Re: THREAT TO 222-225MHz Spectrum


 

Nothing new..in the early 80s we had offshore radio location under an experimental license in the UHF...10KW Pulsed wideband and center carrier of 439.200...wiped out the input of our local ATV rptr, which I was half owner...we tracked one down to a tower on the Gulf of Mexico and the license was posted there ..the company, based out of the UK , offered to buy us "amateur hams" linear amplifiers!! NNNOOOOO that wasn't going to fix anything...finally got them off the band since they were secondary to part 97 users under the license...

Geniuses. Give them an STA to operate IN THE BAND and expect them to not cause interference. Sounds like the federal government alright. Milair has their own band to operate in, why not do it there?

It's okay.. give it time, PTC-220 will be coming after 1.25m next anyways, since every railroad in the US is converting to the 220MHz band for all essential wayside functions.. it'll get jammed fast, and they'll need more bandwith, if they don't already.. they're already getting the boot out of the 800/900 segment by Anterix anyways, because 3MHz x 3MHz isn't enough spectrum for private broadband deployment, allegedly.
