I should have noted that the current guard band appears correct to me given the WSPR frequencies quoted on WSPRnet and other sources. The difference being down to the bandwidth of a JT65 signal plus a 20Hz error margin. I.e.
10139900 + 180 +20 = 10140100 and 10140320 - 20 = 10140300 > > There is no way to disable the guard band without changing the source code. > > Comments?
