Tools
Practical utilities for amateur radio operators. Built to be fast, no accounts required where possible.
CW decoder
Real-time Morse decoder with Goertzel filter tone detection. Feed audio from your radio or microphone — adaptive timing with WPM range control.
betaCW decoder v2.0
Beta rebuild. Timing now follows the sender rather than the slider range — decodes past 25 WPM without shattering slow characters.
liveCW trainer
Browser-based Morse code trainer. Set speed, length, and character set — listen and decode. No account required.
liveMorse generator
Type text and convert it to Morse code. Set tone and speed, then play it back with live highlighting.
liveQSO generator
Generate realistic rubber stamp QSO scripts for CW and SSB. Practice what a real contact sounds like.
liveSatellite tracker
Track amateur radio satellites in real time — ISS, SO-50, AO-91, and more. Pass predictions with frequency and CTCSS info.
liveRepeater map
UK repeaters on a map — FM, DMR, D-STAR, and Fusion. Set your position for distance, click a repeater for frequency, offset, and tone.
liveBand plan
Where to call on each UK band. Visual spectrum with the calling frequencies marked — QRP, FT8, SSTV, emergency — plus the legal power limit for your licence class.
liveAntenna calculator
Calculate wire antenna lengths for HF bands. Dipole, EFHW, and quarter-wave vertical with multiband harmonic analysis.
liveCoax loss calculator
Estimate matched-line and SWR-induced feedline loss for common coax and ladder line. See dB loss, power delivered, and how cable choice changes the picture.
Logbook
Lightweight QSO log with ADIF export. No account required. Data stays in your browser.
