SSTV pictures can be viewed on online SSTV cams such as these.Ī simple cable to connect your laptop computer to your transceiver is described here. These videos show some of the variety that is SSTV activity. Introduction to digital picture transmission (including Easypal) by VK3AML Some unexpected portable SSTV (in the middle of the day on 80m) Enjoy the videos below for various aspects of SSTV activity. Have regular SSTV nets where you'd be most welcome.
Both analogue and digital SSTV exists, with digital often providing sharper pictures and the ability to send other types of data. However there is localised SSTV activity on other bands such as 80 and 40 metres. SSTV has various frequencies that are popular. Transmit your transmitter's output power should be set at around 30 to 50% of that which you'd use on SSB. Again that needs a cable to connect to your transceiver. (easily downloadble off the web), (iii) an interface cable conveying to and from the transceiver and (iv) an HF SSB-capable transceiver, preferably equipped with VOX (voice operated transmit).Īnother option, possibly better for portable SSTVers is to use a mobile phone app like DroidSSTV. You need (i) a computer with sound capabilities (like they all have now), (ii) suitable software However setup and equipment is very similar. SSTV predates modern computer based digital modes.
If images are kept simple with high contrast and a slower transmission mode (selectable on the software) is used. As you'll see it's surprisingly effective with low power, especially This readily gives coverage over hundreds or thousands of kilometres, just like SSB voice.
With a bandwidth of a few kilohertz (as opposed to megahertz) SSTV tranmissions are narrow enough This means that SSTV pictures can be sent with an ordinary SSB or FM voice transmitter. The advantage though is its narrow bandwidth. Unlike Fast Scan TV, which has movement, SSTV is a series of still pictures. Slow Scan TV (SSTV) is a way amateurs send images over the radio.
