Philip Perkins Posted May 3, 2021 Report Share Posted May 3, 2021 Is the "duplex gap" @ 653 MHz at all usable in New York City? This would be for non-critical use on a stage, line of sight and not more than 70 feet or so. I have LP TX ants, but the RX ants have to be small onboard types for this use. thanks Quote Link to comment Share on other sites More sharing options...
codyman Posted May 4, 2021 Report Share Posted May 4, 2021 653 - 657 MHz, 20 mW (EIRP) - Part 74 License Required 614 – 616 & 657-663 MHz, 20 mW - Non Part 74 So technically you need a Part 74 license and you can't broadcast anything over 20mW of power legally. *Should* be open though.

I do now have a Block 20 IFBT4 with some R1a's there so slowly but surely I'm moving away from my outlaw past. But I will say I get range for days anywhere in the US of A using 658.600mhz as a hop...

Philip Perkins Posted May 4, 2021 Author Report Share Posted May 4, 2021 Part 74 no prob. Non-critical hop use. Thanks, New Yorkers! Quote Link to comment Share on other sites More sharing options...
Matt Geldof Posted May 4, 2021 Report Share Posted May 4, 2021 I can still find what appear to be usable frequencies in the block 25, duplex gap in NYC. As with anything related to production in NYC, the availability of frequencies change significantly from city block to block. With that said, I still have two Lectro 401s on block 25, but it has been some time since I have actually used them. I once in awhile bring them to locations in Manhattan, to scan and have ready, in a pinch, but have mostly moved over to 19-21. It is all quite congested, at this point.

newzhack Posted May 5, 2021 Report Share Posted May 5, 2021 653 to 663 is where all my wires are. They have been there since last November and I haven't had to retune since. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted January 1 Author Report Share Posted January 1 NYC duplex gap question update for NYC sound folks: any advice on this freq zone for the area around Lincoln Center? This is for a couple of G3/G4 type handhelds and the small battery powered receivers (no ext ants), for rehearsal use within about 70ft of range, inside a building. I know it's a dicey idea but I may be forced to go this way. thanks Quote Link to comment Share on other sites More sharing options...
