Transmitting
Tune
The "Tune Power[%]" spinner allows you to select the power output used when the "TUN" button is
pressed on the main OpenHPSDR/PowerSDR window. In some versions of OpenHPSDR/PowerSDR, this
is actually a percentage of power output rather than output in Watts. The "Tun" button places
OpenHPSDR/PowerSDR in CW mode and keys the transmitter using the specified power output level.
The "TX Meter:" drop down selects what the TX Meter on the main form displays when the "Tun" button
is pressed.
VOX
Click the "enabled" button to enable "Voice Operating Transmit" if you want to cause the transmitter to
key when you speak.
Set the sensitivity spinner to a higher value if your wish to have a higher voice level cause the
transmitter to key.
Set the delay to cause the VOX to de-key the transmitter after not hearing voice for "Delay [ms]"
milliseconds.
Use this with care. Local noises [dog barking, TV playing, door bell, computer sounds] can cause your
transmitter to key when you do not want this to happen. Extreme cases can cause your transmitter to
key for excessive periods of time resulting in damage to your radio and attached power amplifier.
Transmit Filter
This filter tailors the transmitting frequency response in voice modes.
The default for high is 3100hz in some versions of OpenHPSDR/PowerSDR.
This value exceeds the frequency response allowed on 60 meters in some regions.
You can modify this and other values as needed before hitting the "Save" profile button to save to disk
for later recall.
