Note that I was not asking why I see the KPA500 or STANDBY message. I was trying to see if anyone experienced what I did where I see the message all the time. In case anyone else experiences a similar

I did some more playing around with this thing.  Under "Other devices" i double clicked on the 232 icon that was showing.  It did something and now it shows USB serial port.  However the KX3

Under other devices it shows a FT@#@R USB UART. Scanning for hardware changes is quick with nothing being returned as having been found. Same thing when i scan for hardware

Mic bias (8v) is sent on pin 6 not the audio line. That is Icom that shares audio/bias Sandor KG4FET GOD SAVE OUR NATION!

Ok I need to learn more about this KE7X dude! Thanks, Mike NJ2OM

Also most icoms require bias so if that mic is advertised for icoms that may be a clue. The heil website should tell you. 73 Mike R 7! Absolutely Awesome

Yes I just saw that myself. What it is a page from KE7X’s manual with a list of microphones and how to set them up. Let me give it another try. LOL Ed.. AB4IQ

Ed I don’t see an attachment. Thanks, Mike NJ2OM

Maybe the attachment will help Mike. Ed.. AB4IQ

Easy way.......start with the BIAS OFF. (a) If it works as expected then it is most likely dynamic. (b) If it doesn't work, then most likely it is Electrect and thus

That sounds really interesting Graham. Did you use this with what radio, a K3? What is your reason for selling it? I'm impressed with the documentation but not knowing much and

Hello Mike. If the headset has a 8-pin connector, make sure it is wired to match the mic pin out from the K3. If it does than turn ur Bias OFF in the K3 menu. Speak into the mic. If it modulates

I have no idea if this Heil headset has an electret or dynamic mic. Is there a way to determine that? I don’t want to take a chance of messing up the rig. Maybe it would show up when using the

You can go into configure and turn the mic bias on, or off.. Everett N4CY Sent from the all new Aol app for iOS

I think that Elecraft sends the bias voltage on the mic's audio line, so if a dynamic mic is used, then it will have voltage applied to it, which is NOT good for it! Some rigs have a separate bias

Electret mikes require bias. Dynamic mikes, regardless of brand, must not have bias on. 73 Bob, K4TAX On 2/3/2021 7:50 AM, Mike Kopacki wrote:

I have several mics wired for the K3 only one of which uses the bias voltage. As far as I can tell IF the mic isn't wired for the voltage pin and is dynamic having bias on doesn't matter. The one

Any mic. Headset is irrelevant...

The K3S manual says "Bias must be turned on for electret mics (e.g. MH2, MD2, Proset). It must be off for dynamic mics (e.g. Heil mics using HC4 or HC5 elements)." Does the Heil comment include Heil

When combined with a PC internal or external sound card and free software (PowerSDR, NaP3 etc), you can use this to create a Panadapter for your K3/S up to 192KHz wide. Full details on how it works
