| Don't hold your breath on anyone doing anything about it.
| Regulators wont even go after intentional interference.
|
| See: The guys in the southern U.S. running 10,000-100,000W AM
| transmitters with dirty amps that splatter 6 CB channels at a
| time across half the planet. And all they do is yell gibberish
| and try to drown each other out 16 hours a day, making swathes of
| the 11m band unusable when they get bored of 27.025 and start
| moving to higher channels.
|
| They've been doing it for 30-40 years, and people have been
| complaining and reporting it the entire time.

| Your fellow canadian VE7KFM is one of the worst offenders:

| and not shocked at the behavior.

| Yes, but has a major purchaser of spectrum complained? No,
| because its CB and they're not interfering with AM/FM
| broadcast, first responders, aviation or cellular bands.
| Therefore, nothing will get done and I doubt the FCC is even
| monitoring it.

| That may work as a starting point for groundwave, but

| That "tool" needs to go away. Time and time again people get
| accused of causing interference because their station falls
| in the center of the heat map and the person using completely
| fails to understand what it is they're seeing.
|
| I was so annoyed at this going public that I pulled my Kiwi
| off the internet. Nice experiment, interesting code problem
| of synchronization, failure to let the public use it.

| Not buying they're running 100,000 watts, nor much over a few
| kilowatts. Which, isn't in any way acceptable for a service
| that limits AM to 5 watts.
|
| Splatter isn't indicative of large amounts of power, just an RF
| amplifier going very non-linear.
