Hi Clark. The ringing in mine appeared to be due to just a tad
too much rf gain (or if gain,not sure which). They would almost
go into oscillation after extended transmit periods.
The "Sleeping" was apparently a software glitch. The thing
would just go dead after a while, and the only way to wake it
up was the on/off switch. The new firmware has eliminated that
problem. de KL7HF
