Just FYI PAL-M subcarrier is not 4.42 MHz. The 4FSc is 909 times H rather than 910H for NTSC so the subcarrier is a little lower than 3.58. That said, I don't know how you'd play it back and convert it to NTSC.

Hi,

Any idea how you could playback a PAL-M recording on an Ampex AVR-2.?

The AVR-2 is a PAL/625 at 5.5MHz<mailto:PAL/625 at 5.5MHz> machine where the PAL –M recordings format is 525/PAL at 4.42MHz<mailto:525/PAL at 4.42MHz>

Any info  would be much appreciated?

Kind Regards,

Ian
