Who can help me with the following setup:

I trying the combination of FT-847, WISP and TNC3S to work together.

For satellite guidance I use SatPC32 (Doppler and Rotor controle)

I've connected the TNC3S via the Packet connector to the FT-847

When I try to connect for example HO-68 using WISP. I find that WISP is
trying to connect but the TNC3s isn't switching the PTT. The STA led on
the TNC3s is activated but no Push to talk is activated on the FT-847.

When I use the TNC3s without SatPC32 active on a simplex frequentie every
work fine.

Somebody any idea?

The following version and hardware are in use:

- PC P4HT 3.0 GHz and 2G memory
- Yaesu FT-847
- microHam USB Interface III
- Windows XP Professional SP3 US
- SatPC32 12.8a
- WISP (GSC V2.03, MsgMaker V2.10a, MsgView 2.00b, MSPE V2.01a, Procmail
V2.00g,Updkeps V2.00c View-Dir V2.00e)
