Amateur TV live streams

Amateur Radio Weekly reminds us that BATV has live streams of many of the TV repeaters around the world.

ATV DX

Some time ago, it was reported that amateurs were to carry out some tests on 10m and 6m with reduced bandwidth ATV. I have no idea if these tests were carried out.

I think in the 1950s UK broadcast TV was copied in South Africa and Australia when the MUF reached band 1.

ATV is one area of our hobby I have never tried. These narrowband digital tests sound fascinating. I am sure that they will be well published when successful.

Amateur television

One of the aspects of our hobby I have never tried is ATV apart from SSTV reception. My SSTV reception was with some free software using a smartphone on the desk. It worked surprisingly well. 

There used to be some interest in narrow band TV (30 or 32 lines) that used ordinary speech bandwidths much like the very early days of TV. 

These days there is quite a bit of interest in digital TV as the bandwidths are narrower and we have some experimental frequencies near 70 and 144MHz. One local has been building the Portsdown 4 transceiver based on the Raspberry Pi.

Amateur TV streaming

The BATC streams quite a few ATV repeaters and other stuff. Although I have never got into ATV, it is worth a peek no and again. Ideally, it appears Flash is needed to view some streams. The photo shows the stream from GB3NV, the Norwich TV repeater.

TV webSDR for Oscar 100?

Although I regularly check the narrowband SDR at Goonhilly in Cornwall, I am not aware of the equivalent for amateur TV signals. I know there are various standards and this may make such a RX difficult. I am aware of the SDR showing activity levels in the wideband transponder, but not actual TV signals. If you are aware of one, please let me know.

By the way, activity on the narrowband transponder still seems low.

5.6GHz ATV

Apparently it is easy and low cost to get on 5.6GHz ATV using drone modules available on the internet. A figure of £20 was quoted. A very useful point of reference is this wiki:

Local to me G3KKD has 5.6GHz gear amongst others.

CSG Shop

This is Latvian online shop, but I have heard some good reports of it, although I have not (yet) used it myself. They do some good GPS kit as well as 2.4 and 5.8GHz ATV modules.

Amateur TV

There is always something in our hobby that we cannot do. One of these is ATV, which despite being interested, I have never tried. The BATC streams many TV repeaters, so you can take a peak without investing in TV gear.

CQ-DATV

TV is one part of our hobby I have never tried. After all, it is hard to do everything! If you are interested in DATV, issues of CQ-DATV may be downloaded freely.

See http://cq-datv.mobi/48.php  for the latest issue.

BATC videos on YouTube

See https://www.youtube.com/channel/UCUWLnUZllytlcCFd93tnBzw/videos .

Southgate News reports that videos of the recent BATC convention talks are now available on YouTube. I watched some of these when they were steamed, but it is good to hear they are available offline.

CQ-DATV mags free

See http://cq-datv.mobi/ebooks.php .

CQ-DATV is available for free download. I have not tried amateur TV but some remarkable results are being achieved by DATV in the 146-147MHz band. Like all things in our hobby, you can only do so much. I think the use of digital techniques has given amateur TV a new lease of life.
