Using Reverb

Ron's answer to my post about chasing AM/FM DX- 690 and reverb brought me to rememberence of something. I agree with Ron in that the reverb-laden voice is an ear-catcher!

I remember reading somewhere, early in my hobby radio enjoyment, about how the light use of reverberation, or "echo" can make a signal cut through static and noise a little better. When single-sideband (SSB) came into heavy use (and some Hams talked against it when it started being used in Amateur radio!), reberb was inserted into the audio to keep the signal "up" a little longer, giving it a little more punch or "hang-time". If you could visualize a spike being one word, with one sharp point, inserting a light bit of reverb would cause a flat-top spike, being a little longer in duration.

During the '70's CB craze, some people started using "echo boxes" and inserted 'way too much reverb on their CB signal, making them UN-intelligable!

Needless to say, commercial stations, when done correctly, benefitted from reverb, as we heard in Ron's audio example. Who can't remember when some exciting event was being advertised, and there was nice reverb used in production? Sure caught our ears, didn't it?

There's a couple of posts regarding reverb as it was used at KAAY here:

Quite interesting, the manual/mechanical methods back then! Nowadays, electronics do it all, but there's something about mechanical means...just like older tube gear, there's a warmth to it, in my opinion! I experimented with a child's toy light saber/sword years ago, which had a spring in it, was quite interesting, playing with it- just a slight shake would produce interesting results!
