Thanks to all who replied! We are in fact using a Verizon EV-DO card, so
the bandwidth information is much appreciated. Thanks again!

Gudday
I did some tests
10.8 Volts = 500mA = 4.21 Watts out
11.8 Volts = 600mA = 5.09 Watts out

As soon as it's Posted.... I'll start tinkering around with it locally.
(Jacksonville FL) I would like to see 10M FM; specifically; 29.1MHz area,
opened up for 1200BPS Packet. If they can SPRAY our Spectrum with
RADIATION, why can't WE open that spec of band for Packet...???!!
(I used it quite a bit in J-Pan; it was even PL'ed, so you don't have to
listen to any locally produced NOISE of any type)
Why not do some Lobbying of our OWN, instead of letting the $$ Makers take
over EVERYWHERE ?

Political issues aside, wouldn't you have some problems with inter-symbol
interference? If you're going to chew up big chunks of spectrum, COFDM
would seem like a more practical way to do it.

The issue I have with multiple frequencies is finding out what the freq is
when travelling through the area of coverage. You'll need yet another call
book or some document listing the freqs. If you're a regular traveler
you'll likely not use the UHF side because it's too hard to keep track of
all the freqs. The nice thing about the common freq 144.39 on VHF is I can
hop in the car, set the tracker up, and go, and not have to change anything
along the way. One option that will help that, and I think we should start
doing this in the Puget Sound area, is to announce on the 144.39 freq the
availability of UHF APRS on 440.875. I will adjust my beacon here in Spokane.
If 440.875 is available in your area, use it. If not, pick another freq
where APRS/packet falls into your band plan. Tell the rest of us so we can
update a web page and local listings.
I don't believe we'll ever settle on one UHF freq for APRS. It would be
more important to not delay the UHF growth, pick a freq and go with it, and
announce to the world via BLN or ANN and web page listing the UHF info.
I would like to see all the big metro cities (you know where they are) to
put up a UHF APRS digi and capability to uplink to the APRS-IS via an
iGate.
Since this post is new to the aprssig, you can get more info on the NWAPRS
exploits of UHF APRS on our website: http://www.nwaprs.info and check the
table of contents.
