Sorry the list of rigs should read FT847 not FT897D
sorry about that

Good Morning John
I use a FT897D for satellite and also a FT817 for Full Duplex operation
I use them together so I can hear myself on the downlink (which is the
proper way to do it).
It receives the satellite fine(both rigs)but I would not consider the
Ft897D
a upgrade or vise versa,the best upgrade to do as a first thing is the
antenna and cable and quality connectors.The draw back that I don't like
on
the Yaesu rigs is that the cat system cannot work during transmit,so
Doppler
is not corrected when you transmit and can be a bit of a pain when trying
to
setup your software for calibration.Its not to big of a deal and you can
work around it.I personal believe that upgrading to any one of the multi
band and multi mode rigs wont show any improvement.I have learnt allot
from
this board over this year and I live buy this rule (High Gain Low
Loss).If
I had an Icom and I wanted to buy another rig to run full duplex,I would
buy
a Icom,just for the fact that I mentioned above about Doppler correction
and
calibration.In order to upgrade your transceiver it is best to buy a rig
that is design for satellite operation (IC910H,TS2000,FT897D,FT736R,etc)
this is just my personal opinion.
Good Luck

Is anyone on the list using a Yaesu FT897 or FT857 on the LEO satellites
(both FM and SSB)? I am currently using an Icom 706MKIIG with pretty
good
results, but have been thinking about upgrading to a Yaesu FT897D or
maybe a FT857D. I have used some Yaesu rigs on the sats before and the
706MKIIG seems to hear them better, especially AO27.
I don't have a big setup-Cushcraft dualband yagi (5 elements on each
band)
with no elevation, so signals are not rockcrushing from the satellites.
The QST reviews show that the Icom has better sensitivity on 70cm SSB
(MDS
of -143 vs -139 dbm) and on FM (.16 vs .21 microvolts) but are those
differences really meaningful? Do the 897 and 857 still receive the sats
really good with a minimal setup?
