Recent FSL Antenna Experimentation

Gary DeBock
 

Noted MW-DXing antenna expert Dave Eichelman recently asked me about the latest FSL designs, which have emphasized compact DXing gain. The recent FSL experimentation is based on the premise that even a small FSL can run wild when it is in the right place at the right time. As such, its portability and quick setup nature become its primary advantages over other types of antennas. Paul Walker has run wild in Alaska over the winter with a modest-sized 5" FSL primarily because he tapped into Trans-Arctic propagation that has rarely been exploited. In the same way, another modest-sized 6" FSL was tested out at the Asia-facing Rockwork 2 cliff last October during exceptional propagation, and came away with apparent west-coast-first loggings of 594-Myanmar and 675-AIR (although the former was received frequently in Masset shortly thereafter, and later in the season).

The early experimentation to build monster FSL antennas was probably a little misguided, since even modest sized FSL's (from 4 to 6 inches) can be extremely effective if they have the advantage of great propagation. On the other hand, if you are chasing breakthrough transoceanic DX, when propagation is average or mediocre even the largest of antennas will put you to sleep. The FSL antenna's portability, quick setup and rugged survival give it a critical edge in harsh or wild environments like Alaskan snowfields or ocean side cliffs-- and since even modest-sized FSL's can run wild when conditions are great, the current mindset is to enhance portability by making the antennas lean, mean and capable of surviving any kind of nasty weather. Paul's FSL-DXing experience in the harsh Alaskan environment has been a bonanza for these efforts, as well as transoceanic DXing in gale-force winds and rain last March at Rockwork 2.

As such, during the Pandemic, the focus has been on producing compact new FSL designs like the 5 inch (13cm) FSL ("the Paul Walker variant"), a new 6 inch (15cm) FSL (the "Six Appeal" model) which tracked down the Asian DX last October at Rockwork 2, and a new 8 inch (20cm) FSL model tested out last summer for DU-DXing at Rockwork 4. These antennas are relatively cheap to construct, lightweight to carry, and provide a stunning gain boost whatever the conditions. But when the conditions are great, they can be the ultimate DXing thrillers for their tiny size. Since their mission includes survival in wicked ocean cliff storms, though, the current challenge is to make them "bulletproof" to survive even the nastiest rain, wind and cold. Sooner or later, a DXer needs to "pay the price" for enhanced ocean cliff propagation, and prove that he and his gear are up to the challenge.

Re: Headphones?

My personal preference for everyday listening is lightweight over the ear type. It is difficult to find good sounding headphones in this category. So far I like Koss Titanium. I had the old ones branded for Radio Shack, Realistic Pro 35, and they were great. In fact, I took out the old elements from the falling apart set and put them in the newer Koss KTXPRO1. These are good, too, but the old elements are a bit better.
I hate the earbuds.
I have Bose QC35 for music, but $270 is an overkill for radio.

Sorry, the formatting is off, that is 1404kHz - 2PK

Sennheiser has an "equivalent"  to the Sony mentioned above. It is the  HD280  PRO. It is considered a studio monitor sort of headphone like the MDR7506. The sound profile is quite similar so it is a good communications type headphone as well.  It is about  $20 cheaper than the Sony, if that matters. I have had a set for over 10 years using them fairly regularly, and they have held up fine. Like the Sony, they are closed, so when ambient temperatures are high, your ears can get uncomfortably warm over time (an hour or two depending...).
I have lots of headphones   (18 sets, a couple over the $2K mark) and IEMs (In ear Monitors, maybe 30 sets). The best sounding headphones or IEMs for music listening are not the ones I like best for DX or comms listening. I find that headphones with a "forward" midrange and lower treble are the best for speech intelligibility. The over the ear closed types (like the Sony and Senn) are best for digging out those hard to hear station IDs.
This is followed by the in ear type with good fitting tips. In last place are the ear buds. They (as someone mentioned) seem to not want to stay in my ears. Even when they are inserted properly, they do not couple well so you lose that intelligibility that the other two types do well. For portability it is hard to beat a set of IEMs. You don't need or want anything high end with multiple drivers or microphones with buttons to switch calls. Just make sure you get a selection of tips so you can get a comfortable fit that doesn't aggravate your ears over time.
Actually these are pretty darn good and relatively cheap:

I have a couple of sets that I use for DXing while travelling. I like them!

Hi Johnny, 

1404 kHz is the frequency, 2PK is the station callsign, they use combinations of numbers and letters in Australia :-)

WTMP 1150 STERO TEST TONIGHT--- STARTING IN ONE HALF HOUR (MIDNIGHT EASTERN)

Les Rayburn
 

WTMP (AM) - Wikipedia


WTMP 1150 kHz in Tampa, FL will be conducting a test in AM Stereo tonight per a post from owner Neil Ardman in the Facebook Group "I Love AM Radio."
Details are minimal but we assume that the test will commence at the start of experimental hours, beginning at Midnight Eastern Time (0400 UTC)
We can also assume that the test may be at their daytime power of 10,000 watts but this is NOT CONFIRMED.
No information on duration or programming. Some sweep tones, Morse Code IDs, etc. have been e-mailed to Neil but no word on if he received them in time to incorporate them into the test. Fingers crossed.

Best bet is to tune in and record the session, perhaps find an online remote SDR or live stream to verify your reception.

Re: Your current "personal" radio DX challenge?

Paul Blundell
 

I would love to see how it works for you, I have done another chunk last night and will be posting those results soon.

They are the main "variety" store here, sort of like Walmart for those in the USA.

Those are some interesting results, what was wrong with the 310ET?

To me it sounds like it could be used instead of "sweet" or "awesome"?


Also, I have performed some VERY informal tests pitting my DT-800 against my CCrane Skywave, Sihuadon R-108 and Tecsun PL-310ET, and found the DT-800 to be able to really "hold it's own" against these other radios and the DT-800 was able to "hear" most of the same things (95%?) on AM that these other radios could, surprisingly.  FM was almost as good, but the R-108 is pretty hard to beat on FM.

PL-310ET had to go back to the shop and will be replaced by a PL-330 (in transit).


Thanks all!

Re: Sangean DT-800

Phil Pasteur
 

I have been known to use the term, but combined with high, as in "High Zoot". I used it to mean advanced/good. or the like.
from word reference forums
high-zoot = approximately "really cool" From "zooty" - sharp, fashionable, showy

Hi Patrice, 
1125 RNE-R5 Todonoticias Álava from Vitoria. RN is one of the Spanish Public National Radio channels (RN de Radio Nacional de España RNE). The second one, mainly focused on news and cultural short programs, is Radio 5 (R5 de Radio Nacional de España RNE) . 
From Vitoria, RNE-RN ID will be 'Radio Nacional de España Euskadi' with regional news, and RNE-R5 ID 'Radio 5 Todonoticias Álava' with local news. 
¡Buen DX!
