When you change modes it seems to be fairly immediate, ive just finished putting one of these together and when I change mode inseams to be rebooting. in addition I can only get FSK mode toward reliably. Any clue why this might be?
Hi Devlin, I’d need to see your logs to be sure. It should not reboot each time you change modes. If you share some logs (the output of CubeSatSim/log command on the Pi) on the GitHub Discussion page we can troubleshoot it: github.com/alanbjohnston/CubeSatSim/discussions
Hello, i´m testing this setup with the CubeSatSim Lite, using only the raspberry pi and an antenna, but it isn´t working. I´m successfully receiving the transmission of both cw and asfk files in SDR# at 107.5MHz, but my raspberry is not transmitting like yours at fixed intervals and getting quiet between transmissions, in my case the signal is high even whe not transmitting data, and i can´t get any telemetry data in the ASFK1200 decoder using the virtual cable and neither i´m able to get data on Fox Telem using the SDR directly. Do you have any suggestions on how i can solve this issue?
Hi Danilo, you are using the original CubeSatSim Lite. It transmits an AFSK recording in the FM band. If you can hear it at 107.5 MHz, then it is working. You will get a strong carrier signal between AFSK packets - that is normal. It should be possible to decode it using AFSK 1200 Decoder. Make sure the audio levels are high enough and the virtual cable is selected correctly. This version of the CubeSatSim Lite does not do Fox emulation, so you won't be able to decode anything using FoxTelem. However, if you build a Transmitter/Filter Board (github.com/alanbjohnston/CubeSatSim/wiki/New-Transmitter-Filter-Board-Hardware-and-rpitx-Software-Install) then you can run the latest CubeSatSim software (github.com/alanbjohnston/CubeSatSim/wiki/2.-Software-Install) This will work with FoxTelem and will even generate simulated telemetry for you to look at. Good luck!
This is great, thanks.
Glad you liked it!
