Thanks for visiting my website !



I'm an Extra Class Amateur Radio Operator that was first licensed as a No-Code Tech in 1993 • I built this website in 2016 to share some of my experiences in Ham Radio, fun stuff like APRS and setting up a Raspberry Pi 2/3 with a TNC-Pi 2 to send out signals locally and even through the International Space Station • I'll link out to some very knowledgeable Hams that have helped and inspired me to build antennas, antenna mass/polls, and configuring the Raspberry Pi

Raspberry Pi



My very first Raspberry Pi APRS station

Raspberry Pi 2 with Coastal Chip Works TNC-Pi 2, HamMadeParts TNC
Cable
and Baofeng UV-5R V2+ (Not pictured is the portable roll up
Nelson dual band Antenna & GlobalSat BU-353S4)


I used Xastir on very old PC running Ubuntu with a sound modem,
it was natual choice to run Xastir on the Raspberry Pi too.


I'm now using a U-Blox 7 VK-172 GPS and a Leixen VV-898 for the APRS Station.


I recently dedicated a Tram 1481 Antenna for the APRS Station.


I've added many Bells and Whistles to my Raspberry Pi APRS base station,
like booting into Xastir, better maps and much more. Check out the Raspberry Pi
webcam
to see it operating and feel free to download my image file below to
quickly set your own Raspberry Pi 2/3 and TNC Pi 2 APRS station:




Want an APRS Station like mine ?



Free Image File:


      Works for both Raspberry Pi 2 or 3
download (compressed) N9SIR-Pixel-061017.zip file (2.0 GB) here
download (uncompressed) N9SIR-Pixel-061017.IMG file (14.8 GB) here


What it does:


      Raspberry Pi 2 or 3 boots into Xastir • Configured for TNC-Pi 2 (ttyAMA0) and USB GlobalSat BU-353S4 (ttyUSB0), USB U-Blox 7 VK-172 (ttyUSB0) or USB VK-162 (ttyACM0) • Maps (OSM_tiled_mapnik.geo) are installed • The screen saver has been disabled (will not go to blank screen, see webcam for an example) • Xastir Audio Alerts are enabled for New Message, Proximity (0.01 to 1.5 mile) and Weather Alert • Enabled Weather Alerts (visually see bad weather on Xastir map during the SVR_STORM
SVR_STORM
and FLASH_FLOOD
FLASH_FLOOD
alerts).


What to do:


      Download the image file • Format a 16GB Micro SD card (I'm using Trendy's SDformatter, be sure to click the Option Button and choose ON for Format Size Adjustment) • Write the N9SIR-Pixel-061017.IMG file to the formatted 16GB Micro SD card (I'm using Win32 Disk Imager) • Connect TNC-Pi 2, USB GPS, Ethernet cable or Wifi, HDMI monitor, USB keyboard and mouse, then finally the power cable • Watch the video below on how to configure Xastir to your Amateur Radio call sign. You'll need a APRS passcode, get it here.


Please Note:


      If you purchased the "wire and tested" TNC-Pi 2, be sure to "adjust transmit audio output" on the Potentiometer (R7) as explained in the manual (Page 13) and connect a USB GPS too • I suggest using a 2.1A power supply to run the Raspberry Pi with both the TNC-Pi and the USB GPS, if adding a USB camera, run only the camera on a powered USB hub • If Xastir doesn't grab the GPS on the first boot and/or after warm up, move to another USB port on the Raspberry Pi, shut down Xastir and reboot the Raspberry Pi. If moving the GPS to another port doesn't help, try another address (ttyACM0 to ttyUSB0) in the Configure GPS window under the Interface Control • If you change the default password for this image file, Xastir will not start on boot.


Why the Update?


      After a few emails about the last image file not running on some Raspberry Pi 3 units, I started from scratch using a Pixel image file • If you want something added or different on the next image update, please Click Here to Email Me.


No Xastir Boot


      Only for VNC Users without a monitor/display connected to the Raspberry Pi; If you don't want Xastir to start on boot up and want to start/run Xastir in the virtual desktop, follow these instructions • Go to a Terminal window (Ctrl-Alt-t) • At the command line type: sudo nano ~/.config/lxsession/LXDE-pi/autostart • Take out the line: @lxterminal --command sudo xastir • Hit: Ctrl-x • Type: Y • Hit: Enter • Once out of the nano editor and back at the terminal window, type: exit and hit: Enter • Once you reboot, Xastir will not start on boot ••• When you're ready to run Xastir, double click the Xastir icon on the virtual desktop.


Thank You


      Thank you to Tim, KD8LKQ for suggesting Xastir not starting on boot when using VNC • A big thank you to Marty, WD9GYM for supplying the ground work (Xastir on Pixel) for the latest image file.


Next Image File


      Was going to add Winlink but changed my mind, now using PiGate by Mark Griffith, KD0QYN. Please check out PiGate, it's a really nice image file and he even offers a complete setup too.


Open Source


      I'm sharing this image file for those who want to get their feet wet working APRS on a Raspberry Pi 2 or 3 with a TNC Pi 2. Feel free to update and/or modify this image file anyway you'd like and if you decide to share it, upload it to Google Drive, let me know the public URL and I'll be happy to link it on this website.

Excellent Resource for UNPROTO Paths



Want to know more about APRS SSID ?

Excellent Explanation by Bob Bruninga, WB4APR









Sorry, the following is a few of my APRS pet peeves:

Seriously Bad Path

Pilots that send APRS from a plane, please don't Smart Beacon or use multiple hops and paths.
If you're really needing precise tracking, please consider ADS-B Out now, don't wait til 2020 !


Those working APRS on satellites, please don't send half dozen packets/minute during a pass, after
you transmit, take a minute to check if you were heard on ariss.net and if not, try another transmission.
Please give other (newly licensed and low powered) stations an opportunity to be heard too !

Too Aggressive
Aggressive APRS on Satellite
, this Station's (:) satellite APRS was heard every 13 (avg) seconds of a pass.


Just like operating voice, always operate APRS in a courteous manner !

QRPi (20M WSPR-Pi) on the Raspberry Pi 2

A post shared by Tony B. (@crx.ninja) on


I just started running WSPR on a Raspberry Pi 2 with QRPi (20M WSPR-Pi).


There is some good instructions on how to install and run the WSPR program on your Pi,

I'm going to make it easier with this Image File and simple instructions:


Download the Image File • UnZip the Image File • Format a 8GB Micro SD card (I'm using Trendy's SDformatter, be sure to click the Option Button and choose ON for Format Size Adjustment) • Write the WSPR-Pi.img file to the formatted 8GB Micro SD card (I'm using Win32 Disk Imager) • Connect QRPi Whispering Pi board to your Raspberry Pi, connect an antenna to the board and use the following Commands to start transmitting:


Go to a Terminal window (Ctrl-Alt-t) or Putty into your Raspberry Pi
At the command line type: cd WsprryPi
Hit: Enter
At the command line type: sudo ./wspr -r -o -s YOURCALL YOURGRIDSQUARE 20 20m
Hit: Enter


Example of my TX command: sudo ./wspr -r -o -s N9SIR EM86EA 20 20m


Get your Grid Square: HERE or HERE or HERE


Check if you're transmitting at: www.wsprnet.org
Be sure to switch to 20M, enter your Call and refresh the map !
Make an account at wsprnet.org while your there too..


Please Note: I could not WSPR using VNC, I'm using Putty to issue the commands. If you're having trouble establishing a Putty SSH connection to your Raspberry, here is the fix. The above Example of my TX command will transmit every minute which is too much to run unattended and/or around the clock, I usually only run the QRPi for about 5 minutes then take it off the air. I achieved good results just running the QRPi for 5 minutes at 6am and another 5 minutes at 6pm on the same day to see my propagation. Here is my latest results. I'm currently researching how to only TX every 30 or 60 minutes, once I figure it out I'll post the command here.

Current Project



What's going on in my Ham Shack


I've just added a RTL-SDR dongle to the Raspberry Pi 3 that also has the TNC-Pi, was a bit of work but I currently have a single APRS iGate for 144.39MHz (on the TNC-Pi) and 145.825MHz (on the RTL-SDR dongle). I had originally set up the RTL-SDR dongle on another Raspberry Pi networking the data over to Xastir, but it was a bit unstable. I'm going to iGate satellite APRS on the RTL-SDR dongle a week or two, hoping it might handle the doppler shift a little better than the TNC-Pi, time will tell..


I might embed a Blog here to post about the projects,
not sure yet.. Please email me your thoughts on a Blogs.

History


Hello, my name is Frank Anthony, but family and friends call me Tony..


A special thank you to Stanley Holliday (WB9ISY), who exposed me to the world of Amateur Radio. Stanley put a 2M HT in my in my hand, after a a few weeks of listening to the local Nets and the rag chewing, I was hooked. He took me to a Hamfest where we found a the No-Code Technician study guide, a few weeks later I took the exam.


I also like to thank Bill Earnhart (W9MNK), who gave me some good advice on studying for the exam. After receiving my license, I contacted Bill on a local 2M repeater and received a my first QSL card from him a few days later.


I earned ticket on February 16, 1993, right before finishing college in Indiana. When I got back to Tennessee, I joined the Oak Ridge Amateur Radio Club (one year) where I ran to an old friend, Todd (KE4EQR - Silent Key). I worked a few events with Todd's Radio Club (think it was RACK, providing communications for Knoxville Track Club), worked some Packet Radio using BayPac Model BP-1 Modem, worked a few Field Day events, then between the start of a family and broken equipment, I stopped keying the mic..


Fast forward to 2015, with my Son gone off to college and us not kart racing anymore, I needed to find a hobby.. So, I decided to get back into Ham Radio. I soon purchased a cheap (2M/70cm) HT and (2M/70cm) base radio and with the help of my friend, Larry Noe (KM4ITU) I finally figured out how to program all the local repeaters. I'm currently using 17' Tram 1481 (2M/70cm) antenna attached to a 20' foam filled PVC mass, I also have three roll-up dual band (2M/70cm) antennas by Nelson Antennas. I've built the $4 dual band yagi for working the satellites and local nets. I also have a really nice (2M) J-Pole that my friend, Joe Johnson (W4OWR) built me a few years ago, trying to figure out how to mount it on my van (with an electric actuator) for camping trips, emergency nets and volunteer events.


Currently, my interests are working APRS (iGate and SatGate), working voice on satellites (QRP), building an APRS Go Box, meeting some new folks, attending a few Hamfests and I'm really look forward to visiting another Field Day in 2017. Now that I'm a Extra Class, I'm looking into building or buying some low cost HF equipment. Hope to have a few HF QSOs with my old neighbor, Keith (N9SIQ) who took the No-Code Tech Exam on the same day I did. I'm currently a Member of the Sevier County ARES Group and a Technical Advisor for the University of Tennessee Amateur Radio Club. I'm also a full-time Volunteer Examiner (VE) for the W4VEC in Sevierville, Tennessee and occasionally for the ARRL in Knoxville, Tennessee.
