You can select which transmitter to use the MOX associated with the RX2,

Alternatively, if you are using E-Coder or E-Coder2 to key the PTT, you can select which transceiver you would like to key from the Options->Panel tab:-

Basically, each radio has it's own PTT line and you select the radio to transmit on by the PTT that you use.

thank you for your detailed reply. i think i was looking past the obvious. also interesting about the ptt line comment. now i have set up ptt line in com port settings for both receivers and now can use for example wsjt on 2 bands and easily jump the tx. ime using sdc macros for cw (pileup) keying and on a closer look there is a option to chose between rx1 and rx2. so all is well many thanks
