No law, just alternate ways of getting around this. It's unfortunate that you can't use celluar phones for 'Remote Broadcast' without an STA (Special Temp. Authority) (does the FCC plan on changing it's mind about this soon???), but you can use some device made by Wenger (or was it Cetec?) that basically companded an audio line, 'split' it in 1/2, and used 2 normal voice grade telco lines (read: regular telephone calls), and provided 7.5khz of bandwidth at the distant end. Mutual used this for remote Larry King shows. the only problem was disconnections of the phone line (I seem to remember Mutual using 4 lines, the other 'pair' being a backup). All you needed was 2 POTS lines at the remote site. But in your case, Blockhead-Tel....err...Rochester Tel probably still needed 3-4 days lead for the POTS lines also, unless there was some pay phones near by that had accessable demarcs or even some exposed drops.....naaaahhhh, that's 'illegal'......... There's also satellite flight-packs that come in about 3 large suitcases and a small dish (3-4 feet), and then you can shoot up a 15khz SCPC line into the sky onto a Ku bird. 'Wolfman' Jack did that for XTRA-AM in Baja California for a while. The point being made here is that there ARE alternatives nowadays, and the telcos need to be made aware that people can and WILL use them if they keep this type of attitude. I will readly admit that the lead times for ordering and installation of long-line audio circuts has dropped, but not fast enough to keep up with technology.

Back in 1982, Comrex had a frequency extender that got 5khz flat response, more or less, out of a regular voice grade line. There were a couple of models, but each was basically an audio mixer for three or five inputs, for a few mics and a cart machine. I'm sure that it's old hat by now. ------------------------------------------------------------------------------ Bob Izenberg [ ] attctc,rpp386,cs.utexas.edu!puzzle!bei ------------------------------------------------------------------------------
