[TenTec] remote control (wired) solution, cheap!!!

[tongaloa]

If anyone is in need of controlling a serial device at
a distance of up to 18,000 feet. I have some surplus
adtran ISU 128 units. They will do up to 115.6kbps
async or 128kbps sync between a pair over 18,000
feet of mixed size twisted pair (like a dry telephone
company alarm cirsuit) or up to 5 miles over good
quality, unbroken (no junction boxes) twisted pair.
$60 for a pair of the adtran units includes 48 states shipping
and I have 5 pair to sell.

You might use for remote of these GPS receivers or
with a PeeCee at each end having soundcards, you could
run streaming audio and control signals for a pegasus or
other radio with RS232 or sync serial control.

Users manual is online here:

and operation is described on page 40 of the manual (acrobat viewer 
counts actual,
not numbered pages so it's around page 55 in viewer) Section is leased line
configuration.
