Thanks, Drew. I didn't realize AO-27's status, and I wasn't really looking
forward to getting up in the middle of the night anyway :-) (although SO-50
has an excellent pass around 330 am :-) )

I did play around with AO-27 and SO-50 most of the day Wednesday, but yeah,
I haven't really been active on the sats since a 1993 AO-13 DXpedition to

The reason I'm planning on using the HT and Arrow is to show them the
(nearly) minimum equipment that can be used to work a sat - that they don't
have to have a fancy radio (IC 910, IC-9100, TS-2000) and a big antenna
array to work the birds. (I do have switchable CP yagis on 2M and 440 at
home, with an az/el rotor, but transporting all that would be too much
logistically AND I thought it would be overkill and too intimidating for an
audience whom you're trying to attract into ham radio.) But yeah, I'd much
rather have full-duplex like I did on AO-13.
