Has anyone used a Bluetooth adapter for wireless headphones / headset with
the K3? Any recommendations or suggestions?

In reply to this post by Yngvi (TF3Y)
I have been using an inexpensive adaptor from Amazon for several weeks now. Can't say what it is as in a joint effort a friend bought two adaptors after I suggested it might couple to his hearing aids and I later bought inexpensive headphones for both of us. Tag on back says model H-366T. Hangs toward the ceiling in the Ham shack and I can listen in the den if I like. Very nice to be able to move around the shack without being entangled in a cord. Has mic capability as well but haven't looked into that yet.

I have 2 APC UPS devices - I moved one's 7 AH battery to an external container where I have three of them in parallel. That UPS runs the cable modem, router, and cordless phone system. The other one runs my desktop computer and accessories. Because of the type of battery in the machine, I would have to do serious soldering to attach external wires, which would void the warranty. My standby power mentor/guru explained to me quite a few years ago that given a large enough battery source, the limiting factor in most consumer-grade UPS is the heating of the electronics. Both of those UPSes are running at about 15% of "advertised capacity" which, according to APC's runtime curve, extends the run time by a factor of 10. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ------------------------------ Message: 4 Date: Thu, 31 Aug 2017 23:56:39 -0500 (GMT-05:00) From: Mike Morrow <[hidden email]> To: [hidden email] Subject: Re: [Elecraft] KX2, spy radio Message-ID: <[hidden email]> Content-Type: text/plain; charset=UTF-8 Here's a 1970-era small western world 'clandestine' set called the AVCO TAR-224A: http://www.cryptomuseum.com/spy/tar224/ It's about three times the bulk of the KX3, which is very small for the era and not too large even by today's standards.

I had a SmartUPS 750, and it was very bad. Put out crud all the way from VLF to VHF. I threw it away in the end. In the shack I use a much older APC Back-UPS 500 for the computer, which doesn't seem to cause any problems. I've had to replace the battery every 3-4 years, but that's to be expected. 73, Richard G4DYA ------------------------------ Message: 9 Date: Fri, 1 Sep 2017 20:04:58 +1000 From: Glen Torr <[hidden email]> To: Elecraft Reflector <[hidden email]> Subject: [Elecraft] The times they are a changin.

The real use of SSB came when General LeMay of SAC adopted it for their world wide HF communications network and propagation conditions during that time were so good that it was almost impossible NOT to communicate anywhere you wanted to with SSB.

I have an Elecraft K3, P3, KAT500 & KPA500. I want to operate somewhat portable with the K3, P3, monitor and laptop, buddipole on SSB and digital modes on Field day, and demonstrations on outings to community events (like festivals, etc). My options, I?m considering are: 1) Honda 2000i gasoline generator 2) Yamaha EF2000iSV2 (with propane option) +++++++++++++++++++++++++++++++++++ 1) Deep Cell 12v 100amp battery (brand, model, control charger?) 2) Lipo battery (brand, model, control charger?) 2) appropriate solar power panels and controller charge for either of the above battery (brand, model, adapters?) ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ My questions: 1) Is it best to go with the generator option; and if so, which of the two choices above? Any outstanding reason for this option, and choice of the two? 2) Is it best to go with the Battery, and solar option; why? Is there reason to choose the Lipo over the Deep Cell batteries? I am concerned over the choices about battery voltages and amp?s needed to operate as stated above. It?s noisy but the generator option seems on the surface much simpler for setup. However, from the perspective of demonstration of Amateur Radio today, the solar and battery option appears to be more demonstrative of the state of Amateur Radio today. Being 77 yrs old, I don?t want to get over my head in technology (though I love such). Thanks for your thoughtful recommendations.

Taylor, WB6UUT" <[hidden email]> To: [hidden email] Subject: Re: [Elecraft] UPS Can Be a Noise Source Message-ID: <[hidden email]> Content-Type: text/plain; charset=utf-8; format=flowed Keep in mind that by code, a device plugged into a 15 amp circuit must not draw more than 12 amps continuous. When you get into the larger UPSes, they might want to charge really fast, but charging at a high rate and carrying the rated load will exceed 12 amps. So depending on the rating of the unit, and the recommended input circuit, some models will definitely charge slow. 16 hours is not too fast for charging. If the UPS can't carry the load for ten hours, then the discharge rate is WAY TOO FAST. Most UPSes are designed to carry the load for about 15 minutes, so if you aren't killing the battery charging, you're killing it discharging. 73 -- Lynn On 9/1/2017 10:32 AM, Phil Kane wrote: >> Second, a local computer guru, AE6KS, has observed that most UPS mfrs charge batteries at too fast a rate for good battery life. > Both spec sheets show a recharge time of 16 hours.

IMO, power amps are totally out of place on FD, which I've always seen as a "barefoot" or QRP event. We do county expeditions for QSO parties like 7QP and CQP, and run two or three stations, each consisting of a K3, KPA500, KAT500, and P3/SVGA. Each station is powered by a Honda 2000i running in Econmode. They make some RF noise, which must be filtered with a good multi-turn ferrite choke. Follow the guidelines for chokes on RG8-size cable (k9yc.com/RFI-Ham.pdf), and place the choke right at the generator. Commercial line filters do NOT work. My neighbor W6GJB converted his 2000i to propane, and loves it. Mine is still burning petrol. 73, Jim K9YC On 9/1/2017 10:37 AM, Michael Chowning wrote: > Being there is no better place to get advice than this reflector, I am seeking your recommendation.

Little worried after I read this review: http://ve3vn.blogspot.se/2015/02/kx3-review-by-qrp-dxer-and-contester.html Is any chance for Elecraft to make (KIT UPDATE) for XV144 to use IF on 14MHz, the most transceivers has much better characteristic on 14MHz then on 28MHz. One can choose if they want to make XV144 with 28 or 14MHz IF, depending on use (CW, SSB, FM). 73' Samir, sm7vzx ------------------------------ Message: 25 Date: Fri, 1 Sep 2017 13:13:07 -0700 From: Mark Goldberg <[hidden email]> To: Michael Chowning <[hidden email]> Cc: Elecraft Reflector <[hidden email]> Subject: Re: [Elecraft] Portable Power for digital and Phone operation Message-ID: <CAKn+a3t=qvqA36nHc6EY6D1f3=txBOLXxJY_q_t=[hidden email]> Content-Type: text/plain; charset="UTF-8" On Fri, Sep 1, 2017 at 10:37 AM, Michael Chowning <[hidden email]> wrote: > Being there is no better place to get advice than this reflector, I am > seeking your recommendation.

The inverter generators are quiet though. I have been threatened that my RV generator will suffer from "Lead Poisoning" if it is run in the woods.

A description with specific models may be found on: https://sites.google.com/site/marksrvmods/ The RV has a large inverter for 115V. I previously used a large inverter standalone. Both are Xantrex, a good brand. They make some RF hash, but they are tamable with Ferrite cores. Some inverters are very noisy. 200W of solar panels and two 75 Amp Hour batteries will run a 100W ham station for field day late into the night. I have 4 batteries and 400W of solar panels to run the RV too. I am really keen on the flexible solar panels I use. They are very light and efficient. They have gotten lots of attention whenever I set them out. They may not be the best for a permanent installation, but for quick setup and teardown they are ideal. Note that MPPT solar charge controllers are the most efficient but usually make lots of RF hash. I use a Morningstar PWM controller that has a bang bang option, that will either be on or off, no RF hash from switching. It does reduce the actual output of the 400W panels to 300W though. Lipo batteries do not produce the right voltage for radios. 4 Cells is too much, 3 cells is too little. LiFePO4 batteries do and they are safer. A 4 cell pack runs from about 14.4 V down to 12 V at 90% discharge, which is ideal for remote operation. They still take special charging, sometimes built in to the batteries, but they are very expensive. I have a 20 Amp Hour from batteryspace,com that I use for long QRP, and I have a separate special charger. They also have ones with built in charging / balancing circuits, but they cost more. I have two small 4s1p LiFePO4 packs from buddyrc.com for remote QRP, but they don't seem to sell them any more. bioennopower.com has lots of options with built in charging circuits that make it a little easier and they get good reviews. I could not afford to have the big boys be LiFePO4 though and have not bought from them. A few hundred Amp Hours of LiFePO4 will be in the thousands of dollars. For all these batteries, it is a good idea to monitor them and stop using them when they get down to about 12V. LifePO4 especially can be permanently damaged if discharged too low. Good luck in whatever you choose. As you can see, there are many options with no "best" option for all circumstances. 73, Mark W7MLG ------------------------------ Message: 26 Date: Fri, 1 Sep 2017 13:31:00 -0700 From: Wayne Burdick <[hidden email]> To: Elecraft Reflector <[hidden email]> Cc: "[hidden email]" <[hidden email]> Subject: [Elecraft] Update on KXPD2 and KXPD3 paddles Message-ID: <[hidden email]> Content-Type: text/plain; charset=utf-8 I have to apologize for stating that there were mod kits available for the KXPD2 and KXPD3 that reflect improvements we?ve made over time. Turns out that we only upgrade existing units at the factory, so we can do complete testing before returning them. For paddles under warranty that aren?t up to the current configuration, we?ll add the upgrades on request, at no charge.

Re: Bluetooth audio adapter for K3
|
|
This idea of putting headphones and mic on Bluetooth has interested me for some time. Looking at the page on amazon, the 366-T device looks to be a transmitter only. That would be fine. You could hook it to the speaker or headphone output of the radio and buy a pair of Bluetooth headphones and listen just fine. In order to use your mic (as with an headset/mic arrangement), you would need a transmitter on your headset and another receiver on the radio, plugged into the mic jack. To use it, you would need to put the radio on VOX.
This brings visions of after market boxes strung all over the desk and one hung on your headset. I don’t know what the RF from the headset Tx would do to you. Do these things transmit continuously? I would be more comfortable with the idea if they only transmitted when you were talking on the radio. I am not up on all the latest gadgetry. Maybe someone can educate me. 73, Dave, K4TO ______________________________________________________________ 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] |

Is there a noticeable time delay when using Bluetooth? If so, it might be a problem for monitoring CW sending (or voice, for that matter).

Re: Bluetooth audio adapter for K3

No definitive answer here for this one, but I have seen that the delays
CAN be largely minimized under the latest BT4(+) specs.... down to 20ms or so theoretically(?).... Some of the older standards are 200ms+... 1/5 of a second could definitely be noticeable. I suspect it depends largely on quality of implementation in hardware/firmware/software... just like anything else. Disappointed that my admittedly limited searching thusfar has not revealed a single-box solution for what I envision is the "the" solution.... ONE box with a breakout cable allowing one to plug the BT xceiver into the back of a K3s at BOTH the headphone and mic jacks and accommodate a wireless BT headset and/or earbuds+mic like the Jaybird Bluebuds or X2 or X3 updates. I LOVE my Jaybirds and they'd be an excellent field option... Heck, I'd use them for headphones here in the shack even if I didn't need the additional isolation of over-the-ear cups. I'd use them for SSB/FM... Not sure about CW.... I'm just beginning to learn code.... BUT the thought of using my Jaybirds with a KX2 in a mountain biking or backpacking setting.... interests me. 73, ______________________ Clay Autery, KY5G On 9/2/2017 12:13 AM, Vic Rosenthal wrote: > Is there a noticeable time delay when using Bluetooth?
