[Elecraft] K3 and HRD turning AGC off

[Courtney Krehbiel KD6X]

I also have been having problems where the AGC suddenly shuts off while using
HRD V.5 with the K3/P3 combination.  It's not caused by RF because often
this happens when I'm not even in the shack.  I did find what seems to be a
solution for me, so I thought I'd post back and hopefully help others
similarly afflicted.  My ah-ha moment came when I looked at the P3 manual
and realized that the RS232 path to the K3 went through the P3.  (Figure on
p.13 of the P3 manual.)  The communication between the P3 and K3 is always
fixed at 38400 baud.  However, the communication between the computer and P3
can be changed.  My  HRD to P3 link was originally set at the default of
38400 baud.  I used the RS232 menu selection on the P3 to set the speed to
9600 baud and made the same corresponding change to the connection
parameters in HRD on the PC.  I haven't had any problems with the AGC
dropping since then, and I haven't noticed any significant differnce in the
functionality of HRD's ability to control/read the K3.
