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:

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.
