Description

The new WSPRSONDEs are now available!  This eight-channel FST4W and WSPR transmitter puts out 1W simultaneously on each channel, with microHz-level frequency accuracy and stability (external 10 MHz reference clock required).

The square-wave outputs can operate from 1 to 60 MHz (generally on the ham bands), and require harmonic filtering for legal operation.  Typically this filtering is provided by either the Turn Island Systems 6-Band or the 9-Band Filter-Combiner, which allows the use of a single multiband antenna.  Single-band filters are also available.

For more details please review the WSPRSONDE Quick-Start document.
