[Elecraft] K3 HRD control of features

[Bill]

I have used HRD in the past with several rigs - all quite successfully. 
Now I am using it with the K3.

It seems to me that there are very few of the K3's many features that 
can be controlled via HRD. I would consider HRD version 6 for purchase - 
if it is to become K3 feature rich. I posed the question to HRD support 
and received the following: "We support whatever Eric has in the cat 
commands, if it's in there, we support it."

Currently I am also testing N4PY's software for rig control. I know 
little about this software - only used it a couple times today. I have 9 
more days on the free trial.

Perhaps neither is suitable and I should continue twisting knobs. 
Comments regarding both programs would be greatly appreciated.
