It would be good to figure out at least 1, if not 2, common frequency to declare as RS1 & RS2 for 70cm simplex. I needs to work within both Colorado and Utah's band plans, and not step on a repeater in either state.. that was essentially the effort behind the 4 RS frequencies on 2m. Beyond that I'm not sure what other concerns there would be?
Utah guys- do you have any default 70cm simplex channels you use?
