Line 1: Line 1:
-__**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/writer. We've got a Targus Micro SD/T-F. It doesn't really matter what card\\ 
-reader/writer you use. It connects your SD card to a USB port.\\ 
-3. Win32DiskImager – It's a freebee. Download it from:\\ 
-https://sourceforge.net/projects/win32diskimager/ or\\ 
-sourceforge.net/projects/win32diskimager/.\\ 
-2. Install Win32DiskImager.\\ 
-3. Disk Image – Download it from:\\ 
-   WSPR SD Card Image for Pi 2, 3 [[https://files.tapr.org/product_docs/WSPR//TAPR%20WSPR%20Image%20for%20Pi%202%20or%203%20-%2011Feb2019.img.zip]]\\ 
-   WSPR SD Card Image for Pi 4.   [[https://files.tapr.org/product_docs/WSPR/TAPR%20WSPR%20Image%20for%20Pi%204%20-%2001Apr2021.img.zip]]\\ 
-4. Unzip the file after it's finished downloading (it will take a while).\\ 
- 
-__**Program SD Card**__\\ 
-1. Plug the SD Card reader/writer into a USB port.\\ 
-2. Plug the SD Card into the reader/writer.\\ 
-{{:windisk.jpg?400|}}\\ 
-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, the message box likes to hide behind 
-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't annoyed the gods of the Internet too much today you should be in luck and everything 
-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's a friction fit, so there's no locking.\\ 
-\\ 
-__**Setting WSPR Configuration**__\\ 
-{{:wspr_config.jpg?400|}}\\ 
-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/uncheck the transmit every 2 mins checkbox. (I recommend leaving it unchecked.) 
-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're always supposed to shutdown a computer properly or the file 
-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.\\
