Looking for OEM narrow-band FM receiver modules [136-174MHz]

Sep 29, 2006 0 Replies

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
