    In case you're wondering if you should remove the glue...

    ouch Brandon that had to hurt the ol' ego a bit lol. i still find candle wax in tuning cans sometimes. People really need to stop doing this. you can buy more bees wax than you'll ever need for less than 10 dollars on amazon...

    Surface mount Cobra/Uniden swing mod help

    ok if this board is the same as the one in your 29LTD, then look for D404. its that big black rectifier diode right next to the modulation transformer. Since all the part numbers are different as well as the board layout, we should confirm that it's actually the right diode. We can do this by...

    got a picture of the PC board? LC

    Cobra 2000 GTL Restoration

    thanks for the kudos Dave! W5NPJ, I would be happy to do the work you need done, but know that i am about three months backed up with radio work right now. If you would like to discuss details please click on my name over on the left and choose "send a direct message". LC

    Unit 399 JJ in Medellin Colombia

    This is so sad to hear. I am very proud to have called Jim a friend for 20 years. Over the years we've exchanged advice, stories, and even equipment. We never got to hear each other's voices except for one almost QSO where we confirmed on the forum the next day that we'd heard each other but...

    Modern Equivalent for UPD858 Relay?

    So what are people using these days when needing a replacement? yes, 12v 3PDT relays can be had for 5 bucks on amazon but i think the pin spacing footprint is different. I don't have one in front of me right now to measure and confirm so i thought i'd ask the group. thanks in advance! LC

    New (new-ish) Texas Ranger TRE-2639

    An AM only radio with a dual clarifier? that just don't make no sense! and that RB-AM-CH19 switch? WTF is that about? Seems like someone at Ranger asked, "what are the absolute cheapest bells and whistles we can add to the front of this radio?" My official review? Lame. LC

    Realistic TRC 457 heats up, drifts, un adjustable

    many times when your alignment get more and more off the more you turn the channel dial, its the 10.240 crystal that is the issue. LC

    Carl the Christmas CB'er

    A very Merry Christmas to all my forum friends! It's hard to believe that at this point, some of us have known each other for over 20 years! Here's hoping everyone gets a new electronic gadget under the tree this year! LC

    Realistic TRC 457 heats up, drifts, un adjustable

    ok well then that's not the problem. I apologize if this seems pedantic but have you done a continuity test from the body of that transistor to the metal chassis of the radio? LC

    Realistic TRC 457 heats up, drifts, un adjustable

    VSWR, something you said in one of your posts prompted me to ask, what color is the heat sink compound you are using? you said "top of the line CPU compound" and many times that type of compound is conductive. if the compound you are using on that TO3 transistor is grey/silver, then i would...

    Realistic TRC 457 heats up, drifts, un adjustable

    ok that's the power supply. Something is wired wrong, or a bad component, or maybe that transistor was mounted improperly and is making contact with the chassis? (i would figure that would pop it but maybe not) LC

    Realistic TRC 457 heats up, drifts, un adjustable

    Are you talking about the TO-220 transistor that is mounted to the shield wall of the PLL section? if so, there is a TSB on this. It involves moving that transistor (TR36) and a resistor (R153) to another area where it can be connected to a heatsink. move the resistor as well and solder it to...

    Schottkey diode/transistor opinions

    Mike, what radio is that with the dual gate mosfet front end? Brandon, dual gate mosfet front ends were the dream for many people about 20 years ago or so and there was a guy named Bill Good who designed a way to mod the 148gtl/2000gtl to use one. I never saw one but apparently it worked very...
