I might suggest an Icom 821H.
I had used mine on Sats for many years and works great with SatPC32.
It is now upstares in closet. Maybe I should sell it?

At long last, the IC-9100 received FCC approval last week, so it may finally
be hitting the market. I talked to an ICOM rep at the Orlando hamfest on
Saturday, and she said they still do not have any in the USA. There are
photos on the ICOM website. Still no official word on price, but it won't
be cheap, perhaps even more than the $3000 mentioned by Jeff (I've heard
speculation close to $4000).
I have 2 FT-847s and like them, especially in Europe where I can use it on
70mhz (4 meters). Cons: only 50w out on 2 meters, problematic volume
control and power switch, no 1296 mhz option, no internal antenna tuner, no
The TS-2000 has 100w on 2 meters, a 1296 mhz option, VOX, and an HF/50 mhz
antenna tuner, but it does have the incurable birdie that inhibits reception
on AO-27 and SO-50. Kenwood apparently has no interest in providing a fix.
The IC-910 is supposedly the best VHF/UHF radio of the group, but it does
not do HF or 6 meters.
These are the only current options for a first class all-in-one setup for
linear satellites. They are similar in price on the used market, about
Many opt instead for 2 separate radios, such as a pair of IC-7000s, FT-817s,
FT-857, FT-897, FT-706 MKII, or a combo of any of these. This is
particularly attractive if you already have an all mode rig for 2 meters.
The cheapest route may be a pair of FT-817s, if you can live with the small
knobs and controls and the 5w out (adequate for the sats with a good
antenna, and if you want more you can buy a cheap 30w amp). You can buy
these used for under $400 each (the newer ND model is pricier).
Software such as SatPC32 or Ham Radio Deluxe controls the 2 radios so that
the downlink frequency matches your uplink. Stay away from the older radios
that cannot be computer controlled.
It is theoretically possible to work the linear sats with a single,
non-duplex radio. As the tracking programs are supposed to set transmit
frequency automatically to match the spot where your receiver is tuned, it
should not be necessary to hear your downlink. I made a few contacts this
way with a single IC-7000, but it is not recommended, as the tracking
programs are often a bit off with the frequency calculation.
There are also some intriguing transverter options but I'm not familiar with
those. If interested, check out the Elecraft, Down East Microwave, and Flex
