I enjoy some of the features on the SG Lab transverters. You can set
jumpers to switch the LO, and output in a different part of the band
(moving from the sideband portion of 33cm to the FM portion, for instance).
It's easy to get either dedicated RX port or a split TX/RX port. 10MHz ref
is optional but as a dedicated port. Can be switched via RF or PTT (this is
debatable, since you're hot switching relays in this case I think).
The DEMI 3cm transverter I have has a nice relay feature, you can hook up a
24VDC relay as a T/R relay and drive the transverter with 12VDC, it'll fire
a cap to give the relay enough juice to switch even with only 12V in.
