I have the 6300 connected to the 922a properly, but when I move the amp to operate, it keys the amp???
With the behavior you describe, it is most likely that you have caused the keying device (transistor or other) to fail in a shorted condition inside your 6300. Time to open a help desk ticket and let Flex sort it out for you, which will most likely result in sending it back to them for repair. Older amps, like the TL-922A. draw far too much current on the keying relay coil for modern day transceiver keying circuits (Flex is no exception). The ARB-704 is an absolute necessity, so get one before you get the 6300 back from repair!
