Re: [Elecraft] headphone impedance

The headphones I have used for over a decade are 600-ohm high-end stereo high-fidelity phones. I obtain “comfortable” audio with my audio gain control set at about 9 o’clock. I am 99% CW, and they are my preferred-by-far headphones for both the K3 and the K3S, although I use something else

What am I missing? I use 600-ohm stereo headphones plugged directly into the front panel jack of my K3S. I run the Audio Gain control at 9 o’clock — roughly a 25% rotation toward full volume. I have more than enough audio for my elderly ears, and when I pull the headphone plug out of the

Re: [Elecraft] Internal SWR Readings

Rick, I believe you're confusing SWR and impedance. If a transmission line is lossless, the SWR will be the same along the entire length of the line. If a transmission line is lossy, the SWR will get progressively lower as you move closer to the transmitter. In an extreme case (such as 1000

One thing I haven't seen mentioned in this discussion is the sending speed at which the benefits of QSK disappear in the K3. Speed in words per minute (wpm) is very roughly equal to the number of dashes in a 5-second interval. Thus, at 25 wpm, there are 25 dashes in 5 seconds, or 5 dashes per
