AHH FYI, There is only 4 MHz between TV 4 and 5....
72-76 MHz....not 6 MHz! Used for radio links (only is areas where TV 4
and 5 are not allocated/used) and model remote controls.

136-144 is government use....satellites (wx, etc) MARS, CAP, etc...even
Russia's MIR used 143.625 MHz as a comm channel....

Take note that there is a 6MHz gap, a whole channel, between channels
4 and 5, which actually would be "in the way" more than the FM
