DX with FreeDV plus Video
Currently the FreeDV plus Video DX record, 1,600 miles, is held by Ray, W4BCX. In July and August of 2016 he and Rick, WA6NUT, had FreeDV+ QSO's, with W4BCX successfully receiving FreeDV together with the video clip being sent by WA6NUT. During the August QSO Ray recorded Rick's video as a ".49" video file (band conditions on 20M were poor the day of the recording). You can view this video by downloading the zipped .49 file (Link 1 below), unzipping the file and playing it on the RxReplay7A application (included with the FreeDV+ software). You'll want to adjust the picture brightness for better viewing. The greenish tint resulted from Ray's receiver being tuned 2-3 Hz off frequency. Link 2 below, recorded by W4BCX in October 2016, shows correct tuning and the effects of propagation (fading) and and some tuning adjustment (see screenshot below). Compare these videos with the WNDSURF1.49 video (also included with the FreeDV+ software).

Or with the BATC Live Stream: There's another way to monitor your FreeDV plus Video signal, in real time, as it is being received by a distant station. The British Amateur Television Club (BATC) provides live Internet streaming so ATV'ers can monitor their own signals as well as the signals of other ATV stations.

When it is streaming, the FreeDV plus Video live stream monitors 14236 kHz, with audio from a FreeDV decoder ("1600" mode) and video displayed from ZL2AFP's receiving software, modified for compatibility with FreeDV. The receiving station is at Buena Vista, Colorado. You can check the status of the stream by clicking the link below (to conserve bandwidth, the BATC requests that members refrain from streaming 24/7).
