I don't believe that either the K2 or the Icom IC-7000 are suitable for
satellite use. For optimum performance and minumum frustration, you really
need full-duplex, cross band capability. You must be able to transmit on one
band, while simultaneously receiving on another band. I don't think the
IC-7000 supports this mode. Be sure before you decide.
(I use an ICOM IC-970 for this. Could be portable, if I put wheels on it...)

[Bit of a ramble]
I am currently wondering exactly what to do on the K2 front - I may buy the
IC-7000 because it has 2m and 70cms and can be taken out portable (with a
decent battery), also some of my portable locations have 220 volts available
and there are some very small switch-mode power supplies available. The
IC-7000 would solve quite a few problems in one easy-to-shift package - want
to get out on 2m, 70cms as well as HF.
Not being able to adjust the K2 TX frequency via CAT control makes the K2 +
transverter option unrealistic for satellite use, this would have been my
main use for the K2. The IC-7000 can be adjusted while in transmit.
The IC-7000 downside is RX current drain (1.2A), but solar cells can
compensate for this. Cost-wise it's much cheaper than the K2 + options +
transverters, but obviously the K2 is a different beast. And I have the KX-1
/ K1 / T1 combination anyway.
On the satellite side I am really waiting for the P3E satellite and may
stick to the 1.3 / 2.4 (and higher) GHz side of things anyway as I'm sure
the 2m / 70cms transponder will be pretty full.
What I think will happen is that I'll become familiar with the K1 first,
then try a side-by-side comparison with the K2 while out portable. I see the
K2 purchase being put back a year or maybe two - we'll just have to see.
Maybe a visit to FDIM in 2006 is needed to help make the decision - if
finances and US passport requirements permit.
