An auto-sequencing facility includes an option to respond automatically to the first decoded reply to your CQ.įT8 QSOs are 4 times faster than those made with JT65 or JT9. FT8 uses 15-second T/R sequences, provides 50% or better decoding probability down to -20 dB on an AWGN channel, and maintains good performance on Doppler-spread fading channels. The mode name “FT8” stands for “Franke and Taylor, 8-FSK modulation”. WSJT-X Version 1.8.0 includes a new mode called FT8, developed by K9ANĪnd K1JT. So what is FT8? Taken straight from the release notes of the new software: Many, many, many JT65 and JT9 qsos, were lost due to the E skip allowing for the start of the qso, but faded out before the qso was complete. Or, you could get the right conditions and work stations for hours – it all depending on how the E cloud was working for you. Be strong for 2 minutes and then gone for days. For anyone who has spent time on VHF such as 6 meters, you know that Sporadic E’s can come and go in waves. On VHF, especially 6 meters, it was a new tool to try to work new stations that otherwise you could not detect – however, there was one major issue, the time it takes to complete a qso. On HF, it provides for a very casual operating speed. ![]() The fastest most qsos would be completed was 4 min. ![]() 48 seconds of transmit, followed by a 12 second decode window, followed by 48 seconds of receive, followed by a 12 second decode window. #JT65 HF YOUTUBE SOFTWARE#One of the issues that was present in the JT software is the long transmit and receive cycles. The advent of this technology and software has allowed for the explosion of smaller EME station to get on the air and start working folks, where before, their signal strength was not loud enough to be heard by your ears. As in pulling out stations that are -20 db into the noise weak signal. If you are familiar with JT65 or JT9, you know that these are weak signal digital modes. 73 from Joe, K1JT, for the WSJT Development Group For both lists you will need to be a subscriber in order to post there. Please report any problems you find with this beta release to one of these email lists. There is no need to uninstall a previous version or to move any files. Upgrading from version 1.4 or later will be seamless. Installation packages for Windows, Linux, OS X, and Raspbian Jessie canĪ detailed log of program changes since v1.7.0 is available here: A short list of new features and capabilities (including the new FT8 and FreqCal modes) can be found in the Release Notes:Īfter any reported problems with this beta release have been addressed, Version 1.8.0 will become the standard “General Availability” release of WSJT-X. This is a beta release, already tested in the field by around 160 alpha-test users. The WSJT Development Group is pleased to announce a candidate release of WSJT-X Version 1.8.0. On July 11th, the world was introduced to the public beta of the WSJT-X software version 1.8 which included the release of the new mode: FT8. ![]()
