N2NXZ is  running  Opera  on  7038   [  dial  usb ] coded opera  frequency , using 
U3  Beacon  kit  at  100 mW   carrier power ,  [ corrected  to  50 mW average ] 
Being  reliably  spotted by KP3FT ! not reached EU  yet.. 

Beacon is running  at  100 % no  timer ,  local  copy  showing 

23:28   7038 N2NXZ de SWLNXZ Op2 -5 dB F:0% in Hilton,NY 1559.6 Hz
23:26   7038 N2NXZ de SWLNXZ Op2 -4 dB F:0% in Hilton,NY 1559.6 Hz
23:24   7038 N2NXZ de SWLNXZ Op2 -5 dB F:2% in Hilton,NY 1559.6 Hz

Good chance to catch a  genuine 50 mW station on 7 
Any  takers  from  his side of the  pond  ?

Thanks Andy, 
Yes ,  the  'old' system is  still  working nicely , after the  eme event ,  
JR re-worked the  decoder , appears to of gained a  few db's !

KC4SIT , running  5  watts  , at  - 1 dB s/n  could of been 1 mW !

KC4SIT KP3FT 40m OPERA 1534 miles 22:01:19

One pass decoder , produced a  interesting  propagation  plot , with a   ~ 1000:1  
change  in  signal  level, data  over a  6  hour  period, each spot is  a  
unique single pass. 

Captured  from the  data  base ,  the  s/n 
bar graph , originally  appeared  on the  ros  psk-reporter spots , useful
for a  quick  glance .. this  may  be  sinusoidal after a day or so ?
