Hector,
Off the shelf radios are not going to have the expensive notch filters
and oscillators necessary to really narrowband a transmission. How
narrow do you want to try and are you going to use a digital receiver to
discriminate or the old school home build regenerative? Interesting
stuff for sure, regen is the system that was superseded with the
superhet IF stage which is wasteful but easier to quiet. Could probably
use a hybrid design digital control and filtering of regen to see how
far one can take Q and selectivity without drift.
