It's still got the 5 pin socket.

All this time I had to help my Mom and Stepdad move to New Hampshire. Now that they're gone I can get back on the radio. I talked to a friend of my Dads and he and I met at my Dads shop. He told me it sounded like feedback, and he said to spray some contact cleaner in the volume control...

I am confused. It's not the first time so I'm kind of used to it. I was checking grounds to the chassis and everything was .8 meg ohms and climbing. So I checked from pins 7 and 8 at IC6 to the ground side of C172, and it was .6 ohms. Aren't all these grounds supposed to be to the chassis? Maybe...

I'm taking one radio with me, and giving one of the other radio's to my daughter. I'll tell her if the skip is right, expect a call from me.

I saw on the news it's only a cat 2. The closer to the coast the worse it'll be. Is your tower easy to take down? If you do take it down, I would think you'd need to anchor it some place.

I found some headphones at my Dad's. Plugged them in and got the same squeal, but just not as loud as the speakers.

The only headphones I have are USB. LOL

I tried bridging pins 4 and 5. It does transmit, and of course the noise goes away when it transmits.

Those were the points I was testing with the capacitor. I also unplugged the frequency counter and still have the noise. I'm gonna end up scratchin' a hole in my head tryin' to figure this out. LOL

Thank you very much. I really appreciate this.

When I unplug the mic there's no noise at all. When I bridge pins 2 and 3 the noise comes back.

This is great, but what I've been looking for and really need is the board layout of the bottom of the circuit board. I've got a 16volt 1,000uF cap for testing and I think I got the right solder points. The points I tested I ended up getting the same squeal. I'm hoping I got the wrong solder...

Now I'm confused. LOL I thought I was supposed to bridge pins 2 and 3. I'll go up to Dad's and try pins 4 and 5 next.

I checked this and tried a different mic, it was the same thing, no help. Thanks for the advice though.

I did that, bridged pins 2 and 3 and I still got the noise. With the mic disconnected there was nothing, which is right. So I'm sure the mic is wired correctly.
