Raspberry Pi 5 RTL-SDR V4 (Bundle)

After I found the link to download the software, things got a lot easier.

The book is a good introduction to using Python on the RPi 5. While some of the early examples aren't that useful -- it's pretty easy to calculate resistors in series and capacitors in parallel without a computer -- they do build to more complex problems.

The SDR hardware seems good with the exception of the SMA connector on the antenna. It had not been crimped and pulled off with only a tiny tug. Luckily I have an appropriate sized crimping tool and was able to repair it. But a little more QC would be welcome.

Good book giving me a lot of new ideas.
But I miss links to all the programs. I could not find such links. It is a bit heavy to type everything in?

Pretty much the same as the previous version, despite the use of the new Python library for I/O, imposed by the use of the Raspberry Pi 5. Parts are just taken over, (with minor adaptions) from the Raspberry Pi 5 Essentials book, which I own. Explaining a capacitor and a couple of pages later jumping into the mathematics of filters (which by my means is worth a couple of books by its own) did raise my eyebrows. More than half of the book in fact has no value for licensed radio amateurs. The "real part" begins at about 3/4 of the book, but is well known matter if you are member of a radio amateur club. I own almost every book of Elektor, and repetition and/or small adaptations are becoming the thin red wire of the author throughout his latest releases of books.
