That button will then change to RED and be labeled AUTO IS ON, and you will transmit every even minute (if the TX FIRST box IS checked) or every odd minute (if the TX FIRST box IS NOT checked). Or you can RECEIVE AND AUTOMATICALLY TRANSMIT by pressing the AUTO IS OFF button. You can just RECEIVE JT65 signals by pressing the MONITOR button. JT65B is used on 2m, and JT65A mode is the worldwide standard for 6m EME. You also must the MODE tab at the top of the screen to select the correct JT65 mode. When you open the program, make sure you enter your callsign and type your grid locator in the SETUP/OPTIONS pull down screen when you start WSJT.
#JT65 HF DOCUMENTATION HOW TO#
The secret to success in learning how to efficiently and accurately use the JT65 software to decode weak signals is PRACTICE, PRACTICE, PRACTICE! You can often find local stations willing to practice with you, by visiting these internet pages: ON4KST EME CHAT (used for 6m EME): N0UK TERRESTRIAL JT65A CHAT: Please remember that it is NOT NECESSARY to have a computer interface just to practice receiving! Just run audio from the receiver headphone jack to the LINE INPUT on the computer sound card jack, download the software, set the clock in the computer and have at it! Practice makes perfect! K1JT has provided DEMO files on his website, so you can practice decoding actual. (Otherwise, you might need to set some read/write permissions explicitly.) * DEMO AND PRACTICE.
#JT65 HF DOCUMENTATION INSTALL#
Study the new User Manual and Tutorial (included in the WSJT download) when you download the latest version of WSJT from K1JT's WSJT Home Page: Remember that, for EME, you do NOT want JT65 from other programs that are designed for use on the HF bands! Also, be sure to follow the installation instructions on the above page: Important note: in Vista, Windows 7, and Windows 8 install WSJT to a directory such as C:\WSJT or C:\HamRadio\WSJT rather than the default C:\Program Files\WSJT. Follow the steps on this page to properly choose the settings for JT65 mode when you run WSJT. Set your computer clock accurately to UTC. Lay your radio microphone on the computer speaker (or taped up tightly against headphones connected to the computer sound output), and set the radio to transmit in VOX mode on USB. Connect an audio line from your radio's headphone jack to your computer sound card LINE IN (or MIC IN if there is no LINE IN provided).

Download and install the free WSJT program onto your computer. I personally have had very good success with RIGblasters: HOWEVER, even if you do NOT have any special computer interface you CAN operate digital modes (provided you have no amplifier and external relays to sequence on and off)! Just follow these steps: 1. Anything that will permit PSK31 (a popular digital mode on HF) and provides for a true PTT control line (NOT VOX actuated) will probably work fine for JT65. If you have an older radio and need an external interface, these can be purchased from commercial vendors or you can build them yourself. Most stations operating digital modes use some sort of "interface" between the computer and radio to permit the radio to properly and automatically send the tones generated by the computer, although newer radios such as the Elecraft K3 have such interfaces built-in and are already "digital ready". USING JT65 FROM WSJT10 (jump to for WSJT-X) Although this mode used to be more common for EME on VHF, it has come to HF like files to a outdoor barbecue! It is especially popular on 20 and 40 meters.W7GJ'S STEP-BY-STEP SETUP TIPS FOR USING JT65 ON EME (Revised 7 June, 2017)Ī. I also made a JT65 QSO with 2E0TEC, Carl in England. My first QSO was with station PY9FP, Francisco in Brazil.
If you want to find out more about it there are some great videos on YouTube that will help you learn how to configure the software and use JT65-HF. I am only using 5 watts for my JT65 QSOs and some would say that is still too much power! Most of the time QSOs are made with between 1-10 watts of RF power.
The interesting part however, is that this mode can be used with very low power. There is not a lot of action with this mode and QSOs can take a long time because it takes a while to exchange the messages with other stations. Today I spent a little time playing with a mode that I have not had much experience with: JT65.
