Need to wind some toroids?

While I’m waiting for my QRPLabs’ QMX kit to arrive, I thought I’d try to learn something about toroid winding. This video takes toroid winding to a whole new level.

W2AEW on CW bandwidth

Question T8A11, in the Technician Class question pool asks, β€œWhat is the approximate bandwidth required to transmit a CW signal?” The correct answer is 150 Hz. The question says β€œapproximate” because the bandwidth depends on the speed at which the Morse Code is being sent.

In this video, Alan, W2AEW, actually makes some measurements to determine the bandwidth of a CW signal.

KB6NU on LICW

A couple of weeks ago, Bob, K4LRC, Β asked me to speak to the LICW Portable Ops group about getting better at CW. I guess they ran out of qualified speakers. I don’t know if the group learned anything, but it was fun to speak to the group. TL;DR getting on the air and making contacts is the best way to improve your CW.
