Has anyone requested that they help? It's not the ARRL's job to fight
violation rulings made by the FCC. The ARRL can petition the FCC
concerning PROPOSED rules; they do a darned good job lobbying. But I
don't recall the ARRL interceding for a ham that's been NAL'd. This
guy just needs a good lawyer.

Concerning whether the ARRL actually does anything useful, I suggest
you study the history of ham radio and the role the ARRL has played in
preserving our wonderful hobby the last 70 or so years. The ARRL is
older than most hams. Besides, they put out a darn good magazine.

I have noticed the same noise pattern on different bands. From the buzz
characteristic
of the noise I guessed it was power line noise but I could not explain
why it was not
constant across the band.

Next, I connected an oscilloscope to the audio output of the receiver.
Expecting 60 Hz,
I synced the scope to the line frequency. Effectively I had a stable
pattern of spikes
but more than two spikes by cycle of the line frequency like if I was
receiving noise
from two phases of the power line. No big surprise there.

The surprise arrived when I tuned the receiver across the band. The
position of a set
of spikes moved relative to the other set until they superimposed. Past
that point
the noise would disappear on a part of the spectrum and reappear further.
(I do not
remember the details.)

Can anyone can explain the phenonena? Meanwhile, I am going for a power
line noise hunt.

In Canada, and also in the US according to previous discussion on this topic,
transmitters used in any service other than Amateur _must_ by type approved by
the DOC (in Canada) or the FCC (in the US) for _that_ service (in that country,
too - FCC approval doesn't count in Canada!)

However, unlike the current thread re operation on a sherrif's channel, if you
have a station licence for, say, the marine VHF service, you are very unlikely
to be caught and prosecuted for using a modified ham rig on a marine channel.

Please note that I do not advocate the use of unapproved equipment.  I use my
TH77 as a second marine receiver on occasion, and if necessary would use it as
a "lifeboat radio" in an emergency.
