I'm the guy with the Elecraft XV-50 and the Omni V on 6 meters. My Omni
V has the N4PY chip kit in it, and it has the factory QRP power
reduction mod, too.
The XV-50 is the only one of those transverters with a way of setting
the LO on frequency. The others are set up with a K2 in mind, where you
program the radio to the proper frequency correction/offset.
I have my transverter set up with separate transmit and receive ports,
and I use the auxiliary receive port on the Omni V to connect to the
receiver IF output port of the transverter. I drive the transmit side
with only a few watts. I also run the transverter with my Argonaut II
QRP rig, and it works very well with that rig, too. The Omni V has 0DBm
transverter capabilities, but I had no luck getting them to work with
the transverter. The transverter would start to oscillate and the power
output was enough to blow out the final transistors in my ancient Mirage
6 meter brick. I corresponded with Elecraft tech support, and they
basically recommended that I jumper the transverter to work with greater
IF drive. They also gave me some advice on how to trim the heat sink
insulator to just the right size for the power amplifier module, and a
different way to wire the SO-239 RF connector in order to make the
transverter more stable and reduce the transmit flying problems.
I set the receiver front end of the transverter with an Elecraft noise
generator, and it works very well. I have not measured the noise
figure. I have found that the Omni-XV-50 combination works very well
once I got the transverter stabilized. I believe that you can drive it
with up to about 8 watts without problems. It has overdrive protection.
I use the Omni's amplifier T/R relay contacts to key the transverter,
which then keys the Mirage brick.
It works very well, overall. The Argonaut II has a better noise
blanker, but the Omni receiver has better bandspread and selectivity.
For CW I like to use the 500 Hz filter in the NAR slot, and I have the
auxiliary 1.8 KHz, the 500 HZ, and 250 Hz optional filters in it, too.
I have worked a bunch of DX with the combination, and it has been
dependable once I worked out the bugs. I would think that an Omni VI
would also do an excellent job with the Elecraft transverter.

This past week someone posted a note and mentioned they were using a
Elecraft XV50 6M Transverter with their OMNI 6 (I think). Anyways I have
lost the message, I have some questions regarding the hook up of the
transverter. Does the transverter use low power to drive it? i.e. 1W?
Better yet, what I am up to is adding 6 meter coverage to my OMNI VI. Any
suggestions?
