Jim and any others interested:
http://www.amsat.org/?p=1489 An article written in 1994 on the principle I was alluding to. Way-back in 1999, AA2TX wrote Instatune which performed this for the FT-847. KB5MU writes in 1999 that several other programs have this feature (but the link is broken to the Amsat Store). Currently Amsat offers: MacDoppler and SatPC32 (which I already have). http://store.amsat.org/catalog/index.php?cPath=2 I'll have to check to see if it is implemented in SatPC32 (what radios are supported). But most likely it does not support control of either the K3 or KX3. Software mavens most likely can easily make a driver that will work with SatPC32. 73, Ed - KL7uW From: Jim Rogers <[hidden email]> To: Edward R Cole <[hidden email]>, [hidden email] Subject: Re: [Elecraft] Fwd: Re: Full duplex for Sat work?
