Have you heard of JTDX? It’s similar to WSJT-X and will operate FT8 if you download and use the evaluation version, JTDX v2.0.1-rc135 (as of this writing). So why JTDX? A number of fellow Hams have suggested I do a video on this. Many say it is better at decoding than WSJT-X. I have been using it with the Icom 7610. If you are using the Icom 7300, it is virtually the same setup.
Icom 7610 Settings
Have a look at my Icom 7610 screen captures page. The 7610 is in USB-D1 mode for digital operation. I have the filter BW at 3.6k, noise blanker off, noise reduction off and AGC set to fast. I have found I like AGC set to fast. Turning AGC off is good too, especially for JT65 and JT9.
JTDX Download and Install
You can download and install JTDX from this link. I have installed version JTDX v2.0.1-rc135 because I want to use FT8. It appears to be working just fine for me and I like some of the features it has over WSJT-X. See the video below.
It’s a simple installation, similar to WSJT-X.
I have some screen captures below. In the Icom 7610 and Icom 7300 I have left all of the internal radio settings the same.
While operating, one thing to be aware of is the RX level. Try to keep it between 30dB and 50dB. I show how to set this in the video below.
The Pwr level slider is the same as the one in WSJT-X. I use it to set the ALC on my Icom radios. I have an article and video showing how I set my power level for digital modes. See: Icom 7300/7610 Adjusting RF Power Digital Modes
I use it to log into HRD Logbook, but I also use it to pull the name and QTH from QRZ.com.
