My two cents worth:

FM birds are only worth 1 contact per channel.  Last year, I used them
only if there was no worthwhile pass on a pass-band transponder bird
available.  The results at my club, K0GQ, had were that last year we
made more satellite contacts than in the previous 4 years combined.  We
made the most on AO-7, followed by FO-29, ISS (it was in cross-band
repeater mode), VO-52, and one contact on SO-50.  We made several
attempts on AO51 but, due to the congestion, it was impossible to make a
QSO on either channel. 

I'll put my money on the pass-band birds anytime.

Hi Mike,

Normally I would agree that the FM Sats are easier to work, and more 
contacts can be made in a short time.  But Field Day is far from a

On FD, the FM Sats are swamped with far too many people trying to make a

contact, and the single channel / FM Capture Effect generally results in

nobody getting anywhere.  As has been pointed out, any station is only 
allowed one Satellite contact, but there are so many stations trying for

that one contact that none succeed.  SSB/CW on a linear transponder is
best bet.

VO-52 is likely to be one of the more successful birds, along with FO-29
they can bring it back in time), and maybe AO-51's mode LU on the second

transponder (FM, but there are few enough stations out there with the
equipment that it might just work).  AO-07 is a crap shoot for mode, and

likely to suffer from too much uplink traffic for its severely weakened 
power system to handle.  Please go easy on the old bird.

SSB/CW can be a bit tricky, especially under the pressure of FD.  But, 
that's what it's all about - operating under less than ideal conditions,

Sounds like another option may be digital, i.e. digipeating through one
the digital birds.  Hadn't tried that before...
