Do you want to get your weather charts without using an internet connection or a dedicated computer? HF Weather Fax lets you receive marine weather radiofascimile transmissions, using the audio from your HF marine radio. Just set it next to the radio's speaker or headphones, tune in a weather fax frequency, and watch the images come in. The app can also receive audio from Bluetooth audio devices.

HF Weather Fax is perfect for mariners who want to be able to view the latest weather reports and forecasts.

Received fax images can be manually or automatically saved, and viewed later. You can also export them to your computer using iTunes.

There is also a built in copy of the NOAA/NWS Radiofacsimile schedule, and an option to download the latest copy of the schedule from the NWS website.

Fun app

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

HF Weather Fax app is a winner

Just purchased this app for my iPod Touch based on good results with the NAVTEX app. I use a very stable and sensitive general coverage receiver with a longwire antenna. As mentioned in the instructions on the website, a strong signal is necessary for a clear fax reception. Have used other weather fax programs with my laptop and receiver, and am impressed with the quality of the faxes this will capture. I would give this a five-star rating if you had included a tuning meter (showing the signal spectrum) similar to the NAVTEX app -- for fax this would be a great benefit to visualize how to tune your radio for the max signal peaks. Otherwise it will take a good deal of experimentation and may frustrate some users.

Overall this is an excellent app. For radio enthusiasts Black Cat Systems has created some excellent products. Thanks!

Offshore Weather Fax Required

I singlehand a small boat offshore. I needed access to weather information for my sail to Hawaii and this program, combined with a Sony 7600GR receiver and a cable or two, does the job. I am able to receive weather fax data and can plan my route accordingly. I have experience with the same companies version of this software for the Mac laptop and it is a bit better in having a choice between greyscale and black and white modes, but on the flip side the tuning window on the IPad version is better. The developers support is very prompt and responsive to questions. This software is solid, easy to use, the developer stands behind it, and renders what you need when and how you need it. I highly recommend it.
