[Elecraft] Issue with K3 and Ham Radio Deluxe

[Mike Scott]

I have been using a beta version of Ham Radio Deluxe with my K3 using a real
serial interface (no USB conversion dongle).

I enjoy being able to click on DX spots and have the radio automatically
switch bands and frequencies to the spot.

Something strange though, after a session of looking at the spots I have to
power cycle the K3 in order for SSB transmit audio to be intelligible. I had
one report that my audio was so narrow that it could not be understood, this
was to a local with 20 over S9 signal. My suspicion is that I was
transmitting through the 500 Hz CW filter. I don't really know. I formed
this opinion because I brought up the filter management utility and reset
the SSB transmit mode to the 2.7 KHz filter. It was there originally but
when I moved it to the 6 KHz filter and then moved it back to the 2.7 KHz
filter the radio performed normally from that point. Today I had the same
problem after cycling through some spots and I power cycled the K3 and the
radio then performed normally at that point.

Nothing changes in the Rx audio path when this issue comes up.

I couldn't hazard a guess if this is a K3 issue or a HRD issue. However I
remember reading a post here where someone after making changes to
configuration settings that the radio needed to be power cycled for the
changes to take. This is why I tried the power cycle approach today.

Perhaps I cycled through the spots too quickly (I was pretty fast) and the
K3 doesn't have enough time to change states before the next command comes
in and the K3 ends up in a confused state. Okay, I am hazarding guesses now.
