Hey, ironbear..if you'd be willing to connect, I'd love to chat...it's hard to put into words what that time of my life was like, and it's very, very cool to hear about stuff that I grew up with in my basement being used for other great broadcast purposes...this was intended to be edited, but the webmaster posted the whole thing...brief synopsis of the 70's time line of KBAZ/KZMK. As I remember it, KSUN's owner did have the original c.p. for 92.1...but let it lapse, and that's when my dad came in.

So...you bought the equipment from Casto, the GM, or the engineer??? Yup, my dad picked out the xmtr site, one of the highest points (highest?) in Cochise County...50 watts did a lot of damage at that altitude

Future owners sold/traded the 92.1 to 92.3 to make a buck..ironically to/with the same Tucson group I'd end up spending most of my career with...maybe my dad would have done the same thing.
Not sure if you can see this, but here's a link to the newspaper article when we (Copper Valley) were first up and running: https://www.facebook.com/media/set/?set=a.1149629274295.23601.1634511481&l=c823062910&type=1
Thanks for a great post and for all the background on KBAZ, and when I said 50 Watts can sound like a blowtorch, I wasn't kidding. I appreciate the heritage of that equipment even more now, and you now know that the good Karma came with us to Flagstaff. I was dealing with Dave Casto the GM, who later ended up in Cottonwood at KSMK, and Palmer Stewart, the OM. It seems possible that our paths crossed while I was at the station.
I've always related to your dad's path to ownership, which is much less possible anymore. With all the changes and consolidation that's happened, remembering the spirit of the real entrepreneurs who made it happen seems important.
