The recovered signal passes to the Relativistic Decoder, which interprets timing relationships across the surrounding transmission rather than measuring against one rigid timebase. This supports instant decoding, dynamic speed tracking, irregular human-sent code, bugs, paddles, Farnsworth timing, compressed contest exchanges, and unstable signals.

Decoded text appears letter by letter, teleprinter style, reducing the wait for whole words. Switch between CHARACTER and WORD modes from the receive pane at any time.

Recognizes European and DX formats and digs calls out of tightly compressed contest strings. Cypher distinguishes your call, a calling station, and the station being worked, so the contact record is never accidentally overwritten.

< RST> reads the calibrated S-meter at transmit time and inserts the actual measured report—never a fixed default or manual estimate.

Dynamic fields fill in at transmission: <ME>, <YOU>, <RST>, contest serials, cut numbers, and two custom fields (section, grid, power, name, etc.). One macro serves many contacts without rewriting.

A macro tagged <AUTOCQ> calls CQ on a schedule, listening before each transmission. Armed controls are clearly shown in the interface.

A macro tagged <AUTORESPOND> answers stations that respond, filling in call, report, and serial automatically. Cypher yields the moment a live QSO begins—automation reduces setup, not operator judgment

Cypher listens before every automated transmission. If the channel is occupied, it yields rather than talking over anyone.

Encodes and decodes 5–150 WPM, following speed changes automatically. No receive-speed knob. Moves naturally between slow practice, casual conversation, high-speed operators, contests, and hand-sent code.

The Noise Perturbation front end supplies a cleaner representation to the decoder, improving output when a signal is barely audible, intermittent, beneath a fluctuating noise floor, affected by QRM, or lost in a fade.

Cypher rejects noise artifacts and preserves continuity across disturbances. A selectable control also reduces persistent local background noise in electrically noisy environments.

Displayed directly on the audio spectrum. Narrow settings give aggressive noise rejection for slow code; wider settings support high-speed operation up to 150 WPM

Smoother, more accurate signal strength and SNR readings. The calibrated S-meter feeds the <RST> token, making the instrument part of the operating workflow.

Maps the noise floor, identifies troublesome regions, and improves signal discovery while avoiding noise artifacts mistaken for genuine CW.

Records decoded text, transmitted text, call signs, timestamps, and contact activity. Logs remain in non-volatile storage for later review or editing.

Cypher matches the approximate sending speed of the station being worked, subject to your maximum—smoother exchanges with less manual adjustment.

Shifts different received audio pitches to a consistent 600 Hz tone, reducing fatigue when moving between signals.

Compose a message and submit it for delivery. Cypher transmits when propagation and station availability permit—asynchronous Morse without both operators present.

• Direct: Connect to transceiver audio and key input for full encode/decode.
• Float: Select any signal on the audio scope for monitoring (transmit disabled).
• Loop-Back: Route the encoder into the decoder for practice and macro testing.

Operates over existing Wi-Fi or creates its own access point, moving from base to off-grid field use with minimal reconfiguration. Serves its interface to any Chrome browser on Windows, macOS, tablets, or phones. No internet required for normal operation.

A 240 MHz dual-core processor works with the host device for responsive control, visualization, and real-time processing in a unit under six cubic inches.

The complete manual opens from the Settings menu whenever an internet connection is available.

Cypher combines extreme weak-signal detection, contextual real-time decoding, 5–150 WPM operation, international call recognition, measured reporting, dynamic macros, automated CQ and response, automatic logging, visual filtering, and browser-based portability. It helps operators recover weaker signals, follow difficult fists, respond faster, automate repetitive exchanges, and stay ready when conditions are at their worst.
