I sent my dead Kenwood TH-78A HT to Darren to tinker with to see if he could revive it after Kenwood was unwilling to do so many years ago. He replaced a few parts and cleaned up some things. I got the radio back this week and after buying a new battery (original was way beyond taking a charge) it seems to be working great! I recorded my transmit audio on another radio and it sounded great. Receive signals sound good as well. Darren did a great job and was a pleasure to work with. His repair and shipping fees were very affordable. Thank you Darren!
