CPDR:
click to enable the compander and adjust its level with either the slider or the text box.
VOX:
click to enable the VOX and adjust its level with either the slider or the text box. See also
the Setup Form-Transmit Tab (page 113). When enabled, a bar graph will show just below the
slider control. The green part of this bar graph shows the portion of the sound level that will not
activate the transmitter; the red part the portion that will. VOX should be adjusted such that
ambient noise will not activate the transmitter, but a normal voice will.
GATE:
click to enable the Noise Gate and adjust its level with either the slider or the text box.
See also the Setup Form-Transmit Tab (page 113). When transmitting, a bar graph will show
just below the slider control. The green part of this bar graph shows the portion of the sound
level that will not open the Noise Gate; the red part the portion that will. The level should be
adjusted such that ambient noise will not open the Noise Gate, but a normal voice level will.
Hint:
The Noise Gate can (and should) be enabled in all situations where
ambient noise will render your transmissions less clear, irrespective of
whether VOX is engaged.
Transmit Profile:
select the transmit profile to use for phone transmissions. The default
profiles are
Default
and
Default DX
. See also the Setup Form-Transmit Tab (page 111)
Show TX Filter on Display:
when checked, the band edges of the transmit filter, set on the
Setup Form-Transmit Tab (page 112) will be shown as 2 yellow lines on the display when set to
Panadapter. It can be an especially useful visual aid when operating split to position your
transmit frequency where desired (in a pile-up) using VFO B (or VFO A sub-frequency when
RX2 is on). Additionally, it will give you a quick visual impression of whether your transmit filter
needs to be adjusted or not.
RX EQ:
activates either the receive three-band or ten-band equalizer. See also the Equalizer
form described on page 139.
TX EQ:
activates either the transmit three-band or ten-band equalizer. See also the Equalizer
form described on page 139.
VAC:
activates
Virtual Audio Cable
http://software.muzychenko.net/eng/
), a third party
program (written by Eugene Muzychenko) to enable digital audio transfer between PowerSDR
and other third party (digital) programs. See also the Setup Form – Audio Tab, VAC Sub-Tab
described on page 92. VAC is not automatically enabled for phone modes, even if
Auto Enable
has been checked on the VAC Sub-Tab.
CW Controls
The CW controls, shown in Figure 44 below are available when either CWL or CWU is selected. Most of
these controls can be found on the Setup Form-DSP Tab, Keyer Sub-Tab (see page 106, where you can
also find a more detailed description).
