The 70,0 MHz - 70,5 MHz band has been allocated to Amateur Radio use on secondary basis and included in the National Frequency Plan as published by the Malta Communications Authority (MCA) on 13 Feb 2015.
There are quite a few local stations interested in being active on 4 m.
Elle est organisée par l’association ORPB en liaison avec le Lannion Tregor Communauté et la Cité des Télécoms.
Enfin deux stations seront actives sous les indicatifs TM8PB et TM16EME.
Configuration 4 will be used:
- ARISS antenna 43
- Frequency 2395 MHz
- Symbol rate 2.0 MS/s
Ground stations F6DZP and IK1SLD will receive the signals and stream the video over the BATC server.
The video is expected to be received during 5 minutes.
This will mark the end of the Blank Transmissions.
No decision has been taken yet on the future use of Ham Video. We will keep you informed on any progress.

ARISS Europe chairman
- ARISS antenna 43
- Frequency 2369 MHz
- Symbol rate 1.3 Ms/s
Participants using the Tutioune receiving software can record as well as stream detailed parameters of the received signal. Please see: http://www.vivadatv.org/.
Reports are available at http://www.vivadatv.org/viewtopic.php?f=66&t=294&p=785#p785.
Thank you for your participation to the Ham Video testing campaign.

Contestperiod: August 11, 2013, 12:00 GMT – August 13, 2013, 11:59 GMT (end time last completed QSO).
Class 1: QRP (< 1.5 kW ERP).
Class 2: QRO (>1.5 kW ERP).
Stations can participate in one class only. No difference between single- or multi-operator stations or modes.
Exchange: Full callsigns, reports (e.g. 26 or R26) and final rogers (RRRR).
Final scoring: The total score is the sum of all points you received for all completed QSO’s together.
Logs via regular post can be sent to: A.F. Veldhuijsen, PA4EME, Westlandstraat 9, 6137 KE Sittard, The Netherlands.
Be sure you log contains at least the following:
- Your call, name, address and class you want to participate in.
- Stations in Class 1 (QRP) have to state details about the equipment they used in form of used output power and antenna gain. If no data about your station is given, you will be placed in Class 2. The power used for the calculation of the Effective Radiated Power will be the power measured at the output of your transceiver or active amplifier(s);
- The QSO list. As there are many logging programs available nearly every format is possible. But make sure that the log will show at least: date, time (to be specific: end time), call, report send, report received, locator and distance (equals points).
- With sending your log you also declare to have operated within the limits of your chosen Class, licence and local regulations when performing any activity that could impact your submitted score. Unsportsmanlike conduct can be ground for disqualification. Also you agree to have the log open to the public which might result in publishing your log on MMMonVHF or in the magazines DUBUS and/or Funk-Telegramm.
- Reception of a log will be confirmed in the same way it was received.
Special scoring for outside Europe stations: There will be a separate listing for stations outside Europe.
Certificate: All stations will receive a digital certificate showing the Class and ranking achieved.
