There are plenty of videos showing the mods, but IMO, it's best to send the radio to a good tech and have a tune and alignment done and also have variable RF power installed like JJD has his. Great spot for it as you don't ever really turn the delta tune knob on that radio!! There are a few good techs and out there. Screwdriver at Bells CB, Doug's custom CB, Mikes Radio and Repair, Key CB, and a few others that do a good job and have the proper equipment to do them the correct way!! But if you want to mess with it, just google the mods for a 29lx. There is a bunch of info. Be careful inside the radio! And like I said, if you are serious about messing around for a while in the hobby it's either buy the proper equipment to tune and align a radio or find a good tech and have them do the work. Either way you are going to pay LOL! Not being harsh, just truth is all man!!!! Have a good one and be safe inside that radio if you mess about. No metal screwdrivers!!!
