That is certainly interesting.
Back in the day there used to be various modifications for scanners such as Bill Cheeks 4 level discriminator which got him in so much trouble.LSM=
L=Lousy S=Stifiling M=Motorboating
As opposed to:
Linear simulcast modulation

Now by design, we have a factory installed 4 level discriminator that is lousy at decoding LSM . So we need an I/Q demodulator for that.
I propose a LSM to C4FM translator circuit.
Uniden and Whistler probably won't spend the R&D to upgrade to their product line. But a third party could engineer a fix. Think of Sherwood and their filter and synchronous AM upgrades for shortwave radios.Maybe the scanner manufacturers should just design a modern product that has an I/Q demodulator for LSM? Unication did it. Our agency has 2 demo G5's. Guess what: they pass PERFECT audio as good as our APX radios and cost not too much more what these garbage pail crap scanners do.

Could someone in English (plain) explain the difference in a regular site and a simulcast site.
I do know what 'simulcast' means but how does it apply here? Thanks much....
