you list two stations at one time (1355), how can you be sure what you
got ?

He said it was in parallel with 1134...

True, I did have 972 in parallel with 1134, therefore the two logs with the
same times. However, Captain could have rightly asked about my other logs...
how do I know I had JOIB Hokkaido on 747, for instance? Well, I'm basing
these loggings on the following:

--14 years of regular DXing of trans-Pacific mediumwave signals, including
3-4 coastal DXpeditions per year, and knowledge of TP DX propagation
characteristics
--I've heard each of these Japanese stations many times before, and I'm
familiar with their pattern and style
--Over the years I've ID'd them through parallels and occasional NHK network
and/or local IDs
--I use a very reliable source of TP MW information, the Pacific Asian Log,
and watch for station changes and updates through forums and groups like the
MWOZ Yahoogroup, IRCA, HCDX, etc.
--I share & receive current station tips with experienced foreign MW DXers
like Nick Hall-Patch, John Bryant, Patrick Martin, Bruce Portzer
(author/compiler of the Pacific Asian Log) etc.

Many 9-kHz frequencies for the Asia-Pacific region only have one Japanese
station on the air, and no other stations around the region with Japanese
language programming. Of course, it's *possible* for a new station to come
along which fits the pattern, language, music, and other clues of the usual
occupant of the frequency, and even the "experts" can be fooled. The
text-book approach is to never claim a station is heard unless you hear a
definite ID. However, common sense and experience serves well for 99.9% of
the situations.

If you briefly tune across 5975 kHz in the early North American evenings and
hear rugby match scores read by a Brit-accented announcer, do you doubt that
you've heard the BBC relay from Antigua? They've been a regular on that
frequency and timeslot for so many years they practically own 5975. The
major mediumwave outlets in Japan, China, Australia, etc. rarely change
frequencies, and I think it's similar with the Europeans-- that's why you'll
see so many of Mark Connelly's European/Latin/African MW loggings list a
definite callsign and/or station name, but no actual ID reported. He knows
the regular occupants of each channel "like the back of his hand", as the
saying goes.

So... this is my reasoning for reporting mediumwave stations. If I *do* have
any doubts about what I'm hearing, I have no problem calling a catch
"presumed", "probable", "tentative", or "unidentified". The same
investigative reasoning goes for my tropical band loggings, also.

BTW, Hokkaido is the region (island) of the Japanese station on 747; I
should have written Sapporo which is the studio/transmitter location.
