RE: Stereo Modulator?

["Keith Doxey" <lists.diyha@xxxxxxx>]

Hmmmm....

Given that the average synthesised (selectable 21-69 as opposed to the
screwdriver adjusted 30-39) UHF modulator costs more than that then I
seriously doubt it gives stereo. Terrestrial TV used NICAM for stereo
sound
so will need a NICAM Encoder to generate the digital bitstream, a
subcarrier
for the Nicam and also the normal analogue subcarrier for Mono Audio.

My guess is that it is a Full band modulator that has INPUTS for Stereo
and
mixes it down to Mono for modulation.

...of course I could be wrong.

Hi Mark

Each time that I've seen stereo RF modulators mentioned on the list,
people
have said how expensive they are.

This one covers channels 21-69 via dip switches and is
PAL I/PAL G selectable, so they're not FM band modulators.

If they do give a genuine stereo RF signal out then I'd reckon that
they're
a good buy.
