I don’t know if anyone is already using the Pico APRS for SOTA spotting:
For those who happen to own one, you may be interested to know that I just managed to finally get my Pico APRS sending messages to the APRS2SOTA gateway:
The developer has updated the firmware especially to include punctuation signs like / and - in the message text, which is essential (as far as I know) for acceptance by the gateway. As can be seen, the unit is very minimal and lightweight. It has a maximum TX of 1W, so not as much as an HT, but for those using a lightweight beam for 2m, it should still be enough to get spotted. It can also be connected to an Android device and used as a KISS TNC; something else I am gradually getting my head around.
