Re: [Elecraft] Yamaha CM500 Headset is a WINNER (and a BARGAIN), maybe
I picked up one of the CM500 headsets after hearing about them here on the reflector. I just tried to hook them up by plugging directly into the rear mic jack, and I'm having some difficulty getting the mic to work. I selected (of course) rear mic input, and what is happening is I'm getting very distorted audio when I listen in monitor mode. I tried both hi and low mic gain, with different mic gain, and compression settings. There appears to be no sweet spot. Any ideas? 73 Jeff kb2m -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Wes Stewart Sent: Monday, November 23, 2009 1:52 PM To: Elecraft List Subject: Re: [Elecraft] Yamaha CM500 Headset is a WINNER (and a BARGAIN) I second all of this.

Great reports, comfortable all weekend, good soundproofing. A real bargain at $40 -- thanks again for the group purchase, Josh (W6XU). After about 22 hours of use in SS-SSB, I'd like to reinforce John's comments on these headsets. I find the headset quite comfortable, the cans sound very good, and the mic produces GREAT audio. I bought three, and they are replacing the EV RE16 that I've used exclusively for contesting for the last five years! If you worked W6BX, K9YC, K6MM, AK6M, or W6XU, you were listening to the CM500. The mic in this headset is not a FLAT mic, but it's quite smooth and clean sounding, and the EQ is close to perfect for ham radio and contesting. It sounds MUCH MUCH MUCH better than most Heils I've heard (and at 1/3 the price). Because it's EQed for communications use and my existing voice messages were recorded with an RE16 (a very flat professional recording/broadcast mic), I had to re-record all of my SS messages. The only negative of this mic (and it's a minor one, because it's easy to work around it) is that it is a bit sensitive to breath pop and handling noise, so you need to roll off the low end AND keep it away from your mouth. I found myself alternating between two positions -- one below my mouth a few inches, and the other a few inches above and to the side, but out of the way of my nose (so that breathing didn't get into the mic). Both positions are quite comfortable, and both sound very good. I used the higher position for recording the messages. One VERY important caution -- the output from this mic is VERY high, and can easily overload the electronics that it is feeding if you don't take care with gain settings. To record, I ran straight into the sound card of my IBM T22 (eight year old Thinkpad) with the mic preamp OFF, the gain at minimum, and the mic about four inches away. Any closer caused the sound card to clip! I did NO eq while recording. When operating, I plugged the mic and headset into the rear panel connectors, turned on the bias (tap 2 on the keypad while in the mic select menu) and set mic gain to Low (tap 1 on the keypad in the mic select menu). I used max cut of the two lowest bands on the K3 to minimize the breath and handling noise. With other rigs, you may need to do that with a series cap. 73, Jim K9YC __ 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

Have you turned on the mic bias?

Yes I did read it Jim. I didn't think it was necessary to mention that I switched it on, I now see that I was wrong. As you(and more polite repliers) think that is the problem I will, when I have some time try to determine if the bias is actually present when switched on. By the way Jim, are you always this grouchy? You must of not did the Sweep like I did ;) 73 Jeff kb2m -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Brown Sent: Monday, November 23, 2009 3:36 PM To: Elecraft List Subject: Re: [Elecraft] Yamaha CM500 Headset is a WINNER (and a BARGAIN), maybe On Mon, 23 Nov 2009 14:55:43 -0500, Jeff KB2M wrote: I'm having some difficulty getting the mic to work.

Re: [Elecraft] Yamaha CM500 Headset is a WINNER (and a BARGAIN), maybe
I had some time this evening so I checked that the K3 was actually putting out the bias when switched on. It is, I then called the local Guitar center and talked to the sales person who told me no problem, if their defective I will be able to exchange them. It's great to be able to buy something's local, and they even matched the Sam Ash price. I will have the new set tomorrow... 73 Jeff kb2m -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jeff KB2M Sent: Monday, November 23, 2009 3:57 PM To: 'Jim Brown'; 'Elecraft List' Subject: Re: [Elecraft] Yamaha CM500 Headset is a WINNER (and a BARGAIN), maybe Yes I did read it Jim.

Two things set me off -- one is quotes of entire posts when only a few lines are necessary to convey context of the reply. The second is folks who say they like what I've written but then ask questions indicating that they haven't really read it carefully. I offered four specific pieces of info about how to make the mic work with the K3. I did that with both of my K3s, and several NCCC members did it with their radios. All work fine. BUT -- as I noted, the mic is VERY hot (high output) and can easily overload your computer or radio, so it's VERY important to back off the gains. If you don't, you'll hear LOTS of distortion. You must of not did the Sweep like I did ;) Congrats on the sweep. I ran a split site operation to maximize points for our club -- 10 hours at home, 11 hours at N3ZZ's great station. 913x79 mults there, 575x75 at home. I did something similar CW weekend, and made the sweep at home in 14 hours, but not at the second QTH. 73, Jim K9YC __ 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
