The stand alone TX-500 stand was made as a request from one of the diy599 group guys. It is a convenient way to keep the TX-500 at home and is more flexible from an angle point of view compared to the built in stand. This version is the desk version. There will be a field version, which has an extended base to handle more extreme angles with all the cables attached. This version is much more convenient when space is tight on the radio bench.
