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. For the past 12 months or so after reading about the exploits of Dave Akerman and his first launching of a Raspberry Pi into near space I've been tinkering with the idea of launching a balloon myself.I'm working on a high altitude balloon project using a raspberry pi and a Pi in the Sky board. Although there isn't a huge HAB community in NZ there have been some previous launches, and there is plenty of good information and useful tools available via the UK HAS web site, and #highaltitude IRC channel. The IRC channel in particular has been a great source of information with many friendly people willing to share their experience and knowledge. It's also been very interesting tracking and watching launches live. Even from the other side of the globe it's sometimes possible to watch live video streams of flight preparations at the launch site and from the chase cars as they track balloons across the country-side. When video isn't available it's still possible to track progress via the live updates on the tracking site and running commentary on #highaltitude. Slowly different aspects of the project have been coming together. Most recently I reached my first major milestone, successfully transmitting and decoding telemetry. I've decided to blog about my exprience with this so far as it may be useful or interesting to others wanting to do something similar. Starting from the payload end and working through to the receiving and decoding end my setup looks like this: I'm planning on using a Raspberry Pi Model A for the payload although for development I'm using a Model B as I have a couple of these already on hand purchased from Element 14. As my day job is J2EE development, Java was my preferred choice of language for the payload control software.
