Heard on Eton E-100 barefoot at Conimciut Point Park Warwick R,I. .

Opening Notes: Today was the big one. A massive tropo duct opened into the gulf coast. I found myself smack in the middle of it. The dial was peppered with stations UNIDED mentioning tennesee, Missisippi, the gulf coast including a weather report from the gulf coast. UNided on several freqs 94.7 107.5 ,105.7, 103.9 and a few others. uNFORTUNATLY  i was called to WORK and had to drop this massive seesion. i have at least one logged and possibly one or two more IDed but the notes need to be picked thru. The single complete logging below alone sets a new FM DX record. for me. 

New Logging:

94.9 WKSJ Mobile Alabama 12:01 PM EDT heres another 50 minute music maraton on 95 ksj also heard a mobile alabama weather report earlier. battling i out with WHOM Mt Washington for channel ownership. 7/22/08

Hi Brett:

On the Olympus model I use, if I go from the highest quality setting to
the medium quality settings, the emitted noise disappears, and at around
44,000 kbps, the fidelity still far exceeds what I need for DXing. Plus,
the files take up about a third of the room on the old hard drive and are
easier to edit.

It's good to know models don't need impedance matching - when the Olympus
dies, hello Sony!

The Sony introduces a little noise on AM but if I separate it from the
radio
by a foot or two of cable, and
move it with respect to the antenna, the noise drops to almost nothing.

very interesting read on your progress on the updated version of the
srf39 and a digital display.

i'm interested in where you got the vernier and which version of the
AADE display versions did you buy? it appears we would need to ask
Neil to modify one for us.

I THINK THAT IT IS HIS VERSION 1, BUT YOU'LL HAVE TO TELL NEIL THAT YOU ARE ORDERING ONE FOR THE SRF-39 series and he will pick the correct one and DO THE SPECIAL PROGRAMMING.  I PAID THE EXTRA $15 AND GOT THE TWO-LINE DISPLAY

i found a vernier at ocean state electronics that is similar but is
4:1 ratio in 180 degrees rotation at $15 plus shipping. your article
sort of implied that a higher ratio may be desirable?

YES, I SHOULD HAVE MENTIONED IN THE ARTICLE THAT THE VERNIER CAME FROM OCEAN STATE, TOO. THEY ARE PRETTY HARD TO COME BY.  AND YES, I WISH THAT THE REDUCTION RATIO WOULD BE ABOUT DOUBLED.  I THINK THAT MIGHT BE AT LEAST PARTLY SOLVED BY A LARGER DIAMETER TUNING KNOB THAN THE ONE THAT I AM USING.  ALSO, THE VERNIER WAS QUITE STIFF WHEN I RECEIVED IT.  I SUSPECTED THAT IT MIGHT BE FROM TOO THICK A LUBRICANT, SO I GAVE IT A THOROUGH BATH IN WD-40 AND NOW IT IS QUITE FREE.  I WANTED IT FREE SO THAT I COULD TELL CLEARLY WHEN I HIT THE STOP AT EITHER END OF THE TUNING CAP.... IF NOT, THE MECHANICAL ADVANTAG OF THAT VERNIER DRIVE COULD DESTROY THE TUNING CAP IN A HEARTBEAT.



i'm still looking for some srf39's or may open up one of my 59's to
see whats involved with using it. the picture i found on the web shows
the tuning cap with the gear and knob removed leaving a shaft with
flats on it that may lend itself to connection to a vernier in a
different way than the 39

STANDARD 39S SEEM TO STILL BE QUITE AVAILABLE ON EBAY... BUT THE FPS SEEM TO BE GONE. BOTH HAE THE SAME DIAMETER TUNING WHEEL. I'M NOT SURE ABOUT THE OTHERS.



thank you for the write up and any other help you can pass on.

Re: What is best method for recording DX from an ULR?

satya@...
 

Hi Richard:

I use an Olympus WS-300 flash drive (solid state) recorder and love it,
since it's samll, runs about 20 hours on a single AAA battery, and can
immediattely be loaded onto the computer for editing and archiving.

How I solved the impedance and overload problem (some of you may laugh...)
was:
- take a patch cord with 1/8" stereo male plugs and cut it in half
- on both resulting pieces, strip the leads and tie the two insulated
"positive" leads together on each, leaving a single combined "positive"
lead plus the braid as the negative. Monophonic is fine for my DXing
purposes, but the recorder needs to see a stereo plug.
- Recombine the two pieces into a single cable, putting a 0-10K resistor
in series between the positive leads. The two negative braids are
directly tied together.
- I put a 25 ohm resistor across the positive and negative, which
apparently allows the recorder to "see" an impedance it likes. Plus, it
absorbs a lot of energy which otherwise distorts the recording: just the
10K pot was too iffy on finding a good recording level.

I plug one end into the receiver and the other into the MIC jack of the
recorder. I then plug my headphones into the recorder so I can listen as
I record. The Olympus has an LCD "VU meter", which helps, although my
ears are very good at telling if I'm overloading or underdriving the
recorder. Underdriving produces digital artifacts which sound like a
light (and annoying) wind chime when you play it back.

Hope this helps!

I have a question or two on recording DX from a ULR.

I realize the recorder has to share the receiver's audio output with
the headphones. But how do you handle the impedance mismatch between
the receiver and recorder?

In keeping with our ultralight theme, do you prefer a mini-disc or
solid-state digital recorders over cassette tape? Does anyone have
any recommendations in this area? Thus far I leaning toward a
mini-disc recorder which I understand is already obsolete.

Thanks for the help.

_________________

Ordinarily, I use an impedance matching transformer to match from most radios. Your typical headphone output is 4-8 ohms; your typical computer sound card wants to see something in the 5000-10000 ohm range ideally. I've found that 100, 2000 or 2500 ohms output is usually sufficient.

HOWEVER, there's another issue with ULR's which doesn't seem to exist even with my Sony 2010, and that's transmission of both monitor and CPU noise. Even with a 6 or 10' extender to get the ULR physically away from the computer so as to eliminate radiated noise, I still have way too much of it getting through, even using both my matching transformer and also a RS ground loop attenuator.

I haven't managed to correct this so far...

and tell me .........

London Ontario CANADA has 3 AM Radio Stations.........WHAT ARE THE
FREQUENCIES OF THESE 3 STATIONS??????

The first person who gives me the answer.....wins the Promo Stuff!!

I'll even pay the postage to get these items to you!!

It's titled "Building and Operating the Digital Sony SRF-39" and its located on the third (last) page of files in our Ultralight Files Area of dxer.ca.

Re: wznz 1460

Hello Richard,

Congratulations on your loggings of WZnZ-1460 and KSCO-1080.
It's always fun to log stations on both coasts.

Your report reminded me of my most exciting domestic logging
ever-- a bizarre sunset skip logging of KFWB-980 in Los Angeles
(5,000w at the time) as a 20-year old Navy sailor in Mayport, FL (in
1973), using a Sony TR-6400 portable. From that time on, I have
always tried to DX near the ocean, hi.

73, Gary

New FM Logging & Notes 7/18/08

Norbert 26 <starship_2001@...>
 

Heard on stock Eton E-100 barefoot at Conimeicut Point Park Warwick R.I.

Notes: This logging was a strong short haul tropo opening out to Cape Cod.. Although even the slightest tropo enchanment will bring in the stronger Cape market stations this one is very hard and rare .

Notes 2: Earlier this AM i reported n HD detection on WWLI 105.1 . An absense of whining on 104.9 and 105.3 was noted on the Eton E-100 therefore WWLI IBOC is off at this time or at least was earlier today.

when i get the chance.In regards to audio,i disagree with Gary though
this is a matter of personal opinion perhaps.My audio on the FM on the
E-100 is acceptable for a ULR when using the Sony headphones i got
with my SRF-M37W.I have fm dx receptions from Oklahoma,Texas,Kansas

Gary.....I can confirm what you say about placing the whip closer to an

While I was on my Cruise 2 weeks ago....I did a lot of FM DX'ing

that by
Laying the Whip Antenna up against the METAL RAILING of the balcony

think if one could attach the whip to a Good FM beam.......in a

with few locals to avoid overloading........you would be able to

some pretty good FM DX with this little ULR Radio!!!!
