Re: Index Error: output_index < noutputs

[Jeff Long]

I replaced the Transmit_CESSB block with a Noise Source and Throttle to make a valid flowgraph. Did you mean to send freq.grc instead of freq.py? Disabled that block in the top level flowgraph. In any case, no errors when running the flowgraph. When I hit PTT, I see noise, and otherwise nothing (no audio being played). The wave_select code seems to be right. It's set to a static "0" at the top level and that carries through to the hier block.

This is on the latest maint-3.10 code. I don't have a 3.9 installation sitting around. There was a recent behavior change in this block, but nothing that should cause the error message you are seeing.

I did replace the Wav File Sink blocks in FT8 Receive with Null Sinks for testing, so you might want to do that just to check.

Jeff,

 

I have attached the top level GRC (softrock_QT.grc), the Receive.grc hier block (feeds the stream to the FT8_Receive block) and freq.py (the OOT module containing the code that I am questioning).

 

The Transmit hier block is not pertinent to this discussion.

 

Note that this is a fully functioning SSB transceiver that I have had on the air. I am attempting to add the digital mode FT8 to it using the FT8_Receive block along with some additional code in the freq.py file.

Sorry, it takes too much time to make guesses from fragments of a project. Could you post a grc file that is runnable and shows the error?

Marcus,

I forgot to include the version: 3.9.4.0.

Ignore the previous GRC with the Python block. I did things differently this
time as you can see in the connections. I also attached the FT8_Receive.grc
file.

Hi Jim,

since we've worked on Selector recently, it would **really** be important to
know the
version of GNU Radio you're dealing with!

Best regards,
Marcus
