I have had consistently good success with the Doppler correction in HRD. I
use it to guide either two FT-817NDs, or one 817 and a FT-857D. However, I
have encountered issues with what I believe to be the load on the Atom
processor in the Acer netbook I use.
Even though Simon has noted here and elsewhere that the Satellite tracking
program is now "stand-alone" in V 5.0, I cannot connect radios to it without
first launching HRD and connecting to it. That appears to result in issues
here. I have had the netbook lock up multiple times, including times when I
was about to attempt some low-angle DX contacts on grand old AO-7.
I continue to use SatPC 32 here because I don't have those lock-up issues
with it. The program runs flawlessly for me, and I have seen posts here from
other operators who have similar consistent success with SatPC 32 and the
I continue to hope that some future version of HRD will, indeed, make it
possible to use ONLY the satellite tracking program - without the need to
first connect radios to HRD. It always has been possible for me to work
digital modes through DM780 without launching HRD, so I hope that kind of
independence will become part of the satellite tracking program in the

I would like to share an experience and ask this board if others have the
I have used Ham Radio Deluxe for two years but have recently switched to
SatPC32. The reason is that the Doppler correction of HRD with my
Yaesu FT-847 always gave problems. It was a constant battle to stay on
I would like to continue using HRD but the Doppler correction compared to
SatPC32 is just bad.
Now I wonder, are there others that use HRD that share this experience
or is it something only occurs in combination with the Yaesu FT-847 and
is there maybe a solution.
