Having read this many times, I still cannot understand what you are asking for.
what do you mean by
“I am trying to make the NAV morse replace the COM radio.”
and why ??
Maybe you mean "I am trying to make the NAV morse AS LOUD AS the COM radio. ?
In that case,
(1) I 100% agree with you, the maximum Nav radio Morse audio level is far to low, compaired with the max COM radio audio
(2) Also do not now how the Morse is generated. Programmatically by a software tone generator, or from an Audio file.
If it is a user available audio file, then maybe even the user can edit that file to bump up its amplitude – or if not available to the user, Maybe Asobo can increase the Max Nav audio, by a good x2 , or more ideally, to the SAME max amplitude as the COM radio, and then , as in RL, the user can adjust the balance by the COM & NAV volume controls.
LOW Nav Audio has been an issue with MSFS, since release date
While looking at this, how about introducing some NOISE on the Nav Morse audio, as the source is approaching maximum radio detection range. ??
I wasn’t quite sure how the morse code would work in the radio. I thought I had to switch of the com audio to hear the morse code. I have tested a few radios of planes in game and that doesn’t seem to be the case.
The question then is why is my morse code not being heard? I have the nav frequency, the ident and Nav Sound ON in SimvarWatcher…
