I'm going to suggest getting in touch with the EMA group for the
university. Sometimes they have heard of ham radio, and will support
efforts by paying for "expensive items", knowing that a ham radio
station can and will help them in the event of an emergency. However, I
can understand hesitance to want to work with them. It's just another
form of buy-in that may be leveraged at the university to sustain the
club's communications capabilities. Fiber optic to the middle of a
field? If EMA is behind it, it can happen. "That? We need that. It's our
fall-back to the fall-back." They might also be able to find or locate a
site which is similar that has better connectivity (fiber) and an
emergency generator.
FWIW, the TS-2000B isn't a bad radio, rather capable, but the software
is Windows 2000 vintage. West Mountain Radio's Rig-Runner Plug-n-Play
has a built-in sound card, and there's an accessory to connect to the
Radio's CAT port. That and Skype, Ventrillio, SIP, IAX, etc., can be
used to get audio to and from the radio. My preference is toward
one-to-many sort of audio management on the receive-side, so that
multiple listeners can easily connect. One should expect that the
trustee monitors the use of the club station....
I do hear that Kenwood is coming out with another radio like it "soon".
The important thing to remember about WiFi is that there's a LOT of
spectrum available on the 802.11A (5GHz) band versus the 802.11b/g/n
band. With a pair of 23dBi dishes over a seven-mile-or-less shot, a pair
of 32mW radio cards will do the job. A 23dBi dish at 2.4GHz is a
two-foot by three-foot parabolic dish. At 5GHz, the antenna has more
gain, but it'll be a different antenna. 2.4GHz is usually close enough
that the grids are the same between 2.3-2.5GHz, so MMDS and other
antennas are frequently used.
It's also a good idea to look into any way that a site can be shared,
but I will offer this caveat: While guyed towers are cheaper,
self-supporting towers don't tend to fall over when the non-existent guy
wires are struck by mowers, trucks, tractors, etc.
What you don't want is a site where you don't have exclusive access to a
given space, and there's telecom gear in the shed with you that's
unshielded. A site like a field in the middle of nowhere is great, but
if it comes with stipulations like it's shared with EMA, without
exclusive access to the ham side of things... then it's less than idea.
Ideally, you start with a tower, and then start hanging wires off of it,
and rotors on top of it, etc.
I know, on a shoe-string budget. Best of luck. We're not in the best of
places with the hobby, and everyone is fishing for ways to show that
it's a fun hobby and what you can do with it. Short of being able to
talk around the world when the power is out and "the towers are down",
there aren't many other selling points other than to EE students, and
EEs.
