All you need to do is remove the solder with a solder sucker and then add a small drop onto con2, you can probably take a small screwdriver and move the diode a small bit, it really isn't that big of a job, I have done 3 radios now and they were all 5 minute jobs. If you can't solder then take it to a tech, or you can google how to don the mod, cb radio magazine has a write up and photos to guide you. But like I said if you aren't comfortable with the job take it to someone that can solder it for you. Also read the owners manual, it explains that the diode needs to stay bridged between con 1 pin 1 and con 3 pin 1. Just remove the small solder blob in between con 1 pins and add a small blob onto pin 2 for stealth mode or pin 3 for expanded mode. I would personally just use con 3 unless you have a ham license and are planning on using the stealth mode features. I put all 3 radios i have touched into expanded mode and couldn't be happier. The magnum 257hp is one of those radios that people either love or hate, I am on the love boat as I bought one a few months ago and just purchased a 2nd one to put away for now. Next radio is probably going to be an RCI 2970N2. Anyway, good luck and don't think too hard or long about doing the solder bit, it's really a piece of cake.
