Hello, Hans

I've about made my mind up that it isn't going to be the hams that stop this
mess.

Of course, there are other users of low band VHF who may raise a stink
(especially once it gives them a problem). I am chuckling over one thought,
however. Yes, the BPL industry *claims* that they can put bandpass filters
on and largely eliminate nearby interference in a given band (such as
amateur bands).

I do have on question. Has anyone else in this group worked in an emc lab?
Especially an Open Air Test Site? I have. They are going to have to have
one pretty wide *clean* band to be able to test for regulatory compliance.
A band that will stretch from well below 10 meters up past our 900 MHz band.
They cannot test from inside an anechoic chamber; it must be an open air
site. I have seen a number of times that the ambient noise levels were too
high to allow testing. I can only imagine what happens if BPL gets pumped
through the power lines (street power is, perhaps, 200 feet away).
Hopefully, everyone understands that every new product utilizing rf (or even
digital signals above - I don't remember exactly - something like 10 kHz)
has to be tested for unwanted rf radiation if it is to be sold in the United
States (oh, and Europe, Canada, etc. etc.) Also, devices in current
production also have samples pulled from production lines and tested
periodically. Kinda hard if BPL is nearby.

Once the problem is finally figured out by the lawyers, the next problem is
who will reimburse the power companies if they then disallow BPL (word to
the wise: hang on tight to your wallet - us taxpayers to the rescue, once
again LOL).

As for technical acumen, the current state of affairs is such that even if
you really don't even know the difference between positive and negative, you
may well pass the exams for an amateur radio license.


Just my ramblings - but, still, hang on to your wallet.

Is anyone else embarrassed by the 'public sound and fury' antics of ARRL
in response to the BPL threat? Below is part of some correspondence I
sent to my Division Director. If you feel it's time for more sound
science and less hand-wringing, you should let YOUR Director know.

The valuable and responsible work of Ed Hare gets
lost in the "noise and fury".
