| - | __**What you'll need to complete the assembly**__\\ | ||
| - | 1. Raspberry Pi 2.0 Model B or Raspberry Pi 3.0 or Raspberry Pi 4.\\ | ||
| - | 2. 2 amp (minimum) power supply w/micro USB connector\\ | ||
| - | 3. Ethernet cable.\\ | ||
| - | 4. WiFi USB dongle. You only need this if you're using an Pi 2.0 and you want to use WiFi. \\ | ||
| - | WiFi is built into the Pi 3.0.\\ | ||
| - | 5. SD card (4 GB min, grade 10)\\ | ||
| - | 6. SD card reader (micro SD card to USB)\\ | ||
| - | 7. antenna mate to SMA connector\\ | ||
| - | __**Programming an SD Card**__\\ | ||
| - | **Setup**\\ | ||
| - | 1. You need an SD Card; at least 4GB, 8GB is better. Class 10.\\ | ||
| - | 2. SD Card reader/ | ||
| - | reader/ | ||
| - | 3. Win32DiskImager – It's a freebee. Download it from:\\ | ||
| - | https:// | ||
| - | sourceforge.net/ | ||
| - | 2. Install Win32DiskImager.\\ | ||
| - | 3. Disk Image – Download it from:\\ | ||
| - | WSPR SD Card Image for Pi 2, 3 [[https:// | ||
| - | WSPR SD Card Image for Pi 4. | ||
| - | 4. Unzip the file after it's finished downloading (it will take a while).\\ | ||
| - | |||
| - | __**Program SD Card**__\\ | ||
| - | 1. Plug the SD Card reader/ | ||
| - | 2. Plug the SD Card into the reader/ | ||
| - | {{: | ||
| - | 3. Start Win32DiskImager.\\ | ||
| - | 4. Click on the folder icon in the upper right and find the disk image you downloaded and | ||
| - | unzipped.\\ | ||
| - | 5. Click Write and go get a cup of coffee. Note: Win32DiskImager shows a small message box | ||
| - | when it's done writing the SD card. Unfortunately, | ||
| - | anything else you have up on the screen so you can't see it. Be forewarned that you might have | ||
| - | to go looking for it.\\ | ||
| - | 6. Click Exit.\\ | ||
| - | 7. Remove the SD card and install it into the Pi. Make sure that power is disconnected from the Pi | ||
| - | before doing this\\ | ||
| - | \\ | ||
| - | If you haven' | ||
| - | will work!\\ | ||
| - | |||
| - | __**Install SD Card into Pi**__\\ | ||
| - | First, insert the SD card into the Pi \\ | ||
| - | The SD card sorta slides in up side down. \\ | ||
| - | On Pi 2.0 it ratchets in (pops in then out a little and sorta locks in place). \\ | ||
| - | On Pi 3.0 there' | ||
| - | \\ | ||
| - | __**Setting WSPR Configuration**__\\ | ||
| - | {{: | ||
| - | 1. Open a web browser (Internet Explorer, Firefox, Chrome, …) and type in the IP address of the Pi (192.168.0.67 for example).\\ | ||
| - | This will bring up the configuration screen shown in | ||
| - | WSPR Configuration Screen -\\ | ||
| - | 2. Enter your callsign and gridsquare parameters.\\ | ||
| - | 3. Enter the SSID and passkey (password) for your WiFi network. These are what you use to | ||
| - | enable your cell phone and things like Roku to use your home network. If you don't know what | ||
| - | they are you'll have to go digging through your router to figure them out (see the | ||
| - | Troubleshooting section).\\ | ||
| - | If you elect to not use WiFi then you don't need to enter SSID and Passkey. You will have to | ||
| - | keep the Pi connected to the network by Ethernet cable because the Pi uses the Internet for time | ||
| - | synchronization.\\ | ||
| - | 4. Check/ | ||
| - | A WSPR message takes just under two minutes to send. The fastest you can send WSPR | ||
| - | messages is every two minutes. It's considered bad form to flood the WSPR servers with | ||
| - | messages. The default is to send a WSPR message every ten minutes. If you check the transmit | ||
| - | every 2 mins checkbox then messages will be sent every two minutes. This setting is useful for | ||
| - | testing and short term experiments.\\ | ||
| - | 5. Set the Transmit Power and Transmit Band to 23 dBm and 30m for 30m and 20 dBm and 40m | ||
| - | for 40m.\\ | ||
| - | 6. When all done click on the **update button**. \\ | ||
| - | This will store the data on the Pi.\\ | ||
| - | \\ | ||
| - | __**Restart Pi**__\\ | ||
| - | 1. Press the pushbutton on the Kit board. Hold for two seconds and release. This commands the Pi to | ||
| - | enter shutdown mode (you' | ||
| - | system can be damaged – pulling the plug is bad).\\ | ||
| - | 2. Unplug the power supply, wait 10 sec, then plug the power supply back in and wait until the | ||
| - | LEDs on the Pi stop flashing\\ | ||
| - | |||
| - | __**Measure RF Output**__\\ | ||
| - | The LED on the WWoT turns on when the WWoT is transmitting. Wait until the LED is on and | ||
| - | measure the voltage across the test points labeled RF Level and Gnd. This should be in the | ||
| - | range of 3-5 volts, indicating the WSPR transmitter is generating full power.\\ | ||
