    NEW blue face magnum delta force

    The new version is called a OmegaForce and has the blue LED's, 2 ERF2030 mosfet finals, and speech proccesser and the topgun modulater from the factory. That would be the best way to go. I bet that link is probably old. They dont make the delta force anymore.

    Magnum s-680 mod needed

    Not going to be easy.. you would have to reprogram the MCU and tell a pin to do that in the code of the chip. It is not something most people could, or even know how to do.

    Ranger 63FFC4

    I had the opportunity to work on one of these, and the only complaint I have is that it has a memory battery.. I havent seen one of those in a radio for at least 15 years.. As for the rest of it. it worked pretty good.

    SMD

    ranger has made a lot of radios that are all SMD. They are generally not accepted well by a lot of shops. I am guessing its because they have a hard time keeping that radio shack soldering GUN from hitting all they traces at once... lol the cobra 200 and 150 are all SMD also.

    Galaxy 2527

    I hope you paid very little for that radio. It most likely has a bad CPU. Good luck finding one. The resistors go bad after the CPU takes a dump.

    utb-1 talkback

    The voltage should be 13-14 volts DC. What kind of radio are you hooking this into? Generally when there is a distortion heard it is due to poor ground. I would try hooking the ground somewhere else and see what happens..

    Erf 2030 ?

    Thats a kewl pic. I have seen some 2sc1969's with a huge hole in them, and TA7222AP audio amps with giant parts of them missing.. and some 2sc2879's that had the tops blown right off them ! it's amazing what a semiconductor will do when the fuses are jumped out and the conditions are right ...

    Any mod for RD16HHF1 in Cobra 200 GTL ?

    I have found that usually turning down the bias a lot lower then where the factory has it adjusted will make it last in there. I think they just have it turned way too hot to last. I havent seen anything that is easy to do to replace it with. You can use the ERF2030, but you have to bend the...

    Question for radio tech's

    I would take it to somone else that is familiar with CB's, that radio is the same as a lot of others and someone that does it everyday RARELY looks at a schematic if they have been doing this for a while...

    Cobra 2000gtl ssb problem.

    If the problem is on both USB and LSB here is what I would suspect. It could be the carrier OSC. out of tune as mentioned in a previous post by Molecule, Or there could be another problem. On AM the Final and Driver are "turned down" to about 6 volts or so (depending on what the carrier is set...

    switcheable bias 1x4

    I was just wondering.... If this has Bias other then class C, then why does it look like it still has wire wrapped ferrites going to ground off the back of the input wideband transformers? Am I missing something here? Or were these pictures taken prior to actually hooking up the bias circuit? I...
