The truck is stock. As soon as you put the truck in reverse static. Switch to park or neutral no static. Switch to drive static. It does not increase with engine speed like alternator noise.

Installed a Midland in my friends new F250. Sitting in the driveway engine running or not no problems. As soon as the selector is put in reverse or drive I get instant interference. We had to turn the squelch way up in order to get rid of static. I used the upfitter switch for power. I'm guessing some sensor in the truck is interfering with the radio. Do I need some sort of choke? Or maybe power directly form the battery?

You need to activate the repeater channels on your unit. The transmit and receive frequencies are already plugged in. Let's say the repeater you want to hit is on channel 20. Tune to 20 it should say rp for repeater. Next you need to set the code. If you look at the table, 141.3hz is on the CTCSS Code chart. 141.3 corresponds to code 22. So on channel 20 you need to program the CTCSS code to 22. I'm new to this also but this is my understanding.
