Using the MFJ-1708 T/R switch?
Posted: Tue Aug 01, 2017 11:04 pm
I'm posting this to both the SDRplay Community Forum and to SDRPlay Facebook, so I apologize in advance!
My goal is to interface my TS-480 with SDRPlay RSP1 (the later for its better receiver performance). I want to use my TS-480 for transmitting while obviously receiving on the SDRPlay. I purchased the MFJ-1708 T/R switch that many of you are familiar with to do this. The question is RF isolation between the receiver and transmitter port on the MFJ switch.
Does anyone have any knowledge or experience with a setup such as this to offer an opinion about overloading the receiver input with subsequent damage to the SDRPlay? I have successfully used 5 watt QRP levels and it seems to work ok. What about 100 watts? I'm very nervous about this. My modes of operation include CW so I need somewhat fast switching.
What do you think? Are there any suggestions to accomplish this? Thanks!
