K3 & Ham Radio Deluxe Ver. 5.1 Serial Communication Issues

David S. Mulvey
I am having trouble with the new Ham Radio Deluxe Version 5.1 software release. Since I upgraded to 5.1, my Windows 7 PC and HRD will communicate using the Elecraft USB/Serial cable as evidenced by seeing the K3 frequency in the HRD K3 emulation screen.  However, after a few minutes the K3 emulation locks up and stops communicating with the K3.  

I am using a K3, P3 and a KPA500 all with current firmware, at 38.4 Kbps on USB emulation Comm 6, when the HRD K3 emulation locks up, the Elecraft K-Line continues to communicate among themselves correctly.

Has anyone on the forum made the HRD 5.1 upgrade and if so, how do you have your Comm settings set?

Thank you in advance for your ideas and help!

Running HRD 5.1 build 3209 on Win7 x64, COM port on mainboard.
K3 Firmware: DSP 2.73 MCU 4.47 DVR 1.03 Front 1.15

HRD > Tools > Program Options > Comms:
- "Read timeout" 500ms (default)
- "Switch off" enabled
- "Polling" disabled
- "Display timeout warnings " enabled
- "Dual VFO tracking" disabled
- "Refresh interval" 200ms
These settings were probably inherited from HRD 5.0 when upgrading to HRD 5.1.

No issues at all (so far)...
