APRS, RTL-SDR & Dire Wolf
An updated 2018 guide to setting up an APRS receive-only iGate using a Raspberry Pi, RTL-SDR dongle and Dire Wolf, by G6NHU.
Notes and pointers for UI-View32, APRS iGates, and the n-N paradigm. Newer sketches (LoRa APRS) live under APRS UK.
2017: New APRS Products
A couple of APRS products from that year:
HF APRS using PSK63
Stephen WA8LMF has written guidelines on setting up PSK63 APRS.
IARU Region 1 adopts the new n-N paradigm
At the November 2008 conference, TRACE n-n versus WIDE n-n was discussed and IARU agreed that Region 1 should adopt the new n-N paradigm.
The UK and other countries should switch to traceable WIDE n-n digis. Users should update their unproto to APRS,WIDE3-3 [Home] and WIDE1-1,WIDE2-2 [Mobile].
UI-View users should check uiview32.ini and confirm it has UITRACE=WIDE and UIFLOOD=TRACE (the opposite of the installed default). The alias section (ALIAS=) should include WIDE1-1 and WIDE1.
Having a go with UI-View & APRS
Registering UI-View32 and the FAQ.
If you already have packet radio equipment, download the freeware version of UI-View.
If you don’t have packet gear but do have a PC and soundcard, download the freeware AGW Packet Engine for a 1200 baud packet modem, then configure UI-View to talk to AGW.
