You missed one. The CSN Technologies S.A.T.

I've been doing sats since the 1970's, and there is nothing else like it.

With an IC-9700 and G-5500, you don't need anything else (except a PC or an iPhone to control it wirelessly). It tracks, it dopplers, it shows the next passes for your selected favorite sats. TLEs are updated at the push of a button. It memorizes RITs for each sat.

It makes operating the sats a no-brainer. All for under $200.

The only thing I use SatPC32 for now is predicting footprints.

Does anyone know if the Chinese knockoffs (COM-232B or USB-232B) are suitable replacements for the GS-232B AZ-EL rotator controllers?  If not, is there anything more economical than the GS-232B, yet equally functional?   

Thanks,
