I recently picked up a Cobra 139XLR in decent condition. It received and transmitted both am
, but output and modulation were both low. I got on CBtricks to get the adj. points for the radio, and when I started to adj., I started with VR8, which said it was AM
power. I started the adjustment into a dummy load, and the power started to come up to around 5 watts. So I said, Cool. But when I keyed up next time to recheck it, I had no power or modulation. Relay kicks, and I did clean the contacts. Receive is fine. Changing the adjustment makes no difference. That was the only adjustment I made. When I key up on ssb
, the radio clicks and the lights dim, kinda like a short?
Can anyone out there clue me in to what I did? Seems everything I touch lately dies. Im afraid to take a leak!!
Incentives are important.....I learned that in rehab!
