Transmitting Oscar 100 DATV signals

2019-06-12T10:47:03Z

M0AEU:

To transmit DATV signals on Oscar 100 you need to be able to generate DVB-S2 signals on ~2400 MHz. This page outlines some possible transmit systems.

For a full guide to transmitting DATV on Oscar100 see CQ-TV 263 here: https://batc.org.uk/cq-tv/cq-tv-download/

==DATV transmit systems==
To transmit DATV on Oscar 100 you will need a system to generate DVB S or DVB-S2 (preffered) on 2400MHz.

[[File:Tyoical 100 transmit.jpg|600px]]

Systems include:

===Portsdown system===

The BATC Portsdown 2019 system using the LimeSDR mini

==Dish size and power required==

There are 3 key variables: dish size, power and symbol rate. The power received at the satellite varies with the square of the dish diameter, so for example a 1.2m dish will give 4 times the amount of power (6 dB more) than a 60 cm dish. The power density in terms of frequency will vary inversely proportional to the symbol rate. So a 250 KS signal will deliver double the power density (watts per MHz) at the satellite compared to a 500 KS signal of the same transmitted power.

Based on observed performance of the transponder, this table gives the power required and dish size to achieve the same level as the beacon at 250 KS:

[[File:power.JPG|600px]]

To see the full article, including how the power required varies with symbol rate and lower MER, see CQ-TV 263 - available for download here https://batc.org.uk/cq-tv/cq-tv-download/

UK ATV DX Records

2018-12-18T20:56:06Z

M0AEU:

This is a record of the UK DX records for each band. As well as the current record, it lists some previous records.

They are not complete and are based on trawling the forum activity pages and recent contest results - please update or let us know if you know better.

Note, these are UK records only (at least one of the stations involved was located in the UK) and only lists significant one way contacts.

World records are claimed based on the W6HHC list.

==World DATV records==

Ken W6HHC, maintains the record of the world DATV records here: http://w6ze.org/DATV/Known-DATV-DX-Records_2018.pdf

Please send Ken an e-mail if you know of a DATV QSO that should be added to this list! (via W6HHC@ARRL.net)

We need to make clear that this is NOT suitable to be used as a main receiver, just an off-air local monitoring capability within the transmitter. For reception of other stations you should always use a [[MiniTioune|MiniTioune USB receiver with a new Serit tuner.]]

------------------
F5OEO had included F4DAV's innovative LeanDVB receiver software within the Transmitter software build, and from software release 201612310 this is included in the core functionality of the Portsdown transmitter. The software is described on page 18 of CQ-TV 252 and at http://www.pabr.org/radio/leandvb/leandvb.en.html and can be configured from the Portsdown transmitter Console Menu.

On a Raspberry Pi 3 using an RTL-SDR, it will receive anywhere between 24 – 1766 MHz and decode at up to 1000KS/s and display on the touchscreen LCD. I used an RTL-SDR from http://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/ but there are cheaper ones available.

[[File:LeanDVB2.jpg|400px]]

The software is not as good as MiniTioune at digging signals out of the noise, and sometimes takes a while to lock, but is well worth playing with as a stand-alone test receiver. It uses the same parameters (frequency, SR, FEC) as are set for the Portsdown transmitter, either through the console interface or on the touchscreen.

For those of you who want to try to improve it's capability by tweaking the sample rate, the settings can be adjusted in the file /home/pi/rpidatv/scripts/leandvbgui.sh on the Portsdown software build. It is a shell script, so you will just need to restart the receiver to apply the new settings. If you find improvements, please publish them here and I will put them in the core build.

Getting Started

2016-08-05T12:23:31Z

M0AEU: /* Receiving and transmitting ATV */

Amateur Television is a fascinating area of Amateur Radio covering all aspects of video production, editing, transmission and reception of Television and has always been at the fore front of the technology revolution. Many stations are now transmitting Digital pictures (DATV) using the DVB broadcast standards and using video streaming technologies to exchange pictures with ATV operators around the world.

You're probably here because you want to know more about Amateur Television and so help you get to grips with the basics of our hobby, BATC has put together a series of "Getting started" guides.

A good place to start is by reading the [[Media:GettingstartedinATVbatc.pdf|Getting Started in ATV leaflet]].

Or take a look at this [[Media:Getting started Aug16.pdf|introduction to ATV presentation]].
Also available as an article extract from CQ-TV, our quarterly newsletter:
