I use an Elecraft XV-222 transverter for 222 MHz. It has a very good
receiver as it is sensitive and very immune to overload and strong
signal intermod.
Having said that, it has a couple of faults.
The first is that it runs hot and although 20 Watts out can be run on
SSB, it will still run hot, and the power should be probably be held
to 10 Watts or so on high duty cycle modes like FM and WSJT. This is
not a problem if you have a linear that takes the lower power input.
The second is that my unit drifts noticeably from a cold start. While
probably not a problem for fixed station use, where the power can be
left on, in the rover I turn it on only when I go to 222 MHz to
conserve power and then it drifts as it never gets warmed up as I am
turning it on and off.
With the K2 it has a nice interface and is if you are using a VHF
transceiver. - Duffey
