Re: Weatherfax audio file for testing

The iDevice software works but is not much more than a toy. Since there is no way to connect directly to the radio you have to have the audio up which is irritating and best and keeps the off watch awake for hours at worst.

Wefax is transmitted as FSK. Most mariners receive it using SSB (usually USB) which is why the seminal reference rfax.pdf reminds you to offset the tuning frequency by 1900 Hz. If you use LSB you'll need software that can invert the tones.
