Obtaining electronic parts for free - off the street

Some areas have annual kerbside 'hard rubbish' collections. Many electronic items, some still working, get left out.
They can be a source of parts that more modern items lack. For example old 'slide rule' dial AM/FM transistor radios
have variable capacitors that newer push-button tuned digital radios lack. These can be useful in various receiver,
transmitter or antenna coupler projects such as described elsewhere here.

Other items may be fixable by someone with a little experience in electronics. Then there are the cast-offs whose
former owner doesn't know or doesn't care about their value. For instance old telephones or early transistor radios.
Clean it up, sell it on eBay and there's the funds to buy a Nano VNA or some good books.

The videos below show some street finds and possible uses for them.
