Allow bias-tee config on initial setup or another config file

[cocus]

Hi! Another fellow Argentinean here. I'm using this code, which works pretty well, but I had to modify it in order to use the bias tee, since I have the SAWbird+ NOAA which requires it to work. I know the change is pretty much straightforward on the receive.sh script, but maybe that could be an option to be asked on install-time. Even a simple parameter on the ~/.noaa.conf could be used to determine this. An appropriate bias-tee enabler argument is: -T (or at least, that worked for me)

Hi Santi! Sure thing, I'll wrap that at install time so you don't need to dig into the files to enable it.

I have tried to install again, but no bias-tee possibilities.

[reynico]

Hi! Have you checked out the branch enable_biastee before running install.sh?

[tomamdy]

Which branch do You advice ?

[cocus]

I tried his new branch enable_biastee which is the one from the PR #19

[tomamdy]

But it doesn't worked for me.

[reynico]

uhm, you may need to either delete the ~/.noaa.conf file to copy the new template or run the next command to add the required line

echo "BIAS_TEE=\"-T\"" >> ~/.noaa.conf

[tomamdy]

Sorry, but nothing. I really don't understand this.

[cocus]

Which hardware do you have? Please run a cat ~/.noaa.conf and copy the output. Also do a cat ~/raspberry-noaa/receive.sh just to check if you got the changes.

For some reason, your receive.sh is not up to date to the branch we've mentioned. Try this cd ~/raspberry-noaa git fetch && git checkout enable_biastee

[tomamdy]

I used cd ~/raspberry-noaa git fetch && git checkout enable_biastee and he has written the cammand in noaa.conf

but is that enough for starting the bias tee ?

Because nothing changed in receive.sh and receive_meteor.sh

I still believe that there is an error in the install.sh script is downloaded again . Nothing like :

read -rp "Do you want to enable bias-tee? (y/N)" if [[ $REPLY =~ ^[Yy]$ ]]; then sed -i -e "s/enable_bias_tee/-T/g" "$HOME/.noaa.conf" log_done "Bias-tee is enabled!" else sed -i -e "s/enable_bias_tee//g" "$HOME/.noaa.conf" fi

Or the old install.sh stays in a server.

[reynico]

Hi @tomamdy, after git fetch & checkout did you ran the install.sh script again? That way it'll replace the BIAS_TEE var value. You can also run sed -i -e "s/enable_bias_tee/-T/g" "$HOME/.noaa.conf" by now to avoid re running the whole install script.

How does your receive.sh line 28 looks like?

[tomamdy]

timeout "${6}" /usr/local/bin/rtl_fm ${BIAS_TEE} -f "${2}"M -s 60k -g 50 -p 55 -E wav -E deemp -F 9 - | /usr/bin/sox -t raw -e signed -c 1 -b 16 -r 60000 - "${NOAA_AUDIO}/audio/${3}.wav" rate 11025 this looks better, but I only know it tomorrow. Thank You and Santi! in advance. I cross my fingers.

[reynico]

Cool! I'll close this issue for now. Feel free to reopen it

[tomamdy]

But it doesn't works. Is it possible for me to test directly the bias_tee_enable, waiting for severall hours after a new install is not so pleasant.

[tomamdy]

For the .... time I have installed the script again and now it asked for enable bias_tee . That looks better. Could it be that install.sh was not changed, because nw I see that it is another install.sh.
