I had high expectations. The reality is that it is a great idea, but does not really work in real life. Aside from other noises, after everything is quite it still bring a very poor quality, non synchronized fax view that is useless. I wish it would work as I wanted it as a backup for my HF SSB computer weather fax program. I gave it two stars with hope that sometime in the future it will be tunes and synced better
This decodes HF FAX signals, hence the name. It will not do satellite images, nor does it claim to.
Just remember the schedules are in UTC time, during summer that isn’t the same as nearby London time. Had me scratching my head but not any fault of this great app.
This app does not load anything but white dots on a black background
Just like other modes of downloading HF weather fax, reception is everything. This app is so uncomplicated! I had better luck using a pair of earphones lying near my iPad mic.
This app is great for decoding NOAA faxes from coastal CG stations but also creates artistic images when attempting to decode from NOAA satellite transmissions
I set the iPad in front of the receiver speaker and it immediately and correctly decoded the wefax images.
Please add support for Apple Watch.
Decoded on FLDigi using my Icom 7200 with a W5GI while simultaneously trying to decode withe the Black Cat Systems app. No decode while FLDigi had perfect copy. Don't waste your money.
Using this as cruising. Works well.
