Howto: SDR/GQRX On Pinetab/Pinephone, Listen To Voice Transmissions (Filtering, Modes, Gain/Squelch)

Using Pinetab's internal SDR we show how to find and listen in to voice transmissions, with some examples. Leaving off from the external SMA threaded antenna port modification we use GQRX to filter, change modes, gain/squelch, and more to maximize sound quality.

We start off with a brief antenna comparison including no antenna, LoRa (Long Range Low Power) antenna, and a long dipole antenna. Showing how a short antenna can work just as well when designed for LoRa. Antenna theory discusses the formula needed to make the perfect antenna.

(You can get a Pinetab with built in RTL-SDR card from https://www.pine64.com when they become available again)
