Hi Milt, It sure helps me. I don't make any bones about new to 160. My antenna and my transmitter have been giving me a lot of grief so I have had only a few QSOs...maybe a couple dozen. I am not a "seasoned professional" on top band. I'm just an amateur. My license even says so (evil grin). So far when I have tried to get on the air, "reasonable amateur practice" has kept me out of serious trouble. Lots of listening and a query before using a "vacant" frequency. I know what a pileup sounds like so even if I can't hear the DX I know (s)he is around.
It's helpful when in Rome to know what the Romans do. 73, Bill KU8H On Wed, 2012-12-05 at 15:55 -0700, Milt -- N5IA wrote: > Bill, > > As Peter has responded, there are two JA windows; 1810-1825 and > 1907.7-1912.5 . > > Until a few years ago the JA hams only had the upper 1907.7-1912.5 > allocation.
