Mike, open the 'tuning dial' and you can use the sliders on the right

Peter,
I have been told the same thing about HRD, however nobody has ever given me
precise explanations on what the 'odd quirks' are. 
I have used It for controlling my radios Doppler correction in the past and
it's rock solid. It's just a predefined formula that runs. The same formula
that is used by all Doppler tracking programs. 
The only drawback that I ran into was having no real way to adjust the
Doppler tuning on the fly like you can with SatPC32. It has a tic-box to
enable manual tuning during Doppler correction but it doesn't work. Without
this feature it is literally impossible to use on the linear birds. Getting
this fixed would be a giant leap forward in making it a viable satellite
application.

The issue isn't AOS times matching its todo with doppler correction.

Previously (Not aware it's been fixed) it doesn't allow for proper
calibration between radio and the software so doppler is never correct so
you drift in an odd way.

HRD has always tracked a satellite in the sense of rotator pointing beyond
that, however, it's got/had some really odd quirks.

Before I gave up I used it on FM satellites but for automated control when
using linear it was just unusable.

If there's been some sudden correction recently Mike then do let us know.

(Sorry can't help offer experience to dev, C++,MFC isn't my strong point
more a slap together simple C# apps to interact with apps todo what I want)
