    John, thanks for posting. Some great options there. I want one of those Monitor Sensors transverters.

    What's your antenna setup?

    I checked out a couple of lowfer transverters from down under. 10 W output. and they cost more than my 160-10M 100 W transceiver !!!

    The antenna here is my 80m dipole fed as a T-top vertical against two radials and my cold water plumbing. The feedline (vertical section is 90 feet) and the horizontal is 135 feet. It seems to work well transmitting but is very poor as a rx antenna. Unfortunately, using the Monitor Sensors transverter (or any xvtr) forces one to use the same antenna for tx as for rx.

    VK3XDK used to offer a transverter board (supply your own enclosure) that had dedicated TX and RX antenna ports. I use a pair of them, one stripped of the TX parts, to feed both receivers in my K3.

    NO3M & K6CLS: Interesting options - I'll look into them, thanks.

    I think the VK3XDK transverter boards are no longer available though. I couldn't even get his site to come up last time I checked.

    Why? Why is it not possible to install a Tx/Rx relay between the radio and transverter or Ultimate 3S amp for those who don't have dual port radios?

    MFJ and Array Solutions sell off the shelf relays, and there are dozens of plans for cheap homebrew relays.

    If you open up the IC-7300 (2 diodes removed), it will transmit about 30-35 watts on 630m.
