[Lowfer] WSPR for Dec.14-15

[JUAN A. GRANADOS]

Hi Eric!

  2012-12-15 21:52 	 WG2XJM 	 0.475673 	 -26 	 0 	 EN91wr 	 20 
  WF2XXQ 	 EL95tq 	 1784 	 181


Great decode this early in the afternoon.

I have moved my transmit freq to the very upper limit of the band to 
stay away from the bigger signals in the East. Last night I decoded all 
the stations that were transmitting, but in spite of the excellent 
conditions my weak signal was not decoded most of the night (like it 
usually is), although there were many listeners...

I hope it will be better this evening.

Regards and 73
