Vertical sweep rate is the same as NTSC: 60 cycles.

The horizontal sweep frequency is a bit lower, but you can feed a prewar RCA set standard NTSC; just adjust the horizontal hol control. There's more than enough range on the control to get sync at 15,734 cycles.

Sound isn't a problem, slope detection of the FM carrier works pretty well. The sound is a but distorted, but it's alright.

IIRC, channel 3 on the modern band plan directly correlates with one of the prewar channels, but I'd have to look it up.
