K2TQ: would seem, as John mentioned, to be very rare. Long path is not as uncommon as you might think. In fact it's "normal" mode for contacts on the other side of the auroral oval. See here for seve

Ayuh! For my FN55MF location in central Maine I calculate 68 minutes for JA3, 77 minutes for JA5, and 79 minutes for JA6 (I am assuming my software correctly identifies the JA call areas -- in any ca

interesting. It First it just depends on what you call "longpath". "Longpath" strongly implies the path is opposite the shortest path, or the longest possible straight path. We can be sure that isn'

Most of us use the term "long path" rather loosely. In my case when the JA's are strongest on my SE Beverage, I call it LP. That Beverage happens to be aimed at 135 degress. However, because of the b

Hi Tom and John, Here we go with our every few year semantic discussion. "Long path" has long been used (since ~1976 at least) to mean approximately 180 degrees... otherwise wouldn't it be called "lo

This is a lot like being a good used car salesman. If I work ZL3REX (and I have on more than one occasion) when he comes in via NW path, I can make a ho-hum contact sound much more significant by ca

Long path, short path, skewed path... Obviously, it is the ONLY path open at the time. Long Path is really an upper HF term. Using upper HF as an analogy, I really love it when working a pile-up on t

In my early days as a ham (50 years ago!) I was interested in the correct direction to point a beam antenna. The ARRL Antenna book provided a simple equation for computing the direction (and distance

short path. Well this changes everything. If the ARRL said it, it must be true. What tolerance is there on the 180 degrees? Is that to the nearest 0.1 degree? I've used a little less resolution in my

Hi Tom, You mean your "used car salesman" comment? :-) What about when they work A6? This is not a 180 degree path. Looks like about 135 degrees to me. (Received signal "SW" versus Great Circle beari
