Quick Guide for WSPR Desktop transmitter
Setting the configuration for the Transmitter.
1. Download and install the Configuration software from my web
www.zachtek.com/download
2. Connect the USB port of the Transmitter to a PC with the USB
cable and connect the included GPS antenna to the GPS input.
Put the GPS puck near a window to get a good GPS signal
3. On the other side of the box connect a suitable HF antenna to the
port marked Transmitter Output
4. Start the configuration software and choose a Serial port from the
drop down list.
5. Click the “Connect” button. If the serial port was the correct one
then the software will pull data from the Transmitter and display
the data from it in the Software.
If you have several serial ports in your PC, you may have to try to
connect to each of them in order until you find the right one.

6. Set your call sign and enable the bands you want to transmit on
then click the Save button.
7. To verify your settings have been stored you can close the serial
port and then open it again, this will re-read all the settings from
the transmitter and you can verify that everything is correct.
8. To start the WSPR beacon click the “Start” button in the WSPR
Configuration section as shown in the picture.
9. Once the WSPR mode has been started it will continually
transmit the WSPR beacon on all bands that are enabled.
If you change something in the software, it will drop out of WSPR
beacon mode and you have to click the Start button again.

Running the Transmitter standalone
1. The WSPR Transmitter will either start in WSPR Beacon
mode, in Signal generator mode or in idle mode depending on
what the start mode is set to in the configuration program, see
picture.
If it is set to WSPR Beacon, it will continuously transmit as set
in the configuration.
The Yellow status Led will indicate what it is doing at the
moment.
Yellow LED Off= Waiting/Idling
Yellow LED Single blinking=Acquiring position from the GPS
Satellites.
Yellow LED Double blinking=Waiting for top of even minute.
Yellow LED Pulsating rapidly=Transmitting WSPR packet.
I hope this information is enough to get you started and get you on
the air. If you need more information, check out the documentation
pages on my website or email me at [email protected].
See you on the bands!
