Re: [Elecraft] K4 and Yamaha CM-500 Mic?
Pete, I'm using a CM500 that is a year or so old. It replaced one that finally fell apart and I was tired of gluing it back together. When I replaced the headset, I did not need to make any adjustments! I went from a K3 to a K4 with the Yamaha headset plugged into the rear connectors. My Mic gain on the K4 is set at 12. TX rear mic configuration is Bias ON Preamp OFF. 73 George AI4VZ On Mon, Jul 31, 2023 at 9:32 AM Pete Smith N4ZR wrote: > My CM-500 is about 4 years old, and shedding ear-pads, but it works fine > with my K3. > > 73, Pete N4ZR > > On 7/31/2023 6:52 AM, Alan Bloom wrote: > > I had never used my CM-500 on a K3 so I can't do that comparison.

Re: [Elecraft] K4 and Yamaha CM-500 Mic?
My CM-500 is about 4 years old, and shedding ear-pads, but it works fine with my K3. 73, Pete N4ZR On 7/31/2023 6:52 AM, Alan Bloom wrote: I had never used my CM-500 on a K3 so I can't do that comparison. But on the K4 I had to turn on the internal mic preamp and set the mic gain all the way to maximum. That seemed to give about the correct level - I could talk at normal loudness to get 5 on the ALC. I also use the CM-500 on my laptop to record a radio show. I had to turn up the gain close to max on the computer as well. I think late-production CM-500s just tend to have low microphone sensitivity.

Re: [Elecraft] K4 and Yamaha CM-500 Mic?
I had never used my CM-500 on a K3 so I can't do that comparison. But on the K4 I had to turn on the internal mic preamp and set the mic gain all the way to maximum. That seemed to give about the correct level - I could talk at normal loudness to get 5 on the ALC. I also use the CM-500 on my laptop to record a radio show. I had to turn up the gain close to max on the computer as well. I think late-production CM-500s just tend to have low microphone sensitivity.

Re: [Elecraft] K4 and Yamaha CM-500 Mic?
Actually, I had (have) this very same problem and brought it up on here quite some time ago. CM-500, mic and phones plugged into proper jacks on rear, preamp on, bias on, mic gain at max, mic right at my lips, and I still have to talk very loudly to get any response out of the ALC meter. I got another CM-500 and swapped it in, and it was better…I didn’t have to talk as loud, but still way louder than I’d like or should have to. I never did puzzle out a solution for this. So if I need or want to get on SSB and can’t talk loud (say like if the XYL is trying to sleep in the next room), I put another mic on the front connector and have no problems getting plenty of response out of that, even if talking in a hushed voice. Oscar, if you find a solution to this, please be sure to post it on here…I’d like for this work…failing that I might try someday to find a different headset/mic combo... 73, Dave - N5DCH > On Jul 30, 2023, at 6:17 PM, Mike Dodd wrote: > > On 7/30/2023 7:40 PM, Oscar Staudt wrote: >> When I got my K4D a month ago, I unplugged my Yamaha CM-500 mic and >> headphones from my K3, and plugged them into the back of my K4.

Re: [Elecraft] K4 and Yamaha CM-500 Mic?
This may sound like a silly question, but are you sure you have the plugs in the right way round? i.e. Not swapped over. AFAIK this problem has not been reported on the K4 reflector and I know other folks are using them. 73, Alan - G4GNX South Coast UK Elecraft K4D / KPA500 / KAT500 / IC-9700 > On 31 Jul 2023, at 00:40, Oscar Staudt wrote: > > When I got my K4D a month ago, I unplugged my Yamaha CM-500 mic and > headphones from my K3, and plugged them into the back of my K4.
