Depends on the locaction and what's going on nearby (and at the site). Sometimes you gotta do what'cha gotta do. If you expect everyone to play fair at a multiple site mountain top... you're going to have to revamp your view of reality a bit. One of our biggest pains is a GMRS linking nut in a private vault down the hill. Poop happens in the Amateur, Commercial and GMRS repeater input all the time. We often just use a bigger shovel. > Around here on 440 the input band is fairly well regulated. > Any TX that shows up in that band at a comm. site is highly > frowned upon. Then along comes the remote base from hell... nothing like a 45 watt remote base radio on an omni gain antenna to talk to another repeater 32 miles distant (line of sight). > We did have one "temporary link" show up at one site that > was pretty much in the middle of the input band, only 140 kHz > away from an input I maintain.
