[Elecraft] K3 - HRD rig control

[Bill]

I have asked this question previously, and ask again - as updating and 
improving of HRD is an ongoing process.

Have improvements in HRD rig control of the K3 been made that would make 
HRD a recommended buy? Previously, various rig controls were not 
available through HRD and some controls on screen did properly indicate 
selection.

Without taking too much bandwidth - have there been significant 
improvements in HRD rig control of the K3? I am still using an old 
"free" version.

Please note, I am only interested in rig control - not anything else 
that HRD does.

Thanks,

Bill W2BLC K-Line
