[Elecraft] Re: Help with Birdie (not "tweet tweet!") UPDATE!!

Only thing I have in the vicinity is a very weak one at 28696.36. It
exhibits the too-fast and stepping tuning.

But it's sure not very loud. The pre/att setting changes it's level.
Attaching/removing the antenna does not make a difference. It is not
microphonic.

What was really encouraging was that the RX noise picks up just a bit
when I attach the antenna, proving that the RX is sensitive to cover
the internal noise with the ambient off the antenna.
