That is a GMRS radio and would need to purchase a license to operate. Personally, I would use FRS (family radio service) which no license is required if you’re looking for something to communicate while traveling from your vehicle to another close by in your group or studying up on amateur (ham)...
Finally got to put the 4 wheel drive to good use this afternoon leaving from a small lake. Mud was slicker than snot and crawl control did nothing but spin. Put it in 4L with lockers engaged and pulled right out!
Make sure you’re in neutral when changing to 4L. Also, if it is still blinking, turn back to 4H then go back into gear and roll forward or backward a ft or 2 then stop and go into neutral and try 4L again.
Very easy and cheap.... go to the store and grab some hydrogen peroxide and a spray bottle. Mist it all over and let it set for about 5 mins. You will actually see the mold bubble away like you would pour it on a cut or scrape on your skin. Then just take a towel and wipe it off.
