As an approximation, good enough for most tuners, the analogue channel frequencies are 3MHz lower than the analogue (although it's actually 306 - 303.25 = 2.75MHz). Since most tuners use channel numbers this 3MHz difference is not usually significant, but if you are trying to enter the act...
The letters ‘UHF’ stand for: Ultra High Frequency. UHF Frequencies Any radio frequency between 300 MegaHertz (MHz) and 3,000 MHz (or 3 GigaHertz) is considered to be in the UHF signal range. This range is less commonly known as the decimeter range. Frequencies immediately below 300 MHz ...
The 600MHz duplex gap and VHF frequencies offer interference and other considerations that constrain use. Together, these other spectrum resources are helpful, but are not practical alternatives to UHF, and the certainty of having access to at least one vacant UHF channel is...

(UltraHighFrequency) A range of radio frequencies from 300 MHz to 3 GHz. In the U.S., analog television has used UHF channels 52 to 69 in the 700 MHz band. Because of the transition from analog to digital TV, the FCC auctioned this spectrum to the highest bidders in early 2008 (see...
