Gentleman, I believe I have found the cause and the Cure for the Galaxy radio drift.
I will use the clarifier on the ranger 2950 versus the Galaxy dx2547 for instruction purposes. The Galaxy's all use a zener diode in its clarifier section that is an SVC 251. It has a rollback voltage of minimum 12 volts. That means that at 12 volts or higher it becomes unstable. The ranger has a svc201 which does not become unstable until 16 volts or higher.
