Thanks Joe for fabulous software. In WSJT, in wsjt.py, can you define "idWarn=-1" to stop the error message?
In WsjtMod/options.py can we default, that the sending callsign be always sent? And, Downunder here, we use "/" to "attach" the report to the callsign as in: VK7XX/26 VK2ZIW 26 VK7XX/R26 VK2ZIW VK7XX/RRR VK2ZIW VK7XX/73 VK2ZIW Such that when a garbled message via MS is received, we can sort it out. Lots - a - fun, on 6m, 0700 to 0800 local. 80 (more anodes than a 73) Alan VK2ZIW On Fri, 07 Aug 2015 16:28:19 -0400, Joe Taylor wrote > Several people have asked for an update on development of the "Fast > modes" in WSJT and WSJT-X.
