Nothing  like a  challenge 

 

After taking  great care  to  nominate  free  channels  to  Op last year,  slightly  more  rotund

systems  are  now consuming more  bandwidth 

 

JT65  users  kindly  providing  some in band  jamming  to  stress  test the  decode  engine 

Opera  pass  band  is  'under the  beacon switch' and flooded  with  pulses , of  similar

length  , OP1  sends  in 60  seconds , with a  expected  recovery  limit  of  -23 dB

 

As can be  seen, the  show go's on ,
