PhosphorFAX

RADIOFAX CODEC

Real-time HF weather fax receiver and sender. Coast-station charts painted line by line through your iPhone microphone, with phasing lock and slant correction — and a send path for a photo, a chart or the test card.

Weather fax and radiofax app for iPhone. Decode WEFAX charts from a shortwave receiver using your microphone and watch surface analyses, wind and wave forecasts and ice charts paint line by line, at IOC 576 and 288 from 60 to 240 lines per minute. Automatic start and stop tone detection, phasing lock, slant and centre correction, and charts that can be re-slanted and shifted after the broadcast has gone. Live spectrum, waterfall, line scope and signal health, a station list of 22 coast and meteorological stations with USB dial frequencies, and a send path that turns a photo, a received chart or the built-in test card into radiofax audio or a WAV. Works offline with no account and no extra hardware. Built for sailors, mariners and shortwave listeners.
