I made several 40 SSB contacts today, some under strong, good S/N condx. Everyone said great audio, no echo or hum. Still, I have the echo and grrrrr in the monitor.

Bill - I recommend you open a HelpDesk support ticket on your issue so we can investigate further.

Thanks Tim.  Dudley sent me an expedited RMA number and shipping label yesterday.  I boxed my 6300 along with the Heil mic cable and ferrite beads (in case there's any question about the cable) and dropped it at the UPS store this morning.  Thanks for the great support.

Have to say Flex service is pretty impressive.  I am sending mine back for a look as well.

One thing folks having audio issues might want to consider is building a terminator to act in place of the microphone. An open mic line could pick up random shack stuff (monitors, etc.) and provide a low-level of modulation. With a resistor (of mic impedance) using short leads in a shielded shell, you might see some improvement. At least for testing to rule out radio issues.
