I finally got it. From the command prompt, issue the following to add the key: sudo wget -O- https://download.opensuse.org/repositories/home:/astronopteryx/Raspbian_11/Release.key | gpg --dearmor | sudo tee /usr/share/keyrings/echoes-archive-keyring.gpg Then create a new echoes.list file under /etc/apt/sources.list.d and add the following: deb [signed-by=/usr/share/keyrings/echoes-archive-keyring.gpg] https://download.opensuse.org/repositories/home:/astronopteryx/Raspbian_11 / That is what worked...

Would someone provide me with instructions on how to add the astronopteryx repository to a bullseye setup? Many thanks, Clint

Thank you, Giuseppe. No problem on that. I'm very pleased with this program. I will be trying to generate interest in it at our next local radio club meeting. Clint

However, when I run a system update, I get the following message: You might want to run 'apt --fix-broken install' to correct these. The following packages...

Hello Joseph, I know it has been a few months but I thought I would comment. What you are seeing is what some call the "center spike". It is an artifact found with R820T and R820T2 RTL-SDR dongles. I had the same problem when I first ran echoes. My solution was to right click on the tuning ruler where the tuned frequency is on the waterfall and place a notch filter there. Set the filter bandwidth wide enough to cover the center spike. Then offset the detection window away from the notch which looks...
