Bob,
Thanks for that info, a much more elegant way to control the emu0202
audio output. I had to use the Contol Panel approach to gaining
access to the speaker dialog box. Adjusting the "WAVE" slider to the
first mark at the bottom and K3 "MIC" level to 20 was perfect setting
to obtain ALC 4-bars+ 5th blinking that is desired. Nicer to plug
audio line into back output jack and leave headphone jack for normal
use (which I use).
I am running JT65B under WSJT for 2m-eme and one feature that I could
not use was the moon "ECHO" mode. That mode allows you to send a
short carrier to the moon and receive your own signal to measure
overall system performance. The Tx/Rx sequence only lasts 2-seconds
and with the K3 ramping up power taking 4-5 seconds this mode was
unusable. Besides overdriving the K3 in DATA-A is not nice.
Computer is Dell 2.33 GHz duo-core2 running XP32. BTW running the
emu0202 is very handy with having real physical control pots for
setting receive audio level as noise can change this at any time and
being able to reset this for the spectrum waterfall display is VERY
handy. Transmit audio only needs to be set once and forgotten.

If you are using Windows, there *is* a way to adjust the emu0202 output
in software. It's not by using the EM-U control panel app but by using the
Windows Volume Control applet instead.
I'm using an emu0202 with Windows XP.
Either access the Windows Volume Control from the task bar
or
Navigate to Control Panel->Sounds and Audio Devices. Select
the Audio tab (not the Volume tab where the controls are grayed
out) and you should see the emu0202 as the "sound playback"
device. Click on the Volume... button to open the Speaker dialog,
where you can adjust the output level. With mine set to the 2nd tick mark
from the bottom, the mic level control is set to 16 or 17 to drive
the K3 to 4-5 bars input in DATA A mode.
If you are running Windows 7 things may be a bit different.
No, the emu0202 instructions don't mention how to do this.
