I swapped out what appeared to be a shorted 7808 8V regulator and a TDA1905 audio amp chip. The receive audio came back to life, but I was still in the dark with no transmit audio. Still, a step in the right direction.

Hammo Can 2.0

The project that was supposed to be but evolved into something else.

If you recall a few years ago, I built a portable battery box using a $5 plastic ammo can. It works phenomenal with my CB and ham radios. If I need a 12V source to test circuits with, I can also use it as a portable power supply. But what about my original idea?

Cobra 21 LTD Classic Mic Conversion

From one of my eBay escapades, I picked up an older Cobra 21 LTD Classic. It was a really clean radio and I really like it actually! A step up from the Cobra 19 but with Cobra's Dynamike control. I received it without a microphone, however it didn't matter what microphone I tried. I would always get around 20 to 30% peak modulation. What's going on?

Collapsible 17ft 20-10m antenna (PLUS 80 and 40)

 Another antenna plan, this time on a bit of a budget.

After doing so much reading on the Rybakov antenna, I thought it was time to give a go for the lower bands. There are many options for 80 and 40 meter antennas, but a loaded vertical seems to be what I'll be going for. Two custom made coils and a collapsible 18.5' antenna is all you'll need for this project. The result? An antenna that would most definitely be suitable for DX. If Chameleon antennas can make it, then so can you.

LOOK!!! IT'S A BABYCOBRA!!!

Guess what Owen bought himself for Ava? A baby Cobra 19 Mini!
