Red Wave Radio

I am SO frustrated. For the second day in a row I've been unable to make
out Radio Exterior de Espana's newscast over the speaker of my FRG8800.
I've tried SSB (cuts down the static), the tone and the attenuator but
they seem to be just below audibility level. I'm gonna follow some
advice I was given here a couple weeks ago about using headphones. But I
want to get good quality ones, not cheap jogger's ear buds. What brands
of headphones do you guys use?

El cheapo old Archer Dynamic 16 ohm headphones. I have two pair. They are
great for SW.

Very good question.

I have tried most out there & here are my favorites.

For maximun intelligibility.....Heil Proset . Will make a Hiiisssyyy radio
sound really hiiisssyyy.

For maximum comfort.......Yaesu YH-77  Highs are rolled off.

I wear reading glasses most of the time in the radio room & the smaller
headphones....like the YH-77..... are the most comfortable.

The Kenwood HS-5 is a good set as well if you find them comfortable.

73,   Ken

   Sennheiser, beyerdynamic, David Clark.

   For intelligibility and isolation, David Clark. Hands down.

   Ain't cheap. Worth every penny.

This site specializes in everything headphones -- from ear-buds to
top-of-the-line $1000 audiophile headphones, and has reviews and advice.

I like mine.

Sennheiser HD-580 headphones and Etymotic ER4P earphones.  Neither could
be fairly described as cheap or appropriate for jogging.  High end
response might be a bit too good for really comfortable SWL.  I also
have a pair of cheapo RS mono headphones that I bought years ago.  
Response and range are both horrible, but these are "features" that work
fairly well for SW.

I have two also,  forget the name of one and it is in the closet with the extra
gear.  It has a small break ina connection that I have to fix but they are VERY
cushy,  almost like putting your ear in a pillow.....I really need to fix them.

But I use my trusty Optimus Pro 40's,  I've used them so much that the inside
foam has worn out so I've had to break out the electrical tape and do a nice
tape job.  They are very comfortable.

But yes I need another pai,  matter of fact,  I have to check the thread I
started on those new titanium ones from Radio Shack.  I'll have to say,  you
KNOW when you put them on that they are expensive.  Hopefully the DX
performance would be the same.

Sennheiser HD590 - just a bit noisy on the 7600G, 120 ohms vs. maybe 16
ohms output impedance. Had to return a pair of Koss KSC-50s (then
Sennheisers are a tad big for mobile use, though very comfortable),
hopefully I'll get a replacement in this lifetime.

I always run audio out of my NRD-525 through a Kenwood HiFi-amp with
equalizer and take  my AKG K-240Montor headphones when neccecary. Also 2
analog audio filters in series if needed (bandpass, notch, peak).

For HiFi headphones, Grado is superior to any mass-market brand.

I wouldn't recommend hi-fi headphones.  The response of such covers a wide
range of frequencies, and would likely exacerbate low frequency rumbles,
hums,
etc.  Similarly, one shouldn't have need for the crisp high-frequency
crackles of
clicks, crashes, etc that such hi-fi phones would deliver.  Nothing would
seem
better than a bonafide pair of military-style metal disk phones that
responded
to voice frequencies, steeply rolling off below 100 Hz and above 1000 Hz.
In
this regard, I have used an old stenographer's caliper headset which covered
just
about that range of frequency for good result.  On the other hand, if I am
in the
mood for listening to music over a superb signal, then I use my standby
JRC-ST-3
headset, having performed some internal surgery to bypass the 8:300 ohm
xfmr,
and rewired the earspkrs to a DPDT switch providing a switchable choice of
'in-phase' or 'out-of-phase' listening ... a dramatic effect. Try it.

Now you've got me thinking... :-) I have two Grundig portables, a YB400 and
an S350 and the YB comes with some earphones (which although sound
reasonable, I don't like - I don't like ear buds). But now, here is my
puzzle: what is the recommended earphone impedance for those radios? I
couldn't find it specified anywhere! Is there some sort of standard one? If
yes, do all earphones on the market have that same impedance?

And about the response frequency, it appears that hifi earphones are not
suitable for SWL. What is the suitable frequency range then? (70Hz-11KHz
maybe?) Back in high school, I used to use (tele)phone speakers quite
successfully in my DYI HF projects. But then we had phones with detachable
speakers ... They were with very narrow audio response and with quite a
high impedance (500Ohms ?).

The impedance of the headphones for a shortwave receiver is not that
important, providing they are not high impedance, such as several
hundred ohms, which would significantly lower the volume. Most
headphones will be below 50-ohms. As for the frequency range, shortwave
broadcasters don't transmit much audio above about 5-Khz, so that would
be a good top end for the headphone response. This is well below the
full fidelity range of Hi-Fi headphones, which is why they are not a
particularly good choice for shortwave, unless you have significant
hearing loss on the high frequency end of the audio spectrum.
