Re: BEST satellite radio?



I use the IC 821H and it works just fine.  I had an FT736R and it did the
job also but would have required modification for 9600 baud packsats.  The
Icom is a bit more user friendly in my opinion but does not allow a 1.2 ghz
module.  I would plan to use converters at the antenna for that anyway.  The
Icom is now discontinued, but still available.  Really, the radio is
probably of lesser importance.  Antennas, transmission lines etc. come
first.

Again, for P3D.  For frequencies above 440, the consensus seems to be toward
antenna mounted converters.

As to power - P3D requirements should be minimal.  I work most of the
present birds usually with no more than 1 to 5 watts.  It's in the antenna
system.  I do boost it up for AO-10.  This is why you see little comment on
power requirements.
