Recently, in a futile attempt to receive WEFAX satellite transmissions,
I bought a VHF converter for one of my shortwave radios.  Since the
satellite broadcasts turned out to be discontinued, I started looking for
other things of interest nearby, and found something unusual.

On 152.780 MHz, there is what sounds like a telephone ringing, all the time.
I have been listening to it for about 3 hours now (while doing other
things) to see if anyone ever answers, but all that happens is that the
amplitude of the ringing changes from time to time.  It is a very normal
sounding ring signal, like you hear when you place a phone call.

I am wondering what this is?  According to my frequency allocation tables,
it says this frequency is allocated to "Mobile Telephone, Landline Companies,"
and that it is channel "JK".  It is sent in FM mode, and is a very
strong signal.

The channel names listed in this table also do not seem to make much
sense mnemonically, does anyone know what they mean?  The channels listed,
in order, are JL, YL, JP, YP, YJ, YK, JS, YS, YR, JK, and JR.
