Nathaniel Elijah has posted onhis blogabout how he was able to createan RTL-SDR based decoder for the FSK data transmissions sent out by the Efergy energy monitor. His program receives and decodes the transmissions, saving the data to an excel file for later analysis. ...
Status on the FSK Project Backlog [x] Addition of FSK device decoders to the build [x] Update build process to allow refreshes of rtl_433 components [x] Wire FSK device decoders into rtl_433_ESP code base [x] Create FSK Transmitter to em...
— was successfully decoded, providing proof of concept for the project’s first phase. We’re looking forward to the rest of the series, which will turn this into an actual decoder, and presumably add an encoder as well. Listeners of theHackaday Podcastmay recall we experimented with using...
This is used generally in the transmission of RF control signals, such as in a satellite- decoder remote control, or remote keyless entry system. The band cannot be used to send any continuous signal. The maximum output power allowed is governed by the duty cycle of the system. A typical ...
PURPOSE: A method for generating a frequency deviation signal of a communication terminal is provided to an FSK signal at low cost by generating the FSK signal using a software without using a hardware FSK encoder in a terminal having a hardware FSK decoder therein. CONSTITUTION: A character is...
Next, the zero crossing widths stream feeds the bit stream decoder. The process uses a set of rules to re-create a zero (0) or one (1) bit based on a relatively short sequence of width values. The decode rules use each width value, a trend sequence, and the total width value. Spec...
