Hi Tom 500kHz is 32 times the 15.625kHz line frequency for 50Hz framing TV
sets. That is why I suggested to the RSGB representative that we do not ask
for an allocation at 500 exactly !! I remember this as in the early days of
personal computers we used to generate TV line sync by dividing a 1MHz
oscillator by 64.
