DX LUVER,
FIRST - Most Headphones today are made for Music Listeners who want High Fidelity Sound Reproduction. For Radio use this means FM Stereo Sound. SECOND - For AM/MW and Shortwave sound reproduction a 'quality' Headphone that can be used for FM Stereo Listening will do the Job OK provided that it has a good long term Wear-ability Factor. For AM/MW Shortwave DXing the Headphone's Wear-Ability-Factor is Equal to the Headphone's Sound Reproduction Qualities. For Me - The Headphone's Wear-Ability-Factor is usually an "ODD" Number and Rating: #1 = POOR - Less that One Hour and My Ears are 'Sore' and My Head 'Aches'. #3 = GOOD - After Three Hours My Ears are getting Sore & Sweaty and My Head is starting to Ache form the pressure of the Headphones. (Lets me know it time for a Break from the Listening to the Radio.) #5 = GREAT - After Five Hours My Ears are NOT Sore and My Head is NOT Aching. (This usually means that I Missed getting up from the Radio/Receiver and having a Meal ![]() THREE - About Headphones Sound Reproduction "Qualities: "IF" you have a good AM/MW Shortwave Radio/Receiver that is a real DX Machine with both Signal and Audio processing features. Then the Radio/Receiver will be the "Limiting Factor" in the Audio Chain and the Sound Level and Audio Reproduction that you Hear on your Headphones will be a faithful reproduction of what is being provided by your Radio/Receiver and nothing more. IMHO: Personal Comfort and Wear-Ability is my primary Concern in 'selecting' a set of today's quality High Fidelity Headphones for Radio Listening and DXing. TIP: Go to the RadioShack Store and Put them on your Head (Not 'plug' into anything.) and then walk around the RadioShack Store for a Half-Hour and get the Feel of the Headphones on your Head. NOTE: If you are not 'comfortable' Wearing the Headphone with out any Sound for a Half-an-Hour; then they are not for you [.] TBL: I trust to my Radios/Receivers to giving me the Sound Level And Audio Reproduction that I need for Radio Listening and DXing. BONUS - If you should want to do some FM Stereo Radio Listening from a Radio that only has a Single Speaker / Mono-Aural Sound. Then a set of quality High Fidelity Headphones are really Great for doing some enjoyable Stereo Sound Listening via FM Radio. mkia ~ RHF .. .. = = = (Dxluver) wrote in message = = = ... SPECIFICATIONS: • Frequency Response: 20-20,000 Hz • Maximum Input Power: 100 mW • Impedance: 60 ohm • Nominal Sensitivity: 98dB • Total Harmonic Distortion: 0.2% at 95 dB SPL, 400Hz and 1 KHz Are those good specs though RHF for dxing? Your 'best' DXing Specs are the ones for your Radio/Receiver. Anyone in the knows here? I don't want to get a pair of phones that aren't good for long sessions of dxing. Then - Think Comfort First. produce dynamic sound and are perfect for listening from your computer, MP3 or CD player I use none of these, nor do I forsee it happening in the future. I'll write down that cat.# and take a look. See the Tip Above. ****right now though the most important thing to me is getting an 'extension jack' for my external antenna jack that I can leave plugged in.***** FWIW: RadioShack sells 3Ft-6Ft Mono & Stereo Audio Extension Cables that do the trick. You can use them as is or modify them with a small Utility Box that several Audio Output Jacks to meet your specific Audio 'connection' needs. TIP: These same 3Ft-6Ft Mono & Stereo Audio Extension Cables can be used for the External 1'8" Antenna "INPUTS" that are use on many 'portable' AM/FM/Shortwave Radios. Leave it connected to the Radio and connect and disconnect the Antennas for the other end of the Extension Cable. (Save the Radio's External Antenna Input from 'wear-an-tear'. Again you can modify this Cable with a small Utility Box that several Antenna Input Jacks and Terminals to meet your specific Antenna 'connection' needs. Also, you can include some circuity to provide a small level of Radio/Receive PROTECTION from EMF and ESD.

REMEMBER: "The Shortwave Antenna is 55.5% of the . . . Radio/Receiver and Antenna/Ground Reception Equation" http://groups.yahoo.com/group/Shortw...na/message/288 A Shortwave Antenna is "Equally" Important for Good Reception [.] .. .. iane ~ RHF ..
