At one time you knew where in the USA a station was located by its call area. No longer. A W6 can be in New York and a W1 in California. In my view this is a very backward move. Although it has been the case for a few years, it is now beginning to become a major problem.
Is this an FCC issue? They do seem to be so behind. 472-479kHz is still not allocated in the USA whereas we've had access to the band for 1.5 yrs now here in Europe. I don't think they yet have the 136kHz band even!
As an occasional user of the USA customs service, I wonder if the FCC uses similar people? The USA customs officers seem to be a "rum lot" with absolutely zero sense of humour. Where do they find these people?
