XV144 transverter question

My transverter is set up to TX and RX on the same output connector.
Is it possible to configure so that I can retain this RX/TX as is and
have another port give me 144 mHz RX only output? I need this
capability in order to interface the transverter to my SDR-IQ SDR,
which is a receive only radio.

Re: XV144 transverter question

Hi John,

I mis-spoke. I meant to say that I want the 28 mhz receive out of the
transverter, not the 144 mhz receive, while keeping the 144 mhz RX/TX
on the single output port connector.

RE: XV144 transverter question

You would have to put a splitter in to create two RX IF paths. You would
have to set it up to use a split mode xcvr connection in order to do this
easily. However you could run with a single port xcvr if you modify the
relay schema for tx/rx switching in the control circuitry of the XV. Also
you would have to raise the output gain of the mixer output by 3dB to make
up for the splitter in Rx mode.

All in all it's very doable if you really want to.
