On COM4 (SDN)
93 transmitters radiate COM4 [V] — the main stations only, not the relays. By nation: England (66), Scotland (14), Wales (10), Northern Ireland (3). It is operated by SDN (ITV plc).
If this is missing, so is everything here
48 other services share COM4. A multiplex is one 8 MHz transmission carrying all of them at once, so it arrives whole or not at all — losing exactly one of these and keeping the rest is a fault in the channel, not in your reception.
