Why are cellular bands blocked on receivers? ka9wgn on 25/5/12
It is quite interesting that general receivers and expanded receive transceivers have part of the frequencies in the 33cm band blocked but those units designed to operate on that band do not. Obviously those units must receive the frequencies that are blocked on other units. I just doesn't make sense that one type of radio can receive in that range but another type cannot. Are 33cm radios designed in such a way that they would not be able to receive the signal images the rule is trying to protect?
