I have a problem with two T3-Mini that I installed on a Alinco DR-135 radio thru the back DB9 port. The USB port is plugged to a TP-Link router to act as gateway.
The first T3-Mini was operating since February for 2 months and in April it stopped beaconing and digipeating, also the USB lamp on the TP-Link router turned off.
After I removed from the radio and the router a
nd plugged to the laptop that I use to configure this board, the board was undetected.
So I thought the board is dead, so I replaced with another T3-Mini
Last week, I noticed that there is no APRS traffic passed to the Internet, so I check the router and found that the USB light was off. I unplug and replug the USB cable to bring the port up but still the USB port down.
This time, the board still beaconing and digipeating (so it is alive), but the USB port is down, even when plugged to the above mentioned laptop.
So, I think I have 2 T3-Mini that went dead in a very short period (as compared to the T2-based digi/igate that still running well after 5 years), can anyone points the possible cause that kills the board?
We scratch out lightning strike as the radio, and other radios in the shack, other computers and also the DSL modem are still working fine.
The power supply for the radio, and also for the TP-Link router, is plugged to the same power strip (to minimize ground loop).
me know what to check to prevent further problem.
Scott, any troubleshooting steps that I can try on the dead T3-Mini ?
