Hi, Marty

I'm the happy owner of a "Magic Notch" filter, which goes
between the receiver audio output and speaker. It has a
built-in 2 Watt audio amplifier, and requires a 12 VDC wall wart.


Tnx Ed, et al.

Duly noted are the "magic notch,' the Datong FL1/3, & the "monitor's pal"
hetrodyne hunter-killers.

Tnx

But, still haven't got an answer about the Rad-Shark's guts & possible
mod. But perhaps that's a futile quest.

Why do I ask at all? Well to replace the lost adjustable-peak audio
filter in a Navy RAL regen. That's why.

Again, tnx

Marty
