[K3PZN-List] MUF (is rising)

[wa3mej at comcast.net]

Curt, 

  Dont tell that to my log and radio because I work stations above the MUF pretty routinely. By definition the MUF is a percentage of Fcrit (the critical frequency where the signal is not reflected) you can work stations between the MUF and Fcrit quite often.  You cant use the propagation models as a guide of absolute propagation.. they use a running average of the solar flux in the program and most of us just plug in the Solar flux and run with it... this is an incorrect use of the data.  Several years ago I worked in a propagation lab and there was often an argument over how the MUF was calculated and how to use the data.  Remember to old axiom... be rewards require big risk.. dont be afraid to take a chance on what might be out there because someone else says it wont be there

One cannot actually make contacts above the MUF (because that is the maximum usable frequency) - but I know what you mean.  
  
MUF is path sensitive - and calculations from measurable solar data may not accurately compute what the MUF really is.  Yes with my puny station I have worked stations way out in the Pacific on 10/12/15 meters when literally there are no other signals on the band.  (of course those of us who engage in CW enjoy these sometimes very weak signal contacts, not that they won't work also in some digital modes).  
  
One of my co-workers mentioned on repeater this morning some short duration openings to Eu (he also has a puny station) on 10m, and likely as we get deeper toward fall (if the solar flux continues to stay > 100) we should have plenty of 10m action.

NIce story Curt.  thanks.. by the way dont be afraid to operate above the MUF.  THis is where I find most of my greatest DX. Often it is because others dont think that band is open so no one goes there and you can work some really nice station without the pressure of a pileup.
