[IRCA] Japan listening (was: Re: S. AZ TPs, Oct. 1)



--- Begin Message ---
The situation with the West Coast picking up Japan as sunset hits the western end of the path in Asia is analogous to trying to hear East Coast US/Canada stations from European sites at North American sunset.

US/Canada is likely best heard at sunset in Japan just as Europe / Africa / Middle East does best here in MA at sunset on this end.

A major reason in both cases is that a lot of potential interference from the opposite direction is still in daylight.

When I was in Ireland I did some looking for US and Canadian stations at the North America sunset times that European reception would be best back home.  A few of the biggies from Atlantic Canada, New England, and NY showed but general results were always better just before dawn on the eastern end of the path as the sky started to brighten over Ireland and the UK.  Daylight had reduced much of the mainland Europe interference.  Remember that this was 1977 and there was still a lorryload of big signals out of Germany, France, Scandinavia, etc. - much different now.

So, applying the same logic to TP's, I would suspect that near dawn on the West Coast is going to do better for hearing Japan rather than at Japan sunset.  Same reason as better North American reception in Ireland at dawn there: less interference from the opposite direction.

Thanks for posting the photo Gary-san (hi). As you can see...quite a lot
of daylight still. Just amazing reception in my book.

It's still pretty subtropical here right now, though there is a story about
sheltering from a typhoon at Taitosaki, so the weather is not always benign
at this time of year.

Satoshi-san and I looked south from Taitosaki, and compared it with the
Rockwork view....http://www3.telus.net/public/shallpat/4irca/IMG_9533a.jpg

You will note that the Pacific Ocean is on the "wrong side" of the photo,
at least by American standards hi. It seems to be a very worthwhile
modification in my opinion, at least where DX is concerned.

For example....at 0800UT 6 pips on 870kHz and "Nacional Informa" by man
...uh, uh. Argentina (thank you Mina-san for the heads up). I have not
heard Argentina from Victoria...one needs to go further away apparently.

best wishes,

Nick

Yes, I saw Fumiaki-san's photo of your reception of ESPN-Tijuana-1700 on the 5 inch "Frequent Flyer" FSL at Cape Taitosaki, Japan, with Satoshi-san as your "tuning instructor." I've taken the liberty of re-posting it at https://dreamcrafts.box.com/s/8feli5dacdkv19zdwslnp47pk32jfm5x

You and Satoshi-san seem very comfortable there at Cape Taitosaki.. no gale force winds or vicious rainstorm? :-) Wish that I could be there with you both-- and I'm sure that Tom does, also.
