I was reading the thread about seperating the studio from the transmitter.

The problem is getting an air quality signal from the studio to the transmitter.

There is a compression technology that uses two phone lines and some new gadgetry, which we use at KPFT to drive a repeater in Galveston.

It is outrageously expensive proprietery commercial technology, out of the question.

Sending analog audio over a phone line doesn't work, sounds terrible.

ISDN is outrageously expensive.

If you run coax between the sites, that defeats the purpose because the feds simply follow the cable.

The LPFM station in Immokallee FLA uses a very inexpensive com-link because their transmitter and studio are in different buildings.

Essentially, it is a version of a 'jack-box'. A computer power supply runs a two watt FM transmitter tuned to an unused frequency, the big broadcast transmitter is hooked up to a common home stereo receiver.
This solution is good for a quarter mile seperation and is very affordable..

This might slow down the feds, obviously one would want to dismantle the display on the FM receiver at the transmitter so the feds must figure out the com-link frequency and have to triangulate a very weak signal back to the studio. Which they CAN do, but it takes time, and once the broadcaster hears their air signal taken down, they can stop broadcasting the com-link.

This might work ONCE, the FCC owns a Radio Frequency Analyzer, and the next time, they'll just flip that thing on, and look at everything on the band and track both sites before calling in the storm troopers.

Using the net with two cable connections and two dedicated computers, one at each site, using a 64 kpbs non-publicized, dedicated mono stream is a potential solution, very good as far as anonymity (unles the FBI weighs in and subphoenas the I-net provider) however, there is a 15 sec to 2 minute delay involved, and two cable connections is an eighty dollar a month bill to pay. Running a 24/7 broadcast, relying on the stability of the net and the local cable provider means there will be fairly frequent occurances of dead air.

Wireless modems, chained together could establish a com-link between the sites which would be a bitch to trace. I'm not up on this technology , but these units only cost about 60 bucks and do not rely on the net, I think their range is just under a quarter mile, but I believe they have to be wired to a computer, which means the initial investment is pretty steep.
