Sharing my antenna tuner

After a club.meeting some members asked for a demonstration of using an antenna tuner. Although there are a lot of YouTube videos and articles online I did not see an example like the one I was given as a young operator.


Loading an incandescent light bulb

Using a light bulb as a dummy load is a good way of seeing how tuning affects power. Fun as well. But note the bulb will still transmit so use your call sign and watch what you say.

Tuning an Antenna

Showing me tune the antenna tuner to get a good match, eventually. 

First I tuned the receiver to a noisy signal on the band, then I tried various tuner settings to find one where the noise/signal from the radio could be peaked, this became my starting point for tuning with a real transmission.
