radio noise
I'm getting a high freq. noise when I press the PTT with the
headphones and mic plugged in. With the mic unplugged it 's ok. With a handheld mic it's ok. Tried a different headphone, still noisy. I grab the mic wire and the noise goes away. Continuity cks ok in mic wire. What am I missing? Wires are shielded. Ed at wits end
