1610, 3220, 4830, 6440, and many more frequencies. The frequencies
below 6440 KHz should have been limited to the Knightstown area during
the daytime.
6,440 KHZ and up are a different matter. These frequencies may have
gone hundreds of miles on very little power. And, the antenna copied from HCJB must have favored Short Wave more so than AM. So, most of the power was really on Short Wave.
The FCC could explain the above. What they could not understand was
how this got into WIBC. But, some Short Wave frequencies can really get
into old 1950's tube type audio gear.
