2020-12-31 The igate is still receiving packets and slowly building coverage
Since the igate build was finished and the first packets were received I left it running. I did switch to a 5 volt power supply: it works fine on a USB charger powering the whole circuit board via the USB connector for the ESP32. Packets are received from a large area around the city as shown. I'm glad it is all working and I hope to improve the APRS network coverage here locally a bit.
