Glad you like this method of? using resistor? attenuation? and get away from charging and discharging of capacitors when we power up circuits.? this method I have use last year on a commercial product I was working on to get rid of microphone mechanical switching noises. The 0.1uf? added to the gate gives it a slight delay and just in case RF pickup since we are using this in a transmitter. For a faster switching might try a smaller capacitor eg. 0.01uF.
??? i am busy lately on a new commercial project so I have to set aside the UBITX? hobby. Analogue? is more fun than digital but digital simplifies controls with more complexities .
