Re: help with 817 and satpc32



Hi Tim,
here the program seems to work flawlessly with my FT-817.
I tuned VFO A and B manually to  50.000 MHz  and set the mode to AM  (both
VFOs).   Then I started SatPC32 with CAT steering activated at start (menu
Options). My first satellite is FO-29. The program  switched the radio into
Split mode and tuned both VFOs to the correct frequencies and modes
(downlink: VFO B,  UHF, USB,  uplink: VFO A, VHF, LSB). When I pressed the
PTT button the radio transmitted on the correct VHF uplink in LSB and  I
could tune around in the passband with the VFO.

I made the same test but with CAT steering deactivated at program start.
When I activated CAT steering (C+) the program did all settings correctly,
except the uplink mode. This was USB instead of LSB.   I clicked the FO-29
ident letter and the uplink mode was then also set correctly to LSB.

My settings in menu Radio Setup: CAT baud rate 38400, CAT delay 110. All 4
checkboxes unchecked. Interval in menu CAT: 70 Hz for SSB, 200 Hz for FM
sats.

73s and Happy New Year,
Erich, DK1TB
