The pattern reference maps on the site
http://radio-timetraveller.blogspot.com/ have been a great source of
information. However, lately, the pages show up with a mask that says FOR
DEVELOPMENT PURPOSES ONLY...has anyone else noticed this?

...Do you know of any other sources of maps that show all the stations on
each frequency? The NRC pattern book is great, but I'm looking for
something digital, for the classes I'm teaching.

Any thoughts are welcome!


Cheers!

The files for the maps are zip files. They are difficult or impossible to use on many tablets and cell phones. I found a website that has them.

Poipu, Hawaii Ultralight TP's for 11-8  View Printable Version 
Friday, November 09 2018

Thanks to Craig and Walt for their earlier comments, and yes, the exotic DX results of this trip have far exceeded all expectations for a 5 inch FSL antenna brought to Hawaii in hand carry luggage. During the last session the 1000 kW 693-Bangladesh finally broke through heavy 690-KHNR splatter, while new mystery language stations showed up on 675 (apparent Taiwanese, according to Hiroyuki) and 954 (yet to be assessed by the Real DX experts). 927 also apparently had a Southeast language lady showing up under China, and 1575 may have had Radio Farda around 1630. Once again 918-Cambodia rose up to S9 around 1635, and was at good strength right up until its sign off at 1703 https://dreamcrafts.box.com/s/dtthxs76wa1w7n0xer9kxcttpzmdwwfc

Probably the greatest challenge of the trip was to keep checking 693 (despite the nasty 690-KHNR splatter) for a possible appearance of 693-Bangladesh, even though the 10 kw Honolulu blaster is only a short distance away across salt water. 693-JOAB could make it through for the NHK2 music box sign-off despite the splatter, and I figured that Bangladesh could do it as well. Finally near the end of the last session at 1639 some 693 audio broke through, and I was lucky to record the same Bangladesh announcer that was heard on multiple Cook Island MP3's, speaking in the same apparent language. This was my last major exotic target except for India, which may well show up in the many recordings made on previous days (as 657-AIR did after the Cook Island trip). As of now, definite identification has been made of exotic stations in Oman, Bangladesh, Myanmar, Cambodia and Vietnam.

So what is the overall assessment of Hawaii DXing propagation? It is far and away more enhanced and diverse than any west coast DXer can possibly imagine, and a single session can provide exotic results far greater than an entire year of ocean coast DXing in the Northwest. The forward location of Kauai allows the band to stay open past 1700 UTC, which is a phenomenal advantage in going after stations in central Asia, and even the Middle East. Hawaii does have an excessive number of local stations, but a DXer can usually work around their splatter by either nulling them out (with FSL's) or by going to the other side of the island to put the local volcanic cliff to work. The location of Poipu Beach at the extreme southeast tip of the island proved to be very fortunate-- as hoped for, there was excellent propagation to East Asia on all 5 days, and good propagation to North and South America on most days. Some huge DU signals were recorded from ANZ, Tonga, Samoa, Kiribati and Tuvalu on most days, while 702-BBC in Oman actually showed up every day of the week. For those in the Pacific Northwest who are looking for a new level of DXing excitement, the Aloha State is definitely THE place to make it happen!


73 and Good DX,

Gary DeBock (DXing at Poipu Beach, Hawaii from Nov. 2-8)
