All those pauses and waits are an artifact of later computerized/digital technology.
IIRC, it wasn’t uncommon for UHF dials to be continuous while VHF had precise stops and switched directly from channel to channel, so in UHF, as a practical matter, you'd have static between tuned channels, while that was not the case in VHF.
Its been a long time since I had a TV work a tuning dial, but that's what I recall.
