Well, here in Cleveland during that ime, while indeed being competitive, 
  broadcasters tended to shy away from the heavy use of clipping until 
fairly recently, so all the stations here sounded considerably cleaner 
than NYC.  Even though things have heated up a tiny bit since then, it 
still isn;t as crazy here as it is in NYC.

That was a big bonus for me as a small time neighborhood blaster!  :-D

Now, as you pointed out in another post, who knows what my actual 
modulation was back then.  When I realized that there was this thing 
called a modulation limit, I would use the cassete deck hooked up to the 
radio to check modulation levels by observing the left right meters when 
comparing what I was doing vs. everyone else.

It wasn't till I rescued an old collins Mod monitor from a dumpster bin 
in the later days that I was actually able to see what my modulation 
was.   The resulting level drop from setting things to the correct 
levels got me working on better clipper systems.  That opened the 
pandora's box, and I had to deal with the Gibbs effect, distortion 
cancelled and distortion controlled clipper systems, and ...composite 
clippers >:-)

The last station recording had all of the above on it for you to hear! 
Hehe.
