July Rockwork 4 DXpedition-- Top Ten Signals from the South Pacific


Gary DeBock
 

The ocean cliff DXpedition conducted this month from the Rockwork 4 Highway 101 turnoff (near Manzanita, Oregon) from July 5-11 featured an international DXing group, with most of the members coming from other countries. We were especially honored to welcome the noted Japanese DXers Hiroo Nakagawa and Satoshi Miyauchi, who certainly had full exposure to the thrills of ocean cliff DXing (in more ways than one).    
As is typical at this ocean cliff site South Pacific propagation was seriously slanted toward New Zealand, although we had several good Australian signals, an almost daily blowtorch signal from 738-Tahiti and occasional reception of 1017-Tonga. The recordings below were all made on my Ultralight radio + FSL antenna systems, and represent the ten strongest DU signals observed over the 7-session trip. Both Tom and Nick were at the cliff for 3 sessions (July 9-11), while the Japanese were with us on July 10th and 11th. As most of you know by now, the July 10th session was notable for vicious rain and wind, making our antenna setup and DXing session a legendary struggle against the weather. Trying hard to adjust during their first session at the cliff, the Japanese probably wondered if a tsunami would hit us next.
 
531   PI   (Auckland, NZ, 5 kW)   Samoan broadcaster dominated on all 7 days with good signals, although 4KZ and More FM did manage to get through at times. This good-level Samoan female speech on 7-5 was typical
 
603   Radio Waatea   (Auckland, NZ, 5 kW)   Usually the strongest of the Maori network, this vibrant regular plays a mix of Maori and Motown music. Its strongest signal was on the last day (7-11) at 1218
 
675   RNZ National   (Christchurch, NZ, 10 kW)   The new kingpin of RNZ network transoceanic strength (after the demise of 567's old tower), this relay consistently outperformed its 50 kW parallel. This signal at 1257 on 7-8 was typical
 
702   2BL   (Sydney, Australia, 50 kW)   Easily pushing 702-Magic aside whenever it showed up, this Oz big gun was the dominant station on both 7-7 and 7-10. The interview format was much different from Magic's oldie music
 
702   Magic   (Auckland, NZ, 10 kW)   Capable of blistering signals when Kiwi propagation was enhanced, this oldie music broadcaster was the only DU on the frequency on 5 of 7 days 
 
738   Radio Polynesie   (Mahina, Tahiti, 20 kW)   A real blowtorch on most days, this French-language signal at 1233 on 7-9 was the strongest DU recording made during the trip, and seriously tested the crunch resistance of my Ultralight radio
 
765   Radio Kahungunu   (Napier-Hastings, NZ, 2.5 kW)   Once again this low-powered Maori network station acted very much like a Kiwi big gun throughout the week. Maori and Motown music // 603 is the norm, as in this recording at 1215 on 7-8
 
774   3LO   (Melbourne, Australia, 50 kW)   LR Network big gun was strong at 1222 on 7-5 but missing in action under Radio Sport on most days
 
1035   Newstalk ZB   (Wellington, NZ, 20 kW)   The flagship relay of this talk radio network had potent signals on most mornings, including this discussion concerning NZ real estate at 1222 on 7-8
 
1386   Radio Tarana   (Auckland, NZ, 10 kW)   Hindu music broadcaster pounded in when Kiwi propagation was enhanced (as in this recording at 1246 on 7-6), otherwise got lost in splatter
 
Of course many other DU signals were heard during the DXpedition, and a full report will be drafted after all of the recordings are reviewed.
 
73 and Good DX,
