FCC endorses BPL, another threat to ham radio
 

Look up FCC rules Part 97.121 among others. I personally know a
licensed
amateur that was using Approved equipment, who never the less had his
operating privlidges restricted in & around his home simply because
People called & complained about TVI, & the FCC cited 97.121 in their
letter to him as the reason for the restriction.


OK. I did, and here it is:

S 97.121

(a) If the operation of an amateur station causes general interference
to the reception of transmissions from stations operating in the domestic
broadcast service when receivers of good engineering design, including
adequate selectivity characteristics, are used to receive such
transmissions, and this fact is made known to the amateur station
licensee, the amateur station shall not be operated during the hours from
8.PM to 10:30PM local time, and on Sunday for the additional period from
10:30AM unti 1PM, local time, upon the frequency or frequencies used when
the interference is created. (b) In general, such steps as may be
necessary to minimize interference to stations operating in other services
may be required after investigation by the FCC.



I don't see where the above applies to Internet service providers.
They are not licensed stations, per se, anyway. You might also note how
cable TV stations are dealt with under similar circumstances. They are
always at fault if there is an RFI problem.

broadband DMT modems do not have selectivity. They use wideband filters in the front end and line driver areas (or perhaps none, in case of annex C) and do the frequency selection in DSP. They don't have "adequate selectivity
characteristics". But then I assume too much about BPL. I think the selectivity clause will stick though.

Nor are they receiving transmissions from "stations in the domestic
broadcast service". In fact, BPL systems do not appear to me to be
"stations" operating in _any_ service. Hence, I don't think that
either clause of 97.121 applies.

That's not to say that the FCC won't contrive to pull a "through the
looking glass" inversion, and come out with a ruling requiring
licensed radio services to shut down to protect unlicensed land-line
services.

This should not be a problem, You are represented by the Omnipitent
and SELF SERVING, ARRL.. BUT WAIT. They do NOT carry anywhere
near as much clout with the FCC as they used to. OH WELL!!!!! BFG

Gee, their goes 20 meters with all those "California Killowatts"

Gee, Their goes 160 meters with all the bootleg AM broadcast
transmitters..

Gee, there goes all those *ssholes with their Multi Killowatt 75 meter
AM phone rigs Splattering 20 Khz either side of center..

Glad they finally stuck it up the Anal HF groups *ass.


Just my opinion..

Bob


the FCC seems disposed
to encourage it anyway. evil! evil! just look up BPL on the web. The noise from the radiated signals trashed the ham bands thoroughly.

I think the ARRL is important as it was 43 years ago.

I'm a 43 year supporter and I will be as long as I'm a air breathing
walking talking ham.

The ARRL is us. It is our voice in Washington.
