[IRCA] Oregon Cliff (Cape Perpetua) Ultralight TP's and DU's for 8-19
Hello, Four wild days of cliff-side DXing on Oregon's Cape Perpetua finished up in typical fashion yesterday morning as both Asiatic TP's and DU's showed up in strength, causing snarling mixes on several frequencies. The Russian longwaves started off the fun around 1216 with 279-Radio Rossii testing the crunch resistance of my PL-380, pegging the S/N readout for the duration of a recording. This was followed by 1566-HLAZ at 1243 with a blistering signal-- far and away the strongest that I've ever heard them in six years of DXing. 1593-CNR1 also moved in with good signals around 1238, following the high-band trend that Dennis noted. But on the cliff, the Asian TP's had no trouble showing up from 531 to 1593 kHz. The Japanese big guns moved in with serious force early on with strong signals on 594, 693, 747, 774 and 828, along with some fair signals on NHK1 synchro frequencies like 603 and 639. During the middle of sunrise enhancement (around 1300) the DU regulars started to move in with some strength, causing snarls and mixes with the Japanese on certain frequencies (531, 603, 639 and 891). The NHK big guns stuck around for almost all of sunrise enhancement, although the Aussie big guns 576-2RN and 774-3LO managed some very potent signals themselves after 1330 (with 576-2RN pegging the PL-380 S/N with an awesome signal of its own at 1335). Several DU's were the sole survivors after the Asians faded around 1400, with 639-2HC and 891-5AN still strong enough for easy copy around 1405. The Cape Perpetua cliff propagation during this 4-day DXpedition was really wacky and wild, with more TP and DU monster signals (and snarling mixes) than I've ever heard in any ocean coast trip. The Highway 101 turnoff is located on a curving cliff, which apparently provides huge amplification for transoceanic signals from either Asia or the South Pacific, depending upon which area has the propagation edge. Sometimes (like during the past 2 days) both areas have good propagation-- leading to wild mixes of Asian and South Pacific signals on several frequencies. 279 Radio Rossii Blistering signal at 1216 with Russian YL speech-- the strongest Longwave TP received during the trip (or ever) http://www.mediafire.com/listen/jmxbchc3td4q5hd/279-R.Rossii-1216z081913PL380.MP3 576 2RN Sydney, Australia, 50 kW Another monster signal at 1335, pegging the PL-380 S/N at 25 for the duration of the MP3 http://www.mediafire.com/listen/qz6x4g6wiit264e/576-2RN-1335z081913PL380.MP3 756 RNZ Auckland, New Zealand Usually not one of the better RNZ performers, it did manage this fairly decent signal at 1338 http://www.mediafire.com/listen/8mstmtdyb3p485i/756-RNZ-1338z081913PL380.MP3 774 3LO Melbourne, Australia, 50 kW Punching through Seattle splatter with female-voiced local ID at 1344 ("You're listening to , 774 ABC, Melbourne") http://www.mediafire.com/listen/hjdm4l7w139pjvh/774-3LO-1344z081913PL380.MP3 828 JOBB Osaka, Japan, 300 kW Very strong with Japanese weather report at 1315 http://www.mediafire.com/listen/3ff0r2y214lqie1/828-JOBB-1315z081913PL380.MP3 1008 JONR Osaka, Japan, 50 kW Temporarily dominant over Newstalk ZB (and domestic splatter) at 1330 http://www.mediafire.com/listen/1md9s7kmuts82h9/1008-JONR-1330z081913PL380.MP3 1566 HLAZ Jeju, S.

It's hard to believe that we were listening on the same planet Gary, let alone the same coast, though admittedly, I'm quite a way from the open Pacific here.

Hi Nick, <<< It's hard to believe that we were listening on the same planet Gary, let alone the same coast, though admittedly, I'm quite a way from the open Pacific here. As I said yesterday, that morning was pretty much the biggest stinker this summer here. >>> Yes, it seems that a more southerly location can often make all the difference in TP propagation. Dennis was DXing right in between us, and he reported some of what showed up at the Cliff yesterday, including the awesome signal from 1566-HLAZ. The cliffs like Rockwork and Cape Perpetua really do seem to generate their own unique twists in DU and TP propagation, though, even when compared to adjacent sea level beaches. That's probably why the results often seem so bizarre and wacky. 73, Gary DeBock (back in the DU-dead zone of Puyallup, WA) -Original Message- From: Nick Hall-Patch To: Mailing list for the International Radio Club of America Sent: Tue, Aug 20, 2013 6:43 am Subject: Re: [IRCA] Oregon Cliff (Cape Perpetua) Ultralight TP's and DU's for 8-19 It's hard to believe that we were listening on the same planet Gary, let alone the same coast, though admittedly, I'm quite a way from the open Pacific here.

As I said yesterday, that morning was pretty much the biggest stinker this summer here. best wishes, Nick >> My home locations have always been a fairly easy commute to TA-capable shore sites: e.g. Arlington, MA: 7 miles (11 km) to Revere Beach Sudbury, MA: 20 miles (32 km) to Boston waterfront Billerica, MA: 15 miles (24 km) to Salem / Marblehead South Yarmouth, MA: 12 miles (19 km) to Chatham / Orleans These are air distances for typical 50-75 degree Euro bearings. Road distances to DXpedition sites are typically a bit more if only because the shore is heavily developed and only offers certain areas useful for DXing from the car. In my present case (S. Yarmouth), because of the contour of the shore, the drive to a usable site is actually shorter than the 50-75 degree bearing air distance house-to-shore. In all cases, the differences between home sites and the coastal DXpedition sites are HUGE. Some stations were routinely 30-40 dB stronger at the Granite Pier site in Rockport, MA versus less than an hour's drive away at Billerica. The 1544 (later 1550) Algerian clandestine station was one station which consistently exhibited this whopping difference. Long term comparisons were easy to make since I could use the same in-car receiver and rooftop antenna.

There are numerous stations that cannot be heard at home sites on big antennas yet can be heard from time to time on a 2m by 2m car-roof loop at nearby beach sites. If a station arrives at a higher angle, the location characteristics are less critical and your inland signal may only be 15 to 20 dB degraded from what is noted at the shore.

V-Soft shows 660 WFAN (NYC) running 6.24 mV/m at Falmouth, MA 02543 (shore) and 0.45 mV/m at South Dennis, MA 02660 (about 15 miles / 24 km inland for 255 degree bearing towards station). In decibels, this equates to a 23 dB drop - and that's for a LOW-band station. A high-band station would show an even greater overland signal deterioration. The V-Soft groundwave variations don't look too different from what is routinely observed with low-angle long-haul DX skip.

Re: [IRCA] Oregon Cliff (Cape Perpetua) Ultralight TP's and DU's for 8-19
Yours are really valid points Mark. Inland definitely can mean considerably poorer signal strengths, and I would not be surprised if my "usual" sunrise enhancements on TP signals are due to high arrival angles of the incoming wave front (see my QEX article of some years ago for that very hypothesis). I certainly didn't expect anything like Gary's signal levels, but, as Gary pointed out, Dennis, who is considerably further inland than I also heard a couple of Asiatics quite well, and I heard practically nothing, even carriers. In this case, it may have been that the farther north path to my location from Asia had some attenuation on it that didn't affect the more southerly paths, though conditions were not particularly auroral. Generally this summer, Dennis and I have heard similar Asiatics on any given morning, on the rare mornings that Asiatics were to be heard, though he does better on the longwave Russians, and indeed on MW Asians as fall approaches. Thanks for your thoughts. Propagation continues to be mysterious! best wishes, Nick At 21:34 20-08-13, you wrote: << It's hard to believe that we were listening on the same planet Gary, let alone the same coast, though admittedly, I'm quite a way from the open Pacific here.

Hi Derek, The 4 days spent at the Cape Perpetua cliff last week provided the wackiest and wildest DU-DXing sessions that I've ever experienced in six years of TP-chasing. Every morning had a new propagation twist to it-- almost like the Cliff was never going to let you discover its propagation secrets.

Hi KAZ, <<< Have any of you compared ocean cliff reception to adjacent beach reception when using the EXACT same setup? ie...ULR and 12" FSL on the cliff vs same make ULR and a 12" FSL on a nearby beach? >>> Since the new 12" FSL models (both tunable and broadband) were only designed and built last winter, Neil, we haven't yet had time to run an exact test like you describe. I was hoping for a joint DXpedition with you guys this summer, where we could have tested this (and many other variations) out thoroughly-- but you know how we accidentally ended up 98 miles apart :-) There is already an extra 12" tunable FSL here for running an A/B test like this, and as soon as I can track down a volunteer to join me on an ocean cliff DXpedition, I would be eager to run it (and post relative strength MP3's).

Re: [IRCA] Oregon Cliff (Cape Perpetua) Ultralight TP's and DU's for 8-19
Hi Neil, Last year in September at Yachats I tried recording on a Perseus with a 7-inch FSL antenna on the roof, starting out at sea level and driving up to the cliff side pullout near Cape Perpetua (same spot I was at one night in July, and where Gary just finished DXing). The drive (and recording) was approximately two and a half or three minutes from sea level to the cliff. Despite noise issues from power lines part of the distance and noises from the vehicle's engine, I could tell that signal strengths kept increasing as I was going up in altitude. If I remember right, the average boost was around 8 or 9 dB. I'm not sure if I still have that short Perseus recording, but I'll have to snoop around in my computer files. It would be interesting to repeat this experiment next time I'm in Yachats. 73, Guy Atkins Puyallup, WA -- Forwarded message -- From: neilkaz To: Mailing list for the International Radio Club of America < irca@hard-core-dx.com> Cc: Date: Wed, 21 Aug 2013 10:28:37 -0500 (GMT-05:00) Subject: Re: [IRCA] Oregon Cliff (Cape Perpetua) Ultralight TP's and DU's for 8-19 Have any of you compared ocean cliff reception to adjacent beach reception when using the EXACT same setup? ie...ULR and 12" FSL on the cliff vs same make ULR and a 12" FSL on a nearby beach? 73 KAZ ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com

Hi Nick, <<< When is your next expedition Gary? Can't make plans without knowing the dates (hi). >>> I would be honored to have a joint DXpedition with you, Nick, but I'm afraid that after two Oregon cliff trips within the past month, we need to save up a little more vacation time before we can make any more plans :-) My wife likes Cannon Beach, so we'll probably be booking a trip there again next summer. If you or Walt could join me then for a Rockwork 4 effort, I'm sure that we could have a real blast. There should be some new mega-FSL's to play with by then! 73, Gary -Original Message- From: Nick Hall-Patch To: Mailing list for the International Radio Club of America Sent: Wed, Aug 21, 2013 9:47 pm Subject: Re: [IRCA] Oregon Cliff (Cape Perpetua) Ultralight TP's and DU's for 8-19 When is your next expedition Gary?
