[TOEC] [CCF] SAC CW 2012 RESULTS PUBLISHED

[Mikael Rytky]

So, nobody knows his/her accurate transmitter frequency and nobody can report what frequency we thougt we were using with better resolution than 
1 kHz through the log?

If I'm 499 Hz off without knowing it (log will say I was spot on), I cant do anything about it. I just get a penalty afterwards....
