G'day everyone, Some of you may remember a thread I created a few weeks ago about the stiffness of the PTT button in my brand new MH2 microphone. (That I received with my brand new K3 #4257)
Now, I don't know if mine was a one off, but it had gotten to the stage that I needed to nearly crush the microphone in my hand just to get the PTT button to stay in TX mode. (And even then it dropped out with ANY sort of reduction in pressure.) Last night is was so bad that I took drastic action, I dismantled the microphone for inspection and then to perform surgery to relieve it of the rubber (neoprene) gasket from around the PTT button. The result? I now have a usable microphone again and we wont have to see or hear Samuel Morse rolling over in his grave due to my attempted usage of his code to communicate. :) It appears that during manufacture, the neoprene gasket had moved from its intended place whilst the glue had not yet set and as a result, the PTT button could not be sufficiently depressed to make reliable contact in the PTT switch. The surgery was successful and I now have a properly functioning MH2 microphone. The transmitted audio however was (and remains) perfect. Posted in the interest of maintaining the information flow.
