Fixes in installation instruction: R44,R45,R46 needs to be installed (was invisible on layout); the 5V side of R50,R52 needs to be disconnected and wired to pin 21 (not pin 25! and description wires with circles was ambiguous); better to remove R27,R29,IC10 to prevent side-effects from interconnecting potential old unused circuitry; TNX PA3FUN, G8EMA.
