One of my big purchases for 2012 will be a second SRa receiver and two more SMQVs. My current SRa is on block 21, and here in northern NJ I’ve found block 21 to be incredibly vacant. I’ve used it all over NJ, NYC and Philly, and never had any problems with interference (of course I always scan the frequencies first.)
It will be used in a bag holding 2 SRa’s (with a Lectro Quad Pack) and a Nomad 6 which (surprise, surprise) I don’t have yet.
So why shouldn’t I buy another SRa on the same block?
