I'm a seasoned DXer here too, SomeRadioGuy.
Well, nowadays 'marinated' might be more accurate.
But in the 60's and 70's, we couldn't WAIT for new AM stations to sign on, serve their town, and come in by us.
'Us' lived near JFK Airport in Queens. Some of those new shoehorned stations (all of them seemingly directional) were very good.
WINE 940 from Brookfield (Danbury) CT was one of the first. WGCH 1490 Greenwich CT signed on around then. Later came things like WTBQ 1110 from Warwick NY .... WRAN Dover NJ 1510 .... WKER Pompton Lakes NJ 1500 .... WBRW Bridgewater (Somerville) NJ 1170 .... WKDN 800 Camden changed to WTMR ....
Well, I'm just lamenting about how these new stations sounded quite 'individual', for lack of a better adjective.
Even the older ones, such as WNLK Norwalk CT, WNAR Norristown, WTEL 860 Philly, WFPG Atlantic City 1450, et al, were unique and faithful to their COLs. It was stations such as those which made me (and I'm sure others) want to try our hand at this community communications stuff.
And get PAID for it, lol!
Much as you had, I did 26 years straight at radio, back in the days of yore. And as a DXer I had no quarrel whatsoever with new AM stations signing on.
FM has become another matter altogether, with all the new translators, duplications, relays and extension speakers. It's beyond comprehension to imagine a 16-year old kid scanning the newer FM dial in 2019 and being enthralled enough by all the duplication and indifference present to make him or her want to approach the industry.
And radio is chewing its nails for some reason?
