First review of the Mobilinkd TNC3 for APRS on a budget

In this video I give my first impression of the TNC3 APRS and packet device (terminal node controller). The aim was to see if the improvements with the version 3 compared to 2 means that the hardware is more compatible with budget radios as well as connecting up to iOS devices.

I was impressed with the ease in which the device worked with my Baofeng GT3TP and it pulled weak APRS packets out of the RF.

I have not tested the battery life yet which is stated in the specifications as lasting up to two days receive only.

APRS is a very powerful mode for amateur radio operators, not only for the tracking features but also for communication purposes. The ability to send messages and data via VHF and HF is a key feature in emergency communications which should appeal to emcomm operators and those who prepare for SHTF and grid down situations.
