I have purchased this switch:? Antenna Sharer, SDR Transceiver...
?
It is powered by 12v and uses a ground signal to close the relays and disconnect the SDR while the radio is transmitting to avoid overloading the SDR. I've tried a few configurations with no luck. I'm currently using a digirig for cat control and audio pass through.
?
I've tried using pin 2 and three of the cat cable but the radio doesn't send ground when transmitting.?
?
I've seen the mfj used to make a cable that went into the radio and broke out of connection to activate their switch. Does anyone know how that works or does anyone have any ideas as to how to get this working??
?
This is the MFJ cable?
?
I have used a splitter to split the 8-pin cable so I have a breakout. I just don't know what pins they would have used. I can solder the wire to the 3.5 mm connector for my switch. I just need some ideas as to how to proceed.?
?
?
Thanks in advance for all the help?
