Transmit-receive switches
Posted: Mon Jan 14, 2019 8:44 pm
The adjacent thread "MFJ-1708B-T/R Switch Experiences" reminded me of a question I wanted to ask, but I thought it might be clearest to post a new thread rather than tag on to that one.
Currently I have two SDRplay RSPduo units running continuously, each attached to its own magnetic loop antenna. I'd like to set up a T/R switch arrangement so that both RSPduo's are disconnected from their antennas when I transmit via my Icom IC-7300 (which has its own separate antenna).
One way to do this would be to obtain two MFJ-170B T/R switches, and connect each to one of the RSPduo's. Hopefully the IC-7300's PTT send-control signal out won't have any problem triggering both switches.
Before I proceed with this, does anyone have any suggestions for other ways to accomplish this? Are there any commercial T/R switches out there that can handle two antennas that connect to two separate receivers at the same time?
