The Crestline .575 repeater is the official "Radio TJ" non-english repeater in our area - it has a footprint roughly from north San Diego County east toward Landers and Joshua Tree Nation Park, well into Big Bear north east at least to Barstow, and northwest at least to Inyo County...
and yah, there are some long-talkers on that repeater .. Look at the radios behind me in my videos.. They're all set to Ch 16 / .575.. in my newest video I dont think they turned off once.
