Over the past few weeks I’ve worked to improve operating with WSJT-X. Everything from improving the wide graph (waterfall), logging to HRDLogbook, setting up alerts and improving the Icom 7300 settings. All of it plays a role in WSJT-X and making JT65/JT9 more enjoyable.
The Icom 7300 Settings
Inside the rigs menu things are pretty much the same. If you look at my previous videos I believe I have lowered my USB MOD Level some and my ACC/USB AF Output Level, but that’s all. The other settings are the same. I run two cables. The CI-V cable for rig control and the USB cable for data modes and keying.
It’s possible to use one USB cable and a virtual serial port emulator to get keying and the use of FSK and CW keying, but I’ve chosen two cables. I used virtual serial ports with my Flex 1500 and it works, but using two cables seems easier to me.
Important operating settings: NB is turned off, NR is turned off, AGC is turned off, RF Gain down, and FIL1 is set to to 3.6k. Mode is USB-D.
One more important point. This is the easiest way I’ve found to monitor and adjust the power output in digital modes is to set the radio for 100% RF POWER and use the level slider in the software. See: Icom 7300 Controlling Power Output Digital Modes
