Amateur radio regulatory changes in Eire

https://www.amsat.org/notification-of-trademark-copyright-and-other-proprietary-information/

The low-band VHF Amateur Service allocations are now:
30.0-49.0 MHz 50 watts
50.0-52.0 MHz 100 watts
54.0-69.9 MHz 50 watts
69.9-70.5 MHz 50 watts

The national amateur radio society, IRTS, are to be congratulated on achieving amateur access to so much spectrum.

The ComReg document as written appears to mean amateur satellite operation is not permitted in these ITU Amateur-Satellite Service allocations:
435-438 MHz
1260-1270 MHz
5650-5670 MHz
5830-5850 MHz

Oddly satellite operation is permitted in 430-432 MHz but there are no amateur satellites there!

Transmitting to amateur satellites operating in 2400-2450 MHz is only allowed with a Special Permit, it’s not included as standard in the licence. Even with the Permit amateurs will be restricted to a transmitter output of just 25 watts.

ComReg limit which modes that can be used in each band by listing three-character ITU Emission Designators. For example X7F is among those permitted for the 54.0-69.9 MHz band and means Digital Amateur TV (e.g. DVB-S) can be used. Unfortunately it appears to be the only band where X7F is permitted, an unnecessary restriction.

The Emission Designators for digital voice modes such as D-STAR and DMR don’t appear to be listed anywhere suggesting they cannot be used.

In 2006 the UK regulator Ofcom adopted a Technology Neutral approach to amateur radio, they scrapped listing of specific Emission Designators and allowed all modes to be used. It is unfortunate ComReg hasn’t taken this opportunity to do the same.

King’s High School ARISS contact on BBC TV

King’s High School ARISS contact on BBC TV

On April 19 student Eleanor Griffin led the live question and answer session between King’s High School (GB4KHS) in Warwick and astronaut Ricky Arnold KE5DAU on the International Space Station (OR4ISS).

King’s High School strongly encourage their girls to develop their interests both inside and outside the classroom. This culture of empowerment led one of their girls, Eleanor Griffin, to apply to ARISS Europe (Amateur Radio on the International Space Station) for a highly prestigious link-up to the International Space Station.

When Eleanor Griffin was selected to hold a space conversation with an astronaut, she was inspired to set up the Warwick Mars Project, for students across the Warwick Independent Schools Foundation, to further interest in Space Science. Eleanor says: “The moon landings belong to the generation of our grandparents, and the International Space Station to our parents. What will happen in our generation? Will Mankind travel to another planet?”

After the ISS contact when asked what this incredible experience had taught her Eleanor replied “Just do it! No one is going to stop you, if you just go and pursue your dreams, you really can do anything.”

Radio hams receive Slow Scan TV from Space

Radio amateurs around the world are receiving Slow Scan Television images on 145.800 MHz FM from the International Space Station.

The transmissions by ARISS Russia are in celebration of Cosmonautics Day and should continue until 1820 GMT on Saturday, April 14.

Pete M0PSX of Essex Ham reports receiving good pictures using a colinear antenna.

Edmund Spicer M0MNG, a regular guest on the bi-weekly ICQ Amateur Radio Podcast, received an image at 1730 GMT on Wednesday, April 11 using a 5 element ZL Special Yagi and a FT-991. He said it was probably the best quality image he’s ever received from the ISS.

Others have reported receiving images using just a $35 Baofeng UV-5R VHF/UHF FM handheld radio and 1/4 wave antenna.

Russian ISS SSTV Event to Celebrate Cosmonautics Day

ARISS Russia is planning a special Slow Scan Television (SSTV) event April 11-14 from the International Space Station in celebration of Cosmonautics Day.

The transmissions are to begin on April 11 at 11:30 UT and run through April 14 ending at 18:20 UT.

Supporting this event is a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using amateur radio, specifically the onboard Kenwood TM-D710E transceiver.

Transmitted images will be from the Interkosmos project period of the Soviet space program https://en.wikipedia.org/wiki/Interkosmos

The transmissions which were coordinated with the ARISS scheduling team, will be made on 145.800 MHz FM using the PD-120 SSTV mode.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

The ISS Fan Club site will show you when the space station is in range http://www.issfanclub.com/

Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and subject to change at any time. You can check for updates regarding planned operation at:
