Re: [Elecraft] Using dynamic mic on KX-3?
Kevin, I have not looked into the DX Engineering adapter to see how it is wired. You should get that information from DXE. What is apparently conflicting advice comes from the fact that all Heil ProSets are not equal and not all are supplied with an adapter. There are 2 basic types, one (like the Elecraft ProSet-K2 and the Heil ProSet-iC) use electret elements which need bias like your MH3. Others use a dynamic element and should not have bias applied. With that being said, take a look at the microphone plug on your ProSet - is it a mono plug (most are), and then look at the KX3 microphone jack pinout in the KX3 manual. When using an adapter such as the one from DXE, you have to look at the wiring for the adapter as well. Note that the KX3 microphone jack is a 4 circuit jack. The tip is AF, and the Sleeve is the shield (AF return). But the Ring1 and Ring2 will be shorted to the shield (Ground) by a mono plug. To prevent the KX3 from going into transmit when you insert a mono plug, you will have to turn MIC BTN to OFF. If you have an adapter, you may be able to leave MIC BTN set to PTT. Furthmore IF your microphone has a stereo (3 conductor) plug, then you can leave MIC BTN set to PTT if your microphone cable has an input for a PTT switch. What I am saying is that you have to compare the wiring of the mic plug on the Heil mic with the wiring of the KX3 mic jack. Since you are using the adapter from DXE, they should be able to provide the best information to you. 73, Don W3FPR On 11/9/2019 4:13 PM, Kevin Zembower via Elecraft wrote: Hello, new subscriber here.

The manual is a great start, but I collected some other ideas from this list and wrote a blog article. For example, you can use the DVR to listen to the settings. That allows you to hear your voice as other operators will hear it, without bone conduction. 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) __ 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] Using dynamic mic on KX-3?
No, not all Heil prosets use a condenser mike. Only the ones made for Icom rigs. If you bought yours from Elecraft that is probably what you have. Both of mine are not and have a dynamic elements. You can safely experiment with your KX3 by turning the power down to 0.0, at that stting on power out is generated and you can safely set the mic gain and compression and if you listen with headphones and turn the monitor level up you can hear what you will sound like on the air. Set the mic gain and compression as the manual says.

Dang.

Re: [Elecraft] Using dynamic mic on KX-3?
The Elecraft Heil Proset uses an electret mic element, so it needs bias. Yours uses a dynamic element, so it does not need bias. Your adapter from DX Engineering brings out the PTT contacts separately, so you should leave MIC BTN to PTT. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Nov 9, 2019, at 3:13 PM, Kevin Zembower via Elecraft > wrote: > > Hello, new subscriber here.

[Elecraft] Using dynamic mic on KX-3?
Hello, new subscriber here. Thanks for setting up this list. I'm trying to connect a Heil Pro Set Elite headphones and mic to a KX-3. I'm confused by what I'm thinking is conflicting advice. The Heil mic has a dynamic element, while the KX-3 is normally used with the MH-3 mic with an electret element requiring bias voltage. I'm using the HLN-AD-1-KX3 adapter from DXEngineering to connect them. With regard to RTFM: I found the section on page 38 regarding MIC BIAS and MIC BTN. I understand that I should set MIC BIAS to OFF for the Heil headset. I think I should also set the MIC BTN to PTT, because I have a foot pedal connected to the adapter. However, I'm confused by the flyer at https://ftp.elecraft.com/KX3/Manuals%20Downloads/E740174%20Proset%20for%20the%20KX3%20Rev%20A.pdf which seems to indicate that MIC BIAS should be ON, and MIC BTN OFF to disable all PTT switches. This indicates that the transmitter should be triggered only by VOX or the XMIT front panel switch. And, also confusing, I found the email thread at http://elecraft.365791.n2.nabble.com/Microphone-Setup-tp7609912.html which is for the K3. I wasn't sure if this advice for the K3 could also be applied to the KX-3. In particular, the note at http://elecraft.365791.n2.nabble.com/Microphone-Setup-tp7609912p7609921.html uses a MIC SEL menu option, which doesn't seem to be available on the KX-3. It does have lots of detailed information about settings for TX EQ which I'd like to use if applicable. I only have the opportunity to use the KX-3 at our club shack, about once a week, so I can't just turn to it and experiment. I'm also worried about causing permanent damage to either the radio or the headset by just trying things out. Any advice to clear up my confusion? Thanks for any help and guidance. -Kevin KC3KZ __ 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
