    Cobra 29 channel 19 on 18 sometimes

    I am working on my buddy's 29, he's having problems with it drifting channels. Sometimes he will lose people on 19 flip to 18 and there they are. I have checked the voltages on the 2816 PLL and they are good. Pin 10 is perfect at 5.12 mhz, pins 12 and 13 are dead on at 10.24. Pin 22 is the...

    PC76XL driver and final question

    I have a really nice Phillipine 76XL that had no carrier or modulation. I tested the driver, 2sc1957, that was bad. I don't have any so I figured I would throw in a 2314 driver and 1969 final. BTW, the final that was in there was a 2029. After putting these in I still had no carrier or...

    Connex 3300HP-ZX noise blanker problem

    I am having a problem with the NB on this radio, it doesn't matter what position I have it in, it makes NO difference in the noise level, all 3 positions sound exactly the same. I did do the schottky upgrade last year to it which I liked, I don't think the noise got any worse since doing it. I...

    Ranger VR9000 receive problem

    I bought this radio brand new and tuned up at R & R Communications. The radio worked great but the talkback was wayyy too loud for me. I saw on the cbtricks site for the Galaxy 88 (I think) that you could run a 4k7 resistor from the c154/r207 trace to the c187/r235 trace and it would lower the...
