From what I understand, SafeTV gave up its KSBN call letters because it was such a large cost and apparently they didn't get enough support from the local area to pay for the license.

I know that 3ABN has a lot of UHF channels. Does 3ABN ever question if these are worth the expense?

No, It seems we have the best of both worlds in some cases. Let me give you an example. We have a UHF station in St. Louis that has an incredible potential viewing audience. But since it is considered low power even though it reaches all of St. Louis and beyond, it cost us very little to operate. Our power bills for instance are usally hundreds of dollars a month versus thousands of dollars a month for full power transmitters.
These UHF stations have proven tremendously effective over the years for the saving of souls, not to mention that many if not most are worth $1,000,000 and more. If we choose to sell them we believe that some of our class A stations could bring $2,000,000 to $3,000,000 apiece!

Also, I believe 3ABN owns close to 100 of these stations. The math on their worth is fairly simple to figure.
