This afternoon I've been hearing a net on 144.900 mhz FM here in South Eest UK with North American accents and call signs. Though I think one station was an M1 prefix so I think he was UK based.
I've been away from the 2m band for a long time so I am not up to date on latest developments there. Is this some sort of FM/Internet hybrid net...or very very unusual propagation !?
