Maybe it's not intentionally blocked...just not enabled. What I mean is,
many scanners do not have true, continuous coverage. They have portions of
the spectrum left out, because there is nothing in that range to listen to.
I'm not aware of anything that would be using those frequencies, 620~630MHz.
I think they do this in an effort to optimize the receiver for the areas of
the spectrum that it does cover. I used to think they were left out, to
prevent us from finding out what's really going on, in those frequencies.
However, having true, full coverage receivers/scanners, I found they were
void of any activity.

Can anyone offer a reason why 620-630 MHz. would be blocked on a
VR-500? It clearly is not a cellular range. Thanks.
