SK2HG TB7100 Modem Settings

The TB7100 has DSPs in both the TX and RX path so the signals are delayed.

Before struggeling with the RX path I decide to open the Squelch as the Audio output was squelched. It had to be done with the Tait calibration program (TB71_CAL) not with the normal CPS program (TB71_XPA), by setting a low value for squelch opening, I think I put -136 dBm there.
