Wfview Log4OM and WSJT-X with GridTracker for a Super Combo

Want to run Wfview Log4OM and WSJT-X? There are many ham radio software options out there. But, when it comes to logging and decoding FT8 signals, Log4OM and WSJT-X are very popular. Adding Wfview and Gridtracker to the software combo makes it even better.

For this article, I will be focusing on FT8 decoding and FT8 logging using GridTracker as the conduit to Log4OM.

Wfview and Log4OM

I have been using this combo for quite a while just for general logging. Then I added WSJT-X and Gridtracker because I like the GT map and it will help me log my QSO's right into Log4OM without any complicated settings in Log4OM. I'll show you how.

Please see my previous article for how to use Wfview and Log4OM: Checkout How Wfview and Log4OM Work Together

WSJT-X and Wfview Used For Rig Control

This is very easy to do. Just make sure in Wfview you have the Settings correct under External Control. You will want Enable Rigctrld and the port 4532 set. See screen capture below.

WSJT-X Settings

This is easy too. We want Wfview to control the radio, but also WSJT-X to have control too. I like to use the drop down list of frequencies in WSJT-X. So, under Radio tab, we need Hamlib NET rigctl for the Rig and we need the correct port set. That will be Let's not forget the Audio tab with Soundcard settings and the Reporting tab. We want port 2237 for UDP requests set. See screen captures below.

GridTracker Does the Logging to Log4OM

So there's no need to add any complicated settings to Log4OM for logging if we use GridTracker. WSJT-X with it's UDP enabled, will be able to communicate with GridTracker and GridTracker will send QSO’s to Log4OM.

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

Great write up on a great combination. Only tip I would give is that if you have an IC-7610 like I have (using the same software combination), Wfview can handle the CAT and audio connection to it through the Network port. Eliminates the need for VSPE although you still need VAC. At least in my case, eliminating the need for USB cables for CAT/Audio connections led to a much quieter noise level. Keep the content coming Rich !

Rich –

All of the WSJT, WSPR, etc. links appear to be broken. I found the most recent WSJT-X download on SourceForge –

Maybe it’s on my end, but I got nothing but 404 errors from Princeton. Maybe Joe doesn’t host them there anymore ?

I configured Wfview, Log4OM, WSJT-X, and GridTracker as prescribed. However, Wfview will not control the radio because the COM channel is busy (selected Hamlib, although I do not know what that is). When I switch back to Omni Rig 1 from a previous video it works standalone, but not with WSJT-X, Log4OM, and GridTracker running simultaneously.

Set up OK until I reach wsjt-x. wsjt-x settings/Rig/Omni-rig ctl 1. Test CAT which gives error: Omni Rig Port Not Available. What might I have mis-set?
