Kevin & Brett:

I discovered yesterday that I'd purchased an Olympus Digital Voice
Recorder WS100 a couple of years ago to record meeting notes. Because
it didn't do well I put in a drawer and forgot it. I'm going to try
it out this evening with my SRF-T615.

I'm also going to check out the Sony ICD-UX70 MP3 stereo recorder.

Thanks for the information.

Richard Allen.

P.S. for John Bryant: Be thankful you are in Washington state. I
just left Stillwater and it was 100°. According to KOSU, it was 102°
yesterday. -30-

FM DXers would certainly benefit from something equivalent to the
spectrum-capturing receivers such as the Perseus and RFSpace SDR-IQ
that are all the rage with serious AM broadcast band DXers.

Of course that technology presently strains at the storage of 800 kHz
of bandwidth, so grabbing any significant chunk of the FM band for
later analysis will require a quantum leap in receiver, PC, and hard
drive capabilities.

I'm sure the NSA has stuff like this already, but it will be quite a
while before Joe Ham does.

I dunno. I just can't bring myself to use an ultralight when the Es
is in for FM DX. Gotta milk the opening for every station you can
and that usually means the top shelf radios. I got in on the Es from
yesterday and bagged 9 new stations from Oklahoma, Tennessee,
Missouri and Arkansas, but I used the car radio since these things
always happen when I'm at lunch.

Using an ultralight during a strong tropo opening might be more
interesting since you aren't under the same time constraints as you
are with short-lived Es. You have to play around when the tropo is
in, unlike when the Es is in.

The Olympus seems to get 15-20 hours on a single AAA battery - I usually
just let it run for an hour or so at a time and get quite a few sessions
out of it.

I've been using it for several months, off and on, with the original
single
AAA battery. Not sure of the total record time on it, I would estimate
two-three hours (there are ~ 45 files, each one 2-5 minutes long). Seems
pretty energy thrifty,

Hi Richard,

I've gone the minidisc route in the past. I've pretty much gotten
away from it due to the noise that
all my MD recorders create on AM. This year, I'm trying a combination
of the Sangean DT-200VX ultralight radio and Sony ICD-UX70 MP3 stereo
recorder. The Sony recorder weighs less than 2 oz., has 1GB memory,
records at 128 kbps stereo and has a line-in jack that can
intelligently take either an external microphone or the line out
direct from the radio - no transformers or impedance adapters needed.
I plug a stereo splitter from Radio Shack into the headphone jack of
the radio and run my headphones out of one side and a stereo patch
cable to the Sony out of the other.


The Sony is absolutely the perfect mini-DX recorder - it auto-names
the files including the date, and has a USB
plug to transfer the recorded MP3 files to the computer directly from
the recorder. All I have to do is
write down the order of the recordings and I can match the times and
frequencies up later.


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.

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

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!

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.

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.

_________________

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...
