I have a question. I know some Yacht Boy model numbers from the 1960's or so where later reused. Are you talking about the modern vertical format radio made in Asia [I believe] or a much older European Grundig model? - FARMERIK

In the near past, especially when I was researching "do I really want a YB-500 for the collection AND to actively use ?"...every time I located material online, it most often said or mentioned "single conversion", hence I presumed it, and stayed determined to find out for myself later. Grin, well, I found out. I believe that in many older reports, reviewers appear to have left out a line from the YB-500 Service Manual -- perhaps Owners manual -- on paper or PDF...as the first line states single conversion, meaning for the FM band -- the typical 10.7MHz IF. The SECOND line down was seemingly omitted, that of course stating that the LW / AM / SW is indeed dual-conversion -- again, the typical back then 455KHz + 45MHz dual-conversions. So, sorry if I was confusciobsuraced, but I am cured....:)... RE: << If you have other info I'd really like a copy for my files.

Grundig Yacht Boy 500 / YB-500 Notes
josephrot
14 August 2015...
UPDATED: After two weeks spent with a well-maintained previously owned Grundig YB-500... Was and am surprised that even though the YB-500 seems to be known as a single-conversion receiver, it's actually dual conversion on LW / AM / SW bands -- 455KHz / 45MHz -- and single conversion on FM. Explains its remaining acceptably sensitive, good selectivity, and spurious images do not seem to present particularly nasty problems. Audio quality is a pleasant positive surprise, though not stunning, as the speak is small but with a heavy magnet and rubberized cone edge. Sometimes wish that it had an external antenna connector, but you can clip connect external SW antenna to a collapsed whip antenna, or use a tuned loop on AM broadcast band. The Tune Up / Down press-button method sometimes "feels" strange, but it too works overall OK, and direct key entry is easy and straightforward.. SSB reception is clear, easy to tune, as are the other FM, LW, AM and SW bands. Being a little "top heavy", I find using the YB-500 in a plastic stand is a positive. The unit is a good "traveler" as well, and quite suitable for vacation, "field DX" use and camping trips. Battery "thirst" is moderate, and definitely do NOT use a switching AC adapter. It's size and "heft" likely places it near or outside of the Ultralight category, yet the overall performance and functionality appears to make it a good "hefty Ultralight" choice. Sometime will compare to the Tecsun PL-660 as a "modern" receiver, yet the humble opinion here is that the YB-500 was and remains a capable all around receiver even today. Comments and other users findings most welcome and appreciated. Joe Rotello / Knoxville, TN / USA |

That's part of building what I think, is contacting others for feed back, opinion...and that such feedback and user opinion, like /dislike, etc. is VERY much needed and welcomed...
It appears we will be adding a "Better Benefits from the Grundig YB-500" sort of a white-paper / report being compiled, but more importantly is gathering ideas, comments from others, especially those that have had longer-term association with the likes of the YB-500 than I have, mine going on a second week now..
...some impressive ideas seen in my YB-500, regardless that it was a product I believe of the late 1990's / early 2000's.
Again, opinion, ideas, comments welcome, but knowing we are all busy, not needing to "write a book" about it. And yes, I will leave a few of my findings, opinion and comments as well.

August Rockwork 4 DXpedition-- Top 7 Exotic DU Loggings
Hello All,
From August 6-10th another wild "Cliffhanger DXpedition" was
conducted on side of the plunging ocean cliff near Manzanita, Oregon by three
transoceanic DXers (Chuck, Tom and I). A photo of the narrow, highly exposed
DXpedition site is posted at https://app.box.com/s/84h2dg1euqgkftzm0mhmbzld17z0t0yx
Exceptional South Pacific propagation combined with acceptable
summer weather, and breakthrough DU loggings were made on many frequencies. The
7 most exotic South Pacific DX catches made with the C.Crane Skywave Ultralight
radio and 17" DXpedition antenna are posted below, along with a brief
description of the station and reception conditions.
531 More FM Alexandra, New Zealand (2 kW) Very rare Kiwi R
& B music station heard for the first time in North America in June at this
location, it rarely sneaks through the more powerful (5 kW) Auckland Maori
language station (PI). This MP3 features a "More PM" ID 3 seconds into the
recording
558 Radio Fiji Suva, Fiji (10 kW) Listed as inactive in the
2015 WRTH and not listed in the current PAL, the station was heard weakly in
June at this location by Tom and I. This powerful (near S9) signal recorded on
the last day of the DXpedition features the station's typical Polynesian choral
music format, and is solid evidence that the transmitter has
been repaired.
558 6WA Wagin, Australia (50 kW) Relatively weak logging
made at the end of a session featuring Australian-slanted propagation, this
recording features the typical LR network male-female interview format and
announcer voices, with programming identical to that heard on the LR network
station 774-3LO 30 minutes earlier (there is an programming delay between
eastern and western Australia on the LR network). Fortunately, 6WA is the only
LR network station on the frequency. A new Ultralight radio worldwide DX
distance record at 9,137 miles / 14,704 km.
585 Radio Ngati Porou Ruatoria, New Zealand (2 kW) This
Maori-language Kiwi station a legendary reputation for weakness, and has only
been heard with FSL antennas at this Rockwork 4 site. The only was to identify
it is to match its Maori-language programming with late-night parallels on 603
or 765, and this is rarely possible. For some unknown reason wacky Kiwi
propagation on 8-9 boosted its signal up to a relatively healthy level, even
stronger than its 603 parallel recorded at the end of the MP3.
585 7RN Hobart, Australia (10 kW) The only Tasmanian
station ever to be heard with FSL antennas, this potent RN network signal on 8-9
was matched with the 576-2RN parallel for identity confirmation. The announcer
gives a laid-back introduction to jazz music, dominating the frequency
completely
585 2WEB Bourke, Australia (Presumed, 10 kW) During wacky
Australian-slanted propagation on 8-8 this signal featuring the Tokens' "The
Lion Sleeps Tonight" temporarily broke through 7RN's exotic music, and was not
parallel to either 576 or 603 (i.e. not 7RN nor Radio Ngati Porou). Since this
song is typical of that played in 2WEB's format, the evidence definitely points
to that station (which has been heard twice before at this location).
936 Chinese Voice Auckland, New Zealand (1 kW) Wacky ocean
cliff propagation boosted the signal of this very low powered Kiwi station up to
quite a potent level on 8-10, providing a good example of how almost every New
Zealand station can come into play when Cliff provides its DU signal boost
Many more South Pacific stations were received at the plunging
ocean cliff during the five day DXpedition, but these were 7 of the more
interesting ones. Thanks to my partners Chuck and Tom for information on their
loggings, and we do plan a full DXpedition report after all the recorded signals
have been reviewed.
73 and Good DX,

Hi Steve. Yes I have found that it seems to work well, being able to move the loopstick in different directions seems to allow better control over which signals are received. Paul On Thu, Aug 13, 2015 at 10:10 AM, Steve Ratzlaff ratzlaffsteve@... [ultralightdx] <ultralightdx@...> wrote:

Apparently the capacitance of the long coax cable from the loopstick to the radio doesn't prevent the radio's DSP from tuning to the top of the MW band? That's the first time I've heard of anyone doing that before! Steve On 8/12/2015 3:15 PM,

Ultralight DXing Report - Denison Road Scenic Lookout

Date: 12/08/2015 Time: 16:10 – 16:50 Local Location: Denison Road Scenic Lookout Launceston Radio: 7.5” Loopstick Tecsun PL-360 Total stations logged: 27 New stations logged: 0 Notes: Recently while out driving I came across the sign (first photo) for a lookout that I had not heard of before, I made a mental note to return and check it out. Yesterday I had a couple of hours of spare time so decided to go and undertake a portable ultralight DXing session from this location. I parked my car and set off up the rough track, I arrived at the seat (second photo) and thought “this can’t be it” so kept going, soon the track ended so I walked back and set up on the seat. In the 40 minute period I logged 27 stations which were a mix of Tas, VIC, NSW and some SA stations. No new stations were logged and overall I was not that impressed with the location or the medium wave stations I heard on Medium Wave. I also did some listening on the shortwave bands and logged the following stations: 7405KHz Radio Marti 7455KHz RMI 7555KHz EWTN 9790KHz Radio France International 11520KHz EWTN 11580KHz RMI 11625KHZ Vatican Radio 11775KHz China Radio International 11850KHz Radio Free Europe 13635KHz Voice of Turkey 15595KHz Vatican Radio 15700KHz Radio Romania International 17615KHz China Radio International Photos: http://ultralightdxing.blogspot.com.au/2015/08/ultralight-dxing-report-denison-road.html |

Oregon Cliff (Rockwork 4) Ultralight DU's for 8-10 (Conclusion)
Hello All,
I wish that Nigel and Nick had a chance to sample the New Zealand DX at the
ocean cliff this morning-- which was primarily a "challenge" of choosing which
S9 signals to record. The Australian signals seemed to fall off of a
cliff compared to yesterday (um, maybe I should use a different term?), leaving
the Kiwi signals to run wild all over the band.
531-More FM (2 kW on the South Island) made its first appearance during
this trip with a near-S9 signal around 1315, while 936-Chinese Voice (1 kW in
Auckland) had a similarly potent signal around 1325. 774-Radio Sport was a solid
S9+ with its relay of American-accented Fox Sports News at 1248, while the Maori
language twins 603-Waatea (5 kW) and 765-Kahungunu (2.5 kW) both sounded like
big guns all session long. The star of the session was an obscure station
outside of New Zealand which suddenly came through with a near-S9 signal of its
own, though-- 558-Fiji. Pounding through with a signal that sounded every bit as
strong as the listed 10 kW, its Polynesian choral music ran wild over the
obscure Kiwi station Radio Sport around 1256. Listening to its distinctive music
at such a potent volume brought back fond memories of the venerable 639-Radio
Fiji One signal of old, which was a coastal regular back around 2009 even on a
hot-rodded 7.5" loopstick Eton E100.
This was the last session of the August Rockwork 4 DXpedition, and it was
my great pleasure and honor to have enjoyed exceptional Australian and New
Zealand propagation together with my DXpedition partners, Chuck and Tom. When
all of the DU signals are reviewed and identified I'm sure that all three of us
with remember this ocean cliff DXpedition with the fondest of memories.
531 More FM Alexandra, New Zealand (2 kW) Very rare South Island Kiwi
with potent R & B music and male "More FM" ID 3 seconds into the
recording
558 Radio Fiji Suva, Fiji Distinctive Polynesian choral music near S9
level at 1256; signals far improved from late June DXpedition
567 RNZ Wellington, NZ Female-voiced movie review at usual S9+ level
at 1228; strongest Kiwi of the session
603 Radio Waatea Auckland, NZ Maori vocal music with S9 peaks //
equally strong 765-Kahungunu at 1234
774 Radio Sport New Plymouth, NZ 5 kW Kiwi station with S9 relay of
American Fox Sports news at 1248-- way over anemic 3LO
936 Chinese Voice Auckland, NZ (1 kW) Wild Kiwi propagation boosted
even this obscure station up to a potent level at 1225
1008 Newstalk ZB Tauranga, NZ Talk program booming in at (you guessed
it) S9 level at 1319; its best signal of the DXpedition

Re: All-Time Worldwide Ultralight Radio DX Distance Record Broken
Allen and Guy,
Thanks very much for your generous comments on the reception of 558-6WA.
The signal was recorded on a whim at the very end of the sunrise session, with DU propagation collapsing on all other frequencies. I was curious how this signal could possibly be so persistent, and why it seemed to be riding some unusual propagation. But I thought nothing of it at the time-- in fact, Chuck and I were having an end-of-session discussion during the recording, since we both figured that DU propagation had fizzled out.

4aAll-Time Worldwide Ultralight Radio DX Distance Record BrokenSun Aug 9, 2015 6:59 pm (PDT) . Posted by:dxergaryHello All, My transoceanic DXing buddy Tony King of Greytown, New Zealand (the "Kiwi X-Band King") shocked us all with his phenomenal reception of 1 kW 1690-CJLO from Montreal, Quebec about a year ago, breaking the all-time Ultralight Radio DX Distance record (at 14,631 km / 9,091 miles). But as Tony knows very well, the South Pacific-- North American propagation pipeline works both ways :-) Yesterday morning at the Rockwork 4 ocean cliff near Manzanita, Oregon a persistent Australian station was hanging around on 558 kHz just as propagation was crashing, ma king me wonder exactly where it was coming from. After some investigation of the MP3 by my DXpedition partner Chuck Hutton he determined that the format matched that of Aussie LR network parallels on 774 and other frequencies, leaving only one possibility on the frequency-- 558-6WA in Wagin, Western Australia (at 14,704 km / 9,147 miles). This was received on a C.Crane Skywave model boosted by a 17" FSL antenna. Although this 50 kW ABC station is nowhere near the type of exotic 1 kW catch that Tony had with 1690-CHLO, I'll take it anyway! 73 and Good DX, Gary DeBock (DXing at the Rockwork 4 ocean cliff near Manzanita, Oregon, USA) |

For those interested, 558-Fiji had an S9 signal on peaks during this morning's (final) Ultralight DXing session at the Rockwork 4 ocean cliff near Manzanita, Oregon. This was much stronger than it had been heard during the June DXpedition. https://app.box.com/s/vq9768fgfvqdjeuc30dtqkt2m6p9u7rh 73, Gary DeBock 7.5" loopstick C.Crane Skywave Ultralight + 17" FSL antenna |
