[HCARC] Propagation

With a beam you can experience back-scatter when the ionosphere is nice and
strong.  Both stations beam toward the same direction and hear each other,
but can't hear each other when they point at each other.

Sometimes you can hear long path and short path at the same time on a
station.  There is a quite noticeable delay or echo sound.

  My bet is still on "Long Path".  It's amazing the distance that given the 

  right ionospheric (how about that big word, radio fans??)  conditions your


  signal can go easily all the way around the earth.  Talking with Terry 

  Hipskind a couple of weeks ago he had a QSO on PSK31 (still HF
propagation) 

  to Amsterdam Island (look for Amsterdam Island in the middle of the
southern 

  Indian Ocean halfway between Australia and Africa, approximately 1/2 the
way 

  around the earth) using the normal PSK31 wattage of around 20 watts. 

  Comparatively 15-20 watts is not much signal to go so far and still be 

  readable - granted it is a computer doing the hearing, but 12,500 miles is


  12,500 miles, regardless of how you cut it.

  Hank,

 

  Your response makes me think I should rephrase my question. That would be,


  what conditions should I look for in the future when I have a qso with a 

  station to the east of me, the east coast and/or Europe. It will be easier


  to make note of conditions at that time than trying to recreate the past. 

  After all, in ham radio expect the unexpected. I know I will have similar 

  qsos when I return to my northern qth.

 

  Concerning my absence this morning. The XYL gets the car on Wednesday 

  mornings so I am left to my motorcycle. Just wasn't up to suiting up for 

  this morning's cool temperature so I had to breakfast alone (I know, I can


  hear one big sigh out there).

 

  73,

 

  Jerry

  Jerry,

 

  I wonder if the "giant reflector" behind you is not allowing you to
maximize 

  Ionospheric reflection? If the atmospheric conditions were just right? 

  Another part of the puzzle would be to look at the weather and atmospheric


  conditions, both Chicago and received station, for each of the events.

 

  Missed you at coffee this morning.

 

  Regards

  Hank
