Harbach Electronics is closed permanently
by Dave Schmidt 31 Mar '24

31 Mar '24

Saw it posted on the QTH for sale section, went to the website and it's confirmed. ***Harbach Electronics Closed Permanently*** 28 March 2024: Due to being diagnosed with Parkinson’s Disease, Harbach Electronics will be permanently closed. I am exploring options for someone to keep the business going and if that works out, great, if not, it has been a great run for 27 years since I took over from Al Harbach, WA4DRU. I am officially closed and any outstanding orders will be cancelled and refunded. I am leaving work on a medical retirement and moving to Florida. 73 Jeff W8CQ Dave AI6VX

Calli, Here's that microphone chip I was talking about. https://www.analog.com/en/products/ssm2167.html I learned about it when I was looking to add an amplifier/compressor to my FT-817 and ran across this product. https://www.box73.de/product_info.php?products_id=945 and here's the magazine article on the chip. https://www.box73.de/file_dl/bausaetze/BX-817_3_w.pdf Dave AI6VX
