Re: QCX buzzing sound on key down


 

Thanks. It does it with a known good power supply into a dummy load sometimes. Sometimes it works for a few minutes. It’s in a die cast box with a 0.1 uF across the power connector and the power cable loops through a large ferrite. The antenna jack is fed with RG 174. It did work before. I will look some more when I get time.
