Hi Marcus, Joe & LF,

Joe,
 
thanks for the info. That must have been a= round sunset on your side... the signal then disappeared for a while a= nd became again visible after midnight UT.
 
Coherent keying would be beneficial as it = generates a sharp central line in the spectrum which aids detection of = ;below-noise QRSS or Opera signals. The source doesn't need to be refe= renced to GPS or similar, any stable oscillator will suffice as long as it = is not interrupted by the keying. If you are now using a divider to dr= ive the PA you would need to let the divider continue during key-up, a= nd gate one of the subsequent driver stages instead.
 
It is also possible to generate coherent F= SK or DFCW but this requires careful adjustment of the symbol timing and fr= equncy shift so that df * dt is an integer number (as in WSPR or WSJT-X).

Dear Markus, Group.

Thank-you for the report.  Yes, VO1NA is on the air however there is s= till
work needed towards achieving phase coherence keying!  The TX is a 100=
watt class E: an IRFP260N driven by a TC4427.

Hopefully the Decca will be back in service soon.
