[Elecraft] [P3] and HRD

[John K3TN]

I'm running HRD 5.11 and the P3 with 1.13. Make sure you have the HRD comms
running at 38,400 as that is what the P3 requires. 

There is a different HRD issue, where it cause AGC to be turned off on the
K3, and having the P3 inline makes that problem worse. There is a beta
release of the K3 firmware that looks like it will fix that problem, but my
K3/P3/HRD combo works fine at 38,400 outside of that.
