    External RX/TX Switch for use with a L144-28 Downeast Transvertor Question

    Member ✭✭
    edited April 2022 in Peripherals & Station Integration

    I just picked up a used L144-28 Transverter which is configured for separate RX and TX. I would like to keep it in that configuration as I WILL be looking at using separate antennas down the road.

    Can anyone suggest a good quality RX/TX Relay that I can use in the mean time? I've seen the MFJ-1708B-SDR-S and it looks like it will do what I want - but suggestions for something a little more substantial with regards quality/construction? Or am I being too picky?

    Or would this be suitable? Tohtsu CX-600N SPDT N

      Hi Richard, what radio are you using it with? You might not need a relay at all.

      How did I leave that off!? Yes - useful information.

      Flex 6500 Signature Edition.

      I just realized that I read your original post as split IF as opposed to split RF...

      Yes, the relay you show should work well. If you change your mind and decide that you want to stay with one antenna, you can order the relay from Q5 and install it on the transverter board yourself.

      This is a 2016 unit, so it has the K3 relay already installed.

      I think I will order the Tohtsu - what have I got to lose apart from $120 :-)
