Ive pointed Hiroshi to all the well known sites, but I know (and rememb= er) how daunting it must be/seem, and I think Ed has also been doing the sam= e, though that might have been another JA.
 
Still, Hiroshi's  transmitting on 136.9 CW and Ive left my grabber on t= here on slow speed to see if I can detect anything after dusk tonight -= its a +-2000Kms all water path save Korea and a bumpy bit as it crosse= s Japan -  as hes on the East Coast, and yes Ill have the volume up as=20= well...
