[WT-support] TX inhibit with WT and EZM

[I4UFH HRS]

Hi Tonno,

Take a look to these programmable Footswitch, u can use one of them in parallel to the Multiplier footswitch so it can send an ESC to the RUN PC. If u use EZMaster and WT in this way u can stop, Fxx messages, but not foot pressing, even EZMaster can be programmed to stop PTT out also from software with the footswitch pressed, WT doesn't support it, ESC stops omly Fxx playing, so i can still suggest to use this footESC AND brake PTT lines, both action solve ur problems in all modes.

  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.
