Amateur Television – Workshop Nov 6th

Amateur Television Workshop – Analog or Digital?
Saturday Nov 6th @ 1:00 PM
At the Steel City Club House

On Nov 6th at 1:00PM the Steel City ARC will be hosting a workshop where we are going to ask for your input on setting up a video beacon here at our club house.  The purpose behind this is to see if there is still enough interest in ATV and to bring it back on the air.  If it turns out there is enough interest this could lead to an ATV repeater being put back on the air.

Back in ~2000? the Steel City Club house hosted an popular ATV repeater. While that repeater is no longer on the air, interest in ATV never really went away, which bring us back to today. At our last business meeting Karl, WA3VXJ brought up an ideal for bring back ATV by starting with an beacon transmitter. It turns out there a good number of ham interested still in ATV and eager to give it a try.

Bringing back ATV brings up a lot of new questions now.  Television has changed a lot now that it has gone digital. So the first question is which video mode do we transmit in good old fashion analog NTSC, or one of the two digital video modes  DVB-T or ATSC.   For Ham Radio the DVB-T equipment is out there and seem to be the most popular.  DVB-T is the commercial television format that is used around the world where as ATSC is the American format that is used in our country.  The problem with ATSC is the equipment is harder to find for transmitting where DVB-T can use USB dongles found on Ebay. To receive the DVB-T signal the ham would need to use a simple USB SDR dongle.

While researching for this article I was able to find an ATSC modulator on Ebay but so far I have not found any ham using one of these to modulate a video signal. So doing ATSC would be possible but might be harder to do for the average ham radio operator to set up and transmitter.  Receiving an ATSC signal should be a lot easier do to television made for the USA are build to receive ATSC.  Using either one of these devices still would require an purchase of an amplifier.

So on November 6th come up to the Steel City club house and learn more about ATV. Plus let us hear your opinion about bring back ATV to the ham radio community. We want to hear about which modes to use or since this is going to be a beacon maybe transmit in more than one mode.  This is open for all ham radio operators you do not need to be a member of SCARC to attend.

Literally “see” you on the air

ATV – Bring It Back?

UPDATE! – We are planning an meeting open to all ham operators interested in ATV we will be announcing the date soon.

As talked about at the Oct. business meeting:
Karl, WA3VXJ is interested in bring back ATV {Amateur Television} as a beacon for now. Steel City ARC had an ATV repeater set up on 426 Mhz. But now an then we get request about what happen to the ATV repeater. As you know television has change a lot, there is no more commercial analog TV transmitters any more. Everything has gone digital now, so if we set up ATV beacon what should we use for the Beacon? Good old fashion NTSC analog? digital? and if we do digital which format the American ATSC format or the European DVB format? If your interested in bring back ATV let Karl know. – Comments?
