New Version of WSJT-X July 2021

/

A new version of WSJT-X, the software suite that includes FT8 and other digital protocols, has introduced a new mode, Q 65.

According to the release notes, it is designed to accommodate fast-fading signals and paths with Doppler shifts of more than a few Hertz.

"Q65 is particularly effective," the notes say, "for tropospheric scatter, rain scatter, ionospheric scatter, TEP (trans-equatorial propagation) and EME (Earth-Moon-Earth) on VHF and higher bands." It uses the same message formats and sequencing as those used in FST4, FT4, FT8 and MSK144.

Q65 is one of 11 total modes included in the latest WSJT-X package.

RFzero Now with FST4W

/

A new version of the RFzero library has been released. It includes the new FST4W narrow digital mode with its four sub-modes. This enables the RFzero GPS controlled RF source to send FST4W as a stand-alone transmitter.

The RFzero is a multi-purpose GPS controlled RF unit. It can be used as a beacon (IBP, SPB, CW, FST4W, FT4, FT8, JS8, JT9, PI4, WSPR, …), signal generator, VFO, QO-100 dual LO, low-cost GPSDO, e.g. for 10 MHz or 49,152 MHz for the IC-9700, or … Furthermore, is the RFzero an Arduino compatible platform. So it is possible for you to write or modify the software yourself.

More than 20 programs, Arduino sketches, are integrated into the Arduino IDE for easy upload to the RFzero.
