Serial Port SDR

It sounds interesting. Beyond controlling RC vehicles, what would be some applications of software defined radios (SDRs)?

By the way, it looks like a USB-VGA dongle can be manipulated in a similar way:

We used to half joke that graphics card is in fact nothing more than very good and cheap DDS signal generator.

And as for SDR applications: most of modern radio devices use software defined radios and many modern radio interfaces cannot be reasonably implemented in any other way.

AM & FM audio transmission

Amateur TV

Ham radio

Point-to-point communication

Radio telescopy

Receiving satellite signals

Lots of opportunities to reverse engineer existing signals

A YouTube channel called The Thought Emporium has a series about using a sdr called the HackRF to make a radio telescope and a satellite receiver for a few weather sats.

There are not many commercial applications because it is usually much cheaper to implement in hardware and flexibility is not important.
