ARISS are hoping to establish an amateur radio 2.4 GHz TV beacon and a CW beacon on the International Space Station. The minutes of the ARISS International Monthly Teleconference for June 19 carry this report on the status of the amateur radio equipment for the ESA Columbus module.
Gaston, ON4WF said the HamTV project is progressing. There have been discussions with ESA about the possibility of adding extra units to the HamTV transmitter that is being developed by Kaiser Italia. This is acceptable in as far as the KI unit under construction does not need to be modified.
A so called “Video Beacon” will be added externally to the HamTV unit. This beacon will allow automated DATV transmissions more or less permanently. The content of these DATV transmissions will be uploaded from the ground through existing channels and transferred to the Video Beacon on request. This function will also be used for educational purposes. Moreover, astronauts could record footage and load it into the Video Beacon for automated transmission.
Another additional unit will be a CW beacon transmitter delivering a small band low power signal (100 mW) on a frequency nearby the HamTV frequency. This beacon will transmit permanently and use the second ARISS L/S-band antenna. This offers ground stations signal reception with large S/N margins, facilitating antenna tracking and signal acquisition, especially at the beginning of a pass. The CW Beacon will transmit telegraphy signals, alternating its identification (call sign), a continuous carrier and possibly some telemetry comprizing onboard parameters (temperature, pressure, humidity, ambient sound level, etc.).
Lou W5DID suggested that we may be able to power it from the packet module already on the ISS, making it simple to operate.
ESA is being asked to address the cost of the Safety Package and testing such as EMI tests and outgassing tests for these additional units, but development and manufacturing will be supported by ARISS. A cost estimate is being developed for our team to build the units. A funding campaign will be set up to collect donations to cover the cost.
Regarding the amateur radio station in the Russian Service module the minutes say:
Kenneth N5VHO reported that an onboard power issue somewhat impacted ARISS radio operations. The air purifier for the ATV [Automated Transfer Vehicle] has needed to be plugged in, recently, in the Service Module (SM). The ARISS radio in the SM was turned off while the purifier was being used. The radio is turned on by the crew for school contacts and when the crew gets on the air for random contacts, as Astronaut Kuipers has done in the past few weeks. The ATV will be docked at the ISS until late September.

Change to the IRTS 40 Metre News Frequency
The present 40 metre radio news frequency has become increasingly busier on Sunday mornings. This has lead on occasions to some difficulty in the reception of both the bulletins and the reports on the transmissions. It has been decided, therefore, to move the transmission of the 40 metre news to a new frequency of 7123 kHz on and from Sunday the 1st of July 2012. This frequency was selected after monitoring a range of frequencies over a period of time by amateurs who use this particular transmission of the radio news bulletin.
HF News Readers Needed
Additional HF newsreaders are required to cover the 40 & 80M news broadcasts over the summer months due to holidays etc. Any IRTS members that wish to join the panel and are available to read the HF news would be most welcome. Please send an email to info@irts.ie

2012 Leap Second
The last minute of June 30th 2012 UTC will be 61 seconds long, the extra second being a "leap second".
Leap seconds are introduced to maintain synchronisation between atomic clocks and more traditional time scales such as Greenwich Mean Time. These leap seconds are introduced approximately every 18 months, at the end of June or December, usually to give the Earth's rotation a chance to catch up on our clocks. In Ireland and the UK the leap will take place close to 1am local time.
This leap second represents a chance to record the leap second by DXing an international time signal (e.g.
Rugby on 60kHz, Moscow on 4.996 MHz). As the future of leap seconds is under discussion at the ITU, this could be the last chance to have a QSO with a leap second!

Double CME targets Earth
Active sunspot AR1504 is facing Earth and hurling coronal mass ejections (CMEs) in our direction.
A fast-moving CME that left the sun on June 14th is expected to scoop up another CME already en route and deliver a double-blow to Earth's magnetic field on June 16th.
Weak-to-moderate geomagnetic storms are possible when the clouds arrive.

Ofcom Wireless Telegraphy Regulations 2012 Statement
Ofcom has published a statement on its decision to make the Wireless Telegraphy Regulations 2012 control interference from apparatus during the London Olympic Games and Paralympic Games.
The report notes that the BBC and the RSGB both also expressed the view that the Proposed Regulations should be extended to address undue interference with wireless telegraphy used for purposes other than public safety.
One responder to the consultation pointed out that “..... the powers that are conferred under these proposed regulations to prevent harmful interference should not be limited either geographically, or in time, this legislation is needed to generally protect radiocommunications, and not just for the period of the Games. This is because the level of electromagnetic pollution is steadily rising, even from devices meeting the requirements of Harmonised EMC standards.”
Another responder said that “if the existing EMC regulations laid down in European law are policed correctly 24/7, then none of this would be necessary.”
The statement, Decision to make the Wireless Telegraphy (Control of Interference from Apparatus) (the London Olympic Games and Paralympic Games) Regulations 2012, can be found here.

Worked All Britain Olympic flame award
The Worked All Britain Awards Group has organised a special award to coincide with the passage of the Olympic flame around the country.
Various amateur radio clubs around the UK will be operating from locations along the route used by the Torch Bearers for that particular day. They will use the callsigns G4WAB and G7WAB. The main call will be G4WAB, the exceptions for this being Shetland and Orkney, Jersey and Guernsey, when both callsigns will be used on the same day.
There will be three versions of the award, depending on the number of stations worked: Bronze, Silver and Gold. The award will be issued as a PDF as standard, with the option of a paper version for those that require it.
Full details of the cost, route and club stations are available on the WAB website, http://www.worked-all-britain.co.uk/.

IRTS Field Day Contests
Next weekend - Saturday and Sunday, 2nd and 3rd June 2012 - the first of the year's IRTS field day contests takes place, with CW field day, which runs from 15:00 UTC on Saturday to 15:00 on Sunday.
The IRTS CW Field Day contest coincides with similar contests in other
European countries, so there should be no shortage of QSOs.
While the emphasis in these contests is on portable operation, fixed station QSOs are welcome.
See www.irts.ie/contests for more information on this and other contests.
As previously announced by the IRTS, there are some rule changes this year - these are highlighted in the contest rules.
The Field Day series of contests continues in July with VHF/UHF Field Day, while HF SSB Field Day takes place in September.

New transatlantic 144MHz beacon GB3WGI
Spotted this earlier!LINK
On the 18th of May, 2012, Ofcom issued a NoV for another propagation beacon to test the possibility of a 144MHz transatlantic path from the UK.
Located at Lough Navar Forest in Co Fermanagh, Northern Ireland OSI 06599 57718, 349m asl level with a clear take off over the sea, GB3WGI ("West GI" will radiate on 144.487MHz towards North America, initially with an ERP of 100 Watts relative to a dipole, with plans to increase this if licensing allows.
This beacon was made possible due to the generous donation of a transmitter by Brian Justin, WA1ZMS, the man behind the US 70MHz beacon, and NoV holder, Gordon Curry GI6ATZ who is providing the site and site services.
This NoV is particularly welcome from Ofcom in what is clearly a busy Olympic year, and the VHF weak signal community in the US and the UK thank them for their efforts.
No date is yet fixed for the installation of the beacon, but plans are well under way and an announcement will be made in due course

Logbook of the World
Logbook of the World (LoTW for short) is an online QSL
system - an alternative to paper QSLs for award
credits. ARRL, which runs the LoTW system, have
announced that LoTW now has 50,000 users. These users
include more than 100 EI radio amateurs. QSLs from LoTW
can be used towards DXCC and other ARRL-sponsored
awards. Recently it was announced that LoTW QSLs will
shortly be valid for operating awards issued by CQ
Communications.
A review of LoTW users shows that call signs from all
but one of the 340 current DXCC entities have, at some
stage or other, uploaded logs to LoTW - the one entity
that has no participation in LoTW is Mount Athos. Most
major DXpeditions upload their logs to LoTW, some
immediately the DXpedition finishes and others after a
delay of a few months. Experience has shown that
contest stations have a particularly high
participation in LoTW.
While paper QSL cards are still popular, anyone
interested in maximising DXCC credits should consider
using the Logbook of the World system.

Huge sunspot AR1476
Huge sunspot AR1476 is crackling with M-class solar flares and appears to be on the verge of producing something even stronger.
The sunspot's 'beta-gamma-delta' magnetic field harbors energy for X-class flares, the most powerful kind.
Radio operators are recording strong bursts of shortwave static from the sunspot as it turns toward Earth.

GB3LV repeater back on the air
GB3LV - the north London 70cm, IRLP and Echolink enabled repeater, is back on the air again after having been off air for a day or so with an intermittent fault. GB3NL and GB3EN were unaffected. The fault has been rectified by the rapid actions of Roger G8IUC.
Roger indicated that an upgrade/maintenance action was due on GB3EN (the Amateur TV repeater in Enfield) and that a new antenna, feeder and other sundries would be installed. The time scale for the installation is not known.
