Anan 10-E random unkeying?

[cleanrf]

Running Thetis accessed from 3 different computers, no shared databases amongst them same issue with any of the computers. I use the radio into a homebrew LDMOS amplifier and have been for years, in the last few months people will tell me I unkeyed mid transmission and the radio still appears to be working on the computer screen. Unkey and key back up and I am back. After testing it appears to be happening in the radio. I was just curious to see if anyone else has had this issue?

Thanks

I also notice this doesn't seem to happen as often if I have the Drive on the anan backed down to around 25% or so.

What happens when you use the Anan without the amp? (antenna directly connected to the Anan)

Does the same thing with amplifier out of line.
