When you define a Satellite within HRD v4 and also v5 you have the option to select for frequentie and doppler correction:

- Repeater / Split or - Linear inv, transponder

What should I choose when defining for example SO-50, AO-51 or AO-27?

I have no problem with AO-7, VO-52, FO-29 etc etc.

The reason for asking is, that I have a lot of problem with working SO-50 in the combination Yaesu FT-847 and HRD Satellite Tracking. At first I thought it was an CTCSS problem, but it seems that I am of frequentie :(

Any help would be appreciated,
