I have made a few QSOs on the SSB birds while running half-duplex. Now, I am trying to implement full duplex using an FT-817, an FT-897 and an Arrow antenna on an az-el rotator. Separate coax cables connect the FT-897 to the 70 cm part of the Arrow and the FT-817 to the 2m part. I have a diagram of this setup that I could post.
On the 1215Z pass of AO-07 just now, I was able to hear my CW signal while sending a string of dits. I set the FT-817 to 145950 CW mode with no Doppler correction and listened via headphones. On the FT-897, I started transmitting at 432150 CW with no Doppler correction. Eventually my transmit frequency reached 432146.1 and I heard my dits on the FT-817. Then I entered 3900 as the Upl Calibr in the CAT menu of SatPC32. I switched the FT-817 to USB mode and the FT-897 to LSB and clicked on the Doppler correction (the C+) in SatPC32. Using a handheld mic on the FT-897, I called a short CQ, but did not hear my voice. I have the FT-817 as the top radio in the Radio Setup menu of SatPC32 and the FT-897 as the bottom radio. With all of these settings, there is ample opportunity for error! Can anyone offer any suggestions to get me straightened out here? Thanks in advance for any assistance.
