I was operating my remote-access Elecraft K2 last week in a short Contest. In the past, I had to wait as much as 1-3 seconds for a single up/down change in operating frequency on Ham Radio Deluxe. This night,  it suddenly became very responsive. I no longer wait, in fact I can now make very quick changes. With this improvement in response, the remote station is now really a joy to operate. I have also used N1MM to make a number of CW Contacts in some contests.

I believe the reason for the sudden tuning-latency improvement is recent version updates in TeamViewer and/or Ham Radio Deluxe.
