I like 1/4 inch plugs too, but most rigs nowadays have 3.5mm jacks! You can use an adapter, but that forfeits the purpose.

Re: [Elecraft] CM500 headset on K3S and KX3?
I normally use a CM500. OK, the RS60CF is a Radio Sport head set. :-) I used one of their headsets during our club's CQP county expedition. I liked the isolation from ambient room noise. Yes, it squeezes your head, but I could wear it for several hours at a time without feeling I was getting close to the end of my tolerence. I didn't use VOX at home in CA because my radio was set up in the family room with 20+ feet of space between the backs of the equipment and the front door. (Nice for moving wires.) My wife frequently would walk up to the radio and ask a question and I didn't want the answer going out on the air. :-) I did use VOX when I did a multi-op WPX contest at K9YC's QTH. In that isolated environment it was more convenient than my footswitch at home. Doing the contest was also a whole lot of fun, and watching the other ops was a excellent learning experience. What I'll end up doing here in NH is still up in the air. 73 Bill AE6JV On 5/6/20 at 11:39 PM, j...@audiosystemsgroup.com (Jim Brown) wrote: On 2020-05-06 1:16 PM, Grant Youngman wrote: Replaced them eventually with an RS60CF, and never looked back.

Re: [Elecraft] CM500 headset on K3S and KX3?
A couple years ago I bought the CM500 based on al the nice comments by others on this list. They failed me terribly; set up howling like a banshee minute I put them on (over my hearing aids) and not even connected to the radio. My hearing so poor that the amount of gain in my hearing aids fed back inside the acoustics of the ear-piece. No amount of fiddling with the headset stopped the feedback, so went back to wearing my Sony MDR-V600 stereo headset (which work well with my hearing aids). One if you bought the new CM500 from me for a nice discount, so I didn't loose out completely. I got a lot of advice back then which did not help/fix the problem (not wearing the hearing aids and turning up radio volume was one). In stead, I found a boom mic that attached to my Sony headset via an earth magnet "thingy" and that got FB audio reports. The mic has a foam wind-blast reducer and selectable omni or cardiod pattern pick up. Haven't really used the combo as I normally use my Heil desk mic in the shack. The boom mic was obtained for operating portable outdoors. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubus...@gmail.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

That's a characteristic of nearly all DIRECTIONAL mics -- those that On provide a single rear opening the capsule to cancel sound from the rear. Variable-D mics, virtually all of which today are made by Electro-Voice, have multiple openings along the "handle" of the mic body to provide the cancellation, and they have very little of that bass build-up. The earliest made by EV was the model 666, called "the Buchanan Hammer" because EV was in Buchanan, MI, and Lou Burroughs, who along with Al Kahn founded EV in the '30s, demonstrated the ruggedness of the new 666 to broadcast conventions by driving nails with it. When Lou wanted to retire, they sold the company to Gulton Industries. Al took his share and started Ten Tec, across the street from their mic and speaker factory in Sevierville, TN. Al was K4FW. I worked him once, on CW, using one of his radios. I was mobile from a campground in AR. Shure and AKG both made variable-D mics for several decades, but I don't think they still do. Modern variable-D mics are the EV RE10, RE11, RE15, RE16, RE18, and RE20. Last I looked, only the RE16 and RE20 were still in production, but there may be new models since I was active in the biz. The RE20 is quite popular as an announce mic. https://www.electrovoice.com/product.php?id=91 I know of no variable-D electret mics. 5/6/2020 11:39 AM, Walter Underwood wrote: > If I was going to upgrade my headset, I’d start with headsets used by sports broadcasters and ENG teams.

Re: [Elecraft] CM500 headset on K3S and KX3?
I have used the CM500 for many years. I have replaced the ear muffs with Koss's version. However, like Grant, I bought a RS60CF and have not looked back. Unlike Joe, I find them very comfortable, even after many hours in a contest. They cut out extraneous noise very well. The K3 TX equalizer provides excellent audio response. I use a pair of CM500's for portable work. So far, I've not had to use the spare set in spite of a lot of use and abuse. When we do Field Day for real again, I will likely use the RS60CF set to cut down on the inevitable background chatter the CM500 doesn't. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] CM500 headset on K3S and KX3?
History is more than a little ambiguous. Wikipedia ascribes the "first high-powered" Talk Box to Bob Heil [K9EID] for Joe Walsh, [WB6ACU] which was a 250 watt amp + hi-pass filter. However, Walsh credits an EE and steel guitarist [Bill West] with inventing it. Peter Townshend claims to have invented a version of the Talk Box during a Who tour in 1976. However, Bob Heil sold the manufacturing rights to Dunlop Mfr. building them to Heil's 1973 design standards. Peter Frampton says he first heard a Talk Box in 1970, and that Bob Heil gave him a custom built one as a Christmas present in 1974. He became proficient at it and is now often associated with it. It appears that every musical performer since then has used a Talk Box and at least a few assert invention. I use a Heil ProSet IC however I'm rarely on SSB. When I have been on, I often get unsolicited "great audio" comments, no doubt because of my sonorous broadcast voice as much as the proset. [:=) I use a CM-500 when operating W7RN remotely but I've never done phone remote. I find the ProSet to be a little easier on the ears with prolonged use than the CM-500, but both work well for me. As has been mentioned, a lot depends on how you place the mic and how you tailor the TX response and compression. I guess all microphones tend to accentuate the bass as you get closer and closer, exactly the opposite of what you want for communications. Electrets seem to be fairly immune to this, the old classic RCA 44-BX was notorious for the effect. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On Wed, May 6, 2020, 13:51 wrote: Interesting that Heil is not represented commercially.

Re: [Elecraft] CM500 headset on K3S and KX3?
If you can find them, "velour" pads are GREAT. Very comfortable, Softer and NO flaking. I replaced the pads on my Sony MDR-7506's with them. I especially like these Sony's since they have excellent high frequency response (better than the CM500's) which is perfect for my high freq hearing loss. Not sure if they'll fit, but somebody out there must make velour pads for the CM500's. 73, Charlie k3ICH -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Walter Underwood Sent: Wednesday, May 06, 2020 12:53 PM To: Elecraft Mailing List Subject: Re: [Elecraft] CM500 headset on K3S and KX3?

Interesting that Heil is not represented commercially. I believe that Bob Heil invented the talk box that Peter Frampton made famous.

Re: [Elecraft] CM500 headset on K3S and KX3?
Probably like Baufong radios, rip-offs of someone else's product. No, I've never heard of it. A story. A colleague in pro audio, excellent engineer, designer of sound systems in the US Senate, House, and White House, wanted to do a good deed for rock and roll churches who used a lot of mics. He imported mics from a company in China. Samples were great, so he placed an order. Production quality was VERY different. Like Baufong, we're talking $40-$60 for mics competing with EU mics that sell for $1,000 - $1,500. Quality companies like Shure and Switchcraft have long huge problems with counterfeits of their products, and counterfeit mechanical and structural parts have long been a problem for manufacturers. I remember reading about that in the aircraft industry more than a decade ago. 73, Jim K9YC On 5/6/2020 5:32 AM, Lyn Norstad wrote: There is a (presumably Chinese) mic known as the BM800 which is marketed under several different names.

At this price point, I’d expect electrets to be the best performers. If I was going to upgrade my headset, I’d start with headsets used by sports broadcasters and ENG teams.

Re: [Elecraft] CM500 headset on K3S and KX3?
I bought a pair of CM500’s when they became all the rage a few years ago. Never liked them. The mic sounds ok, but they’re just too loosely-goosey a fit and I find them fiddly and not very stable on the head. I used them for a while and tossed them into the pile of too much stuff I bought and don’t use. Replaced them eventually with an RS60CF, and never looked back. Cable sets for both the KX3 and K3(K4). And yes — I know there are a lot of people who don’t like those, either. But I do. All a matter of personal choice, I guess :-) David Clark makes a small and inexpensive soft-case that fits them perfectly, too.

Re: [Elecraft] CM500 headset on K3S and KX3?
My CM500’s earpads are flaking pretty badly, leaving little back bits around the home office/shack. They still work fine. I purchased them in December 2012. I see that the same order has Eneloop XX batteries and a LowePro Edit 140 case, so that was all ordered to go with my brand-new KX3.

Re: [Elecraft] CM500 headset on K3S and KX3?
Frank, Although the K3S rear jack is marked mono, it is actually a stereo jack, but the ring connects to nothing - so no harm. On the KX3, look in the manual for the MIC jack connections. It should tell you why you need to be aware of the situation that the CM500 plug can present. Walt Underwood K6WRU has presented a link to an adapter that will allow you to plug the CM500 mic plug into a jack leaving the other jack available for us as PTT. Use of that adapter does not require you to set MIC BTN to off. Be careful, not just any adapter will do - some are simple splitters that put both the tip and ring on both jacks. 73, Don W3FPR On 5/5/2020 10:43 PM, Frank O'Donnell wrote: Thanks for the clear instructions from Don, and the helpful suggestions from everyone else.

Re: [Elecraft] CM500 headset on K3S and KX3?
Frank; The rear-panel mic input on the K3 and K3S is actually a stereo jack. The ring connector is not connected. Plug the CM-500’s mic plug in (as I do), and it will work just fine! Remember to enable bias on the rear panel Mic as W3FPR noted. The CM-500 is an excellent headset for use with the K3. You should get many years of excellent service form it. 73!

I adapters needed. CM500 plugs right into the rear Mic and Phone jack on K3(s). Also the KX3, just turn OFF Bias and Buttons. PTT is available on rear PTT RCA jack on K3(s) and Tip and Shield on KX3 Accessary jack ( a 3/32 TRS Jack next to the I/Q Jack). Use switch of your choice; an old J38 works real well here. Use the “shoring bar” for long conversations. Sent from my iPhone ...nr4c. bill > On May 5, 2020, at 7:33 PM, Frank O'Donnell wrote: > > Phone newbie here.

Re: [Elecraft] CM500 headset on K3S and KX3?
The ACC2 connector is a 2.5mm TRS connector, not 1/8” (3.5mm). PTT is either on the tip or ring, I don’t recall which off hand — check the manual.

Re: [Elecraft] CM500 headset on K3S and KX3?
Thanks for the clear instructions from Don, and the helpful suggestions from everyone else. Piecing it all together, will this basically work?: -- On the K3S, plug the CM500's mike and phone plugs into the respective jacks on the rig's rear panel. Wire a momentary-contact switch to an RCA plug inserted into the rig's PTT IN jack to serve as a manual PTT switch. -- On the KX3, plug the headset's mike and phone plugs into the respective jacks, and use a momentary-contact switch on a mono-style 1/8" plug in the ACC2 jack as a manual PTT switch. The only thing I'm concerned about is the issue of mono vs stereo plugs. For example, the CM500's mike plug has stereo-style contacts, whereas the mic in jack on the K3S is marked "mono." There aren't any issues there? On other points, if I were going all-in on becoming a regular phone operator I might look at other headsets such as the Heils. But what I'm looking at is being a bit player on a couple of nets very occasionally at most, so the CM500 seemed like a decent option. Re VOX vs PTT, I can understand the convenience of the former, but being an occasional throat-clearer I wouldn't want to become a distractions on those nets.

The harder way for the KX3 is to make an adapter (but it is not that hard) Be aware that, like most computer microphones, the tip and the ring of the plug are wired together - so if you make an adapter, you must use a stereo jack so the audio is not shorted to ground. If you make an adapter, you can include a connection for a PTT switch, but without that, you can put the KX3 into transmit with the XMIT button. 73, Don W3FPR On 5/5/2020 7:31 PM, Frank O'Donnell wrote: Phone newbie here.

Re: [Elecraft] CM500 headset on K3S and KX3?
The failures I have are the ear pads disintegrate. Someone said Koss pads could work but that hasn't been my experience. I've found some '500s at estate sales where I snap them up. Currently the law firm where my fiance is employed is working from home and she's using a set on her computer to "attend" on-line meetings. I guess I can add "IT Manager" to my resume, since I'm helping her with her connections. I second the use of VOX.

Re: [Elecraft] CM500 headset on K3S and KX3?
I bought this because my soldering skills are not what they once were. (Used to do MIL-spec, now I’m lucky to hit the joint with the iron. ). https://shop.technofix.uk/hand-ptt-switch-for-elecraft-kx3-2-5mm-jack Plugs into the ACC2 jack directly. Instructions are on the page. Works FB. It and my Yamaha are inseparable.

Re: [Elecraft] CM500 headset on K3S and KX3?
Frank For what its worth and everyones milage will vary, I had a brand new CM500 that I used for a week of hard operating while on a pretty island and the boom came loose after a couple of days. Since then I have reliably used the Elecraft sold Heil Proset at home and other pretty islands. Ironically I bought the CM500 as I didn't want my Heil abused in transit or when operating away from home. From memory no additional adapters are needed for use with the KX3 and I find it easier (but friends don’t) to use VOX.

Re: [Elecraft] CM500 headset on K3S and KX3?
For the KX3, an off-the-shelf stereo-to-mono splitter will separate the mic and PTT lines. It also separates the mic bias (clean) from the logic signal (not so clean). Details here: https://observer.wunderwood.org/2015/08/16/yamaha-cm500-headset-with-ptt-on-elecraft-kx3/ For transmit audio setup, I collected various bits of knowledge from the manual and this list into a single article. https://observer.wunderwood.org/2015/09/09/transmit-audio-and-compression-with-the-elecraft-kx3/ wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On May 5, 2020, at 4:31 PM, Frank O'Donnell wrote: > > Phone newbie here.
