This is bizzare

Reattaching the wire might have corrected the problem. I don't remember the first post being that long nor the radios swapped out and the problem was still there with the new radio. Might have been a low voltage problem because of the contact resistance. But with the radio swap it would indicate a problem with the amp,

Some times the keying circuits will oscillate and with no carrier input. I had a KL-1000 that did the exact thing. I tuned a capacitor in the HV area and that stopped it.

It could be a bad jumper in your set up.


Sr955 runs off 10g to battery. Amp runs of 8g to battery. That 8g also has the anderson quick disconnect by the amp. So just picture this, when i did the radio swap, the rci 63 plugged into the amp wire not the sr955 wire and still experienced same problem. 2 separate power cords same issue. Something around the battery area had to cause this but idk what? Obviously me taking both power wires off batteries then back on resetted them, but what exactly got reset? Power wires only have fuses, no relays.

Not familiar with what controls your receiver might have, but if you have an AVC or AGC control, turn it off if possible. If all you have available is "slow" and "fast", use fast. I just quickly scanned to see what the problem was, and it sure sounds like an AGC-related one.

What type of battery are you using? I just remembered a similar situation in which the person was using a "Deep Cycle" battery. The different batteries have different characteristics. Deep cycle batteries will put out a limited supply the amount of current to amount of amps for a long period of time, but they cannot supply the surge to start an engine.

If you don’t mind, explain what those features are/do please. But to my knowledge I haven’t seen any of those abbreviations
 
Just a fyi to my initial post, the problem did come back and when i took the power leads off batteries to reset and put power wires back on the problem still exists. Now this is getting irritating.
 
Yea and trying to find that circuit will be damn near impossible. Ugh i hate my life right now.
I don't know if this will help but it is an experience I had with a brand new Icom 7100.
I bought for a bargain basement price and all the dealer told is it will cut out.
I got the radio hooked it up and started testing. I measured the power supply and it was set 13.9 Vdc. I keyed it up into a test load and it shut down almost immediately.
The only thing that I could see is the the wire feeding.the radio looked a bit small.
I hooked my DVM up to the wires right at the radio and the voltage dropped below 10.8 Vdc. That is where the radio shut down was set to protect the radio. I replaced all of the wire and reheaded the cable. I used heavier gauge wire and soldered the connectors and the wires for the fuses to the spade lugs. A couple of hours of soldering wire stripping and the radio was fixed. If you have a meter check the connector right on the back of the radio and see what your voltage does when you key up.

AVC - Automatic Volume Control
AGC - Automatic Gain Control

Slightly different names for the very same thing

"Slow" and "Fast" just mean whether it takes a second or two to start functioning (Fast) or longer than that (Slow).

The operating manual for the radio should contain this information.

    Is it possible to be on a lake and have a homing directional beam being emitted from the shore so a person could navigate to that beam's source? For example at night to a jetty.
