Hello Luis,


maybe your big building is good for transmitting but not so good fo= r receiving due to all the local noise. Setting up a remote RX at= a quiet location could do miracles.

In JT9-1 mode signals can be copied down to -26dB and you peaked &#= 43;1dB, so these was a margin up to 27dB (500 x power !!!).

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
