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

Listen to actual APRS packets heard by my Station,
my average ALOHA radius is 103 miles.

Raspberry Pi

First Raspberry Pi 2 APRS Station

Raspberry Pi 2 with Coastal Chip Works TNC-Pi 2, HamMadeParts TNC
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
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:

Free Image File:

      Works for both Raspberry Pi 2 or 3
download (compressed) 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

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 ••• If you ever want to run Xastir, double click the Xastir icon on the virtual desktop.

Thank You

      Thank you to 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.

Longer Video of the APRS GoBox:

Built with a Monocular Night Vision Ammo Can (Case OD: 6" wide x 13" tall x 11" long): Price $29.99 • 35Ah Battery (12V UPG Universal Power Group 45976 Sealed Lead Acid): Price $64.99 • Raspberry Pi 2 Model B: Price $39.50 • TNC-Pi 2 (Coastal ChipWorks): Price $65.00 • Official Raspberry Pi 7" Touchscreen LCD Display: Price $79.00 • TNC Cable-MIC Jack to DB9 & 1/8" Spk Plug (eBay: hammadeparts): Price $19.95 • Jetstream 2M/70cm (10W) Used Price $40.00 • I will charge it in the field with a 45W solar (3) panel setup with a battery controller (Harbor Frieght): Sale Price $119.99 • The total GoBox cost (not including the solar panels/charger, miscellaneous connectors and power wires) was $338.43 • I really enjoyed designing and building this project, I purchased all the parts over a six month period to spread out the cost • My next project will be getting this Go Box to also operate FLDIGI by adding a USB to the front panel, to plug in an USB sound card with a "EASY DIGI" Sound Card Interface to a Baofeng (8W) BF-F9 V2+ operating transmit By VOX..

Picture of the Go Box running FLDIGI/FLMSG:
(using a HT, I've since re-wired the Easy Digi interface for Go Box radio)

Just setup the APRS Go Box for FLDIGI, had to use a HT (vox) because I haven't finished the TX trigger circuit for the mobile that's mounted #amateurradio #hamradio #fldigi #gobox

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 the University of Tennessee Amateur Radio Club, I'm also a Volunteer Examiner (VE) for the ARRL and W4VEC.
