Strange sound

[K5LAD]

Hi Gary --
I checked today and my "CW signal" is gone, or at
least, changed.  I now have a weak constant signal
which does not change pitch (without turning the
knob) and I hear it on both receivers so it's
something different.  It is also there with antenna
removed.
It's not in a place that causes a problem but I was
just curious since it seemed so strange and out of
place.  Note also that I turned off everything else I
had running to make sure I wasn't hearing
oscillators from something else.

Thanks for the comment and I'll keep listening but
not bug the reflector about my odd occurrences.

73,
Jim - K5LAD

BTW - The NR was off when I was hearing either
oddity.

Hi Jim.

I have a fairly weak birdie there (well v close), a
solid carrier not
12 WPM CW.  Can hear it on the subRX as well.

Were you using the NR I wonder?  It can
sometimes make stuff sound
like it's comin n goin.

Hi Jim:

Say hi to your first birdie. Mine is at 29.492.070 and is also present on
both the A and B receivers. I have approximately 2 birdies per every 100KHz
on all bands.

There's a software suppression feature which you might like to try. It's
under CONFIG:SIG RMV and its use was described in the release notes for MCU
3.03. I don't know if it's also in the latest manual. I personally found the
birdies to be easier to tolerate than the software fix for them.
