Is there anybody on this list that uses HRD Satellite Tracking with a Yaesu FT-847 and HRD version v4.1 build 1989 Technology Preview II.

After working with a couple of tracking programs I am very pleased with this new software. I worked all the birds but one using HRD.

I only have one problem i can't work SO-50 the problem as far as I understand has something to do with CTCSS and the 2 second carrier with a PL tone of 74.4 to arm the timer and afterwards the 67.0 Hertz PL tone to communicate via this bird.

Sometimes I can here some audio on the downlink when I transmit on the uplink but not during the complete time that I transmit.

Can anybody give me some information that helps me solve this problem?

Thanks in advance,
