Man is the skip coming in today...ON FM

[raydioheadfm]

Out here in the East Bay/Dublin area...tropospheric ducting a major way and it's all from the southwest, centered in
New Mexico.  This was what I scored today from 2:45 til about 3:30pm

105.9  KSEL   Clovis, New Mexico 

92.7   KKBS   Guymon, Oklahoma  (just over the New Mexico border, 250 mi from Santa Fe)  Right on top of Energy 92.7

97.3  KKSS   Albuquerque, New Mexico  Right on top of Alice@97.3

94.5  KKOR    Gallop, New Mexico    Right on top of 94.5, K-BAY

Pretty interesting out there....

Wow!  Am I understanding that you got these stations "over-the-air" on your radio?  If so, I've never heard of any FM signal travelling that far??

[raydioheadfm]

Yes, this is a not uncommon experience, although most people are familiar with receiving distant AM signals at night.  Perhaps one of the
engineering types could explain why this happens on FM..and during the day.  It was crazy...they were all over the dial.  Although, I have no
idea if someone, say in San Jose, was hearing what I was hearing....

It's called "ducting" because the atmosphere acts like a duct and channels some signals long distances.  This happens most often when the area between the transmitter and receiver has an inversion layer (the temperature is higher in the atmosphere than it is near the ground), and most often when the air is moist between transmitter and receiver. 

This is most likely to happen in late spring and early fall when the atmosphere is cooling between the station and the receiver (around sunset at the station).  If you think it's unusual to get FM and TV stations from 500 miles away, try listening to CB radio where mere 5 watt signals are likely to carry 2000 to 3000 miles.

Wow. Does anybody DX any more? I used to sit up all night (when I was twelve) listening to WWL/New Orleans, KGYN/Guymon OK, KRVN/Lexington NE, KOB/Albuquerque, KTWO/Casper WY and a myriad of other AM stations all across the fruited plain.

Heck, it used to be fun trying to hear a station on every frequency across the dial at night -- you knew back then (the '60s and '70s) that if you heard something in Spanish, odds were that you'd caught Mexico (or Cuba, or Costa Rica). Now? Not so much.

It used to be a big thing "catching" a little pea-shooter in Kansas, or every station in California, or something exotic, like Japan or Hawaii. Nowadays, I don't think it's even a sport anymore. Hearing "Coast To Coast AM" on 100 spots across the dial kind of sucks the joy out of it.

Hey Boss Radio..

Our station KNUU Las Vegas, has DXer's in Finland. (guess there's not much to do there)

These guys have clubs that own elaborate antenna setups to DX AM signals from all over the world they have e-mailed me audio of myself as picked up over the air.

They know we stream at 970knuu.com but the kick for them is hearing it over the air. One guy even sent me a picture of himself at his listening station.

Yeah, I used to be a DXer too...until George Noory came along.
