Guess what Stefan meant is the center frequency of his transmission, HF-wise.
And that's less ubiquitous than this 'dial'-thing, because the combination of the 'dial frequency' and 'audio frequency' is irrelevant. Only the sum of both is relevant.

If jt9  is a  multi tone  (mfsk)  system , as is wspr  , then  which   tone  are you  declaring  the  frequency of  ?
better to  use the  dial  convention ,
 
Then  everyone  has the  same (suppressed) carrier frequency and what  ever audio  offset  will  be  unified

Hi Mauro,

I'm on 137.42 kHz (i always tell the TX frequency), yes JT9-2.

Spiros, did you decode the 21:08 and 21:12 transmissions? Is there someone else watching?

Thanks Spiros,

That looks consistent, you're loosing no single transmission.
The reports look reasonable as well.
