[TenTec] Omni-D with an Annoying 1khz Tone (MadScientist)

[forum4ll at verizon.net]

Pete,

It is possible that this maybe a "feature" but the owner and I feel that
it shouldn't be there. It gets a little confusing tuning into CW or SSB
with that tone in the background. It does disappear with a strong signal.
