As more and more frequencies are put into use for fixed services (eg. links and repeaters) it becomes very important to have the frequencies coordinated to eliminate interference. To this end the ARRL maintains a system of frequency coordinators in each area of North America who maintain a database of frequencies in use which they use to recommend optimum frequencies to those amateurs wishing to set up new facilities.

The coordinator does not ASSIGN frequencies, only recommends, as he has no federal regulatory power and compliance is voluntary. Ham radio is basically self regulating and this is just another example of what can be done with a little co-operation. There can be no guarantees that any given frequency will be completely free of interference, but the coordinator will do his best to ensure that there is frequency and distance separation between stations.

As a matter of interest there are 248 coordinated frequencies in use in Saskatchewan in the vhf and uhf bands. Frequencies for linking in some areas of the province are becoming difficult to come by on the 440 MHz band.

Anyone wishing to set up a facility should contact the Saskatchewan Frequency Coordinator, supplying details such as location, call sign, station sponsor and preferred frequencies.
