Online / Web based Kiwi SDR Weather Fax decoding on demand and as a service

Continuing our series of Amateur Radio As A Service (ARAAS) this post looks into another built in feature of the famous Kiwi web based SDR, the ability to decode FAX transmissions on the fly.

On the HF bands Fax is mainly used to transmit weather related information.

You can find the locations and schedule HERE

So go find a kiwi sdr station at http://sdr.hu in our example we used I1CRA / IZ1GLG (thank you)

Locate the above panel, which will appear bottom right side of the web page, in the extension drop down choose fax. You will see the screen changes, the fax decoder and fax control panel are now seen.

Given in this example we are using the kiwi sdr located in Italy, we can use a frequency in Europe, for the best results, if you select the top frequency, then click next until you find an active one.

You should start seeing some nice decodes as seen in the screenshots above

Retevis sponsor us a RT-95 radio for the vectra *Benidorm or bust*

Retevis have kindly donated a pair of RT95 FM analogue radios for us to use in the Benidorm or bust rally in June. Here are a few pictures of the installed unit in our vectra. Looking rather solid and good looking!

Not the wire is drilled through in the above picture, for a more permanent fixture.

Take a step back and see how compact the radio is and how well it fits in the glove box, for a discreet place to hide it away.

Review: Retevis RT95 dual band analogue FM radio

As you can see above the retevis rt95 has a well lit display and microphone for easy use in the dark.

This radio will pick up FM satellites when attached to a reasonable antenna.
You can hear AO-85 on this pass!

This is another FM Satelliet called SO-50

First thing you will need to do when you get your FT95 is expand the frequency range, before programming anything! (you will lose the settings and saved copy will not load!)

Important to ensure PTT is pressed to make the band change.

RT-95 can expand into OFCOM Business lite radio license as discussed in this video

Ensuring Low power (5 watts max) this shows the licensed frequencies I could use.

Here is another example of how diverse this radio is, we can receive APRS packet data and plot it on a map.
