[amsat-bb] Tracking errors with HRD Sat tracking

[Peter Goodhall]

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)
