This Does MORE Than Power Your Smoke Detector
A year ago I purchased and built a QCX Mini (40 Meter version) QRP CW transceiver from QRPLabs. My main reason for this purchase was the small nature of the radio. A subsequent added reason was its capacity to operate with 9 volts. Over the last year I have used this rig several times using a 9 volt / 200 mah battery. Most recently August 26th and 27th, 2023 during a Parks on the Air activation. On those two days the Terrestrial weather was extremely HOT with daytime high temperatures near 100 degrees Fahrenheit. My activations on those two days were at or near sunrise. Even at sunrise it was warm, humid and muggy with sunrise temperatures hovering in the low 80's. However, the Space weather was working in my favor with the SFI at 139, A index of 6, K index of 2, Sun Spot number of 70, and Solar Winds of 380. The noise of the HF bands was relatively quiet. My antenna for both days was my 40/20 Meter Linked End Fed Half Wave antenna I constructed from Tufteln. Joshua / N5FY has
