Greetings,
Several months ago I realized that if I could have some keyboard
shortcuts to adjusting the sound-card input and output levels, it would
greatly streamline on-air operations. I use Windows XP Pro at my radio
station, and a search of the 'net yielded this excellent free tool
called "Sound Control". I installed it and customized the keyboard
shortcuts to my liking, and it works great. You can download it (for
Windows systems only) free from:
http://www.reallyeffective.co.uk/sound-control/
Dave's addition of an output control is icing on the cake for me. Now
(even with the Sound Control application) my output fader is closer to
mid-range when I set Fldigi to -12 dB, and it works better. The Fldigi
internal keyboard shortcut is nice too.
Perhaps there is a Linux tool similar to Sound Control that someone can
tell everyone about.

The TX level output control is a blessing! It's the final touch to

to use the same settings for both voice and digital modes without
readjusting the mic gain. On my setup the RigBlaster audio control is
very
touchy. Having set it to the very lowest setting that would provide
output
without overdriving the mic stages it meant keeping the mic level at
below 3
(8:00 position) and required me to turn it up to the 12:00 position
for SSB.
This is a great fine-tuning control!
The matching Input control for RX with some gain would also be a nice
touch!
Thanks,

The Tx Level control is really a digitally implemented attenuator.
Not possible to do the same with Rx. The need on Rx is to control the
analog signal level before it reaches the A/D converter. That
requires access to the mixer stages of the sound card h/w.
