SERIOUS ERROR - Uncaught and thrown from GUI ... device.rtl.E4KTunerController cannot be cast to class device.rtl.R820TTunerController

[denzs]

I am trying to run Foxtelem with an RTLsdr (Nooelec with E4000) on Debian unstable. RTLsdr is working fine with gqrx.

When trying to start the decoder in Foxtelem an error message with the error below appears and nothing happens. When starting without the wrapper the output is:

Am i missing something? If this is a bug let me know how i can help debugging!

Definitely a bug. Will try to look at it soon though I do not have that type of tuner.

Thx fo replying! :) If i can help with testing patches or anything else, just let me know!

[ac2cz]

The RTLPanel.java class assumes the device is an R820T. I need to code a new panel for the E4K tuner, which has a different API.

[ac2cz]

I've refactored the class that was complaining about the E4000 dongle. You can run the test version 1.10c from here: https://www.g0kla.com/foxtelem/downloads/test/

I don't have a dongle to test with, so it may well crash. Report back here.

[denzs]

The issue still exists...

I double checked, that i am running 1.10c :)

[denzs]

I just realized, the stack trace is different in the current version :) full log here: foxtelem.log

[ac2cz]

Thanks for testing. That is progress because the error is in the new RTLPanelE4K that I created. I'll make another build for you to test that tries to fix that.

[denzs]

Thank you so much - I really appreciate what you are doing! :) Let me know if i can help with testing or anything else..

[ac2cz]

You can test version 1.10c2, which is here: https://www.g0kla.com/foxtelem/downloads/test/ You don't need the whole release unless that is easier for you. You can just grab the FoxTelem.jar file that is in that folder and patch the test version you installed. Just replace the jar file.

Let me know if it works or what the next error is. Many thanks!

[denzs]

This looks very promising :)

While starting up this message appears:

After confirming the dialog it seems to be working!

Here is the full log: FoxTelem_working.log

As i have no experience with running FoxTelem til now, i cant really say if everything is working. But this already looks really promising, i will mount my antenna, play with it and let you know if i find something interessing :)

[denzs]

The message from above shows up every time the decoder starts running.

Til now i was not able to decode a single frame, but i think this is due to my very simple antenna (without filters or lna). I will improve my setup and let you know when i decoded something or when i find further issues..

[ac2cz]

I have update this to fix the issue where it won't set the frequency. It is again here: https://www.g0kla.com/foxtelem/downloads/test/ And again you don't need the whole release unless that is easier for you. You can just grab the FoxTelem.jar file that is in that folder and patch the test version you installed. Just replace the jar file.

[denzs]

I can confirm that the messagebox is gone with 1.10c3 :+1:

I've used my Arrow 146/437 in combination with an FM filter and LNA and et voila: https://www.amsat.org/tlm/ground_station.php?id=0&db=FOXDB&station=DL3SD

So from my point of view this can be closed and rtlsdr@E4000 can be added to the list of supported devices.. Thank you Chris! :)

This is working, but this crash seen on windows 10:
