I am not so sure its the echo board....

I removed the two top right hand brown connectors off the echo board and then inserted a very short wire to the two brown connectors after removing them from the echo board.

Picture the two connectors side by side laying flat next to each other. The inner pins which would be directly next to each other is where I inserted the short jumper wire.

This allow me to key the radio without going through the echo board. I did not reconnect any audio wires.

After making this connection, the growling cam back. I quickly keyed the mic and I was able to transmit. But as soon as I release the mic key the growl came back.

So just a guess with my way of thinking, I don't believe its the echo board
at all causing the growling???

Attached video and audio of the noise.

Any thoughts???

Again Thank you,

RF Krazy
