Congratulations Gary………If it was pouring Rain and Windy, you should be allowed to add another 100 Miles on that for a Bonus!!!

Amazing Stuff…..who would have ever imagined where this ULR phenomenom was going to end up way back in 2008!!

558-Radio Fiji One English ID

Gary DeBock
 

I'm still going through the file review for the August Rockwork 4 DXpedition, and still coming up with a few surprises. Most TP-DXers know that 558-Radio Fiji One is the native language program in Fiji, while 900-Radio Fiji Gold is the English program (which Theo recently assured me is being heard very well in NZ, despite the fact that it apparently never showed up for us on the Oregon cliff).

With the rejuvenated 558-Radio Fiji One pounding in on most days with potent-level island music it was already a great improvement over past DXpeditions, but while reviewing the August 8th recording I was able to come up with a Radio Fiji One English ID for the first time in 9 years of TP-DXing (at a near S9 level to boot) at 1315 UTC on that exceptional morning, at the 27 second point
https://dreamcrafts.box.com/s/2m8y5m0aixae080rj3uvfqivecbz7gni
This was the first English that I have ever heard on RF1 (after about 18 receptions), so it was quite a surprise. This was received on a 7.5 inch loopstick Tecsun PL-380 Ultralight boosted by a 15 inch "Airport Unfriendly" FSL antenna on the ocean cliff near Manzanita, Oregon.

Rockwork 4 DXpedition-- Last Day Video (Murphy's Law)

Gary DeBock
 

Everything seemed to go perfectly in last August's Rockwork 4 DXpedition, with multiple South Pacific loggings, great weather, exotic DX and breathtaking ocean scenery. Murphy's Law seemed a distant memory until the last day-- when I attempted to shoot a DXpedition video at the awesome Highway 101 ocean cliff site.

My wife had somehow changed the camcorder video setting to a lower resolution, and although a 7 minute DXpedition video was carefully shot at the site, the video ended up being somewhat less than HD before I could check it. Because of this the video was never uploaded to YouTube until today, when I finally decided that its good points possibly outweighed the oversight. For those interested, the "less than HD" August 2017 Rockwork 4 DXpedition video is posted at https://youtu.be/45OmZ0sWoQU

Rockwork File Review-- 531-6DL // 594 During Sports

Gary DeBock
 

I'm still going through a huge amount of Rockwork 4 recordings from the exceptional August DXpedition, mostly 531 kHz recordings made unattended on a backup 15 inch FSL (about 15 hours worth). There have already been multiple ID's of 4KZ, hours and hours of Samoan music from PI, about 5 solid receptions of More FM, long call-in phone sessions on the Australian SRN station 2PM-- and a single morning's appearance of 6DL from Western Australia.

My DXpedition partner Tom R. was kind enough to pull up some LR network parallels to confirm my 6DL reception at 1253 on 8-4, but further file review of that morning's 531 kHz recording revealed a sporting event on the Australian LR network early on (around 1222), which matched the same program on 594-3WV (there is no programming time delay between Western Australia and Eastern Australia during sporting events). Since 6DL is the only ABC station on 531, that was enough to make sure of another reception of the 10 kW station at 9,050 miles (14,564 km) at 1222 that morning (8-4)
https://dreamcrafts.box.com/s/2ms23dtebe7zvl6v0mynhxhjmcqinbs8
594-3WV reception at 1225 on 8-4, with the same announcer and sporting event
https://dreamcrafts.box.com/s/bl3iiisd3buj2ns22zb9i8mjdh7wqow7

Hopefully the DXpedition file review will be completed before our planned return trip to Kona, Hawaii in December :-)

For Sale is a One Of a Kind, One Meter, Hex Air loop Antenna fo the MW Band

Everett N4CY
 

For Sale is a one of a kind, One Meter, Hex Air loop Antenna, designed of the MW band, covering 1745 to 470 KHz. The antenna is wound with 330/46 Litz wire and stands 64" high and 36" wide and is mounted on a Lazy Susan. The antenna frame is build out of Quarter Sawn Red Oak from a 200 year Old Tree. The antenna has a 50 ohm output, which is connected to a one turn loop and is connected to a matching transformer network.
 
I am asking $150 for the loop, however, it is too large to ship so the buyer must pick it up in Tuscaloosa, AL if interested. I can be contacted at everettsharp@....

Tecsun S-8800 AM/LW/FM/SW/SSB Radio With Remote

by radiojayallen

The long wait is over – the new Tecsun has hit the streets and will no doubt garner lots of attention among radio listeners everywhere. In an age where manufacturers seem to be producing increasing numbers of inexpensive radios of every conceivable description this new Tecsun clearly takes aim at what has become the high end of the portable radio segment. The inclusion of a remote control sets makes it unique but at prices near $300 delivered purchasers will be expecting top performance. This report will describe exactly how well Tecsun did!

For Sale 7.5" X 7.5" FSL

Everett N4CY
 

I have for sale a 7.5" X 7.5" FSL. The FSL is wound as a 2 coil Polydorff configuration. The 2 windings were wound with 660/46 Litz wire. The variable capacitor is one of the high Q, 2 gang, Russian units with a 3:1  ratio. I added a band switch so the second gang can be switched in for extended band coverage. The FSL is mounted on a Lazy Susan base.
 
Band (1) tunes from 2,000 to 420 KHz and Band (2) tunes from 575 to 275 KHz. The tuning is sharp and the rotational nulls are quite sharp. The FSL is setup for induction coupling only. This will, by far, outperform my One Meter Loop.
 
I am asking $330, which includes the shipping to the lower 48. Below are pictures of the FSL. If interested please contact me off list everettsharp@.... This is the last one I will build, as I have sold all of the ferrite bars that had on hand.

Re: Question: Which Analog Sony SRF Walkman Would You Rate the Best ULR?

davidgeorgerichards
 

Thank you for the swift reply Gary!

<<<  If you have performed the recommended loopstick and variable cap trimmer alignment on the black SRF-39 and find that it is still inferior to the SRF-59 in AM sensitivity, then you most likely have a "dud" model with some type of inferior component(s), possible related to age deterioration. My own experience with the straight SRF-39 is very limited-- I purchased and aligned a single model, which ended up working as well as the SRF-39FP's. Most likely if you purchase and align a different one, your experience will be the same, Dave. Good luck!  >>>

The difference in sensitivity is very minor, but you know how it is with very weak signals - even a very small difference can have a big effect on intelligibility. I may well try another one. Besides - it doesn't hurt to have an extra one or two lying around for parts :-)

Thanks once again!

Dave


Re: Question: Which Analog Sony SRF Walkman Would You Rate the Best ULR?

Hi Dave,

<<<   Apologies for reviving a rather old thread.   >>>  

Not at all-- a lot of us enjoy tinkering with the high-performing Sony analog receivers (which actually got our Ultralight radio group started, about 10 years ago).

<<<   Recently, I purchased another SRF-59, aligned it, and mailed it to a friend to show him how good the performance of such a small AM radio can be, Then last week, on a whim, I purchased a NIB SRF-39 - the regular black model. After alignment, it performs well, but is not quite as hot as my SRF-59. No amount of re-tweaking can change that.    >>>

The regular black SRF-39 model is somewhat of a rare item in comparison to the SRF-39FP "Prison Radio," which was widely purchased and used by our Ultralight radio group from 2008-2010. I personally aligned about 15 of those models, and sent them to DXers in Canada (who were unable to purchase them off of eBay, due to shipping restrictions imposed by the seller). As far as I know the circuitry of the SRF-59 and SRF-39 models is identical, although the SRF-39 (and the SRF-39FP) use somewhat higher quality components which are designed to provide increased longevity (especially the variable cap, which typically develops the "scratchy tuner" issue in the SRF-59 after about two years of heavy usage).

<<<   No amount of re-tweaking can change that. The audio on the SRF-59 seems just a bit less bassy and a bit more pronounced at the high end, and more suited to copying weak stations. RF-wise, it's a tiny bit more sensitive too. I listen to local low power TIS stations at the top and bottom of the band to verify this. I'm wondering whether this is simply a case of unit to unit variation, or if there were any circuit differences between the SRF-39 and later SRF-49 and SRF-59 models. I'm tempted to purchase a number of them in order to find out, but am uncertain whether I'm really that committed!   >>>
