SO2R Operation

Can both ports be active on Antenna Genius Simultaneously?
Can both ports be active on Tuner Genius Simultaneously?

We have 2 machines (oen FLex and One Non-Flex) running FT8 on 2 seperate machines and they are on same odd interval. I understand obviously the PGXL can only accept one at a time. But what about if the TGXL was on standy ? Are both ports through on PGXL? And if one port is active on TGXL is other port on Standby / though ? Or is the signal impeded on the non TX side . Thank you

    No, The relays for SO2R are designed so that when the amp and tuner are in circuit on the A side, the B side input to output is connected directly, bypassing the amp and tuner.

    If you set up a different radio on each port, they will both receive but one will have the amp and tuner in circuit and the other will be bypassed.

    You'll only be able to transmit on one radio at a time and you will need to have proper isolation between the two radios (free space between antennas) or you can damage the receiver of one of the radios.

    Thanks for the info Dave, I have opened the SO2R board and it has a metal divider to assist in isolation. If TX on A side is routed through AMP/TUNER and B side is straight through; what would the problem be on transmitting FT8 on both ports? The FLex radio (A Side) would go through the amp and the B Side (FTDX101 with 100 watts max) would bypass PGXL and TGXL and go directly to to the AG?

    I don’t know. That would be a question for support@4o3a.com
