A few answers:
It appears that the Tuckers have an arrangement with Good News Broadcasting that allows KRDX to have a telephone and probably a few square feet of office space at the Good News location on Richey Avenue in Tucson.
It has now been ten years since the Tuckers bought KKYZ for $500,000. All sorts of confusing proposals have been filed with the FCC relative to moving KKYZ and none has as yet been implemented. One called for moving the station to Saint David and another to Corona De Tucson. At the present time KKYZ holds a construction permit to serve Tanque Verde on 101.1, thus giving that almost non-existent community two FM stations. There has also been a proposal to allow KKYZ to remain on 101.7 in Sierra Vista, sort of like having a cake and eating it too. When KKYZ finally does move to defacto Tucson, it will be sold for at least 20 times what the Tuckers paid for it and maybe a lot more than that.
My information is that there was an offer to buy the Benson station for a smilar price but the owners turned it down. I think they wanted a decent price if the new owners were eventually going to make out like bandits. I also think they were down on having their full service station made into a computerized jukebox.
I'd love to see a trade publication like Radio World or Broadcasting & Cable do a feature article about making millions on frequency swaps including the filing of proposals with the FCC that the applicants have no intention of constructing. That will never happen due to fears of libel suits. Meanwhile if the spectrum is public property, the Brooklyn Bridge gets bought and sold over and over.
