Just gave a presentation here at DCC on declaring a single channel on 440 as a hailing channel, then QSYing to one of the other packet channels to handle traffic like email.
I thought this might be a natural way to bridge APRS and Winlink, but was nervous about the response from APRS users about using their channel.
Imagine my surprise when I asked the audience what frequency we should use, and none other than Bob Bruninga said:
“Use the APRS Frequency, that’s what it’s there for.”
Be sure to read Bob’s comment as posted on the APRSsig.
