[TenTec] skywave BPL interference

[Eric Scace K3NA]

Hi Pete --

   If you experienced this kind of racket, why not file an interference report?

   A systematic effort to identify skywave interference from BPL systems could be helpful.  We know where some of these trial
systems are located, and what they generally sound like.  So let's see if we can hear them... and report it when we do.

   At one point ARRL had an "ARRL Monitoring Service" that would receive reports such as intruder reports, help gather a complete
set of data, and then report the problem to the FCC Enforcement Bureau, Spectrum Enforcement Division.  I just did a search on the
ARRL web site for information about this service and couldn't find anything.

   A search of the FCC website failed to uncover an electronic way of submitting interference reports.  Written reports may be sent
to:
 Federal Communications Commission
 Enforcement Bureau
 Spectrum Enforcement Division
 445 12th Street, SW
 Washington, DC 20554
There is an email address fccham at fcc.gov and a phone number (717) 338-2502, but that seems oriented towards interference reports
between amateur stations.  However, a phone call might be worthwhile to verify what to submit, how, and to whom.

   A report should contain information such as the following:
Particulars Concerning the Station Causing the Interference:
   A. Name or call sign.
   B. Frequency measured
   C. Class of emission
   D. Bandwidth
   E. Field strength
   F. Nature of interference
Particulars Concerning the Transmitting Station Interfered with:
   G. Name or call sign and category of station
   H. Frequency assigned
   I. Frequency measured
   J. Class of emission
   K. Bandwidth
   L. Field strength
Particulars Furnished by the Receiving Station Experiencing the Interference:
   M. Name of station
   N. Geographic location of station; telephone and email contact information.
   O. Dates and times of occurrence of harmful interference
Other particulars

   Recordings of interference are encouraged and should be submitted on a standard cassette.

Well, I found some very wide range digital racket from around 14.3 up to above 18.1 - beam heading 30 degrees east of north - while
listening for CW DX on the 17m band. This stuff had a good bit of QSB but when it was peaking at S5 it sounded very much like the
BPL audio clips. So I am pretty sure skywave propagation of BPL is already happening.

Another point that does not get the attention it should - probably because it's going to be hard to quantify - is interference to
BPL from "intentional radiators" such as licensed Amateur and commercial services. I get complaints of TVI when my local power
company's service trucks are working in my neighborhood - and when the police or fire department use their two ways within a block
or two - and I do not see how the very cheap BPL modems are going to keep from blocking from any moderately strong signal in the
HF-VHF range.

Even IF the utilities are willing to keep our frequencies clear that will solve nothing if we cannot transmit without blocking our
neighbors internet connections. I already know what happened when a CB'er's illegal amp blocked a satellite dish's reception.
Semiconductors ARE diodes, and diodes rectify. Whiteout! Followed by a shootout.

I don't want to have to answer my door wearing an armored vest with a shotgun in my hand - or call the county sheriff whenever a
stranger arrives in my driveway. And that's exactly what will happen if the Jukes down the road think anything I own or operate
might interfere with viewing the notorious Paris Hilton tape.
