Am having issues with my EV R300 set
The RF signal is OK but no AF signal yet the channel on the receiver and transmitter is OK
I have tried even changing the frequency but no help.
What could be the problem?

It could be a problem with the microphone itself, or MUTE may be slected; please check connections and replace mic if necessary.

question
EV Technical Support was cluelesss and told me they don't sell this in C Band in the US and that there are no issues with 600mhz soon being obsolete. Their Frequency Finder webpage says there are no useable frequencies for this mic in the NYC area. Anybody using this wireless mic system with C Band in the NYC area?
The Electro-Voice R300-HD is available in the C-band (516MHz-532MHz), and currently can be operated in the NYC metropolitan area.

question
What will happen when starting 2020, most of the 600 mhz range will no longer be available to wireless mic users?
The Electro-Voice R300-HD handheld wireless microphone system in frequency band C operates below the 600 MHz range; 516-532MHz. You will have no immediate need to change your system. Here is some more information directly from the FCC.gov website: Wireless microphone users, whether licensed or unlicensed, may continue to operate on a secondary basis in the bands that continue to be available for and used on a primary basis by broadcast television (TV channels 2-36). Use of these TV band frequencies, which fall below 608 MHz, remain available for wireless microphone use after the incentive auction. FCC 15-100, FCC 15-99 Licensed wireless microphones may also operate on the specific frequencies in the 600 MHz duplex gap (652-657 MHz), and unlicensed wireless microphones may operate on a portion of the 600 MHz guard band (614-616 MHz) or a portion of the 600 MHz duplex gap (657-663 MHz). FCC 15-100, FCC 15-99, DA 17-314.

I see on the back that it has a 12V 500mA input power jack. Does B&H sell an AC adaptor that works with this system? Also, does the microphone also require batteries, and if so, what type? Thank you!
Unfortunately the description of the Receiver does not indicate whether an AC adapter is included in the package as sold.
The description, however, makes it very clear that the microphone (sender) uses 2 AA alkaline batteries which should work for 14 hrs.
