The user interface needs some convenient way of handling this situation. But if the HFDL channels are spaced close enough together to fit in the audio passband (12 or 20 kHz) of a single Kiwi channel dumphfdl should be able to handle it.

PlanePlotter can process and display Mode-S ADS-B position reports captured by the Kinetic SBS1 mode-S receiver and the associated BaseStation software or by the AirNav Systems RadarBox receiver. You can obviously run the HFDL extension on multiple Kiwi connections. PlanePlotter can decode ACARS messages, display the message content and plot any positions on a chart. Now in certain circumstances this might be applicable to the Kiwi as well. The number of channels is limited only by the power of the client hardware. It will do the digital downconversion (DDC) of those two 2300 Hz wide channels to baseband and process them in parallel. Then tell it to decode two HFDL channels, say 132 kHz. An example: You can feed dumphfdl a SoapySDR IQ connection that has a 30 MHz bandwidth centered on 15 MHz (i.e. Given sufficiently powerful client hardware, dumphfdl is capable of decoding multiple channels in parallel. The UI considerations are somewhat complicated by the following dumphfdl feature. PlanePlotter can decode ACARS messages, display the message content and plot any positions on a chart.

The HFDL code is likely to have a similar issue (if I had to guess).

It wasn't until I figured out I could rewrite it as integer code that it ran in a reasonable amount of time on the Beagle. This is completely unnoticeable on a desktop pc. Worse, the portion of the code that does signal acquisition was a huge processing bottleneck given how it was written (brute force + floating point). Should be easy to demodulate on the Beagle, right? Well, it took me a long time to figure out it was very sensitive to the quality of the sample rate conversion used. I'll give you an example: The ALE waveform is quite old and simple. For starting out, Next you need to find some acars channels and move sdr sharp, sdr uno, or sdr console to these frequencies, you will see the peaks in your sdr waterfall (around 1.545.029 is a good start), set jaero to 600bps or 1200bps at the bottom of the Jaero window to start with as these are the easiest to decode then later move on to. That's much more difficult, although having existing mapping in the TDoA extension makes this a bit easier (the mapping framework is there at least). You'll want some sort of mapping like all the desktop packages have. Using PlanePlotter, you can see a radar-like display of all those aircraft around you that are transmitting the appropriate digital messages including ACARS, ADS-B and HFDL. I have been able to decode transmissions on 130.450, 131.125, and 131.475. PlanePlotter - PlanePlotter is a windows decoder of live digital position reports from aircraft and plots them on a chart. I have noticed in my area (35 miles west of DFW airport) there are a number of frequencies used.

The next problem is that you guys won't be happy just seeing screens full of ACARS messages. I have been able to decode some ACARS signals using SDR and acarsd. I'd have to analyze the waveform demodulation code and try and gauge how intensive it is in terms of Beagle compute resources.
