![]() ![]() We're using fldigi for this system since we don't need features such a SSDV since we are using this simply as a tracking system once the HAB hits the ground. If you havn't found it already there's an active irc channel #highaltitude on freenode where you might find some help, and lots of tips that will help your flight a success. It's something I've been meaning to try out. (The original Pi1 wasn't powerful enough to run it). I'm not sure if anyone has tried dl-fldigi on a Pi2/Pi3 although I see no reason for it to not work. Quick point to make, fldigi and dl-fldigi are subtly different things the subtle difference being that dl-fldigi has the extensions needed for HAB (I'm assuming the fldigi above is just a typo). So I was wondering if anyone might have any suggestions for fixing this? Or if there is some sort of incompatibility between RTTY, fldigi, and the raspberry pi 3? But when it gets plugged back into the pi, fldigi on the pi cannot decode, even though all the RTTY settings are the same across the pi and my PC. When I unplug the radio from the pi and plug it into my PC, fldigi can decode everything just fine. We were getting a waterfall from the radio, the issue is that it will not decode the RTTY data coming in. So I was able to get fldigi on the pi and it seemed to be working. With this success we thought it would be cool to use a raspberry pi to perform this decoding, making the whole system more portable. We were running dl-fldigi on the laptop to do the decoding, but we also performed successful tests with fldigi. We were able to get this working and we were able to decode the data on a laptop connected to the radio with a Signalink USB. The Pi in the Sky board is broadcasting telemetry data at 434 MHz which we then receive with a Yaesu FT-817 radio. I'm working on a high altitude balloon project using a raspberry pi and a Pi in the Sky board. ![]()
