My first attempt at posting this was likely sent astray. -- As the majority of DTV are on UHF (or high-VHF) the effects of any line noise RFI ought to be much less than what the low-VHF NTSC suffered

145.25 is the CATV Ch 18 (Ch E) NTSC video carrier frequency, and on an (FM) HT it will sound pretty much like unmodulated dead air. The audio for that is 4.5 MHz higher (so out of the 2m band). It's
