The BPSK31 and QPSK31 modes are designed to assure communications with Signal-to-Noise ratio down to ( dB, for a PC at MHz or more).

Differential PSK is used to provide continuous phase changes when idle to maintain sync , and by allowing the receiver to measure phase difference from symbol to symbol, to reduce the effects of ionospheric Doppler phase changes which modulate the signal. PSK63F is a mode ideally suited for keyboard to keyboard chat. Modulation is bit-wise symbol synchronous, differential.

Synchronization at the receiver is straightforward because it can be recovered from the amplitude information. Aside from a standard radio transceiver and a computer with a sound card, very little equipment is required to use PSK All subsequent amplification of the signal must be linear to preserve the modulation waveform and ensure minimum occupied bandwidth. To decode PSK31, the audio whistle received from the transceiver's headphone output is fed into a computer sound card's audio input, and software decodes it.

In such cases the use of QPSK see below is often beneficial. To decode PSK31, the audio whistle received from the transceiver's headphone output is fed into a computer sound card's audio input, and software decodes it. This sound is then fed through either a microphone jack using an intermediate resistive attenuator to reduce the sound card's output power to microphone levels or an auxiliary connection into the transceiver, from which it is transmitted.

Use and implementation[ edit ] The text "Welcome to Wikipedia, the free encyclopedia that anyone can edit. To decode PSK31, the audio whistle received from the transceiver's headphone output is fed into a computer sound card's audio input, and software decodes it. Instead of the traditional frequency-shift keying, the information is transmitted by patterns of polarity-reversals sometimes called degree phase shifts. Soundcard to radio interfaces typically use isolation transformers on both the send and receive audio paths to eliminate hum caused by ground-loops.

PSK31 was enthusiastically received, and its usage grew like wildfire worldwide, lending a new popularity and tone to the on-air conduct of digital communications. The PSKR modes use binary convolution to generate two bits per varicode bit at the same symbol rate. When QPSK is used; after encoding into varicode , the binary signal is further transformed into a quaternary set of phase shifts. So, once it has been set up to run PSK31, a computer can be used to explore a variety of digital message transmission modes.

These devices incorporate the necessary impedance matching and sound level adjustment to permit the sound card output to be injected into the microphone input, send the radio's audio output to the sound card input, and handle the radio's transmit-receive switching. Over-driven operation results in excessive bandwidth, poorer reception and difficult tuning. When the operator enters a message for transmission, the software produces an audio tone that sounds, to the human ear, like a continuous whistle with a slight warble. Soundcard to radio interfaces typically use isolation transformers on both the send and receive audio paths to eliminate hum caused by ground-loops.

PSK31 is a digital communication mode for amateur radio. It is one of the most common and easy-to-use digital modes as a PSK31 station needs only to consist. PSK31 is a digital communication mode for amateur radio. It is one of the most common and easy-to-use digital modes as a PSK31 station needs only to consist. Narrow band modes such as PSK31 are low symbol rate, single carrier differential Binary PSK (called 2-PSK or BPSK) or Quadrature PSK (4-PSK or QPSK).

These slower speeds sacrifice throughput to provide greater resistance to noise and other interference. Conversely, PSK63 is increasingly used for faster exchanges, especially during amateur radio contest operating. The degree phase shift for a "zero" bit code occurs at a null amplitude.

Soundcard to radio interfaces typically use isolation transformers on both the send and receive audio paths to eliminate hum caused by ground-loops. In the most-commonly-used variant, BPSK31, binary information is transmitted by either imparting a degree phase shift a binary "zero" or no phase shift a binary "one" in each 32ms symbol interval. Instead of the traditional frequency-shift keying, the information is transmitted by patterns of polarity-reversals sometimes called degree phase shifts.
