Thanks to suggestions from N8MH and WA8SME, Data jack cabling now working.
Hope to be on Falconsat-3 soon although optimal passes here are 25-29
degrees elevation.

For those interested, the IC-910H only uses the Data jacks for I/O when PTT
is asserted at the jack itself.  Input level  needs to be ~ 0.4 V p-p or
less.  Otherwise, internal limiter shuts down modulation.

Best to all,
