[aprssig] OT: Yaesu to release digital amateur radio gear

[Eric Hansen]

Well the data it transmits over the air has to be an open,
unencrypted, stream. Otherwise it would run afoul of a basic tenet of
Amateur Radio. I don't think you could be prosecuted for building a
device or writing software that decodes data sent out OTA. But, IANAL.
