Julian OH8STN mentioned FSQ in one of his recent blogs. He made a few comments that raised my interest in this mode so I gave it a look. The first thing I discovered is that while it does have a unique underlying data mode, it's much more of a radio networking system. FSQ incorporates clever store-and-forward facilities as well as file and image transfers.It's well worth investigating and should certainly be of interest to anyone who is involved in amateur radio emergency communications.

Over the next few days I will leave my radio station on 10.144 MHz FSQ.

Google (and Chrome) do not seem to like QSL.net but for more details of FSQ try here.
