Keep in mind the uplink is 432, not 435 where the TenTecs normally are.
I suppose you could recrystal the transmitter, but not sure how well it
will tune/work 3 MHz off.
Otherwise, I usually have no problem with an Arrow and pair of 817s, or
even a whip on the downlink and UHF half of an Arrow on the uplink, and
5 watts.

Lots of users and limited resources is always ugly... whether it be
traffic, water,
groceries, black-friday sales, or working a new grid on a FM bird.
Rare grids or Field Day on a FM-bird may not be a "problem", but certainly
does
not hold us in the best light. I thought the purpose of satellite on Field
Day was to
encourage new users to the mode... would you introduce someone to ham
radio
by letting them listen to a rare dx pile-up?
An aside: is the use of QRZ? on the rare-grid side frowned upon? or would
it
make things worse? I think a lot of the errant calling is folks trying to
separate from
capture effect, or guessing when the rare one is listening. I hear this a
lot on the
ISS voice passes as well, where you can't hear the uplink of others.

Another minimalist..... :-)
Yes, you should be able to work it that way. I currently work AO-7 and
the other non-FM birds (FO-29, VO-52, and - when it was working and
in SSB - HO-68) with the following:
TX: Yaesu FT-817ND (5W)
RX: another FT-817ND or Kenwood TH-F6A (all-mode receiver in this HT)
Ant: Elk Antennas handheld 2m/70cm log periodic
I have a 10-foot length of RG58 from the antenna to a Comet diplexer,
then 3-foot lengths from each band's port on the diplexer to each radio.
I do not use preamps, although on shallow passes I will not use the HT
as my downlink receiver. The 817's receiver is more sensitive at 2m
and 70cm in SSB/CW, but HTs like the TH-F6A have receivers that are
more sensitive in FM.
In the past couple of years, I have logged several hundred QSOs in SSB,
and a handful in CW, with this portable station. I don't have a home station,
so I do all my operating with this setup from wherever I go. Other than the
antenna and anything not permitted in carry-on luggage, this station fits in
an old laptop bag, and has traveled across the US as well as to Canada
and Mexico.
Good luck, and maybe we can hook up on AO-7 or one of the other non-FM
birds. 73!
