I was surprised to read that the brand of headphones mentioned most
was...Radio Shack (and various incarnations thereof, like Archer and
Optimus). So I went to my local RS and quickly located the mono
headphones. There was no price posted so I had to ask the guy behind the
counter-with tax I paid about $15. He asked if they were for scanner use
and I said yes, not caring to explain what a shortwave radio is to him.
Anyway, the first thing I discovered with the headphones is that I was
overdriving the 8800's small speaker-I had to turn attenuation up and
volume down to get a listenable signal on the headphones. I agree that
headphones make for a much more intelligible signal.

TK,

Many modern AM/FM Shortwave Radio/Receivers now use a Stereo
Headphone Jack that is 'wired' for Dual Mono-Aural Outputs to
drive both the Left and Right Sides of the Stereo Headphones.

NOTE: This is done because most Headphones today are designed
and Manufactured 'wired' for Stereo {Separate Bi-Aural} Sound.

Check your Radio/Reciver to see what it 'wired' for:

[ ] Basic Mono-Sound Headphone Jack
= = = Usually older radios and receiver

[ ] Stereo-Sound Headphone Jack
'wired' as Dual Mono-Aural Outputs.
= = = Usually newer AM/SW/SSB/CW Radio/Receiver that
does NOT have a built-in FM "Stereo" Radio Section.

[ ] Stereo-Sound Headphone Jack
'wired' for Stereo {Separate Bi-Aural} Sound.
= = = Usually newer 'portable' AM/FM/Shortwave Radio
that does have a built-in FM "Stereo" Radio Section.

TIP - If the Radio/Receiver HAS a built-in FM "Stereo" Radio
Section: Then Expect that the External Speaker Jack, Earphone
Jack, Record Output Jack and Line Outs are all 'wired' for Stereo.
CONVERSE - If the Radio/Receiver does NOT has a built-in FM
"Stereo" Radio Section: Then Expect that the External Speaker
Jack, Head/Earphone Jack, and Record Output Jack are all 'wired'
for Dual Mono-Aural Sound.

TK,

By "8800" I 'assume' you mean a Yaesu FGR-8800.
FRG-8800= http://www.rigpix.com/yaesu/frg8800.htm
FRG-8800= http://www.dxing.com/rx/frg8800.htm
http://www.yaesu-museum.de/Galleries.../frg-8800.html

IIRC: My Yaesu FRG-7700 has a Headphone Jack on the front of
the receiver that is 'wired' for Dual Mono-Aural Outputs to
drive both the Left and Right Sides of the Stereo Headphones.

NOTE: To Me, the Headphone's Right Side sounds louder
then the Left Side.

ALSO - On the 'front' of my Yaesu FRG-7700 is a Mono-Aural
RECORD Output Jack.

PLUS - At the 'back' of my Yaesu FRG-7700 is an Mono-Aural
External Speaker Jack.

I would assume that the FRG-8800 and the FRG-7700 have the
same basic Audio features.

I'm using the headphones on a Yaesu FRG8800 tabletop receiver. It has no
FM (stereo or mono) of course so the jack should be mono. I've
experienced no problems.

Which of these headphones is the best for SWL ? :
(from RadioShack online catalog)

Koss® Limited Edition 50th Anniversary PRO-4AA... $99.99 (Cat # 33-1217)

Sennheiser® Full-Sized Headphones $69.99 (Cat # 33-1223)

Philips® Noise-Canceling Headphones $69.99 (Cat # 33-1224)

RadioShack Stereo Headphones with Titanium Dia... $39.99 (Cat # 33-1182)

Stereo Headphones with Titanium Diaphragms $39.99 (Cat # 33-1222)

Closed-Cup Stereo Headphones With Dual Volume ... $21.99 (Cat # 33-1176)

This last one looks quite reasonable to me! Its characteristics are :

20-20,000HZ
32ohms
sensitivity 98dB
11/2" ferrite speakers
rated power: 50mW
max power 80mW

Also the Philips one is tempting. Anyways, what is your opinion?

Radio Shack may still have a large mono to small stereo adapter. I
bought one years ago and it works perfectly on my FRG-7700 , FRG-7 and
KW R-5000. I have the KW full over the ear headphones but I find they
get heavy in a hurry. I much prefer the smaller walkman type phones.

I'm curious what they'll say also Nicolae.
