Hello John,

 My mods to FT-726 is as follow.

1. RX data connection
 RX signal is drawed from the junction R44-DO4(1S188) with 10K ohm resistor.
 It must be connected to RX in of G3RUH modem

2. TX data injection
 You must inject both TX unit and Satellite unit if you need full duplex
 operation ( example for uosat4/5 ).
 The TX data injection point is  DO5(FC-53)-C27 in TX unit and
 DO6(Fc-53)-C25 in SAT unit. You may be able to direct connect from
 TXD out of G3RUH modem as DC decoupling is in the modem board.

3. You need selection SW for TXD injection to select sinplex/full duplex
 operation.

73s.   sueo  @ uo-14, ao-16, lo-19, FO-20
