Microwaves
The Microwave region of the spectrum strictly begins at 3GHz but amateurs traditionally refer to all the bands above 1GHz as microwave bands.
It is perhaps the most challenging and technically progressive area of amateur radio.
With the exception of kits and modified ex-professional gear, there is very little commercially built amateur equipment for any of the microwave bands—apart from 1.3 and possibly 2.3GHz.
It is also an area of the spectrum that is under sustained pressure, where many different (and often conflicting) demands are made for frequency allocations by commercial, government, military, domestic and amateur users.
Never has there been a more appropriate time to remind all amateurs of the need to “use it or lose it”!
