www.dxspot.tv is a dx cluster chat room facility designed specifically for the worldwide ATV
community with an easy to use DX cluster spotting interface for ATV contacts on all bands between
70cms and 3cms. Designed for mobile and PC use, Dxspot.tv includes an instant messaging facility
with other ATV operators via a dedicated IRC channel and a real time interactive map showing active
ATV stations and repeaters and reported ATV dx spots.

Home page
When you first visit the site you will see the following screen which is divided in to 3 main areas:
The interactive map
The map displays stations that are active and licensed TV repeaters with coloured icons to display
their status:
= Stations who are logged in and are “radio active”
= Stations who are logged in but have set their status to “just monitoring”
= Stations that have been reported in a DX spot but are not logged in
= Operational TV repeater
= Licensed but non operational TV repeater

Clicking on a station icon will display information about the station on 2 tabs:
o The first tab shows the station call sign, QRA and location
o The second tab includes any information such as station details and web site that
the operator has entered.
Clicking on a repeater icon will display information about the repeater on 3 tabs:
o The first tab shows the repeater call sign, QRA and location.
o The second tab shows tx and rx frequencies – repeaters are reported as being on the
band of their primary output but may have inputs / outputs on other bands.
o The third repeater tab includes the group website and other information such as the
repeater keeper’s call sign.
The map will also show any ATV or DATV DX paths that have been reported using DXcluster - clicking
on the line allows you to see the 2 stations in the QSO, the distance and the band reported. These
are shown by a coloured line depending on the band used – spots of narrow band beacons are also
possible to be reported via dxspot.tv and are shown as a dotted line in the appropriate band colour.
= 70cms
= 23cms
= 13cms and above
= 70cms NB beacon
At the top of map there are a number of drop boxes:
•
•
•
The time span for viewing spots is selected using the “timespan” drop down box.
The second drop down box selects which “Band” the spots and repeaters are active on.
Unticking the “Show repeaters” box clears the repeaters from the map and just shows active
stations and dxspots.
Global spot log
The area below the map shows a global spot log for all dxcluster spots which are identified with the
ATV or DATV description.
IRC chat window
To the right hand side of the screen is the dxspottv chat room window, which when you log will
show a list of all other active ATV stations and chat messages between the stations.
Registering
Before you can use the site you need to register by clicking the “register” button in the top right
hand corner of the main screen.
You will now see the register screen:
Enter your details, which will be used as to identify you on the interactive map and chat room. Enter
your first name and either your call sign or family name if a listener / viewer.
Zoom in and then click on the map to enter your exact location – the latitude and longitude will be
filled in automatically and your QRA will then be calculated.
Using DXspot.tv
After registration, you will then be returned to the home screen.
Enter your call sign and password in the box at the top right of the screen and press log-in.
The home page will now update as follows:
•
•
•
•
The interactive map will automatically be centred on your location
You will be automatically logged in to the dxspottv chat room
Your station location is now identified in green
The Submit New spot box has appeared
IRC chat room
The call signs of others who are logged in are listed on the right hand side. Type messages in the
white area at the bottom of the greay IRC window and press enter to send.
The idea is that you will use the chat room to line up tests between yourself and distant stations and
report progress as the QSO develops – the IRC has very little propagation delay and should be able
to be used for beam alignment etc.
Interactive map
Once logged in you will see your station on the interactive map identified by a green icon and
additional information is now available:
•
Clicking on station and repeater icons will display additional information on the first tab
which will show the station call sign, his locator and the distance and bearing of the station
from your location.
•
Clicking on “path elevation profile” will show the approximate path profile between your 2
stations
•
Once logged in, right clicking anywhere on the map will display the QRA of that location and
the distance and bearing from your station.
Submit new spot
Once logged in as a registered user, a new dialogue box appears to the right of the global spot log.
This box allows you to submit QSOs or reception reports via the dxcluster network.
To submit a spot, choose the correct band and mode, along with the remote station call sign and
locator – note that if the station is in the dxspot.tv database, it will automatically appear when you
start typing the call sign and the QRA will automatically be entered.
Enter the frequency of the QSO followed by any comments you wish to appear on the dxcluster and
press “submit spot”.
The dxspot should appear on both the global spot log and on the interactive map within 10 seconds
of you submitting the spot. – clicking on the line allows you to see the 2 stations in the QSO, the
distance and the band reported.
Edit my station details
Click on the tab above the IRC chat window, “Edit my station details”
Un-ticking the “currently active” box will change your station icon to yellow to show you are
monitoring dxspot.tv but not able to transmit or receive.
The free text box enables you to edit the details that appear on the description tab when clicking on
your station icon on the interactive map – the first icon gives the information you entered when
registering. It is recommended that you use the description box to say what bands you are operating
on and details of antenna and power output.
The next box allows you to enter your web site – this is an ideal place to enter your Tutioune
monitor web site so that the remote station can monitor your received DATV signal.
If you wish to update your location, click on the “set with map button” and zoom in with the
interactive map to set your new exact location.
Find station / QRA
This tab allows you to enter the callsign of a station in the dxspot.tv database – when you click
search, the station details will appear and the interactive map will zoom in to centre on his station.
Find QRA
A planned future enhancement is to be able to enter a QRA locator and the bearing and distance will
be reported back.
Standalone applications and mobile operation
Dxspot.tv was specifically developed using readily available web components – as such it is possible
run separate applications such as a mobile or web IRC client when out portable on a restricted
bandwidth 2G connection.
Simply log in to #dxspottv on the 'chat.freenode.net' with your mobile using a dedicated IRC client
and you will appear in the active stations list and able to message any stations logged in via
www.dxspot.tv .
A future planned enhancement will give an option whereby just logging in to #dxspottv will
automatically register you on the interactive map.
Help and feedback
A page has been set up on the BATC forum http://www.batc.org.uk/forum/ where users can give
feedback and help will be available from the ATV community.
