Deciding to pull the plug on obsolete technology is very hard when you are in the middle of the transition.Putting the tower further away from the station wouldve resulted in the problem that befell KIYU-AM.. not on city power/ They ended up turning in the AM license. Fuel was costing $60,000 plus a year for just the AM ... same reason why KSKO turned in the 870 license
In 1966, I bought an AM and Short Wave station in a town way outside of Quito, Ecuador. I suddenly had a great AM frequency, 590 and a SW station somewhere in the lower Tropical Band that I can't remember. My intent was to move the AM to Quito where it fit perfectly on the local dial.
But as I looked at the station in the town of Amaguaña, there in front of me was a 500 watt short wave transmitter that was totally "home made". Open cabinet, with exposed wiring and final tubes and antenna matching coils. Dead flies inside, victims of their own St. Elm's Fire from a couple of 833's.
The station was in an adobe structure with asbestos sheeting on the roof. The floor was compacted clay (known as "mud" when it rained").
I knew I could not use the gear. I realized I could not make money with the shortwave frequency either. On the spot, I arranged for the transmitters to be taken to the city dump, a ravine outside of town. I said that the desks and other stuff could be given away by the seller.
I walked to my car with a contract and two licenses. The next day, back in Quito, my lawyer went to the equivalent of the FCC and arranged for the short wave frequency to be cancelled and the AM transferred to my company.
I would have loved to have had a short wave station just to get those international reception reports. But there was no way to make money with one, and I never regretted making the SW facility go silent.
