DGPS Logs 20-21 Dec 2016
« on: December 21, 2016, 1314 UTC »
An interesting change in propagation. The night before I had 22 logs from Panama, the night before that 367. Last night, 4211.

Speaking of Panama, I have not logged Gatun on 307 kHz since the end of August. It used to put in a respectable signal here, hundreds of decodes a night, at least one night over 1K.

Recently I have been looking at this for propagation clues.

http://dk0wcy.de/magnetogram/

As opposed to other charts, this is a fine grain look at geomagnetic conditions over the last 24 hours, and gives a better idea of what things are like now, at least in Kiel.

Do any particular values or patterns on those charts appear to correlate with LW/MW propagation?

When the NS component is flat and near 1, I note good props.  To which direction?  It varies, but I have been able to see that props from the North, generally Canada, become depressed when the NS component changes markedly.  I have been able to note prop changes in overnite recordings which seem to jive with this plot.

I have been using this as a guide which MIGHT give an indication as to where to DX during live sessions.  If the NS component is low and well behaved, I will go after stubborn targets to the North (the Maritimes to AB).  Otherwise I will go after targets to the South (TX to the Carolinas).

In all cases, you still have to play the game, no matter how crappy things look. 

An interesting use of the short term plot is finding that time during which conditions flip; props can be very interesting then, with favored directions becoming quite unpredictable.

I have made no correlations with the EW component.

LF propagation is so fickle and interesting.  It's fascinating to see how quickly an opening to a very particular area can occur. 

One can only imagine what's going on up there.

Thanks for the info. I've tried make correlations between DGPS results and the varies indices, but it is difficult to find any hard and fast rules. As you noted, propagation down there is very fickle and changes quickly. A DX DGPS station will often appear for a short period of time, with a burst of decodes, and then disappear. Some of this is due to the mix of stations on a given frequency, in order to hear the DX target, it has to propagate to your QTH, while the normally dominant station(s) must not.
