Many thanks to SWLing Post contributor, Gary DeBock, who shares the following notes and recordings from an Ultralight DXpedition in Kona, Hawaii:

The Kona, Hawaii Ultralight Radio DXpedition was conducted from a sixth floor oceanfront motel room in the Royal Kona Resort Motel from April 9-12 (during an anniversary trip with my wife). A newly designed “airport friendly” 5 inch FSL antenna (designed to fit within hand-carry luggage, inside a plastic tote) and a 7.5 inch loopstick C.Crane Skywave Ultralight were used to track down and record Asian and South Pacific Medium Wave DX from such rare stations as 540-2AP (Apia, Samoa), 621-Tuvalu (Funafuti, Tuvalu) and 1440-Kiribati (Bairiki, Kiribati). Here are three extremely strong recording links for these exotic stations, including the daily sign off routines for 621-Tuvalu and 1440-Kiribati:

540 2AP Apia, Samoa Extremely strong Christian worship music (Samoan style) at 0931 UTC on April 9 (S9+ level)

621 Tuvalu Funafuti, Tuvalu Over 8 minutes of traditional island music at an S9 level, including the sign off routine (with national anthem) at 1000 UTC

1440 Kiribati Bairiki, Kiribati Over 7 minutes of traditional island music, station ID’s in English and the native language, and the national anthem (followed by a blistering 1000 Hz tone) at the 0936 UTC sign off– all at a strong level

Video: Gary DeBock’s “Baby FSL” antenna

Many thanks to SWLing Post contributor, Gary DeBock (N7EKX), who shares this video and notes the following on YouTube:

This is the new 3.5 inch (89mm) “Baby FSL” antenna, designed to provide a powerful DXing gain boost for Ultralight radios (or any other portables) despite its very small size. It has 32 Russian surplus 140mm x 8mm ferrite rods and 31 turns of 1162/46 Litz wire. In the demonstration video it provides a daytime DX gain boost for 750-KXTG (Tigard, Oregon, 50 kW at 160 miles) from inaudible up to about S7 on the Eton Traveler III Ultralight radio.

Gary is certainly a first-rate DXer and an ambassador of our radio hobby. Gary shows us here that, with a little ingenuity, we can take a $50 radio and turn it into something exceptional! Homebrewing at its best.  Thank you, Gary!

Also, I had never considered that a high-gain FSL antenna would require very precise placement of the receiver for proper inductive coupling. It makes sense, though. This loop is tuned for razor-sharp precision!

Some day, when I have a little free time, I’m going to build one of Gary’s FSL designs.
