Flex is keying by it seft. Will be listening to it and it gets quite and look at it and it is keyed. It was unkey and went into house, came back out and it was keyed. This has happen 4-5 times.This is the 6600 M.
using it on SDR, Check Vox and it is off. Last 2 times I saw that the Mox light on, That is next to the tune. All I had to do was click it and it unkeyed. Of course that is where you key it. The red light will be on too where power button is. Am using a Heil mike and it is hard wire with a push button, and it will not be key thru it.
