Dear group,

 

At first I thought I did not have any noticeable birdies, but now it seems
that I have developed a few.  It's probably from moving cables and such
around inside the rig.

 

When I tune quickly through a band, I can hear solid tones that change in
pitch as I move up or down in frequency.  The weird thing is, they don't
behave like I thought a birdie would.  In my case, disconnect the antenna
and the tone practically disappears below the noise floor.  Reinsert the
antenna, and it comes back.  Also, switching from my antenna on ANT1 to the
dummy load on ANT2 or the RX connector removes the birdie as well.  

 

The NB has no effect, but the notch feature does.  For example, moving the
notch to 2700Hz wipes out a strong signal tone on 28.380

 

I haven't tried the birdie mapping feature yet, so I thought I'd ask. is
what I'm hearing considered a birdie in this case, or just DDS signal noise?

 

73,

James KC2UEE
