    Always listen to the experts, they became experts by learning from their past mistakes, I bet Ray would wholeheartedly agree on that.

    Excellent. I’ve been involved in various forms of radio for many years but only decided to get my amateur licence during covid. Very well explained and I love your humour especially in the Amberley Museum video. All the best. M7SFV.

    Been a ham now 26 year I know all that stuff but I still like to see different equipment being used and we never know everything that's why the hobby is so amazing. I'm learning about tubes now I find them fascinating how 3 glass bottles give 200w out of my FT-102

    Thank you for another fantastic and practical video, Ray! Your explanation on the correct order of connecting the transceiver, SWR meter, and ATU is spot on, and explaining why we shouldn't run coax after a manual tuner clears up a lot of common mistakes. Appreciate you sharing your knowledge, especially during that heatwave! 73 de YO2CPS

    It is still a topic that causes some issues for those just starting out in the field. <br>You did a great job creating this video on the subject. It’s always worth reflecting on your words, Ray. <br>Keep up the good work! <br>Cheers! <br> <br>Macedo Pinto, <br>Portugal<br>73
