When AO-51 failed late last November, I figured that usage of the other
two satellites would increase. That has certainly happened. Crowds
are up, and more new stations are showing up to try them out. Many
who saw AMSAT's demonstration station at Dayton took the time and
effort to try making their first satellite QSOs, and it has been fun to
work some of those who I talked with at Dayton. :-)

As much as some speak ill about grid expeditions and stations trying
to make a very short QSO, that does help kick up the levels of activity.
These days, you'll hear this activity on SSB as well as FM. Not a bad
thing. I haven't done a lot of road trips in the past few months, but I am
looking to do more of that as the summer comes to an end here in

Agreed! The new stations are making their ways onto the satellites,
as that MP3 file KK5DO made and referenced in another post this
evening with N5AFV's comments.

And you can see examples of my operating from home and some
other locations in a few videos at: http://www.youtube.com/va7ewk
I have never had a home satellite station. For most of the time I have
been working the satellites, I have either lived in an apartment that was
not a good place to set up antennas inside or out, or a house in an
area covered by strict deed restrictions and a rental agreement that
don't let me set up antennas. Initially with the FM birds, and now in
SSB and occasionally CW.
I am now giving some thought to setting up a temporary antenna
array in the back yard. Last year, I went to San Diego to give a
presentation to a radio club out there on satellite operating. I saw
the station John W9EN uses at his house. His 2m and 70cm
antennas, along with an az-el rotator, can be quickly set up in his
yard, then the cables connect to the outside of his house to go to
his station inside. When he's done, he can take the antenna array
down. Very impressive!
If we had HEO satellites now, I would make changes to my station.
The FT-817s could still work, but I would consider a radio with more
transmit power for the uplink. An FT-817 could still do well as a
receiver, or with possibly a preamp connected to it. My handheld
Elk log-periodic antenna would be swapped out for larger antennas
with more gain. Until then, I'm having fun with the satellites we
currently have - whether I'm at home, or on the road.
My satellite log has over 11,000 QSOs in almost 7 years' time,
with all but a couple dozen of those made with portable equipment
set up wherever I happened to be - in 14 different US states and 3
other countries. With hamfests coming up in the fall, along with
the AMSAT Symposium in late October, I'm looking forward to
being on the satellites from more different locations. And some
new ones (I've never operated from Florida, and haven't been to
that state other than to change planes in Miami since the mid-
