Step-by-step

These are the high level steps to build your very own 1-port TARPN node. Some steps link out to a more detailed guide, since this page is your one-stop overview.

1. Build or buy a NinoTNC (about ~$40 in parts)
   • Buy the PCB on Etsy, and necessary components. Then follow these detailed construction steps.
   • Or ask if you can buy an assembled NinoTNC from an existing TARPN member, who often have spares.
2. Acquire an appropriate VHF or UHF radio
   • Any VHF/UHF radio can be used so long as you can buy or make an audio/PTT connection cable for it (see this homebrew Kenwood cable). Even a basic Baofeng UV-5R can be used with a homemade cable, though it's limited to 5 watts. The radio suggestions below are higher power.
   • Most TARPN members buy inexpensive used commercial radios by reprogramming them for ham radio frequencies.
   • Here are eBay searches for some popular models known to work well with TARPN (fast PTT switching speed):
     • Kenwood TK760H, Kenwood TK762H, Kenwood TK805d, Kenwood TK862G TK862H TK862HG, Vertex FTL-1011 (6 meter), Tait TM8105.
3. Buy a Raspberry Pi.
   • Any full-size model will work just fine except "Pi 1 Model B rev 1".
   • Avoid Zero and Compute Module versions, which are more complicated to use and may not be compatible.
   • You can see the full list of supported models.
