My set-up:

Windows 10 & SATPC32: works perfect with TS2000 (CAT delay 20)

Now I want to connect my FT817: via a Bluetooth Dongle.
Pairing to the PC successful.

Now letting SATPC32 control the FT817:

- started with CAT delay 20: works kind off, downlink (RX VFO A): OK,
uplink (TX/VFO B): frequency not correct

- increased CAT delay (5, 10, 20, 30, 50, 60, ....110): effects start
to vary but never OK
   + at some delays flipping between VFO A and B without pressing PTT
   + freq of VFO A and B continue to be wrong 
   + often in RX VFO B is selected, pressing PTT VFO B (should be the
other way around) 

Tried at CAT rates 9600 and 38400, no differences.

Seems like a timing problem to me, as there is influence of the CAT
delay setting.

Official recommendation: CAT RATE 38400, CAT delay 110. (that does not
work though)

A friend has similar problem, when using a wired USB interface between
PC and FT-817.

Who has some tips for us ?
