Elecrafters, I have been monitoring WG2XIQ on 474.2 KHZ WSPR mode (With homebrew transverter, 7 mhz IF freq ) and noticed A ticking sound and could see it on the P3 panadaptor . It turn out that the ticking sound is the K3 clock. That’s not a big deal, However I would like to know if There is a way to turn off the clock. 73 Ken K5DNL
