The FT736R is not known for having much dynamic range. I own one. :-)
Its a great overall rig for VHF/UHF use with multiple bands in one box,
but as a result there are many compromises. Most multi-band VHF rigs
compromise their dynamic range, phase noise etc.
In general a high performance transverter, like our XV family, paired
with a high dynamic range rig like our K3 and K2, will outperform most
multi band VHF/UHF rigs for receive performance.
The Elecraft XVs are designed to match the wide dynamic range of the K2
and K3. Plus their front end pre-amps are very quiet. While they will
work with most HF rigs, they tightly integrate with the K3 and K2. The
K3 supports up to 9 transverter bands (6 on the K2) with correct VHF/UHF
frequency display and individual transverter offsets programmable on
each band. Each of our XVs will power up and drop on/off line as they
are selected by the K3 or K2. Also, we support using an XV, like the
XV144, as an intermediate IF for microwave use.

Tom,
My background is physics, not rf theory. But you're saying that the xv144
gives you better performance than a rig that was designed for that? I guess
thats not too hard to believe, but still counterintuitive from my
standpoint. Do you think I would get acceptable results from adding a texas
microwave (or any brand) on top of the xv144 for 1.2 (or is it 1.4) ghz
operation? My main interest in this area are the amsats but I've only
managed a few sketchy qso's with a handheld before. Using transverters is
uncharted waters for me. The only reason I'm considering one now is that 1.
elecraft makes them and 2. a lot of folks seem to use them... so they cant
be that bad right? I'm just skeptical of the added noise you introduce into
the system with using them. Again though, I have no practical experience.
