I completed my K2 earlier this week and everything seems to be working
great. However, I have discovered one problem. Received SSB signals from
7180 to 7185 kHz are garbled even with the NB and preamp off. Thus far I
haven't observed this problem on any other frequency. Any ideas what may be
Dale,
That is an old problem often referred to as WAOF (Weird At One Frequency).
That frequency region is where the PLL frequency and the VFO frequencies
cross. Those two signals can couple together producing the condition
that you observe. The fix is to reduce the opportunity for those
Hi Don,
Electrical tape is slightly resistive, at least the ones I've used. At
Idealab (Pasadena, CA - tech incubator), we used electrical tape to
lightly ground sections of a proto RF PCBA we were developing. Doing
this snubbed out some parasitic oscillation that we never really
understood. One

Thank you so much Don, Those are excellent suggestions and I will get right
on it today. I feel some comfort in knowing it isn't just my radio. In other
words, misery loves company. :-) --Dale

Be aware that most black electrical tape is very slightly conductive.
