This is why I think the FCC should carve out a CB band in the 220mhz section. open up 2Mhz and allow repeater operations. No license required.
This way people can set up repeaters etc.. and not have to deal with getting a license for general chitchat operations etc..
pop up a couple of repeaters in the neighborhood and get some Woxuns on the air.
Sooo...You are proposing the FCC allow the general public to be able to install unlicensed repeaters up that will ultimately have modified/china amplifiers, no filtering and other "modified" equipment and spew second, third harmonic/IM spurs all over the place ? Sounds like a great idea (sarcasm).

Not to mention second, third order IM issues.
Properly engineered radio systems will filter their transmitter outputs, as well as receivers. The public safety systems I maintain run 110 watt repeaters. After filtering/combining I am getting 60 watts to the feedline...if I am lucky. Some channels only do 40 watts to the feedline. We filter stuff to prevent interference from others and creating interference to my own systems. We also filter our stuff so we are friendly RF neighbors to system above and below our licensed channels. I have a prime VHF simulcast site that has a 1,000 Watt Weather transmitter co-located on the same tower.....zero interference. Why ? Filtering.
It's pretty common to drop $10,000 in TX/RX filtering for a properly engineered public safety repeater site handling a few channels. There is a lot that happens in the background you are not aware of with radio systems that follow good engineering practices.
There is a ton of math, physics, engineering and planning that happens when allocating spectrum that the FCC has to consider. Most of this stuff is beyond the abilities of us on RR to understand or never even heard of before. There is a reason ham bands are where they are at for planned interference and harmonics.
We all know if the FCC allowed unlicensed repeater operation, folks wouldn't follow the rules, hang dirty, nasty amps on the things and not care about RF purity just so they can get another 100 watts of RF output.
