[600MRG] It seems reasonable to assume UTC will continue opposition to Ham Radio 630m and 2200m operations

[Brian, WA1ZMS]

We (Part 97) are being singled out as a "special case" by UTC.  I think it's
a combination the fear of the unknown and following the money.

1) UTC sells frequency coordination services for many RF bands, just one
being PLC from 10 to 490 kHz.  Yes, it's Part 15 and they ought not be
granted any protection in any way.....but.....the FCC has ordained the UTC
as a frequency coordinator for much of the FCC licensed utility spectrum as
well.  

2) Those coordinations are made by charging the utilities a fee. That's the
$.

3) The fear comes from not knowing just when and where the Part 97 users
will show up.  The UTC knows where DGPS is and that it will be on 24/7, so
they can tell a utility to not use a proposed PLC channel that near a DGPS
station.  That's what the utility is paying for anyway and have come to
expect. Enter us hams. Upsets the status quo. The UTC will be the first to
be held accountable for QRM to a PLC system that some tiny local power
co-operative that paid for to be coordinated.  "So why did I pay protecting
my PLC if some ham can jam it!?!?" the utility could say.

4) Now we as RF guys know full well that the PLC could never offer
legitimate "protection" of any kind to a Part 15 user, but they said they
could and charged for it.

5) If we hams had the $ to offer-up to the UTC to co-ordinate us too, I'd
bet you they'd do that too in a heartbeat.

And what about all the other licensed transmitters in the LF and MF bands
like the old GWEN and DGPS transmitters and MF air and maritime beacons not
to mention the Minuteman WS-133B MF system, etc. ? Did UTC approve them? I
don't think so. Why are they picking on us? Marshall, W1HK, #41

company technician complaining that our AM station was "interfering" with
one of their control carriers on a power line.  I explained that we had no
responsibility in that kind of situation but I'd be glad to help him figure
out what was happening.  I asked for confirmation that it was my station -
he said he could hear our audio perfectly when he listened to the system
with the speaker on the front of the receiving unit.  I asked what frequency
their carrier system used - he said 1.31 MHz.  I then asked what form of
modulation their system used - the answer was amplitude-modulation with
modem tones as the audio.

our 5000 watt station on 1310 kHz - they had managed to tune their system to
our signal exactly and have the biggest receive antenna in town!   I
suggested he tune their transmit and receive units to another frequency -
one that wasn't in use already by broadcasters in our city.  He wanted to
know how to pick a frequency.  I suggested he go out to his vehicle and turn
on the radio and find a frequency that didn't have a strong station on it.
He didn't seem to understand so I just told him a couple likely channels not
near our frequency and wished him good luck.
