When you step back and look at the state of the satellite transceiver
market, it's not all that different from the 1990s. The difference is that
Yaesu doesn't produce one, otherwise each of the "Big 3" have only produced
one model at a time. The other difference is that both the Icom IC-9100 and
Kenwood TS-2000 are "shacks-in-a-box" which increases costs for those who
already have or don't want HF capability. The TS-2000 is also lacking
because of its birdie on the SO-50 downlink frequency which prevents me
from ever recommending it.
The other downside is that both of those options are not exactly "field
friendly." The Icom IC-820H, 821H, 910H, and Yaesu FT-847 are all small
enough to be used in the field. Many have remarked that the Icom IC-910 and
an Arrow antenna is the simplest and best performing portable satellite
station available. These transceivers are not to difficult to find on the
used market, but the prices can be a bit high owing to continued demand.
If you want to buy new equipment for the field, Norm's suggestion of two
Yaesus is not a bad one. Dual FT-817s are very commonly used. NJ7H has used
his "FT-1634" to activate 250 grids and 7 DXCCs on satellite over the past
year. I use a "FT-1634" plus a small dual band amplifier (a Microset
VUR-30) and preamps for a well performing portable setup. Others have used
the "FT-1674" (a Yaesu FT-817 and FT-857 combo) with great results. The
downside is that you often need filtering to eliminate desense between the
two radios. A common diplexer such as those made by MFJ or Comet works for
this purpose.
As suggested, the future lies in the SDR realm. At the present time, these
solutions are not ideal for the field. Many have used SDRs such as a
FUNcube Dongle or SDRPlay as their downlink receiver paired with an
all-mode transceiver for the uplink. Properly configured, this can work
very well, but use in the field can be difficult due to glare on laptop or
tablet screens. Many have used this type of setup with great results in
home stations. Another downside is SDR processing delay and its
difficulties with full-duplex operation, but this can be mitigated with
more efficient programming and/or more processing power.
When it comes to a full SDR transceiver setup, as Norm suggests, this is
doable today. While Flex no longers offers the Flex 5000 and V/U modules,
there are other options that could work quite well. The downside is that it
is not "plug and play" at the moment, you need to add filtering and
amplification to the available SDRs. I don't think any user friendly
software exists at the moment either, but there is definitely an
opportunity there.
The AMSAT Ground Terminal team is working on a full SDR based ground
terminal for use with digital 5 GHz uplinks and 10 GHz downlinks, to be
used with a number of future AMSAT satellite projects/payloads in GEO, HEO,
and beyond.
When you consider all the options, there are likely more options for
getting on the satellites today than have existed in the past. There might
not be as many plug and play boxes available from major manufacturers, but
there are lots of ways to build a ground station for home or field use, and
ways to do that to meet almost any budget.

Talk to the guys at Flex :)
They are participating in the Phase 4 ground station work and they know who
we are.
Then again, they know who we are (grin)

Yup, had one here for a month now. Paper written for the Eastern VHF/UHF
Conference coming in April - plus a Presentation on the LimeSDR on
VHF/Microwave.
Bottom line - for satellite use, possibilities, but not ready yet.

I have a pair of old Landwehr RF switched receive pre-amps (one 2m and one

service about seven years ago, but they have been sitting around a long time
and I have no means of testing them at the moment. Strictly "as is." They
*DO* have the rare power/control cable connectors with them.
Contact me off list if you are interested in making a deal on these.

*DO* have the rare power/control cable connectors with them.

Hi all,
I have some time, so heading over to EM85 to catch the SO-50 pass at 2114z
to fulfill a request. The pass doesn't cover the west coast, sorry; might
try a pass favoring that side of the country another day. Could be some
other activity on from the Gulf of Mexico or the Yucatan, so patience as
always will be key. I'll do my best to work everyone that needs the grid,
but we all know how it can go.
73 and see you on the birds,

Looks like my TS-2000 needs to go back to HRO for warranty service. I have
no problem on FO-29 with the 2 meter uplink and 70cm downlink, but reversed
for other sats I get a cw message ?(UL) PLL Unlock and rig goes dead with
dashes on screen. After turning the rig off and on again it comes back to
life. But as soon as I transmit on 435mhz again, it cuts out. No problem
transmitting on 2 meter uplink. Anyone else experience that with their TS2000?

This is a common fault with the TS-2000.
