Hi Chris; I would stop using the radio immediately! Sounds like the main audio chip U1 on the DSP board is going out. When they fail, you can get a HI CUR warning because they are shorting out. They can heat to the point of destroying the DSP board (which we don't have anymore). Digikey

Hi I have a strange problem with my K3/100. The audio through the internal speaker is low, but comes up much stronger with any slight movement of the volume knob. Then it goes back down again, often accompanied by a brief HI-CUR warning. Also when AGC is turned off, audio is almost zero. But,

You can use the line in/out connectors in the back of the radio and a "sound card" for your computer. USB sound cards are available inexpensively from Amazon. I have one for my KX3 which I think cost about $5.00. You may need to install a pad to lower the signal level between the line out on

> Is there some adjustment I’m missing? Try adjusting the center frequency (shift) or decreasing the Low Cut (FL) and High Cut (FH) by similar amounts. In general, the important spectrum for speech is 400 - 2200 Hz while simply "dialing down" the width causes the Low Cut to raise too quickly.

[Elecraft] K3 Audio

I’ve found the audio with narrow filtering is much “clearer” to my ears (using a Heil headset) on my Kenwood TS480 than on my K3. I spoke with another person who owns both radios and he finds the Kenwood audio crisper, less “mushy.” My K3 is a great radio, but I’d sure like to hear better. Is

Re: [Elecraft] K3 - Audio Drops

While I never suffered from the "audio drop" issue after shutting down Log4OM, it seems that the new WSJT-X 1.7.0 produces the same effect when it is terminated. My K3 goes absolutely silent. Touching the WIDTH control brings audio back. WSJT-X is widely used, so hopefully there is a chance to

Re: [Elecraft] K3 audio quality

Hi Bill, One thing we learned many years ago in pro audio is that in general, it's a bad idea to use "boost" EQ, especially to boost a lot of bands, and to boost them a lot. The reason is "headroom" -- when you're boosting a lot, you're more likely to hit digital clip on audio peaks. I

Re: [Elecraft] K3 audio quality

I rest my case. I think if you blindfold someone and tell them their listening to a K3(s) they'd come back with the same "it sounds like %$@!" answer even if it was another manu's rig they were listening to. It's a self sustaining urban legend now. On 9/16/2016 2:18 PM, Greg wrote: When I

Re: [Elecraft] K3 audio quality

Hi Jim, ... It's all very simple physics. Look at the size of the loudspeaker. Its low frequency output is limited by its size as a fraction of a wavelength. The K3 and K3S are designed as compact, light weight radios. The speaker used is quite good for its size. If you want big bass, you
