Not sure whether this is a policy change or just a clerical error...
For years, there has been a KFMT-FM on 105.5 in Fremont, Nebraska.
On Tuesday... the FCC assigned the calls KFMT to a new FM station in Lewistown, Montana.
Now, the calls *are* different. (no -FM in Montana) However, it's not been FCC policy in the past to allow the same four-letter "base call" to be used on two different stations in the same service by using or not using the -FM or -TV suffix.*
* it *has* been permissible to use them on two different stations in *different* services -- for example, on a full-power TV station and a LPTV. (WPXJ-LP Jacksonville, Florida and WPXJ-TV Batavia, New York, for example)
