Hi Jim, I understand about the 2012 changeover, and all of our radios are capable.
However, if I can put together a backup repeater that will be a viable alternative for less than $100 that will last us until that time, I consider it a good investment. If I don't do it, we'll get hit by lightning & our only repeater will get zapped. If I do make it, then the weather will be fine, & it will have been a 'waste'. Just like insurance! :-) Thanks, Tim --- In Repeater-Builder@yahoogroups.com, wd8chl <wd8...@...> wrote: > > tahrens301 wrote: > > Hi Folks, > > > > I picked up a bunch of Micor repeaters today, > > and as I figured, they have the TLD xxx4 > > receiver in them.
