Tnx reply. Don't know why I said pre-AGC. Manual clearly says post AGC.
Wasn't worried about too much voltage. Rather concerned about too little-- given that the output is intended for sound card inputs. Was hoping to identify if this were a problem before arrival. Will do the measurements after the K3 arrives. The measurements will be "plug in TNC". Hopefully LIN OUT will have enough range to get to the -3dbV my current line out audio source provides. 73 de K3KO Lyle KK7P wrote: > >> Anybody know just what the voltage range can be put out at the line out >> jack? >> >> Since it is pre-AGC it isn't a "constant level" output but instead varies >> with signal strength.
