(16) MOX (Manually Operated Transmit)
When enabled MOX activates the transmitter. It is used primarily for voice operation. MOX will not
generate a CW carrier. To generate a carrier for tuning, refer to the tune (TUN) button description on
page 73.
Note 1: If the radio ever seems like it is stuck transmitting, try disabling the
Push-To-Talk (PTT) function by selecting Disable PTT on the Setup
Form-General Tab, Options Sub-Tab.
Note 2: To use PowerSDR without any hardware attached to the PC you must
disable PTT. On the Setup Form-General Tab, select either Disable
PTT on the Options Sub-Tab, or Demo/None on the Hardware
Config Sub-Tab
(17) MUT (Mute)
This button Mutes the speaker audio. (If RX2 is installed and on, it will mute both RX1 and RX2.) The
receiver(s) may also be muted by pressing the * (asterisk) key on the keyboard.
(18) Rec (Record) and Play
The Rec and Play buttons offer a quick and easy way to record and play back a signal audible on the
main receiver RX1. Click Rec to record a signal and click Rec again to stop recording. Once recorded,
the signal can be played back by clicking Play. Subsequently clicking Rec will overwrite any audio file
previously recorded in this way. The Rec and Play buttons are the same as the QuickRec and
QuickPlay buttons on the Wave Form (see page 137)
Note: The audio file is saved as SDRQuickAudio.wav in the same directory
where your PowerSDR.exe file resides. The saved file contains post-
processed audio, and can be played back with any wav file player.
(19) TUN (Tune)
Without the automatic antenna tuner (ATU), TUN transmits a continuous (CW) carrier at the
level set with the Tune Power control (default 10W) on the Setup Form-Transmit Tab (page
111) and outputs a tone at the CW Pitch. This power is shown on the Drive control while TUN
is activated. Any changes to the Drive control while TUN is active are saved when the TUN
button is turned off. This feature is used to simplify the antenna tuning process for proper load
matching.
With the ATU, TUN activates the ATU tuning function. When the ATU is in Bypass, the TUN
function operates just as if the ATU were not present.
