Hi Patrick,
That's pretty impressive, working a linear sat with an
Arrow and manual tuning. You must have 3 hands.
Hope to work you someday on the linear birds.
By the way, I'm back in Florida now after a summer in
Europe and Africa. Had about 30 FM sat QSOs in Europe
and 14 in South Africa, using an HT and an Arrow.
73, Bill NZ5N

Hi!
After months of trying to make a portable station that
would
allow me to work the SSB/CW satellites (first with an
FT-817ND
and AOR AR8200Mk2B wide-band receiver, then later with
two
FT-817NDs, all using my Arrow Antennas handheld Yagi),
I finally
made everything work. At 1756 and 1758 UTC today, I
logged my
first two satellite QSOs not using FM on either the
uplink or
downlink. As I expected, it was not an easy thing;
FO-29's 2m
uplink seemed to make it a bit easier than a 70cm
uplink like I
had tried before on VO-52 or AO-7. Now, after over
4100 satellite
QSOs in the last 2 1/2 years or so, I can say I've got
at least a
couple SSB satellite QSOs to go with the others I've
done on FM.
I know that computer control for either - or both - of
the radios
is the preferred way to go. Less work for the
operator, reducing
how much my signal moves through the passband due to
Doppler, and
simply more time to work other stations. I will most
likely end
up with a portable setup using a small laptop that can
control
these two FT-817NDs or some other radio(s),
eventually. I will
also rig up a tripod or something for the Yagi, or try
another
antenna, so I don't have to hold it while trying to
work the
radio(s). I decided that the 1745-1759 UTC FO-29 pass
this
morning to my east would probably be a good pass to
try. Good
elevation, and a footprint covering most of North
America. I set
up my radios in the back of my truck just over the
line into grid
DM44ha northeast of Phoenix AZ, and tried my luck.
It took a couple of minutes to get used to finding my
signal in
the downlink. My 5W signal with the Yagi was more
than enough.
I heard some CW early in the pass, then I could hear a
couple of
voices - Joe K3SZH and Jeff K7WIN. When those two
finished their
QSO, I quickly called K7WIN. K3SZH came back instead,
and I made
a quick QSO with Joe. I followed that up with another
quick QSO
with Jeff K7WIN. Both Joe and Jeff commented I had a
good signal
through the satellite. Thanks for the QSOs, and
especially for
dealing with my non-automated station near the end of
the pass!
Now I can go back to working on VO-52 and AO-7, plus
the new Delfi
satellite, and see if I can do the same with a non-FM
satellite
using a 70cm uplink. And keep on working FO-29, a
very nice bird.
I'm not turning my back on the FM birds, but adding
more options
when I want to play radio via satellite. :-)
73!
