Detailed Description

+

A simple (Audio) Frequency Shift Keying (AFSK) demodulator.

+

This node consists of two convolution peak-filters at the mark and space frequencies, a interpolating sub-sampler to match the baud-rate exactly and a PLL to lock to the symbol transitions. The node will decode the (A)FSK signal and will send a bit-stream (uint8_t).

+

Detailed Description

+

Decodes AX25 (PacketRadio) messages from a bit stream.

+

In conjecture with the (A)FSK demodulator, the AX25 can be used to receive packet radio or APRS messages. AX25 is usually transmitted as FSK in transition mode, means the bits aren't encoded by mark & space tones but rather as a transition from mark to space or in reverse. Hence the FSK node needs to be configured in transition mode.

+

The node does not process the actual AX.25 packages, it only checks the frame check sequence and forwards the AX.25 datagram to all connected sinks on success. The receiving node is responsible for unpacking and handling the received datagram.

Detailed Description

+

Implements a Baudot decoder.

+

Inconjecture with the (A)FSK demodulator, it enables the reception of radio teletype (RTTY) messages.

+

Please note that a baudot encoded char is usually transmitted in a frame with one start bit and 1, 1.5 or 2 stop bits. Hence this node expects to receive two bits for one decoded bit in order to detect the 1.5 stop bits reliably.

+

I.e. to receive a 45.45 baud RTTY signal, the (A)FSK demodulator need to be configured for 90.90 baud (= 2*45.45 baud).
