I'm just just basing the audio setting on where I have it set when I use
DAX. I run the level all the way over till it just barely touches the O
db level on the SmartSDR panel. I set DAX about 65. With WL it only goes
up to a little over -10db. I can use it there no big deal. Al long as it
works. I don't have any problem getting power out of the amp.
What about the TX lockout?
Thanks

What that slider all the way over, MMTTY is delivering rail-to-rail
audio. (In the Windows audio world,
digitized audio has a definition of a maximum amplitude which I am
calling a "rail".) Driving the Flex
with that through its DAX channel, there cannot be a reason to raise it
any higher.
If you want more power out of the transmitter, push the RF Power control up.
Exactly, what is there about the audio level that you do not like?
On a related topic, by the way, there is no technical reason for this
AFSK data flow to leave you with
FSK envy. The full digital data flow is digital. Every single amplitude
sample sample coming out of the RF
port was calculated digitally. The quality of the on-air signal is
effected NONE by any amplitude settings
you might have. This is in contrast to the analog setup commonly
described as AFSK where MMTTY drives
a hardware sound board whose analog output, in turn, is fed into a
microphone or maybe a line in on
an SSB transmitter. Such a setup does have an analog amplifier with a
gain knob on it, and whose incorrect
(i.e. extreme) settings likely will cause nonlinear behavior, which
distorts the output.
