Most of you know my 5555n2 has issues, but today i took the time to document my quick and dirty fix for anybody that might have the skipping or dead encoder issue. I chose this method because i don't use the stock mic any longer, and the stock mic was getting worn out and liked to jump frequencies while keyed up.
Step 1: Desolder or clip the resistors that control up/down from the stock mic. The mic will still work fine without them, but this will disable the up/down buttons.
Step 2: Drill some holes in the case somewhere and mount 2 momentary switches. Solder the mics resistors to 1 leg of each switch. Jumper the other 2 legs together and ground them to chassis ground. Now attach a wire to each resistor and join the 2 wires together, then attach another longer wire to the 2 resistor wires.
Step 3: Attach that wire to the top right most pin on the backside of the mic connector. (looking at it with the bottom cover off)
That’s it. Now you can switch channels / frequencies with your new up/down buttons on the radio.

Power on issues Q5N2
The Q5N2 I have had in my mobile for the past 2 1/2 years has developed an issue. Basically, sometimes it will come on when I turn it on and other times I have to turn it on and off many times before it will come on. Once it’s on, it works great. I have it hooked up to my base now. I’ve tried...
