like kwqvx fm or whatever?  Or is this just what they do on tv shows (like 555 telephone numbers)?

Throughout the world soon after the "transmitter" was first invented, there was a need to identify radio stations by letters (or as you say "initials").  For example, I happened to be licensed by the FCC (USA) as "WA2BLM".  The various licensing authorities devised a "call sign" "scheme" so that in case there was some sort of interference between this particular transmitter and a receiver, they could readily identify the particular transmitter.  Today, call signs are groups by what you call "initials" based upon country located and certain combinations of letters and numbers to signify the type of radio station (e.g. tv/radio versus public safety such as police, amateur radio a/k/a HAM Radio) etc.

You have to call the phone number that the end of the shows.  Then they will look at your case then they will call you.  It is not always local cases.

This one has people in the USA with listed (land line) phone numbers.\nThere are no cell phone directories on-line.

LA_Kinda_Guy beat me to this one.\n\nBack in the day, operators used 'exchanges'.  Each exchange was generally named after the area it covered.  As an example, my Grandparents used to live on Linda Drive in Amarillo, TX.  This was designated the 'Fleetwood' exchange due to its proximity to Fleetwood Park.  Apparently, these aren't all that far gone (in use as recently as the early 1960s), as I remember my Grandmother giving the phone number to the school I went to as 'Fleetwood-54987'.\n\nWhen the switchboards became automated, people began dialing the first two letters of the exchange as well as the number.  In the case of my Grandparents, their number became 355-4987.  If you look at the letters on a phone dial, F is on the 3, and L is on the 5.\n\nOn a humorous side-note, my Grandmother often grumbled about wishing it would go back to the old system due to the flood of wrong numbers we'd get anytime one of the local radio stations would have a call-in contest.  Their number was 359-4987, which sounded the same as my Grandparents number when said quickly.

I've tried to find this in for in the past from the phone companies, cell carries, etc without any luck.  Nor have I found any website.  But you could always call the number and ask...but you've already thought of and rejected that idea I imagine.

Old fashioned ....CALL THE  NUMBER AND ASK WHO IT IS!

I live in Kansas and have been getting them 5 or 6 an evening, mostly the same call.  I thought with the NoCall list we weren't supposed to get them.  They are particularly annoying as I have decided who I am voting for and will not be swayed by a recorded message.  \n\nBy the way, I hope all of YOU are registered and planning on picking up your friends and going out tomorrow and voting for the candidate of your choice!

I think you just answered your own question. The 106.9 part would be where you find it on your dial.

It's called Morse Code

I'm not sure, but I do wish that when they had multiple lines you could just call one number and it would be taken by whichever line is open for your contestant.  It's easier to hit redial, but then you wonder if the other numbers are free when the one you're dialing is busy.

maybe call them and ask

No, there are phone numbers for non-emergency calls.

If you do phone them 24 times in a row you are an absolute idiot.  You are tying up the telephones at the station.  If a real emergency occurs the people may not get through.  If you do keep phoning I do hope they find you and charge you.
