Would like to acknowledge the great service I have received from Jason Smith at Aerotronics. They built my panel years ago and I recently had some issues with my ADS-B (pointed out to me by a friendly call from the FAA). When I called them they said to ship them my transponder, did a no charge software update and sent in back..... and the problem was worse than before. When I reached out for help getting things working I felt like I was their number one customer and that when I called they dropped whatever they were doing to chat with me. They were very helpful and helped me work through the issue and get it fixed. While I did spend a fair amount of money with them years ago, it certainly wasn't a "warranty issue" and I feel they really went above the call of duty. Thanks guys
