Hello Luis,


I would't care about that 7km, that's little more than 10 wavelengt= hs ;-)

Also compared to the distance between us (about 1500km) it can be n= eglected.

Hi Rik
 
Pity ! Could not receive anybody here. And conditions were n= ot bad at all. I was spotting LA2XPA in WPSR at that time
 
I have been monitoring JT9 for some time now and can recall = receiving you and other stations
Unfortunately Eric, ON5TA, got a problem in his PA and is QR= P now
 
Anyway the downconverter is online and if there is any other= chance we can try QSO
