border images

What do the border images represent?
I suspect spectrum / FFT (frequency domain) display.
Another possibility might be time domain signal display of digital samples.

The 100uF electrolyte capacitor connected to the speaker has wrong polarity. It's correct in the schematic in fig 1-2 however.

This is in reply to John’s error. My kit did not come with a 10pF capacitor either however the book just says you can experiment with a 10pF instead of a 100pF. I do not believe it is crucial to the project.

Actually, a factual or historical mistake, so I selected the only option, "Question or request for clarification." This paragraph states that the Sun interferes with radio reception because it overwhelms transmissions with its own electromagnetic interference! Obviously, the Sun does not do this. Its effects on the ionosphere are correctly stated later in the book. I would just delete this paragraph.

Marconi believed that the Sun created some type of (Faraday) "shield" around antennas during the day to explain the difference between daytime and nighttime propagation, and he also coined the term "antenna" from the Italian for "little pole" for his invention of the Marconi vertical antenna.
