Slow Scan Radio is a broadcast with several kinds of data. All data are auto-switching, so you don’t have to switch yourself. To be sure, with all data, we send all codes twice, in case the first time a code is distorted or down in the QSB.

We send both data (text) and SSTV images in the show. For the data Fldigi is the best choice, simply because ist is also used to make the show. Be sure to switch on the RxID on the top right part of the Fldigi screen, and set the frequency in the waterfall around 1500 Hz (the last, most of the time isn’t necessary). From that moment on the data will switch automatically, including the hellschreiber part at the end of the show.

About SSTV: all modern SSTV program’s and apps for smartphone, either Android or iOS are autoswitching, and with any reasonable signal strength they should choose the proper mode themselves, even if you switch on as the image has already begun.

There is also a version of Fldigi (called Flmsg) for Android. That one doesn’t support all mode’s that are used in the show though (it does support most of them), but it is also auto-switching.

There are several good program’s for SSTV. I use mostly MMSSTV or QSSTV. The first is for Windows, the second for Linux (available in Synaptic and via apt). For Android the app Robot36 is a good choice and for iOS CQ SSTV. It will even work in most cases by simply holding your smartphone before the speaker of the receiver. (Keep the distance short, and the audio volume very low, to prevent “ghost” images, caused by the audio reflecting to the walls of the room you are in!) Most of the time the smartphone apps will work even better than the PC program’s.
