Hi Jamey,
Looking at this some more, I think the problem is that you need to make a COM port associated with your USB connection between the RPi and your radio. I don’t think that WSJT-X can directly talk to a USB port.
Hi Jamey,
How did you physically connect the RPi to you KX3? What sort of cable did you use and how does it connect to the radio? Does the RPi SW give you any other choices for the serial port?
Hi Jamey,
Can you tell what sound card ports that WSJT-X is using on the Pi side? That would be a place to start. Not sure how to handle PPT on the KX2 side – maybe via VOX?

LEO Pack Satellite Antennas[/caption]Hello Harry,
Sounds like an interesting project! A couple of initial thoughts. First, it will be critical that the top of the mast where the rotator is mounted is solid and completely stable. This is achievable if the mast is secured to the building very near the top where the rotator will go. Satellite signals will not penetrate buildings very well so you’ll want the top of the mast to be a little above the roof plane on the building.
I think that the Yaesu rotator is a little light for this sort of mounting and I’d recommend that you take a look at the Alfa-Spid Az/El instead. It’s designed to be mounted on a mast and its housing is not prone to breakage which can be the case with the Yaesu.
The LEO pack is a great choice for use with satellites. You can get a discount on these antennas if you join AMSAT. More on AMSAT here.
You’ll want to use computer control for a setup like this. You can read a series of articles on how to do this starting here.
Our Field Day 2019 satellite station will be using a LEO pack antenna system. If you are coming out to Field Day, I can spend some time with you to operate satellites then.
I’d be happy to spend some time with you to talk about satellite station building and operating. See me at a meeting or email me at [email protected].
Good luck with your project!

HAB Camera Insulation and Heating System[/caption]We build a simple insulation system which included small hand warmers. Here’s a link to an article the give some details.
I wanted to update everyone on the final outcome of HAB-4’s flight.
Our HAB landed west of Worcester at about 1:35 pm this afternoon. We located it quickly but it was about 60 ft up in a large tree. It took Curtis quite a while to get it out of the tree. Our HAB was in good shape with no damage.
Our camera insulation system helped! Our “lucky looking up” camera stayed on for a good portion of the flight. Check out the following link in the post above for some amazing video.
The looking out camera shut off early again so we have some more work to do there. We captured some good video of the launch and the first 45,000 ft of the flight. More to come there.
Based upon the pressure and temperature telemetry data, we are estimating that our HAB burst at about 115,000 ft. We found that the HAB’s computer, GPS, and APRS transmitter were fine after we reset the flight computer when we got the HAB back. We have some more detective work to do but we will most likely replace the computer and the GPS for the next flight. All in all, HAB-4 was a successful flight and we have learned a good bit.
We’ll clean up the data and do some work on a nice video after Field Day and we’ll certainly share all of this will you in the coming weeks.
Thank you to everyone who helped make HAB-4 and amazing experience and a special thanks to Curtis for scaling the 60 ft tree to get our HAB back!
