Allan the Omni V.9 installation info can be found at: http://www.hal-pc.org/~kg5u/OmniV9.html Some recent posts have a key re-label option that precludes removing the keypad. It works great and I use "Logger" as a logging program and an RX-320 as a secondary receiver off the Omni V.9 receive antenna! The software for that was also developed by Karl (N4PY). Well worth the effort. 73, Rick
