92PRO-FM Walks All Over Rock92/Greensboro NC - Skywave Skip for 15 Mins.

A

amfmradio1

Sunday afternoon.

One of the longest DX I've ever listened to.

700+ miles.

Listening @the Charlotte-Douglas Int'l Airport.

Know that this happens in the Summer - also a lot between WLW/New Orleans & WCBS880
 
Lots of E-Skip shortly before 8 PM last night in New London CT area. Mostly Georgia & Northern Florida including 101.1 WAFT in Valdosta (GA) and 94.3 WNFB out of Lake City FL

It is always a trip when E-skip comes to town! My experience seems like the "E"s generally have a range of between 700 to 1,400 miles, with around 1,200 miles maybe the sweet spot. I usually seem to have best luck afternoons and also around sunset. Often the entire FM dial seems to become awful noisy and then you find that most of the presets on your radio "changed formats" (Hit the rock button and hear classical instead). Most of my catches appear to be from Atlanta to Orlando and swing south west into the Muscle Shoals, Alabama regions. I have also heard Indianapolis. I don't recall ever getting E skip from Canada or northern United States, but I'm sure some people have received those areas. I've always wondered if there was a reciprocal effect (RI stations skipping south at the same time) and your post verifies that! One good thing about the Insignia HD-02 is the ability to record 15 minutes of airchecks on those occasions.

FM detectors in an ordinary radio have a specification called "capture ratio" of about 3 dB. This means that if one signal is at least double in strength of another co-channel signal, the more powerful signal is "captured" by the detector. The weaker signal is then totally ignored and does not adversely affect the quality of the stronger signal. This indicates that the strength of the E-skipped signal is at least TWICE as powerful as the local signal it is replacing! It seems like the "square law" rule of physics is suspended (it isn't)!

One question I ask is: Has anyone had opportunity to see if the HD signals also make the journey? I know the analog FM stereo signals are OK, haven't had the chance to check if their HD 1, 2, and 3s are.

It was E-skip, heard some great Georgia radio in CT!

This is probably true, however GA -> RI is also possible with tropo. I have received GA from here (MA) during tropo along with SC. Likewise, I have had Atlanta via e-skip as recent as 2 months ago.

I've received HD signals in E Skip many times. Sometimes I'll get it around the sides of stations locally that aren't running it, like WLYF and WPOI when WWBB had theirs off, and WHQT around WWLI.

Wow! Thank you for the great info!

It doesn't hurt that many of the stations that skip in are full signals and come off some very tall sticks or big hills in the southern Appalachains. Go to any coastal city in the south and you'll hear lots of stations out of the Piedmont. The way the Earth drops off is great for FM propogation. Then, if you have fronts moving up the coast in the warmer months those stations ride.
