I believe 3576 - 3580 in the region 1 & 2 band plan is allocated to CW operation and is not for narrow band modes like JT65 & JT9.
In region 3 the current usage and the proposed options all seem to be in an all mode section and there is no specific non-CW narrow bands section so there doesn't seem to be an issue there. > And if we don't coordinate such a change with other JT65 software packages > all we do is confuse a lot of people don't we? True but bands plans are there for a reason. Operators will go where the DX is in general. WSJT-X doesn't mandate the operating dial frequencies, in v1.4 you can change the default dial frequencies pretty easily. > > Mike W9MDB 73 Bill G4WJS. > > -----Original Message----- > From: Bill Somerville [mailto:[email protected]] > Sent: Thursday, November 13, 2014 10:55 AM1 > To: [email protected] > Subject: Re: [wsjt-devel] 80 m frequency for JT65 and JT9 > > On 13/11/2014 16:36, Joe Taylor wrote: >> Hi all, > Hi Joe, >> I have been advised that the default 80-meter frequency compiled into >> WSJT-X, 3.576 MHz, is not compliant with the current IARU >> recommendation for region 1 and 2.
