@benb0jangles well, that settles it.
The Airspy cannot do 1MSPS. The Mini can do only 3MSPS and 6MSPS, and the R2 2.5MSPS and 10MSPS. Every other samplerate will not work and cause this kind of issues!

That's definitely not supposed to happen.
Do you have a screenshot? Could you perhaps provide some baseband? (Since on my end, it does seem to lock fine)
Thanks

Sorry for the late answer. I've had similar reports that lead to this fix a92e595, which I think also affected LRPT as it pretty much always go through the resampler...

That is definitely not the same issue, the BPSK demod locked just fine.
Could you perhaps try recording baseband and seeing if that works?
Also, are you running the latest APK from Github CI?

@Aang23 I am noticing also during my build stage:
cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_LIVE=ON -DCMAKE_INSTALL_PREFIX=/usr ..
Volk message:
Performing Test VOLK_HAS_volk_32fc_x2_add_32fc - Failed
But still compiles
So perhaps I will try to build Volk from source and see what happens. Do I need to place volk_config into satdump directory or no?
At the moment my sytem has volk:
volk-config-info --version
1.3
My Jetson Nano device is Arm A57 but I do not see anything in:
volk/cmake/Toolchains/
for the Jetson ARM A57 CPU
ugh, when compiling volk:
make test
0% tests passed, 139 tests failed out of 139

commented on June 4, 2024
About this error when building, that is expected if you are running Volk <=1.3. I do this test to provide a fallback implementation if Volk does not provide it.
Failing or passing doesn't really matter at all, some (unused) code would just be a bit slower.
No, volk_config should be left where it is.
That's weird when compiling Volk though... May be an ARM-specific issue, but I'd advise opening up an issue in Volk. Not a SatDump issue by any means.

Differences in the Log between Jetson Nano & Macbook are Macbook has Volk Spiral, perhaps because has volk version 2.4

@Aang23 as an update:
Today I recorded the .s file for a Meteor-M2 pass using SDR++ and SDR++ Meteor Demodulator.
Offline Processing this file using satdump works and I have satellite image as expected.
So perhaps the satdump live processing demodulator is not successful just yet?

@benb0jangles sorry for the late answer.
It's possible something is going wrong in the demodulator, but others and I have been unable to reproduce the issue. Are you able to provide a baseband sample? Really the only way I may be able to figure it out with this kind of issue.

@Aang23 I have recorded baseband using satdump + these settings:

Frequency: 137.1Mhz

Format: i16
The .i16 file is over 3GB in size so I must wait a couple of hours before I can complete the upload to gdrive
Here are screen recordings during baseband recording

So I guess I will try LRPT with 3MSPS on Airspy

commented on June 4, 2024
LRPT works very well on the Airspy-R2 at the 2.5M sample rate & should do well on the Mini at 3M. If the computer can handle the higher sample rates for those devices, 10M or 6M will work great, too!

commented on June 4, 2024
@Aang23 so this morning i tried LRPT using 3M with aIrspy mini and result is improvement. The demodulator is now functioning and SYNC is acheived.
Signal is not as strong as using SDR# or GQRX or similar software, but I think still capable. For this morning pass I had to contend with NOAA15 and POCSAG interference. I use a 137mhz Bandpass filter, but I think I will remove it tomorrow because the filter lowers the db by 30%. I am hoping stronger signal will create better image, this mornings image was terrible but it was the first one using Satdump live so also success :)
export2.mp4
I like that it is working on 5v Jetson Nano 2GB it is amazing now to think that full live LRPT - Signal - Demodulation - Decoding - Processing is functional on cheap ARM device.
My future goals will of course to push and see if it can also do Live HRPT at 6M once I finish making my DIY parabolic antenna, and the rain stops. Tomorrow I expect result to be much better.
Good luck with development, I think you have powerful software in Satdump, can I suggest future goal of having satdump as a plugin for SDR++?
-SDR++ for signal + Output to Satdump Live processing
-Satdump using SDR++ Output for Demod, Decode, Process
I say because I think SDR++ will have cleaner signal, better RF options.
