Black Cat HF Weather Fax is a fully featured programme that decodes and displays weather fax transmitted over shortwave radio. This is an interesting solution for anyone that needs up to date weather information off grid with no internet or during a power outage.

With a suitable suitable shortwave receiver, no transmission required, you can tune into a weather fax transmission and feed the audio into your computer’s sound card input or iOS or tablet device and start receiving and displaying weather fax images in minutes.

Black Cat HF Weather Fax integrates with the SDRPlay SDRUno software package via the free Black Cat Systems plugin. Instructions for configuring both are available on this page.

Control of SdrDx, SdrSharp and Elad SW2 is also built in.

A schedule of worldwide weather fax transmissions is available here: rfax.pdf

This leads us into the subject of resources that can function off line. Either during a power outage, in remote locations away from internet and during an internet outage.

We will have a dedicated page with recourses that are must for off grid ‘survival’. We will be carrying out some experiments using a Short Wave receiver, an iPhone and a Windows laptop, the GPD Pocket 2.
