Re: AM/SSB CB WAGNER MODEL-309 SCHEMATIC WANTED

Hi, These were also made as a "Super Jaguar" and also as a Ferris SSB (possibly model SSB6000?). I have a circuit here somewhere, but after 20 years it's probably not too readable / scanable. This chassis is a good contender for the worst SSB radio of all time, so you'll have to be keen to...

Only Ford radio I've seen is a Ford FM-320 UHF set, back in the mid 1980's. They were an optional extra on some models of Ford tractors. Apart from the "Philips" logo being replaced by the blue Ford oval logo, they were identical to the Philips radio. I also had, about the same era, some C...

If the thing has never worked from when you got it, there is a possibility the tx mixer is severely misaligned. Do you have a second CB set or something else, like a shortwave receiver, that can receive a CB frequency? If so, solder a short (1 foot long) piece of wire at one end to the base of the f...

You said: "I can receive distant cb station whit regular level and quality" By that, I presume you mean the thing is receiving OK. If that is the case, then the level of the 20.0150 is OK. If this is too low, the receive will be low too. This also clears the first mixer IC (the one that co...

Like I said before, Ive had a few dead mixer chips die over the years. They are marked "3001" in the earlier sets, and "7310" in the later ones. The GE uses two - one for the VCO / downmix and the second for the TX mixing. The first one is obviously OK, so one trick is to swap th...

First of all, check the supplies. Pin 16 of the PLL should have 5V on it, and the BB supply (middle terminal of the squelch control) should be just over 9V. The most common part to fail in these was the mixer ICs - these have about 10 pins in a single row. They are marked "3001" usually in...
