I have put together a short 'How To' document to modify ICOM Dstar Repeaters for a discriminator tap and PTT switch and some test procedures. These mods can damage your repeater and are not recommended or endorsed by Icom. I have had good success with them and am sharing to help other system owners / operators. The paper is in html format at http://www.bosshardradio.com/dstarrepeatertesting/dstarrepeatertesting.htm or tiny url http://tinyurl.com/7ky7aj . You are welcome to share or repost as you wish. Your mileage may vary.
