DetailsOver on Hackaday we’ve seen a story about a Raspberry Pi Pico based software defined radio transmitter that is capable of transmitting SSB, AM, FM and CW anywhere between 0.5 – 30 MHz. The design generates an oscillator signal using the Pico’s Programmable IO. For AM/SSB it uses the PWM output pins to generate an RF…
DetailsSDU-X: SOFTWARE DEFINED DATA TRANSMISSION WITH ULTRASONIC TRANSDUCERS. Damian needed to get telemetry from his off-grid solar system 150 feet away, but didn’t want to spin up another unreliable WiFi device. Instead he came up with a clever solution that involves using ultrasonic transducers as the physical layer of a software defined communications system instead of RF…
DetailsThe WSPR-TX XP Plus is a standalone all band WSPR transmitter with built in GPS for the radio amateur experimenter. This Plus version is pretty much the same as the WSPR-TX XP except for two additional features in the Plus model: 1 WiFi 2 External frequency reference input Some quick features: 1: Standalone operation, PC required for configuration but not for operation.…
