1240-1300 MHz ham radio band discussed by CEPT ECC SE40

CEPT LogoCEPT ECC has released its news summary for January 2020 that includes the SE40 Rome meeting on January 14-16 which discussed compatibility between RNSS and Amateur Services in 1240-1300 MHz.

The coexistence between the Radio Navigation Satellite Service (RNSS) and the Amateur Services in the frequency band 1240 – 1300 MHz was discussed by the CEPT ECC SE40 Working Group. The IARU presented possible scenarios to be taken into account in the sharing studies. The meeting agreed that further work on this WI will be developed in the SE40 Forum.

The papers, Amateur vs RNSS – Amateur scenarios – initial ideas, Draft Report RNSS vs Radioamateur, and Draft Minutes, along with other SE40 Rome meeting documents can be downloaded via

BBC TV’s Great British Railway Journeys is expected to show former MP for Enfield Southgate, Michael Portillo, using 5.6 GHz amateur radio to bounce a signal off the surface of the moon.

In 2017, a team led by Noel Matthews G8GTZ and Brian Coleman G4NNS made several visits to Goonhilly Earth Station in Cornwall to use the 32 metre GHY6 dish for 3.4 GHz and 5.760 GHz Earth-Moon-Earth (EME) operation. During one of the visits, Michael Portillo and the Great British Railway Journeys team visited and filmed a sequence including EME operation.

The show will be broadcast on Friday, January 12, 2018 at 6:30pm on BBC2.

Described as “Going to the moon by way of the Cornish Riviera” the sequence will show Michael talking to Brian G4NNS and operating his station under supervision to “talk to the moon” and hear his echos coming back.

The BBC description reads:

Steered by his early 20th-century Bradshaw’s railway guide, Michael Portillo boldly goes to the moon by way of the Cornish Riviera Express! On the trail of an historic achievement made at the dawn of the Edwardian era, he investigates the first radio signal to be sent across the Atlantic. In Plymouth, Michael uncovers what happened to surviving crew members of the most famous ocean liner in history, the Titanic. And at Fowey, he rediscovers a lost literary figure known as Q, who immortalised the town in his novels.

The show will be available online for 30 days from January 12 at

Ham radio EME for JOTA

Geert Jan de Groot PE1HZG reports  that radio amateurs will be using the PI9CAM Dwingeloo 25 meter dish during Jamboree On The Air (JOTA) this weekend. On the AMSAT-BB he writes:

In the Netherlands, the CAMRAS foundation took over the large radio telescope of Dwingeloo. This year during upcoming JOTA weekend, several stations will try to make QSO’s using QRP EME via the moon using WSJT and the telescope (accessible via WebSDR) as Receiver With Large Ears.

Information, in Dutch alas, can be found at
http://www.camras.nl/index.php?option=com_content&view=category&layout=blog&id=85&Itemid=109&lang=nl

You should be able to listen in using the same WebSDR station.

Please join me to congratulate the volunteers of CAMRAS, and especially
Frans PE1RXJ, for organizing and facilitating this impressive feat.

June 13 is the 50th anniversary of the first UK amateur radio moonbounce (EME) contact which was made by Peter Blair G3LTF from Chelmsford in Essex.

The RSGB GB2RS News Service reports:

July 2014 marks the 50th anniversary of the first time that amateur signals from the UK reached other parts of the world by bouncing off the moon, a technique now known as moonbounce or earth-moon-earth, EME. In the July 1964 edition of Radio Communications the RSGB announced that at 20.20 GMT on June 13, 1964, G3LTF at Galleywood, Chelmsford, and KP4BPZ in Puerto Rico, made contact on 430 Mc/s [MHz] by bouncing their signals off the moon. Signal reports were RST459 both ways.

A further contact took place one hour later. KP4BPZ was fortunate in having the 1000ft [305m] radio-telescope dish aerial at Arecibo, Puerto Rico at his disposal. G3LTF’s equipment included a 15ft [4.5m] dish aerial and an AF139 transistor preamplifier for reception. Power input to the PA was 150 watts. What is more remarkable is that Peter, G3LTF is still active on moonbounce and is one of the world’s leading pioneers.

The RSGB offers Peter, G3LTF our heartiest congratulations on this 50th anniversary of his achievement.
