Itinerant VHF business / industrial frequency, VHF high band. Recorded in downtown Richmond, VA. Unknown CTCSS (PL) or DCS (DPL) tone or code. 151.5125 MHz seems to be one of the less commonly used itinerants, especially compared to 151.6250 MHz, 151.7000 MHz or 151.7600 MHz. It is a narrowband “splinter” channel 7.5 kHz step from 151.5050 MHz (also an itinerant frequency). When I switch from memory mode to VFO mode, the radio was set to wideband FM deviation (25K) by mistake. I switch it back to Part 90 narrowband 12K mode. The TYT TH-9000D mobile VHF transceiver used in this video has WIDE 25K, MIDDLE 20K and NARROW 12K bandwidth modes. 25K appears to be the old 20K0F3E wide FM mode, 20K appears to be 16K0F3E or so (ideal for VHF marine band) and narrowband / 12K is 11K0F3E NFM, aka 11K2F3E, 11K3F3E or 12 kHz channel / 12.5 kHz bandwidth.

Antenna used is a 1/4 wave quarter wave VHF mobile antenna NMO mounted on the trunk of my 2014 Chevrolet Cruze.
