Hi Gregory, Your question is very similar to one by J.P. Tuttle on July 29th, concerning the currently approved Ultralight Radio models. Of course there have been many new pocket radios introduced sin

Hi Mike, <<< A couple more ideas for experiments. Maybe you or somebody else tried these already? 1. Place the rods "in series", creating an arbitrary long stick. Say, 4x140mm=560mm. 2. Leave spaces b

<<< I listened to that recording multiple times and the signal is to low down for my ears. I was able to pick out a couple of words but unfortunately no clue as to who it was or an id. I heard 4KZ in

Hi Chris, Thanks very much for listening to the two mystery recordings from the Rockwork DXpedition. Usually on the "Kiwi Cliff" we get a mix of 531-PI and 531-More FM, so the 531 Australian station f

These two 531 kHz recordings were made during the Rockwork ocean cliff DXpedition on the Oregon coast last month, and both feature an Australian call-in talk station alone on the frequency. I'm pretty

Hi Joe (and Steve), Thanks for posting the link about the 3.125" x .39" ferrite rods for sale from Electronic Goldmine. They sound interesting, but in comparison to the Russian surplus ferrite rods (s

Tom Rothlisberger and I had the thrill of conducting the tenth annual Rockwork Cliff DXpedition this month, and once again lucked out with some exceptional South Pacific signals, especially on Longwav

If anyone ever wondered why a DXer would want to set up on the side of a plunging ocean cliff at 0500 local time and go all-out to track down "impossible" transoceanic DX on "hopelessly" humble gear,

Take a break from the wacky Pandemic and escape with Tom Rothlisberger and me to a wild, plunging cliff on the Oregon coast-- 500 feet (150m) straight down to the Pacific. Shot right in the middle of

Australian stations kicked into high gear at the plunging Rockwork cliff this morning as 558-6WA in Wagin, Western Australia managed a pretty decent signal on a new-design 8 inch (20cm) FSL antennas (

Hi J.P. (and Max), During the worldwide Ultralight Radio Boom in early 2008 we had a very dedicated group of volunteers to handle administration, a classification and awards program, numerous Ultralig

Amen to that, home town brother! The reality is that when you spend some serious vacation $$ to show up at an ocean side cliff and/ or exotic overseas ocean beach with FSL antennas and completely depe

Thanks Steve (and Dave), The possibility that the "Q" of older variable caps degrades over time because of environmental factors is interesting, and I appreciate your experimentation regarding this. T

Hi Gord, The "N50 384P" variable cap from Mike's Electronic Parts (at the link you posted above) is exactly the same as the one from Oren Elliot Products, despite the much cheaper price. Oren Elliot i

Hi Steve, <<< Where are you obtaining the latest 0219 variable caps--from the manufacturer or from Mike's Electronics? This is certainly a very interesting finding. 73, Steve >>> During the Pandemic I

Hi Steve, Thanks for running these detailed "Q" tests between the 1162/46 and 660/46 Liz wire at various frequencies with the HP4342A Q meter. This kind of detailed test is something which would not b

<<< Hi Gary, Your new 6 inch FSL is a step towards higher gain in a relatively small package. I look forward to a YouTube review. >>> Thanks Todd, The master plan behind this new 6" FSL design was to

Hi Gord (and Todd), Todd, thanks for your interest and questions about the new 6" FSL design, which I plan to answer in detail within a day or so. Gord, 660/46 Litz wire was actually used in all of th

Paul, The solution is a "rubber locking tab," which is precut on one side to fit around the curved PVC fitting, and cut flat on the other side to fit up against the rubber plumbing coupler. The rubber
