The good news is that it is easier to see one's self on GO32
than on the ECHO satellite, because GO32 has a PTT delay some of
the time.  So your radio will have turned around in time to hear
your packet come back...  But if you are in the mobile, you
probably get a good downlink for the center 3 minutes of a good
high pass.

But you can get in from horizon to hrizon if you are running 50
watts.  That is why we need LOTS of people Igating the downlink.

The best way to do this is to encourage all D7 owners that do
not use their D7 routinely, to not just set it in the closet,
but leave it hooked to your Igate all the time you are not using
it.  Connect this through a SHORT colx to a 19" vertical whip.

This station will receive GO-32 downlink packets for the center
3 minutes of the best two passess per day... And if we have
enough people doing this (say a dozen over the USA), then at
least one of them will always have a good chance of hearing each
packet and feeding the APRS-IS...

And since coax loss is the big bugga... The better way is to ptu
the D7 up near the antenna and run only the 3 wire RS-232 down
to the shack...  Then you don't need a pre-amp...
