Give him a call. His phone number is on his website. He will tell you how much you will be looking at with return shipping. I just got a HR 2510 done by him. It needed a lot of improvements. I'm hoping it arrives today.I have the HR251 President version. I bought it new with the chip-switch and unlocked clarifier. It has been my favorite radio. I wrote Doc' and told him I wanted it looked at. Don't seem anything is wrong; but I would like things aligned. Does anyone know how much he charges.I know you get what you pay for. Thank you.
