[WT-support] TX inhibit with WT and EZM

[Tõnno Vähk]

I am trying to build more flexibility into PTT interlock systems for Multi Op.

 

Is there any way to abort CW or SSB message other than physically breaking the PTT lines output from EZM when using WT and EZM? 

 

For example TR LOG has TX inhibit input but WT does not I guess? EZM footswitch inputs cannot be used as it does not work this way.

 

Basically I am looking for a way to simulate pressing ESC on RUN station keyboard with TX GND signal from 2nd Transmitter. 

 

Is there such input on the LPT port of EZM? There is STOP pin but can it be used this way?

 

TX inhibit can be used on transceiver level but it is not good as it cuts off signal but the rig stays on TX. I would like to have RUN station going to RX immidiately when 2nd Station goes to TX (F key is pressed or footswitch activated)

 

Any ideas welcome.
