[Elecraft] K3 in the CQWW contest

Hi Matt

Most of us are black box operators. We need regulations for the amateur service that specifies how our transmitters must perform, just like every other HF spectrum  user.

Its amazing how the amateur service holds its head up high as some sort of technical  demigod society, yet we cant even clean up our own camp. 

Arguments that transmitter standards interferes with technical development is a nonsense argument in my view. 

Its time that the ARRL lobbied the FCC  for standards for amateur transmitters, and these standards should include keyclicks and SSB transmitter and amplifier IMD levels. 

We know keyclicks are unacceptable, why would it be so hard  to specify by how much keyclicks should be suppressed by  and what the maximum bandwidth should be? How does setting such standards interfere with technical development?

We already have standards for harmonic and spurious  levels. The FCC said a long time ago that we cant interfere with televisions or other services if our transmitters are crap. They set harmonic levels for transmitters. Its now time for them to say its also unacceptable for hams to interfere with hams using crap equipment.

Its a disgrace that anyone can go buy a cheap 12 volt mobile radio and then go buy a cheap RM Italy amplifier  and then get on the ham bands and call CQDX. Its equally sad that such operators think that they are legally entitled to do so  without worrying about the  consequences to others. Its selfish and not in the ham spirit. How is it fair that this kind of brain dead operation is classed as "technical experimenting" when it causes so much  interference to others?

Why the law stinks, is that if I decided to  tune up on this individual for  1 hour I would be breaking the law because I am causing deliberate interference. Yet if I use a class C CB amplifier with a substandard transmitter it would be okay to cause interference all day  and I am legal.

We need to wake up to ourselves and  our regulations.
