I'm working on a AX44. I can't find anything particular to this so I am using a Cobra 25 manual. I've replaced the electrolytic caps in this, and I checked everything in and out. Most caps were within tolerance, a few double the value, a few out of the game. 4.7 seemed to be the worst of the bunch for some reason.
I've been going over the cap placement and pulled and checked a few just for curiosity's sake. All I have checked are good, no solder bridges, no components with bad connections
I've no receive nor transmit...sometimes. Mostly not, but oddly, when I hold the radio at an angle it sometimes starts working. Receive and transmit. Well, it did for a while, but now I can't seem to duplicate that even. My x-tal is reading at 10.239, as close as you get for 10.240.
Channel 1 has 16.270 and channel 40 has 16.710
Also the PA works perfectly.
Well, it started to work again, then quit. I don't know if it's under the mic connector, or some where on the mixer, pll side. It's just a hit or miss that it kicks in, and I can't duplicate it on a consistent level.
Driving me knuts.
Help? I'm running out of ideas.
voltage(s) chart looks good as far as volt readings.
