Default BPL strikes another win ...

So while you are moaning and groaning about the problem, I will
be taking care of it myself in an orderly military manner.
Any problems they have will be due to their own shoddy system
design and line leakage which is a two way street I remind..
Not my gear. So they won't have a leg to stand on if they or even
you complain to the FCC.


Do you really seriously believe that if your amateur operation was
causing a huge company to lose money that the FCC or any other
government entity would take your side?

Boy, have I got news for you!


Yes Roy, it is incredibly naive! Just another of the hundreds of false
reasons why 'BPL won't affect me'.

I don't know of the situation in the US, but in Australia, a licence to
transmit on a given frequency does not override another law that in a
very general way prohibits interfering with a telecommunications carriage
service.

So, in Australia, it may be that no new legislation is needed to silence
hams who disrupt a BPL system (interfere with a telecommunications
carriage service).

Some of us continue to work on objective measurement of ambient noise
levels and BPL emissions to document to issue, and the risk to BPL
deployments if they are held to lower emissions than they would like.

Right now I am working on documentation of a series of measurements made
prior to BPL deployment in Sydney. Another series will be made after
deployment, and the measurements by an EMC test house and the WIA will be
considered by the carrier, the regulator, and the relevant Australian
standards committee in a more cooperative environment than seems to exist
in some jurisdictions.

Interestingly, the EMC test houses invariably use equipment that is not
capable of measuring ambient noise levels on HF, they are just not
sufficiently sensitive.

This is a worry, especially when rumour has it that ITU-R is working on a
revision of P.372-8 'Radio Noise' that is likely to see an increase in
expected ambient noise levels on HF. The inevitable creep of spectrum
pollution. As part of our study of the site in Sydney, we will be trying
to justify exclusion of the carrier's noisy SMPS on their PayTV equipment
from determination of the ambient noise levels.

OTOH, we have used a Buddipole and FSM to make measurements of ambient
noise levels that are not invalidated by instrument noise. An article
characterising the Buddipole for use with FSM is at
http://www.vk1od.net/buddipole/index.htm .

The fact remains that we hams do not well understand our operating
environment, and sadly, seem to have little interest in it.

Oh well, there will probably be more development of simulators for the HF
experience in the future!
