Good morning George,

 

I posted a few things I am working on a couple of days ago.   This is one of 
them and I believe there is room for a single character in the CQ message to 
indicate this and a few other operational items.   Here were my comments on 
what I propose to develop…

Might look like:

Subject: [wsjt-devel] MSK144 Timing Flag?

 

Is there room in the MSK144 protocol to include a “duration” flag, indicating 
the sequence length selected by the transmitting station? In meteor scatter 
use, length isn’t usually obvious by listening, and mismatched sequence times 
could create undesired interference and longer times to complete.

 

I would suspect that MSK144 short sequences will find use during Es season, 
too. Having the software able to match sequences would be handy.
