====== HF APRS Base Station ======

** Direwolf TNC iGate on 30m **

===== Using Direwolf on HF =====

  * 30m APRS frequency = ''10.1476MHz'' USB / ''10.151MHz'' LSB (using 1.7kHz modem frequency)
  * RF centre frequency = ''10.1493MHz'', tones ±100Hz
  * Direwolf acts as 
    * TNC/Modem to send and receive packets via HF transceiver
    * Internet I-Gate 
    * Tracker, when configured to use **gpsd** to provide real time GPS position
    * Network (AGWPE) TNC for other APRS client software

==== Direwolf running (in a Tmux session) ====

{{:public:radio:direwolf.png?direct&600 |}}


===== Xastir using Direwolf as TNC =====

  * Direwolf can act as a network TNC for other clients
    * Uses "AGWPE" protocol

Set Xastir on another PC to use Direwolf as TNC. This gives user access to APRS - map, messaging etc.

FIXME

===== APRS.FI =====
