WoAD
Bringing the functionality of Winlink to your Android device
The use of WoAD requires a valid amateur radio license. Do not use, install, or download WoAD unless you have a valid amateur radio license, or a license from a participating government service or agency. Ship station, marine or general radiotelephone licenses do not qualify.
WoAD can be used as a client of the Winlink Global Radio EmailⓇ system or for direct connection to a peer-to-peer (P2P) capable client, via either the internet or a VHF/UHF AX.25 packet connection.
