Frequency / Band Charts
With the encroachment upon the amateur radio frequencies by other entities and radio services, These are the frequencies that have been allocated for the use in Amateur Radio Service. If we dont utilize what has been granted to us. The priviledge may be given to other radio services as we have seen happen on more than 1 occasion. Let’s use it or we may lose it!
