The "TUNE" tones from both applications (FLDIGI & WSJT-X) looks like a single frequency and is a pretty decent sine wave on the scope, although "pretty decent" is hard to quantify. It's more like the 500 Hz and its harmonics are beating with some process within the K3. The "pulsing " isn't

Is it possible that a beat note between tones (and their harmonics) is what’s modulating the ALC reading? If so, moving the tone slightly off the standard pitch may be an acceptable workaround. Wayne N6KR > On Aug 4, 2017, at 1:42 PM, Wes Stewart wrote: > > Good find

Hi Jim, I recently purchased my KX3 and intend on doing a lot of digital modes. I looked into 3rd party heatsinks, but was notified that Elecraft uses a new improved heatsink that wraps around the bottom of the KX3. So my question to you is, do you have the newer KX3 Elecraft heatsink or

Of all of the aftermarket KX3 heatsinks, the VE7FMN has the most surface area and mass- read that, it will be the coolest albiet heaviest heatsink you can add to the rig. I have one on mine, run RTTY and PSK31 a lot and never notice much in the way of heat at all with the heatsink. Look at

A blast from the past, it's been 17 years since I was involved with this stuff. In E1 PCM multi channel voice transmission systems the standard test tone was 1024Hz so as not to interact with the 8kHz sampling rate. This is not a fault but a fact of life. Maybe the designers would care to

I did a spot sweep in 100 Hz steps from 1000 Hz to 2000 Hz using TUNE function on WSJT-X. I observed, depending on frequency of the tone, the value of ALC indicated does change. This to me indicates the uniformity of the filter does show some ripple across the top. This is normal in my

Glenn, That method will give you a bad indication of the power output. Elecraft transceivers use a closed loop power control system - as found in some commercial transceivers, but as far as I know, not in other amateur transceivers. The result is that an Elecraft transceiver (K3, K3S, KX3,

Re: [Elecraft] K3: Odd ALC behavior

This is right for most ham transmitters, but wrong for Elecraft. Elecraft transmitters have a closed-loop power control that will try to keep the power at the set level (50 W) regardless of the audio input. 1. Set output power to 0 W and/or use a dummy load. 2. Set WSJT-X to “Tune”, where it
