Hi Jan,
does CAT control work correctly if you connect the FT-847 to the physical
COM 1, particularly with  SSB sats (FO-29, VO-52, AO-07)?  The program reads
the RX VFO frequency once per second to allow transparent tuning (that means
you can tune the radio with the VFO knob).
I suppose your FT-847 is not one of the first on the market? These
first radios didn't allow to read the VFO.
Is there a difference between SSB sats and FM sats?

CAT control of the FT-847 works flawlessly for many years
already. I use it with physical ports (built in and via PCI card) and with
my 4-Port Keyspan USB-to-serial adapter and it works also with a Prolific
and FTDI single port USB-to-serial adapter under Windows XP, Vista and
Windows 7, 32- and 64-bit.

My settings in menu "Radio Setup": CAT baudrate 57600 (at the radio menu
37), CAT delay 20, option "Satellite mode" checked, other options unchecked.

My previous mail to you was bounced by the mail delivery system. So, I send 
it also

73s, Erich, DK1TB
