[Elecraft] K3 Popping noise in headphones??

I vaguely recall reading a post that at narrow CW bandwidths the RX EQ is turned off automatically. That can result in a pop as bandwidth is changed if RX EQ is not flat near the chosen sidetone pitch, with the severity of the pop depending on your RX EQ settings. This predated the new synth,

Re: [Elecraft] K3 Popping noise in headphones??

The selection of IIR versus FIR filtering for the narrowest bandwidths (50 Hz and 100 Hz) may also have some effect on this. In general, the K3 and K3S switch to a different filtering algorithm for these two bandwidths. The loading of coefficients and filter settling time -- and to some

Re: [Elecraft] K3 Popping noise in headphones??

I don't use any RXEQ and my pitch is usually between 400 and 450 Hz. Yes, 100->150 is "worse", although not particularly objectionable; a curiosity actually. But there are other pops too, 750->800 is about the same and there is also a dependence upon the shift. On 10/18/2015 11:16 AM, Joe

The clicks are there regardless of the level of the AF gain setting. The loudness of the clicks is affected by the AF gain setting, but they are still there. I'm using a Yamaha CM500 headset. It is the strongest when moving between the 0.10 and 0.15 bandwidth setting, but also occurs going

Re: [Elecraft] K3 Popping noise in headphones??

As a point of reference, my old K3 with the original synthesizer board pops when changing BW. It's most noticeable going from 150 Hz to 100 Hz and vice versa. This is with normal AF gain and CM500 in rear headphone jack. On 10/16/2015 6:01 PM, jim wrote: I just got my K3 back from Elecraft.

I can verify that I get the popping (more like a click) and it's loudest between 150 and 100 Hz transition. It doesn't bother me. My K3 is S/N 1326 and I have the new synth installed. Bert, N4CW __ Elecraft mailing list Home:

Hi Jim, I have an older K3 with new SYN boards. I also have the 500Hz and 200Hz filter. I just tested it on CW and I can hear a very faint pop when turning the bandwidth knob. As you noted, it seems to be present only at the narrow settings. I start to hear it when changing from 350 to 300 and

I just got my K3 back from Elecraft. They did the once over and installed the new SYN boards. I have noticed a "popping" noise in the headphones as I change the bandwidth control, but ONLY as I transition from 200 Hz, 150 Hz, 100 Hz and 50 Hz. I have only checked this in the CW mode.
