It's certainly the case that many people operate "out in the field" and do
not have a computer available.
My radios are not computer controlled, even in the shack.

Certainly desirable Tom, but I've been in Amsat and on the birds since the
'70s and it wasn't until the last couple of years that I got my PC hooked
to my FT-736R! And then just this year to get it hooked to my FT-817 (IF)
radio.
I will say that there's nothing better than PC doppler and rotator
control, having used 3 hands many times in the past. I would be a
terrible drummer! But for all fairness, there are a number of reasons
that one may not have PC aided doppler correction so the one true rule
still holds good.
Not a flame, just another opinion. I'm sure this thread will get some
mileage!

I always varied the transmit.
This way the person I'm talking to as well as any other listeners are
all on the same freq listening.
Growing up on the birds when you had to twist the BIG knob to keep
everyone on freq is not not a big deal. And to this day i still don't
know why it seems to be a problem now days.
It all just takes practice. just like in field day coming up our club
tries to get the non HF users to come out and try it. and at times it's
incredibly painful to watch the guy that operates "Channelized" radios.
IE: 2 meter FM
How it will take them minutes to finally be within 500Hz of being on
freq of a ssb signal. And even then most of the time they will be
calling someone when it's obvious they are no where near on freq. then
it's twiddling the big knob again going right past on freq spot and
again try again off freq. Where a seasoned operator will tune them in
in 1/2 a sec coming in from one side and stop dead on freq.
it all just takes time on the air.
simple.

OK my brain may be playing tricks, but if you vary only your transmit
frequency such that you always hear yourself on the same downlink
frequency, isn't it true that the other station may not necessarily be
hearing you on the same downlink frequency and is chasing you anyway?
Your doppler is +5kHz (for example) on the receive, the bird is just about
to pass overhead of me though so my receive ferquency goes rapidly from
+2kHz to -5kHz, your transmit tuning has no relation at all to what
frequency I am listening on. Then the bird goes past you and you suddenly
switch down 5kHz, so I have to follow you on my receive.
Or am I nuts? (Quite possible, come see where I work and you will
understand!)

Ok, Smartphone,
Me Bad, I thought this was just another group using a cellphone on a
balloon flight. Upon further reading I see they did take the data out of
the "Phone" and downlink it via "Ham Radio" Who's call I wonder?

doppler effects both paths, up and down.
so at least if everyone is listening to a 100Hz freq tone at 100 Hz, we
are all on the same freq.

Has anyone had success getting into VO52 using a vertical, omnidirectional
antenna on the uplink. I have a nice M2 2M9SSB for 2m but only have a
dualband J pole to cover UHF with and wonder if I could get into VO52 with
it for my uplink antenna.

The 4kg nanosatellite STRaND-1 developed in the UK by University of Surrey
and Surrey Satellite Technology Limited (SSTL) will be flying a Smartphone,
see
http://www.southgatearc.org/news/january2011/mobile_phone_in_orbit.htm
I recall they were hoping to launch by the end of the year.
The great thing about flying Smartphones is you get loads of Processing
Power, a Still/Video Camera and GPS in a very small and very cheap board.

At about the 17.5 minute portion of the current Ham Nation podcast (episode
THREE already!), Bob Heil "teases" the audience about our upcoming show
dedicated to working the amateur satellites! We're shooting for a Tuesday in
July date - stay tuned!

I have had some success with vertical monobanders on all of the birds
including VO-52 and A0-7. I use a Ringo Ranger II on two meters and a
1/4 wave homebrew two meter groundplane for 70cm, which makes it 3 waves
long for 70cm. The main disadvantage I run into is that two different
antennas located at different locations on the house here cause
dissimilar tracking of the birds.
Remember, a vertical antenna with gain will cause your angle of
radiation to be lower than a simple 1/4 wave for that particular
frequency. I find that with the Ringo my best angle is about 15 - 50
degrees. The 1/4 wave 2 meter used on 70 cm is a bit better. It is
difficult to work AO-7 with this arrangement but is doable.
Some day I'll get my arrays back in the air (down since the storms of '04').
