I am using a 6600M and I have had two occurrences of not being able to transmit; The TX button would not turn red when pressed.
The 6600M ATU was set for Byp.
Pressing the Tune button did nothing.
I changed the ATU to Tune and it automatically started to adjust.
When tuning was completed I pressed the TX button. It lit red and when I pressed Tune the 6600M started to transmit.
My question is, does the 6000 series internal tuners, when in Byp, actually go to a neutral position?
Or, is this some sort of Software/Hardware issue??
