Thanks Joe. This whole world of Winlink is fascinating to me. In addition to the use of HF, I’m looking at the use of VHF packet repeaters in case they could be used in an emergency. I fell into a website for a device called PiGate, which acts as an email-only hotspot by connecting to a VHF Winlink repeater with a Raspberry Pi. And I can build my own, since I already have a Raspberry Pi! Very cool!
