It's E-skip! No wait it's a new tropo log! Confusing... 5/8/13

[crainbebo]

Just got myself a new tropo scatter log that I MISTAKEN FOR E-SKIP.

88.9 - KSWS Chehalis, WA; NPR news at 1903 PDT 5/8, and weather forecast for "east of the Cascades", leading into the CBC program "Q". Mistaken for E-skip since it was strengthening and fading. Still new! 94 mi.

94 miles? isn't that too close for tropo?

Here in the southern California area where I live, there are several stations that can be heard here pretty much all the time that are over 100 miles away. There's even one that's 212 miles away (105kW @ 905m, iirc) that is heard often enough that I'd have my doubts as to it being tropo.

 

[crainbebo]

Well, in Washington, tropo is almost a LUXURY. And KSWS is never heard here. If I receive Tropo it's usually Portland stations. I've only received Eugene, OR (250 mi) twice.

Tropo is really very scarce in western OR as well...on the central OR coast I once heard a very weak KDDS 99.3 from Elma, WA and in Sutherlin, OR, KLTW 95.7 Prineville, OR, with the latter with airplane scatter.

It's not common for an FM station to have a listenable signal at 94 miles, so yes, it can be considered tropo if it is heard when it usually can not be heard.

In this case, it would be tropo 'enhancement' which is not the same as tropo ducting.

When I used to live up north, there were some occasions where the New York FMs would come in from 80 miles away when they could never be heard at all during regular conditions.

That's tropo enhancement.

And remember too, pianoplayer88key, the stations that you can hear from a great distance on a regular basis probably have transmitters at significantly higher elevations relative to where you are.

We get the tropo enhancement effect quite often here in the Chicago area. Lots of times during the summer many Milwaukee FMs that are on adjacent frequencies to the local Chicago signals come in very well. These are stations that I can't hear under normal conditions.

Well, there was supposed to be tropo in W. WA late in the week according to this site:

So I'd say tropo it was. Supposed to be even more on Friday and Saturday.

Here in eastern Ontario, we must be getting that 'enhancement' on a regular basis. Does the relative positions of the St. Lawrence River (just to my south) and Lake Ontario (perhaps the Great Lakes in general, to my west) have a bearing on my reception of FM signals? Admittedly, I have an external antenna (AntennaCraft FM-6 on a 30 foot pole), but I normally get Toronto's CJRT 91.1 (@196miles) everyday, usually in the mornings, but sometimes all day, summer and winter.

Michigan has the same thing. Where I am, signals from Wisconsin are in often (some 24/7). Chicago occasionally makes an appearance.
