I was thinking that as the "ALC" meter isn't really showing ALC, but audio level when below I believe 5 bars? - that the ALC isn't being modulated, rather what we may be seeing is an artefact caused by the way the peak level of the audio is detected by sampling the audio at a particular

I said earlier: "If I set the tone to 1500 Hz, the FT8 mid-band target, I'm presented with the cyclic ALC and some ~193 Hz, -50 dBc sidebands. " Ten KHz/div is too coarse to see these. Try again. Wes N7WS On 8/5/2017 1:01 PM, Brian Hunt wrote: Here are some spectrum photos from the tune

Re: [Elecraft] K3: Odd ALC behavior

Here are some spectrum photos from the tune signals of both FLDIGI and WSJT-X 1.8. All three are essentially identical showing some low level sideband noise +/- 30 kHz and down > 60dBc. There's no apparent difference in the spectra between pumping and non-pumping ALC, as Wes reported.

Except when the sound card is in the computer instead of the radio, "Line In" is receiving signal from the program via the sound card 'speaker' output, not the microphone. Moving the card into the radio doesn't change this. The only thing changed is it's too darned sensitive. Regards, Wes

Re: [Elecraft] K3: Odd ALC behavior

Wayne, There are no beat notes. These frequencies, at least from the FT8 program in Tune mode are single frequency. Based upon output RF spectrum measurements*, with for example 1010 Hz input and 4-5 bars of ALC, I see spurious or intermodulation sidebands, down -65 dBc. If I change nothing

Re: [Elecraft] K3: Odd ALC behavior

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

Re: [Elecraft] K3: Odd ALC behavior

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

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

Here's some followup: FLDIGI shows the "pumping" affect with carrier tones of 500, 1000, 1500, and 2000 Hz. WSJT-X 1.8 shows the "pumping" affect with carrier tones of 1000, 1500 and 2000 Hz (couldn't select 500 Hz). The affect is very narrow with frequency. 10 Hz either way and the output

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

Better yet, just turn on the MON function on the radio and listen to the tones. They must be perfectly clear and clean.And yes, I've found that over driving the sound card will do really funny things to the ALC and its display.Start low and work your way up. Remember there are 3

In RTTY are you using FSK or AFSK? I'm surprised that you find the SPEAKER level at 100% as necessary. Of course different sound card in computers behave differently. Also the Line In at 4 sounds awfully low. I'd think more toward mid way is better with better resolution in regard to

Steve, Those settings are too extreme - they need to be more mid-range. Set the K3 LINE IN gain to something mid-range (about 30), then reduce the soundcard and WSJT-X settings to about 50% and give it a try. Adjust the computer soundcard and WSJT-X settings to produce 4 bars on the ALC meter,

Dave, I have exactly the same problem. For me it does not occur with RTTY. That seems to be solid. JT65 and FT8 really show the problem. When the problem occurs I can often make a RTTY transmission and suddenly the ALC shows for FT8/JT65. I have multiple soundcards in my computer and in theory

Dave, Set the K3 LINE IN gain for a midrange value. It has more resolution there than at either a high or a low setting. Then adjust the soundcard to obtain about 4 bars on the ALC meter and "fine tune" that level with the LINE IN gain to get the 5th bar to flicker. Note that this is the NO
