¿ªÔÆÌåÓýEvan Really appreciate the help. As soon as I read your email, thought why didn't I think of that. Had to take qmx all apart set brightness and it works fine. I am amazed felt sure it would not work. Have not tried transmit yet. It is a difficult kit for old guy with big fingers but so far good.? Thank you 73 Emory WM3M? -------- Original message -------- From: Evan Hand <elhandjr@...> Date: 9/5/23 11:54 AM (GMT-05:00) Subject: Re: [QRPLabs] QMX blank screen after initial load Hi Emory, Have you tried adjusting the contrast potentiometer???Start with it almost fully counterclockwise. 73Evan AC9TU |
