I have been successful with the VX6, no need for Doppler or full deuplex, just program in the channels for every 5 khz on the receive, in the range of +/- 1- kHz, and tune manually during the pass. Manual solution, works well without the need for detailed Doppler. Besides, on the FM repeater birds there is some FM "capture effect" which is to your advantage...no need to be spot on for the receive freq

I think the new Yaesu VX8r is full duplex. I recently purchased one, but haven't had a chance to get on the FM voice sats with it yet, to see how well it works. It does run APRS well with it's add-on GPS, I did get it to digi via ISS. I can't wait for it to get warm, so I can do some more stuff outside!

I'm getting started in satellite work and interested in purchasing a suitable HT for portable satellite use using an Arrow antenna. Wondering what is considered to be an optimum HT especially considering ease of managing the Doppler shift during a pass. I understand that the HT must be full duplex capable and thus rules out some models.
Thanks, Gordon, NW7D
