After playing in the ARRL DX contest in the early morning hours, it looks to me that what is *really* needed is a small DX window somewhere in the 15 kHz JA segment 1810-1825. Heck, it could even be less than 5 kHz wide. >From my QTH in the central USA, I could copy JAs who were working NA stations; and some JAs spotted NA stations in the cluster. But 1810-1825 was wall-to-wall NA stations calling CQ. What are the chances of such a DX window making it into the rules? Maybe in a future Stew? 73, Mike www.w0btu.com On Tue, Dec 2, 2014 at 3:52 AM, Petr Ourednik <[email protected]> wrote: > the split JA operation schema for decades ago was: > JA TX > 1907.5 - 1912.5kHz and listen for rest or worls in between > 1820 - 1825kHz. > This "JA window" 1907.5 - 1912.5kHz has been not used in contests from > 1999 by JARL > because the band was too narrow.
