Nah, don't squelch it, never felt the need. In the heat of combat I don't even notice. Maybe something to do with the hours I'm playing (GMT +1 based).
One day I took off from a carrier, nicely close to an undefended field (rare occasion). Flew around a bit, got into a dogfight with the lone guy/gal rising to meet the challenge, f*cked up as usual and had to chicken out low over the water to my CV. Suddenly a million check 6-es and a truckload of verbal abuse over my own countries channel. Without ever noticing the text buffer or paying much attention, a lone guy had managed to get the carrier close, level the town and was on the verge of capturing the field with a LVTA. He thought I was buzzing him for air cover, asked not to but I hardely noticed him in the heat of the dogfight. You can guess what happened, he got blasted and I took the full frustration of that. I HATE agression towards me in any shape or form but I can understand his sentiments. But nevertheless, it's only a game...
squeaking over vox can be annoying, I got a lot of abuse lately for 'stealing someone's kill'. Weeelll, the person involved was already chasing that Fw-190 when I WAS TAKING OFF and still hadn't got him when I got up to a nice speed and altitude to engage. I had him in seconds, even with the sucky cannons of my La-5. If you can do better shoot him first.
