[ao16aprs] Re: equipment required

For the wilderness traveler, the best thing right now is a THD7 via MIR
using APRS mode.  But this is bent-pipe digi only.  SO unless someone is
in the same footprint and can respond or can forward, it is only going to
give you a 1500 km range...

OOPS, of course, if you have a laptop, then just logonto the MIR BBS as a
normal 1200 baud packet user and send and receive your traffic that way..

Ues, 19" whip for MIR, UHF yaggi for Pacsat downlink receive only
Of course, most hams have no use for such a low gain UHF yagi, but
Cushcraft and others sell them as "commercial" antennas, so ask for their
commercial listings...  Probably 4 elements would be better if you can
make it fit in your bag...

Correct.. ALl talk and no do ....

*** It did not work.  The one jumper mod forgot about the DCD for each
modem and all the switching needed to get around that.  We abandoned it.
