Palomar ssb adjustment ??

[1iwilly]

does anybody knows if the Palomar 300A base amp, relay shatters when been us in SSB mode, is there and adjustment to hold it a tad longer while talking and not sound like morse code

That's usually a capacitor that controls the latch time.

It looks to be a 22MF cap there now, bottom left corner. you can check the value and if it's bad, replace it or move up a couple.But I'm just guessing here.

bottom left corner of schematic, the 22uF cap.

Put a 1000-2200uf cap there

We've been supplying a 47uf cap in the 300A cap kits we sell on fleabay. Haven't heard a complaint yet.

well, today i got a chance to look at the bottom of amp no 22uf i believe the 1000uf is the correct place for ssb ???

the SSB cap is on a small board with 3 relays on it seen from the top with top cover off. Here's 2 examples.

I may be mistaken, and it's no secret that I am no tech, but I think I recall a sensitivity adjustment somewhere in the 300A ... Am I wrong?

I have never seen a relay shatter when used on ssb. Good thing there is a cover on the amp, a piece of it might fly out and hit you in the eye. You got issues

street language relay clicking off and on. electronic term= latch time. never tried on SSB until a few days ago. got my answer from the previous owner today he wrote
When you key the mic on SSB you get no wattage until you speak. The mic will pic up room noise which you can see on a watt meter and it appears as a small carrier. It's not enough to hold the relay open so the amp goes click click click. If your on SSB mode and you key the mic just talk. The click click click problem will go away. When your done talking un-key the mic or guess what.......... the relay will try to release and you will hear a click click click all over again
