RV4 http://www.cbtricks.com/radios/cherokee/cbs1000/index.htm 1 watt dead key is probably as low as you'd want to go.

I PM'd a pic. Mine is the 70's style that sweeps up higher in pitch as it fades out and warbles if you hold the switch down.

Oh, yeah... :confused: I think it's past my bed time.

Yes, I've had it for years. Got it out of an old worn-out TUG-8 D-104.

If it's the original tweety bird from the 70's with the momentary push button switch with a capacitor across it, just make the capacitor higher in value. I think the stock cap is .047uF

From my experience, when I see a combiner resistor on a 4 pill section that's burnt that bad, it's more than just an imbalance from a cap. It looks more like a transistor is bad in that section.

Here, I fixed the image URL for you: ;)

Crystal radio? ;)

I think it pipes the CB receive through the PA speaker.

It's also "gold" (pee yellow) colored, lots of cigarette tar.

Welcome!

It can happen because when MOSFETS go they almost always fail with a drain to source short (at least temporarily until they explode). This of course shorts the regulator to ground taking it out as well.

I usually change C154 to a value that I'm able to get 14-16 watts PEP. That gives the radio a reasonable output while still limiting. The SSB on that chassis has very good sound and the fast attack characteristics of the ALC circuit makes the limiting action virtually inaudible on the receiving end.

On some of the 858 SSB chassis, the ALC circuit has too much gain and CT7 doesn't have enough range to null the feedback for full SSB power. Try lifting one end of C155 (1pf disc) and see if you have full power. If so, that is what is happening. To remedy this, put C155 back then change C154 to...

The one you have is obsolete. I did a little searching and I found an SMD inductor from the same company at Mouser. They don't make one that's 4.7uH at 175ma any more but there is one in the same size package that's 4.7uH at 1.3A. Your original...

Same as Midland 4 pin: Stock 1- Audio 2- Shield 3- Receive 4- Transmit

That would be great for throwing musical carriers on yourself! :rolleyes:

Did you capture a video-gate of it laughing at you? ;)
