Amateur radio videos: Extreme toroid winding, CW bandwidth, KB6NU on LICW
Need to wind some toroids?
While Iβm waiting for my QRPLabsβ QMX kit to arrive, I thought Iβd 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, βWhat is the approximate bandwidth required to transmit a CW signal?β The correct answer is 150 Hz. The question says βapproximateβ 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 donβt 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.
