Feld Hell mode works well compared to other modes that tend to be
doppler-sensitive. Nino Porcino's Hellschreiber has a Satellite mode
option that lets you monitor your own signal with a full-duplex sound
See -- http://xoomer.alice.it/aporcino/
Doppler can be tricky without some kind of automation, but I've used the
Feld Hell mode successfully on everything from AO-10 to FO-29 with
manual control. Of course, there's a lot of dial tweaking with mode J
downlinks ; ).
Will look for you on the next VO-52 pass.
