[Elecraft] KX3 Transmit audio has (unwanted) echo effect

[Jim Kutsch, KY2D]

Thanks. I already tried that and the DVR recordings sound absolutely fine.

Two other things I didn't mention in the initial message: the echo still
exists with the monitor off and I'm using a KXPA100. The echo is gone or at
least much less obvious without the amp. I'm thinking RF is feedback into
something somewhere but if that's what this is, it is causing a very strange
effect.

Record a sample on the DVR and play it back to hear what is going on.
