This is a very good 2 meter radio.
After you own this radio for a while it will develope a crackling sound in the speaker on transmit. It can also be heard on your signal over the air.
Here is the fix:
(Warning! Do this at your own risk. This may void your Icom warranty.)
Remove the four screws that holds the cover on. You will see a bunch of 3mm screws that holds down the main board to the case. Loosen all the screws and then re-tighten them.
The noise will go away. If you want to get really fancy you can attach #4 star washers under each screw.
Also with the display facing you, there will be two holes on the left side of the circuit board. Place a #4 3/8 self tapping sheet metal screw in each hole. Not only will this make the noise go away, it will improve your quality of modulation. People will notice if you have been working them for a while.
