That button will then change to RED and be labeled AUTO IS ON, and you will transmit everyĮven minute (if the TX FIRST box IS checked) or every odd minute (if the TX FIRST box IS NOT Or you can RECEIVE AND AUTOMATICALLY TRANSMIT by pressing the AUTO IS OFFīutton. You can just RECEIVE JT65 signals by pressing the MONITORīutton. 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 When you open the program, make sure you enter yourĬallsign and type your grid locator in the SETUP/OPTIONS pull down screen when you start WSJT. Just run audio from the receiver headphone jack to the LINE INPUT on the computer sound card jack,ĭownload the software, set the clock in the computer and have at it! Practice makes perfect! Please remember that it is NOT NECESSARY to have a computer interface just to practice receiving! You can often find local stations willing to practice with you, by visiting these internet pages:

K1JT has provided DEMO files on his website, so you can practiceĭecoding actual.

JT65 HF MANUAL INSTALL

“Important note: in Vista, Windows 7, and Windows 8 install WSJT to a directory such as C:\WSJT orĬ:\HamRadio\WSJT rather than the default C:\Program Files\WSJT. Use on the HF bands! Also, be sure to follow the installation instructions on the above page: Remember that, for EME, you do NOT want WSJTX or other programs that are designed for JT65A

Study the new User Manual and Tutorial (included in the WSJT download) when youĭownload the latest version of WSJT from K1JT's WSJT Home Page: 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.ĥ. Lay your radio microphone on the computer speaker (or taped up tightly against headphonesĬonnected to the computer sound output), and set the radio to transmit in VOX mode on USB.Ĥ. (or MIC IN if there is no LINE IN provided).ģ. Connect an audio line from your radio's headphone jack to your computer sound card LINE IN

Download and install the free WSJT program onto your computer.Ģ. (provided you have no amplifier and external relays to sequence on and off)! Just follow these steps:ġ. HOWEVER, even if you do NOT have any special computer interface you CAN operate digital modes I personally have had very good success with RIGblasters: PSK31 (a popular digital mode on HF) and provides for a true PTT control line (NOT VOX actuated) If you have an older radio and need an external interface, these canīe purchased from commercial vendors or you can build them yourself. Generated by the computer, although newer radios such as the Elecraft K3 have such interfaces builtin and are already "digital ready". Most stations operating digital modes use some sort of "interface"īetween the computer and radio to permit the radio to properly and automatically send the tones At Taiwan, only BV7RC/伊藤憲藏/ Kenzo Ito, and my self BX4ABD are operating JT65-HF.W7GJ'S STEP-BY-STEP SETUP TIPS FOR USING JT65 ON EME

Very popular around the world, except Taiwan.

It's a good way to study "EM wave propagation".

The hams on the air can be found at " ".

Just click a few buttons and you are done.

Noise immunity from error correction coding.

The good things about JT65-HF is as follows. Each step is just a click of button on the window. I suspect it's due to the RFI from radio, which in turn comes from unmatched antenna impedance. After I start to test the JT65-HF, my WiFi router became acting weird and hand frequent. I could have had a 600:600 transformer between sound card output and rig speaker, but I was too lazy to do so. I have a 600:600 transformer between my rig's Mic and the sound card input. In my case, I have to set up to let Ham Radio Deluxe to control the PTT, since I don't have the USB-to-UART hook-up to my rig. To start with, go to the Sourceforge page to download the freeware, JT65-HF. Many amateur radio operators have worked the world with a simple dipole antenna and 20 watts.

This is a WEAK-SIGNAL digital mode! - You should not run much power, at all.

The JT65 frequency 20 metres is 14076.0 kHz USB VFO.

The JT65 signal frequency is about 14077.3 to 14077.7 kHz.

The JT65a sync frequency is 14077.27 kHz.

JT65A is suitable for use in the 500Hz Bandwidth segments of ham radio band plans.

It was later realized that this protocol, with some adaptation, would also be very usable for terrestrial HF communications. JT65 includes error-correcting features that make it very robust, even with signals much too weak to be heard.

JT65A is actually a "sub-mode" of Joe's original JT65 protocol, which he designed to optimize EME contacts on the HF and VHF bands.
