The differences between PAL NTSC go way beyond modulating RF. Even at
baseband, the monitors will be different one may not work with the other's
signal. The Frame rate, or vertical interval is different - NTSC based on
North American AC at 60 Hz, as opposed to European 50 Hz, and the Horizontal

A modulator for PAL is different than NTSC! PAL receivers use different
frequencies and I also think there are other differences!) . However, I
would assume that if you're in a locality that has PAL receivers then you
should be able to easily get a PAL modulator.
Remember also, that most new
Yes, they will spit out PAL format, but again it will be unmodulated so
I suppose you will need baseband inputs or a modulator as I do.

You can pick up a not feeling well or dead - older VCR in thrift shops or

Does anybody know if the 8590 series can spit out PAL format ? and if
the same modulator would do the job ?

Radio Shack sells an RF modulator that will do the job. If you feed it to a
VCR you can also record the results as well as view it on a TV set. As
mentioned, it produces NTSC compatible video on CH3 or 4. Price should be
around $25. U.S.

QQPX2 would be the UL category you should check. ITE or other type power

There are many things one needs to consider when dealing with Explosive
