Hi,
Does anyone in this NG know of a manufacturer, preferably in the UK,
that produces small(ish) narrow-band [25-50KHz] synthesized VHF FM
receiver modules that will cover the frequency range of 136-174MHz
*WITHOUT* physical retuning? There'll probably be a requirement for
30-50 of these, if they can be found.
Various companies produce modules that can be tuned to cover just a
few MHz out of the above frequency range but I'm looking for one that
will instantly tune to any frequency in that band just by programming
the synthesizer. I need better RF performance that can be achieved by
simply adapting a scanner and, in any case, am looking for a unit that
will be available for a few years to come.
Any thoughts or constructive suggestions will be most welcome.
TIA - Dave
