    Pix Request, 148 GTL / Grant XL

    Leap, the bias diodes are different, and why the readings arent the same. According to Rick Jackson's schematic on cb tricks for the 148, the driver diode is labeled d50 and is a MV1Y.. The final diode is labeled d49 and is a MV13YH. I remembered thinking the same thing one time while...

    Cobra 29 nw ltd classic, no receive.

    I just repaired a 29nwstwx with a seemingly similar issue. TX worked as it should and WX worked. Rx signal and audio, worked..kinda, but was very very faint. One of the rx tuning cans, I assume, had a bad solder joint. I could press on the cans with my finger, and rx would return. I resoldered...

    setting up a radio work shop

    Daddyo, these guys arent trying to discourage you, so I hope you dont take it that way. But "just trying to get by with this" doesnt necessarilly work with radios. Thats all they're saying. Take your time, and read..alot.. But a dummy load is essential, as has been said. Should be the first...

    Uniden PC-122 stumped

    Those cobra 19 ultras have small pcb boards mounted to the main pcb. Try pushing around on the small boards and see if sound comes back. They're known to have bad solder joints where the smaller board mounts to the main pcb.

    29LX alignment procedure?

    Does the new cobra 29 lx's ('14-'15) use the same alignment procedure, test points, etc..as the older ltd's? per cbtricks. I havent messed with the newer models much, and just wanted to confirm before i get started.

    How much?

    Diddo on the grants. I got my grant xl in near perfect condition (only minor scratches) for like 40 bucks! They're not talked up like the 148's are i guess, and were still being produced till the early 2k's iirc, so they're not as hard to find in decent condition.. right now anyway.

    Antenna analyzer?

    There was a comparison review online I read a while back, but I cant find it now. It compared the "lower end" or "entry level" type analyzers. Rigexpert aa30, mfj 259b, palstar zm30, sark 100, and the feature tech aw07 were among the analyzers compared. It led me to believe the rigexpert to be...

    Cobra 29 channel 19 on 18 sometimes

    Does it do it on any other channels? Or just 19/18? If not, channel selector gets my vote. Most likely just dirty if its an older radio, or been in a dusty enviroment... If its all channels, could be just a cold solder joint shorting out near the vco area. just my .02

    midland 5001z audio

    IIRC the modulation vr was marked "mod". It should be rv2 or d10 is the limiter according to another site. But I wouldnt turn on it too much. Or clip the limiter. I ended up turning the one I was messing with back down. It really muffled the audio when turned up, and sounded like chit. The...

    FC 30 Freq Counter Question

    If the fc30 is like the galaxy 347/390 external counters, it will work. I wired a fc390 to my grant xl. There was a jumper inside the counter I had to remove..or add...I dont remember which, but it works(y) Id have to do some searching to find the procedure, but I remember it wasnt that difficult.
