Keep in mind WSJT-X Software Release Candidates may still have bugs so be prepared to report those if they come up. While it’s not known what the ETA is on getting FT8 added, it will be published on the Internet. Packages for Windows, Linux, OS X, and Raspbian Jessie and be downloaded from the WSJT web site at:īe aware: this mode is very new – as of, both eQSL, LoTW and QRZ are not accepting FT8 as a valid mode – they are aware of the new mode and proper notification has been dispatched to those who run those sites. To get started with this new mode (FT8) you can grab the installation packages for WSJT-X Version 1.8 or better. We look forward to receiving your feedback.Ī short list of new features and capabilities (including the new FT8 and FreqCal modes) can be found in the Release Notes for WSJT-X: Suggestions for FT8 setup and examples of use can be found in a screen Your results to us! Pre-built installation packages will be madeĪvailable after further testing is completed. Revision r7750 or later, and would like to help, please do so and report We’re now at a stage where tests under a wider range K1JT, K9AN, and G4WJS have conducted on-the-air tests of FT8 withĮxcellent results. Your considered suggestions for use of these We have in mind special message formats that might be used Three extra bits are available in the message payload, with uses yet toīe defined. Information as it accumulates during a QSO. Subtraction, two-pass decoding, and use of “a priori” (already known) *Still to come, not yet implemented:* We plan to implement signal
#JT65 MODULATION FULL#
Offers multi-decoding over the full displayed passband. Sensitive, has much smaller bandwidth, uses the vertical waterfall, and *Comparison with fast modes JT9E-H:* FT8 is significantly more Greater than JT9, but about 1/4 of JT65A and less than 1/2 QRA64. Sensitive but allows completion of QSOs four times faster. *Comparison with slow modes JT9, JT65, QRA64:* FT8 is a few dB less
#JT65 MODULATION MANUAL#
– Auto-sequencing after manual start of QSO – Multi-decoder: finds and decodes all FT8 signals in passband – Operational behavior: similar to HF usage of JT9, JT65 – Decoding threshold: -20 dB (perhaps -24 dB with AP decoding, TBD) – Synchronization: three 7×7 Costas arrays (start, middle, end of Tx) – Waveform: Continuous phase, constant envelope – Modulation: 8-FSK, keying rate = tone spacing = 5.86 Hz They are calling the mode “FT8” (Franke-Taylor design, 8-FSK modulation)įT8 is designed for situations like multi-hop Es where signals may be weak and fading, openings may be short, and you want fast completion of reliable, confirmable QSOs. Steve(K9AN) and Joe(K1JT) have developed a potential new mode for WSJT-X.
