There was no smoke. But the smell was all over the Shack. I was very scared and immediately turned everything off. I opened my Power Amplifier R-140 to explore its insides and to show to a specialist online. Fortunately, Ham Radio works also by low power and even QRP, especially when the good antenna and the active Sun help! ;-) -- If you find my activities in promotion Ham Radio useful, entertaining or inspiring, consider joining : ►Patreon: https://www.patreon.com/YLRaisa My other social media with Ham content: https://www.facebook.com/YLRaisa https://www.instagram.com/ylraisa/ 73&88 and see you On the Air!
