On JA7AO's BBS, JA7NI said at 09:40Z, April-05th;
"Though I was waiting for VE1ZZ today, it's impossible to hear him,
because the jamming signals just like last years' niose from BY has
been coming from 09:00Z and was 1660-1960khz wide with S9 over.
So I reported this thing to JARL."
Then, I watched 160M at 11:30Z and there was S9+20db between 1800-1870
and was S9 from 1700 to 1940kHz with my inv vee dipole at 30mtrs high.
It's TOO BAD, but I hope I could to get VU4AN on 160 later this month.
I did update these sound files of jamming signals at:
