[Elecraft] XV144 transverter question

[Gregg R. Lengling]

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.

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.
