[Elecraft] K2/100 running Digital modes using VOX...

[STEPHEN W BANKS]

Hello Everyone,

Following several years away from digital modes (I preferCW), I recently reconfigured my K2/100 with a RIGblaster-plus interface using its VOX mode to key PSK31 using HRD.  Don Wilhelm was most helpful in educating me about sound card interconnections to the K2.  I'd forgotten his suggestions and found them most helpful.  

After one very nice first PSK31 QSO using VOX and HRD, the K2 now seems to be impossible to run in PSK without encountering an endless need to readjust the interface level control to provide enough mic drive without also encountering what acts like a need for some sort of antiVOX control.  I have a couple of spare COM ports I could connect the interface to, but using VOX seemed like a good first step (and would avoud cable clutter too).

Since an antitrip control does not exist on the K2 SSB accessory (nor have I ever needed one when using VOX), I reduced mic gain to SSbA to 1 and I adjusted SSbC to 1-1.  My few ordinary voice SSB QSOs all seemed to prefer  that the MH2 be set to the next higher levels of compression and gain; however both settings fared well in signal reports from other hams.

Has anyone ever encountered a similar 'fussiness' over getting a workable combination of level adjustments with his/her K2 using VOX?

Just FYI, I run the power control between 10 and 20 watts in order to avoid overloading the finals in the high duty- cycle digital modes demand.

Any suggestions about where to start chasing down this problem would be most appreciated.  And if you care to share your own settings with me, I'll be glad to try them.

Thanks and 73,
