October 2020 Rockwork 2 TP-DXpedition Video

Gary DeBock
 

About 85 years ago the decision was made to blast an ocean coast route on the side of a towering mountain right on the Oregon coast, in order to allow Highway 101 motorists to stay close to the ocean during their travels. Serious dynamite was used to blast through solid rock 500 feet (150m) above the salt water, with an additional group of turnoffs engineered so that motorists could stop and enjoy the awesome ocean scenery during their travels.     

For the past 9 years Mount Neahkahnie on the Oregon coast has offered west coast DXers the chance to chase superb DU-DX in the summer from these turnoffs, breaking New Zealand and South Pacific NDB DXpedition records, as well as becoming an ideal testing ground for compact broadband and FSL antennas. The Rockwork turnoffs have always been identified with DU-DXing in summer weather, since the ocean cliff environment was thought to be too risky for DXing in other seasons, and since all the cliffs seemed to be facing toward the South Pacific. Or are they?
 
As it turns out Mount Neahkahnie does have a western face, and one of the largest Rockwork turnoffs is located right at the point where the cliff's southwestern face becomes a western face (see photo). When you view the salt water beach below this turnoff, however, you will see that it has an ideally shaped cove facing due west toward the Asian direction-- exactly how how the most popular DU-DXing turnoff (Rockwork 4) has an ideally shaped cove facing in the South Pacific direction. But serious Asian DXing had never been attempted at the Asia-oriented Rockwork 2 turnoff. Was this another transoceanic signal-boosting venue waiting to be discovered, offering TP-DXers the chance to enjoy cliff-boosted Asian signals far stronger than what would seem likely with their small antennas?
 
To answer this question I decided to visit this Asia-oriented Rockwork 2 turnoff with a tiny antenna indeed-- a 6 inch (15cm) diameter FSL that can be held in one hand. As for the receiver, a modified pocket radio (7.5 inch loopstick C.Crane Skywave) would be used in a live DXing format, and a Sony ICD-SX57 digital recorder would keep a record of any interesting catches. As for the "Asia Cliff" investigative mission, I knew that simple reception of only Japanese, Korean and Chinese signals wouldn't impress anybody, since all these can easily be received at most TP-DXers' home locations. "Big gun" reception of stations like 738-Taiwan and 1575-Thailand also wouldn't convince anyone that the cliff was boosting Asian signals, even with a 6 inch antenna. In my opinion, what would be some pretty convincing evidence would be the reception of any MW station from Bangladesh, Cambodia, Myanmar or India. The concept of a 6 inch antenna tracking any of these down would seem to border on science fiction, and had never been seriously attempted or completed on the west coast of the continental U.S. So why not give the Asia-oriented Rockwork 2 cliff this "acid test," and see if it could pull off such a shocker?

Well, the Rockwork 2 cliff did indeed pull off such a shocker last week, tracking down not only a couple of stations from the "exotic" category, but many other astonishing Asian receptions as well. A DXpedition video showing the ridiculously small gear is posted at the following link, offering convincing evidence that such humble equipment had no hope of tracking down such exotic DX without a freakish cliff boost . The "Asian Cliff" has been discovered-- and offers some serious excitement in the future!  https://www.youtube.com/watch?v=-tlrX_52shc&feature=youtu.be

I did something like that but with the "clear channel" stations
listed. And the classes.

Thanks Paul.

I just had a look at that, it only has a 1KG weight limit, between my 3" FSL, radio and the weight of the MDF on to the top to hold it all, I am going to be well over that.

Thanks Paul! This is really interesting, and I may try the idea with the LoG connected to the ground terminal of a Bonito MegaDipol MD300DX. I don't think it will hurt reception and might actually be a boost, if the article author's experience holds true.

Oklahoma TP DX 10-11-20

Richard Allen
 

TP DX this morning was the best here in quite some time (LSR at 1233 GMT).

567 JOIK fair at 1226, audible to 1235.

594 JOAK good at 1219.

693 JOAB fair at 1222 until 1237.

747 JOIB fair at 1201 until 1241; overall the best signal of the session.

774 JOUB poor 1159, signal ploughed under by semi-local KSPI on 780.

828 JOBB fair at 1208; poor at 1239.

972 HLCA audible from 1155 until 1238 often peaking at a good level.

1287 JOHR poor (fully readable) at 1230.

1566 HLAZ poor at 1241; barely audible at 1245.

Skywave SSB with 8-inch FSL.

FSL and Radio Stand

Paul Blundell
 

I am looking for a portable method for using my 3" FSL and radios while out and about.

I have seen the stands that Gary uses, I was think something like a camera tripod, would this be too heavy for that?

Ideally a portable table / stand would be great, does anybody have any ideas?

It sets up as my older Tecsun DSP's as far as time, and the English buttons are concerned. Placement of the buttons are a bit odd, and these function buttons are a bit small. Nonetheless things went smoothly. The "dial light" is a pleasant yellow, not too bright. The included battery is at least partially charged, and shows 2 of 3 bars right now. The case itself is good looking and of a solid build. For as light-weight as it is, it does not feel cheap. The buttons have a nice tactile feel to them, as opposed to a squishy feel. The rotary encoders for frequency and volume are a bit slow without a lot of indent.

The reception of AM-BCB is as good as the original PL-310, and better than the PL-310et I borrowed. I will say that the 330 is NOT a daytime DXer, and the 310 was also weak in this respect. This in regards to a habitually noisy suburban environment in Cent. CT USA. 1030 WBZ Boston (150mi) weak with hash, and WGY 810 in Schenectady, NY (140mi) non existant. WWKB Buffalo 1520 (225mi) illegible in the hash... 550 WGR Buffalo did better but still poor. Pointing the radio towards New York City (80-100mi) garnered good reception of 540 WLIE, 660 WFAN, 880 WCBS, 740 WNYH, 1010 WINS, and 1130 WBBR. Fair to poor on 820 WNYC. WWRL on 1600 didn't get here midday, but WWRU 1660 did, though fair. All these receptions were made offsetting the intended channel by 1kHz to avoid Soft-Mute.

Skywave RX at night brings out the Eastern USA with exeptions due to co-channel. All Chicago-5 heard well here 670, 720, 780, 890, and 1000. 650 WSM, and 750 WSB after 9PM, and KWKH and WDFN on 1130 duke it out behind big-sig WBBR on 1130. 1120 KMOX St Louis, KDKA Pittsburgh, KYW Philadelphia, CJMS 1040 Montreal when nulling WHO Des Moines and WVON Avon, NY. CHLO (ex-CIAO) Brampton, ON and R. enciclopedia Cuba on 530. Nighttime is the right-time for DX. No KOA or KPNW, or WWL just yet... its early in the season.

FM is just as good as it gets with DSP, picks up clean signals with meter readings like 03:01,02:00. If its there the PL-330 and PL-310 will get'em.

SW gets here too. I don't find too much different than an originaal PL-310,and a bit better than the "et" model. Being high-powered, all thats needed is that the transmitter is pointing in your direction. From here in the N. E. USA RRI, REE, CRI, and Greece all get here. Time signals on 3330, 5000, and 10000 all have their better reception periods, 3330 CHU is best almost all night here.

USB/LSB both work very well with the 330, a feature not found on the PL-310/et/380. This is where the extra $$'s go. And IMHO its worth it. Having owned a Grundig G5 (Degen 1103-PLL clone), aviation weather could be heard from NY/Gander and Trenton (Canada) military routinely. But the 50Hz increments were a bit coarse for "dialing it in". And Shannon (Ireland) Volmet was rather weak with volume bump needed. The PL-330 has a 10Hz tuning step, and does dial it in nicely. New York Aviation is off-air/silent, so only Gander gets here, and it does better than the G5. The mild surprise is Shannon Volmet gets here with improved legibility and signal. Trenton mil-Volmet has been dicey as reported in other "io" groups, and it did come in weakly once in several tries. It did have a weak meter reading with hash. Shannon had weak hash and Gander mild hash. If you want USB/LSB reports are the PL-365 and this PL-330 are both worth the extra US$30. For SYNC detection the PL-660 shines... the PL-330 DOES NOT. Much like Long Wave, its a selling point, nothing more. At least for US$70-80 I don't feel ripped-off. If I were buying a PL990(x) or H501, I'd be VERY dissatisfied to the point of returning it.

As for the Amateur bands, I'll leave that to the Amateurs that routinely receive such for their opiniion. As a civilian, I'll step aside. But I do think that the SSB on this model is worthy at least.

So there are my opinions as a newling to the PL-330. Its a good 4 of 5 with a little plus for the SSB, and a little minus for the SYNC and LW band.
