Broadcast/Cable channels 39 are different ... only channels 2-13 
are the same.  

For Broadcast channels:  F(l) = 470 + 6 * (14-N)

For Cable channels:  F(l) = 120 + 6 * (14-N)  where 13 < N < 23
                     F(l) = 216 + 6 * (23-N)  where N > 22

F(l) is the low edge of the 6 MHz channel.  Video carrier is 
generally 1.25 MHz above the lower edge of the channel ... aural 
(sound) carrier is generally 5.75 MHz above the lower channel 
edge. 

73,
