Re: [Elecraft] Oddity in K3 with new synthesizer

When I get time I'll have to look at this. I have an old K3 with the original synthesizer and no TCXO and a new K3S with a TCXO. I also now have a GPSDO. After getting this, I checked the K3S and was not thrilled to see that the TCXO required a 20 Hz adjustment. Wes N7WS On 3/5/2016 6:43

Re: [Elecraft] ALC adjustment on K3S

I don't use JT modes, but on RTTY and PSK I've found a similar issue with my K3S. I've mentioned it here in the past more in reference to the built-in sound card super sensitivity affecting VOX setup. The best I've done is to go into the Windows Sound setup and reduce the output (speaker)

Re: [Elecraft] K3s Odd sound vibrations Edit - Hypothesis, Steps, Conclusion, and Request.

I don't think you're an idiot. I've reported a few defects to Elecraft over the last 8 years. Usually they get fixed and are sometimes folded into production. There are thousands of guys using K3s that include a fix that was developed using my radio as a prototype after I demonstrated it to

Re: [Elecraft] Balun Questions

Bob, It appears that you're of a mind that the winding (coax) is tightly wound around the core. That's not how some guys are doing it. It's just loosely looped through the core. See fig. 36 in Jim's paper. Wes On 2/7/2016 10:03 PM, Bob McGraw K4TAX wrote: I am speaking of the radius

Re: [Elecraft] Balun Questions

If you're driving a 50 ohm load, then the cable wound around the core is just an extension of the transmission line and has no impedance modifying effects. The significant parameter is the common mode (CM) impedance. G3TXQ discusses a way to measure it here:

I can second Jim's concern about have one's work usurped by another. I can recall Googling a topic and having a paper come up on some Canadian's website that appeared to be written by him but in fact was my ladderline paper. I emailed him and asked him nicely to remove it and simply link to

Re: [Elecraft] KAT500 tuning problem

After a good tune, I would use the KAT500 utility to examine and record the selected component values. When the failure occurs, before retuning I would look at them again and see if they are the same. Also after a good tune, I would run up and down the band to cycle the relays and see if

Re: [Elecraft] K3/K3S noise blanker performance greatly enhanced (at my QTH) -- need testers

Not to put too fine of a point on it but strictly speaking, that is incorrect. The characteristics of a pulse that can be blanked are: 1) its amplitude is sufficiently greater than the desired signal so it can be detected as undesired (noise) 2) its duration isn't so long that the "hole"
