View source for AX.25: TinyTrack4 Digipeater

 TinyTrak4 as fill-in digipeater
I was thinking, why do I need to power on my PC when someone already gated the packets out to the net. What I want to do is to escalate/repeat packets sent by APRS stations from "Bermuda" area of Sg Buloh to the digipeater-to-be somewhere at Genting. Since I've Argendata Tracker2 already, I was thinking, why not try the Byonic TinyTrack4 and have it run in standalone mode and acts as a digipeater. So, ordered mine through 9W2PD (bulk order) and received it early of the week.

The hardest part for me is to set the TT4 to recognise incoming packets. When I received the TT4, I could not get it to recognise any packet, so put off by it .. I didn't touch it for few days (+ the busy days debugging BSP/ABAP Object/middleware and stuff related to work that it). To get it working with my FT-60R HT, I need to set the SQL all the way counterclock wise (off), set the volume to 25%, RXAMP and CDCODE and CDLEVEL as the configuration shown below.

My configuration is: Tinytrack4 + Yaesu FT-60R, configuration as I put into the software (Alpha 0.51 firmware), the important fields to get the digipeater working are in bold:

300 is FALSE
TXTDISP is FALSE
NODISP is FALSE
PPATHING is FALSE
DMSDISP is FALSE
MICETMV is FALSE
ENTS is FALSE
TELHIRES is FALSE
TELVOLT is TRUE
TELTEMP is TRUE

TIMEHMS is TRUE
SBEN is FALSE
TSWPT is TRUE
AMODE is TEXT
BMODE is TEXT
ABAUD is 19200
BBAUD is 4800
SSIDROUTE is 0
ALTNET is APTT4
MYCALL is 9W2TPT-4
DIGI1 is WIDE1-1
DIGI2 is WIDE2-1

ALIAS3 is
DUPETIME is 30
FILTERCALL is

Update: aprs.fi doesn't like the beacon text w/o '>', so, added it manually to the beacon text line.. don't see this with Tracker2 though.

Update 2: According to Byon, the only required parameter to enable the digipeater is the ALIAS1. The rest are just supporting parameters.
