A VALUABLE FIELD DAY ACCESSORY
Locked
 
|
Headphones and Field Day have been yoked since time immemorial. The
K3's ability to output its audio into both headphones and speakers simultaneously has been a boon to those FD sites that encourage visitors. It permits the operator/logger to use headphones while visitors can monitor the action through speakers. The problem lies in the volume levels that each of the participants require (or don't require). This is especially true when multiple transceivers are occupying the same tent/trailer/room, etc., and each have their own group of listeners. Cacophony is not the goal here. As veteran Field-Day clubs have discovered over the years, a valuable accessory is a multi-outlet headphone-amplifier with individual volume controls for each headphone. For several years we have used a Behringer Amp800 (https://www.amazon.com/Behringer-AMP800-Four-Channel-Headphone/dp/B000KU87SM) at our CW position. Lately, we have also been using a Rolls HA43 (http://www.rolls.com/product.php?pid=HA43) which is smaller and easier to operate. Neither are bothered by stray RF. I have no vested interest in either. There are similar products under various brand-names. The Behringer can be had for around $70 and the Rolls for $50 from numerous online vendors. The Behringer only accepts 1/4-inch phono plugs while the Rolls has dual input jacks to accept both 1/4-inch phono and 1/8th-inch plugs. This is another reason I like the Rolls as no "tweenies" (adapters) are needed. Uses might include . . . A neophyte with an unconnected laptop, wearing his own headphones, entering call signs/exchanges into a practice logging program without disturbing the main operator. Or the next shift warming-up before assuming the operator's position. Or someone merely wanting to seriously listen for a while without being bothered by the inevitable traipsing in-and-out of visitors, kibitzers, the lost, the lonely, the huddled masses yearning to be free. Both of the above units accommodate up to four headphones. 73, Kent Trimble, K9ZTV Mid-MO Amateur Radio Club Jefferson City, MO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

That's why it's called a "headphone amplifier."

Those types of headphone distribution amps can often be found at music stores, like Guitar Center, Sam Ash, etc. They might also have some compact amps with speakers, too.

Guessing there's a really good chance that we'll have one in 2018, too.
Just add the tip to your list for next year prep.... Of course, you can likely get it to you from Amazon by Saturday... Amazon Prime is awesome... 73, ______________________ Clay Autery, KY5G On 6/20/2017 4:31 PM, garyk9gs wrote: > All well and good..but FD is in 4 days. > > > 73-Gary K9GS > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Actually, thanks. I have been looking for something like this for a while, and since they are available locally, it might be a good trip on my way to the FD site.
Does anyone make a distribution / intercom box that allows the two ops to talk between themselves without removing their headphones? One with a switch to select one of the microphones to go to the rig might be an interesting box / project as well. - Jack, W6FB > On Jun 20, 2017, at 2:44 PM, Raymond Sills <[hidden email]> wrote: > > Those types of headphone distribution amps can often be found at music stores, like Guitar Center, Sam Ash, etc. They might also have some compact amps with speakers, too. > > > 73 de Ray > K2ULR > KX3 #211 > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to [hidden email] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

I believe there was a design for a device of that nature in a recent (last 10 years) ARRL Handbook. I don't have time to search the library just now. 73, ...

Just order you needs from Amazon today or tomorrow and have it by
Friday. I ordered my Koss SB 40 headset/mike on Friday and it was delivered Monday. No expedited shipping either. 73 Bob, K4TAX On 6/20/2017 6:05 PM, Clay Autery wrote: > Guessing there's a really good chance that we'll have one in 2018, too. > Just add the tip to your list for next year prep.... > > Of course, you can likely get it to you from Amazon by Saturday... > Amazon Prime is awesome... > > 73, > > ______________________ > Clay Autery, KY5G > > On 6/20/2017 4:31 PM, garyk9gs wrote: >> All well and good..but FD is in 4 days. >> >> >> 73-Gary K9GS >> > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to [hidden email] > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

RE: "If you find one, let me know"
Walter, There are portable aircraft intercoms available from aviation suppliers like Sporty's Pilot Shop, and possibly from Amazon, too. They allow the passengers to talk to each other, and listen to the radio communications if they desire. The pilot can listen to only radio communications, or he can listen to the passenger chit-chat if he wants, with communications audio from the radio overriding that. The pilot's mike goes to the radio for communications purposes if he pushes the PTT switch, or to the passengers chit-chat if he doesn't. The biggest problem with these intercoms is that they are designed for carbon microphones and higher impedance headphones than we normally use. I have seen circuits for converting stereo headphones and dynamic/electret microphones to work in aircraft, but not so much in the opposite direction. That won't be a problem for the resourceful hams, but I suspect they won't work right out of the box. Just a thought.

I just ordered the Amp800's smaller cousin, Behringer Microamp Ha400
Ultra-Compact 4-Channel Stereo Headphone Amplifier <https://www.amazon.com/gp/product/B000KIPT30/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1>, for exactly this purpose.
