The Knight Patrol guys even had a network of 11 meter FM repeaters operating in the 27.6 to 27.8 MHz region, same 100 kHz split as 10 meter FM repeaters IIRC. They all had 88.5Hz CTCSS or PL tones and were apparently linked to each other. There's a YouTube video out there showing a guy keying all the repeaters up from somewhere in the Caribbean. I don't think any of them are on the air anymore
