Right. The WSPR receive window is a couple of hundred hz wide. Your freq
doesn't have to be accurate, but your clock should be within a second of the
right time.

BTW, you can use WSPR to calibrate your rx and measure freq within a hz or
so; Dr. Taylor's instructions are in the latest documentation.

The various JT modes and the ideas behind them are a massive contribution to
amateur radio. It's cool to share your hobby with Nobel winners.
