I recently received an email from SWLing Post friend, contributor and Patron, Mark Fahey, who is currently enjoying a fascinating DXpedition.
Many thanks to Mark who has allowed me to share a few of his notes from the trip. Mark writes:
I am at Susut, in the Bangli Regency, on the Indonesian island of Bali.
This treehouse is at the base region of Mt Agung, an active volcano, so the earth rumbles a few time each day.
For the next week and a half, I am alone in the Indonesian jungle with my WinRadio Excalibur a collection of loops and wire antennas and lots of storage for spectrum recording. No QRM, I am running on DC, but charge my gear during the day from an AC mains supply.
DX is fantastic – best today being CNR in DRM locked solid!
But the big disappointment is just like Malaysia, MW in most of Indonesia is now just white noise, nothing at all – and hardly any RRI (Radio Republik Indonesia) on the tropical bands now.
But FM jam-packed, I expect many are community pirate stations as well. I came all setup for FM capture as well.
Wow! What a brilliant DXpedition location, Mark! It appears you’ve truly removed all other distractions being in such a remote area.
Sign me up! I’m ready for some Indonesian tree house DXing!
Thanks for sharing, Mark! [And by the way, I’m not at all envious. Okay, maybe just a little. Or a lot.]

Top Ten DU signals from the August 2018 Rockwork DXpedition
– Gary DeBock
Life is good– breathtaking ocean scenery, an innovative compact antenna, thunderous DU signals and even a partner (Craig Barnes) to share in the bounty. Who could ask for more?
Listed below are the Top Ten DU signals recorded during the recent Rockwork ocean cliff trip (near Manzanita, Oregon) from August 1-9, including several low-powered Kiwi stations which acted like “big guns” pretty much throughout the DXpedition. All of these were recorded with 7.5″ loopstick portables (CC Skywave SSB and XHDATA D-808) and “Airport Unfriendly” 15″ and 17″ FSL antennas (guaranteed to send TSA agents into a security alert).
531 More FM Alexandra, New Zealand, 2 kW The obscure modern rock station usually managed at least one S9 peak each morning, and was fully competitive with Kiwi co-channel PI for the first time. This TOH recording at 1300 on 8-8 demonstrates its potent capability at the cliff
531 PI Auckland, New Zealand, 5 kW Pacific island music at a huge level at 1248 on 8-7 was typical from this low band powerhouse, which was frequently in an all-Kiwi snarl with its overachieving co-channel More FM
558 Radio Fiji One Suva, Fiji, 10 kW The donated Japanese transmitter still puts out awesome signals for this native-language powerhouse, including this island music with a Song Medley ID (“Radio Fiji One, na domoiviti”) at 1:38 into this recording at 1252 on 8-1
567 RNZ National Wellington, New Zealand, 50 kW After demolition of its old tower the RNZ big gun has sometimes sounded anemic on the west coast, but certainly not at 1320 on 8-3 with Indian-accented English
594 Star Timaru/ Wanganui, New Zealand 5 kW/ 2 kW Another Kiwi overachiever, this low powered network was socking it to the Oz big gun 3WV all week, including with this powerful Christian music // 657 at 1326 on 8-3
657 Star Wellington, Tauranga, New Zealand 50 kW/ 10 kW The flagship Star station sure was playing the part with Christian music at an overwhelming level at 1238 on 8-6, including an ID at the end of the recording
765 Radio Kahungunu Napier-Hastings, New Zealand 2.5 kW The overachieving Maori station was its usual potent self with island music and Maori chants at 1218 on 8-1; it was usually slightly stronger than its 603 parallel (Waatea)
936 Chinese Voice Auckland, New Zealand 1 kW One of the most incredible signals of the entire DXpedition– the 1 kW ethnic station pounds into the cliff at an S9 level at 1309 on 8-2– ocean cliff propagation at its finest!
1017 A3Z Nuku’alofa, Tonga 10 kW Yikes! The rejuvenated Pacific island big gun thunders into the cliff with the strongest signal I’ve ever heard recorded in North America, featuring island music at 1314 on 8-1… almost loud enough to wake up the sleeping squatters
Many thanks to SWLing Post contributor, Gary DeBock, who shares the following notes from his Cook Islands Ultralight DXpedition:
Sunset on the Cook Islands
Aitutaki Sunset DX
Aitutaki in the Cook Islands had some dazzling sunsets, and [my wife] loved to take sunset pictures with her new phone. Of course, I participated as well. As a result, sunset DXing was pretty rare while on the trip, although 7 USA mainland stations crashed the Kiwi sunset skip DXing sessions later in the evening around 0700 UTC. None of the usual Vancouver-Seattle-Portland-San Francisco TP-DXing pest stations made it to the South Pacific, though– and I didn’t miss them a bit! 🙂
610 KEAR San Francisco, California (5 kW at 4,610 miles/ 7,419 km) “Family Radio for the West Coast,” Christian religious format received at fair level at 0835 UTC on 4-12:
1170 KFAQ Tulsa, Oklahoma (50 kW at 5,642 miles/ 9,080 km) Strong signal over apparent DU English co-channel with “Coast-to-Coast” ID at 44 seconds; thanks to Richard Allen for confirming the broadcast of the program on the station at 0845 UTC on 4-12:
Checking out transoceanic DX propagation at an exotic ocean beach site can provide the hobby thrill of a lifetime– if a DXer is lucky enough to choose the ideal time, place and gear to make the chase. All of these fell into place in an amazing way during a 5-day trip to Aitutaki Island (2600 miles due south of Hawaii) with Ultralight radio gear, resulting in the reception of MW stations in India, Bangladesh, Mongolia and Cambodia– all at over 6,800 miles.
Because of extensive QRM from Australia and New Zealand the total number of Asian stations received was limited, but it was definitely a case of quality over quantity. Phenomenal gray line propagation around sunrise shut down Japanese signals almost completely, but boosted up those from the exotic countries in east and south Asia. Korean station reception was limited to the big guns, which was also primarily true for Chinese signals. Except for the ANZ pest QRM, the conditions seemed custom-designed for a west coast DXer to go after the exotic stations which rarely– if ever– show up in BC, Washington or Oregon (even though the Cook Islands’ distance to them is greater).
7.5 inch loopstick C.Crane Skywave SSB Ultralight
Ocean beach propagation at sunrise was strong enough to bring in both 693-Bangladesh and 1431-Mongolia at S9 levels almost every morning on my Ultralight gear, and allow both 657-AIR and 918-Cambodia to break through ANZ QRM on April 12th. No doubt many more of these exotic stations could have been logged except for Australian QRM on 576, 594, 872, 883 and 1566, but this only added to the thrill of the chase. The overall results were exceptional for a DXer using only a 7.5 inch loopstick Ultralight radio and 5 inch “Frequent Flyer” FSL– all designed to fit within hand-carry luggage, and easily pass through airport security inspections. Thanks very much to Alokesh Gupta, Hiroyuki Okamura, Jari Lehtinen, Chuck Hutton and Bruce Portzer, who all assisted in the identification of these stations!
657 All India Radio Kolkata, India, 200 kW (8,075 miles/ 12,995 km) Recorded by accident during a sunrise check of the Korean big guns at 1641 on April 12, reception of this longest-distance station went unnoticed until file review after return to the States. The female speaker (in the Bengali language) is the third station in the recording, after the female vocal music from Pyongyang BS and the Irish-accented male preacher from NZ’s Star network. Her speech peaks around 40 to 50 seconds into the recording. The isolation of the Star network at the 55 second point was done by the Ultralight’s loopstick, not by the propagation. Thanks to Alokesh Gupta for the language and station identification:
657 Pyongyang BS Pyongyang, N. Korea, 1500 kW Like most east Asian signals the N.K. big gun sounded pretty anemic in the Cook Islands. Its female vocal music at 1641 on April 12th shared the frequency with NZ’s Star network (Irish-accented preacher) and AIR’s female Bengali speaker:
693 Bangladesh Betar Dhaka, Bangladesh, 1000 kW (7,960 miles/ 12,810 km) Probably the biggest surprise of the DXpedition, with S9 signal peaks on 4 out of 5 sunrise sessions. Frequently snarling with the Oz pest 3AW, it usually managed a few minutes on top of the frequency each morning from 1630-1700 UTC. Exotic South Asian music was the usual format, and was very easy to distinguish from the talk-oriented format of 3AW (and other Oz co-channels). This first appearance at 1652 on 4-10 featured a “Bangladesh Betar” ID by a male speaker at 8 seconds into the recording (thanks to Chuck Hutton for listening):
774 JOUB Akita, Japan, 500 kW Oddly enough, this was the only Japanese signal making it to the island during the entire trip. Mixing with a goofy-sounding 3LO announcer at 1613 on 4-11, the Japanese female speech concerns a “doobutsuen” (a “zoo” in Japanese, similar to what the frequency sounded like with the 3LO announcer):
909 CNR6 Quanzhou, China, 300 kW Strong signal with CNR ID (1:08) and Mandarin speech by male and female announcers. NZ’s Star network was apparently off the air at the time, since it was a real blaster when transmitting:
918 RNK Phnom Penh, Cambodia, 600 kW (6823 miles/ 10,981 km) Breaking through the Shandong and Oz QRM at an ideal time to dominate the frequency, its sign off transmission with the National Anthem peaked just before the 1700 TOH on April 12. Female speech in the Khmer language and exotic music are featured just before the anthem (thanks to Hiroyuki Okamura and Jari Lehtinen for listening, and identifying the National Anthem):
Shandong RGD’s transmitters were poorly synchronized, resulting in the two-tone time pips at the 1700 TOH on 4-12 (during Cambodia’s National Anthem at 1:40, in the MP3 linked below). Although actually from two different transmitters, the sound effect sounds similar to that of a “cuckoo clock,” resulting in some initial confusion about their source:
1377 CNR1 Synchros (Various) Overall this was not only the strongest Chinese frequency on the band, but was the strongest Asian station on the band as well. Awesome S9+ signals were typical each morning, as with this male speech and music at 1622 on 4-12:
1431 Mongolia (Relay Station) Choibalsan, Mongolia, 500 kW This station was easy to receive on the first attempt, with very little competition on the frequency. It typically managed an S9 signal after 1630 daily with the BBC’s Korean service, which seemed to be broadcast during the peak sunrise enhancement time in Aitutaki’s ocean-boosted propagation. Here is BBC’s Korean male announcer at an S9 level at 1632 on 4-11, with the BBC interval signal at 47 seconds into the recording:
1566 HLAZ Jeju, S. Korea, 250 kW A very poor signal was typical during this trip, with the Chinese service barely showing up under 3NE and two other DU English stations (probably 4GM and Norfolk Island). Whenever 3NE was in a fade it had a chance, since other two co-channels were running very low power. Here is the latter situation, with the weak Chinese barely audible under the DU English snarl at 1641 on 4-12:
Amazing, Gary! Thank you for taking us along on your excellent Ultralight DXpedition. With a modest portable radio and a little antenna ingenuity, you’re enjoying some outstanding DX! You’re living proof of the point I was trying to make in a post yesterday!
Thanks again, Gary, and good DX!
