Jt65 hf documentation
The next 47 seconds your radio is in transmit sending the report. You have 13 seconds to see it and either double click the acknowledgement or click on Send Report. Assuming the CQing station picks up your call, he has ~13 seconds to initiate the action which QSLs it from his end.

Your radio is transmitting for the full 47 seconds.
You double click on their CQ in the list before it hits the top of the minute and the program sends your call back to them for 47 seconds. A JT65 cycle occurs as follows:ġ) On the top of each minute 47 second transmission occur.Ģ) There is a pause for 13 seconds which allows everyone to select their next actionĪ typical QSO is a station sends CQ and at 47 secs after each minute you can see what stations are calling. Using JT65-HF is essentially point-and-click. I watched a couple quick YouTube videos to get the idea and I was off and running.
I did reduce the audio gain on the main screen until the signals were the only noticeable output on the waterfall. I have a SignaLink USB and just needed to select the SignaLink in the drop-downs for input and output devices. Configuration involved just specifying my call, grid square, soundcard input.output and PTT port. Installation and configuration was very straightforward for me.

I would suggest the free NetTime program at which installs as a Windows service. “We will be working on that in the near future.”Ī new Facebook group has been established for FT8 experimenters.You need to have accurate time and need a time check/sync program that is more frequent than one built into Windows. “We know that the advent of new mode FT8 means that new material is needed for the User Guide,” Taylor told the Yahoo Meteor Scatter and Weak Signal Group this week. Operational documentation for FT8 has not yet been finalized. A new TQSL configuration will be released once the new mode has been accepted to ADIF, which could happen within a week. Configuring TQSL to automatically map FT8 contacts to “DATA” will enable users to upload FT8 contacts now, and confirmations will be valid for DXCC Digital, VUCC, WAS Digital, and WPX Digital awards. Because FT8 is still in beta, it has not yet been added to the ADIF tables. Some of the 22 QSOs may have been difficult to complete on CW.”Įnthusiasts will have to wait a little longer for Logbook of The World ( LoTW) to accept FT8 contacts as FT8 contacts.

In a limited outing for the CQ VHF, Frank Donovan, W3LPL, made 22 FT8 contacts on 6 meters, “during which the FT8 software reported SNRs from my receiver below –10 dB (measured in a 2,500-Hz bandwidth). The beta release came out just days before the July CQ VHF Contest and proved to be a boon to many operators who took advantage of FT8 on 6 meters. “FT8 is an excellent mode for HF DXing and for situations like multi-hop Es on 6 meters, where deep QSB may make fast and reliable completion of QSOs desirable,” Taylor’s release notes assert. An auto-sequencing feature offers the option to respond automatically to the first decoded reply to your CQ. Like JT65, FT8 requires accurate time synchronization. Unlike JT65 or JT9, transmit and receive cycles in FT8 each last about 15 seconds. Tones are spaced at 6.25 Hz, and an FT8 signal occupies just 50 Hz. The numeral designates the mode’s 8-frequency shift keying format. The new mode is named after its developers, Steven Franke, K9AN, and Joe Taylor, K1JT.
The notes for the “candidate” release say that FT8 offers “sensitivity down to –20 dB on the AWGN channel.” Contacts are four times faster than with JT65 or JT9, and an entire FT8 contact can take place in about 1 minute. Among its biggest advantages is a shorter transmit-receive cycle, meaning quicker contacts. FT8 is included in a beta release of WSJT-X, version 1.8.0-rc1. It’s still in beta testing, but FT8 - the latest digital bauble to capture the imagination of the Amateur Radio community - has been luring away many of those already using the popular JT65 “weak-signal” mode.
