Not sure if this has been addressed, but probably has. Was spending some time in the 10M contest and worke W5SXD (Hi Rich). He knew right off the bat I was running an SDR1K cuz of an echo in the audio. I have also had other remark about a slight echo.
Any idea what causes this and if it can be eliminated? Other than that, SDR1K played well using N3FPJ software and 1KW amp. Originally was getting lock up problems, but moved my USB port around and added some ferrite beads and eliminated the problem. 73 Greg AB7R
