We are happy to confirm our forthcoming 144 EME operations from 'la Dominique'.
For the 'smallest stations' please consider to have a try during our Moonrise as we will have some ground (sea) gain,.our location is surrounding the seashore without any obstacle for all moonrise. The figure for all of us to beat is 37 valid QSOs( 6V7A )

Latest news from J79DI

Very good activity yesterday but we still experience very rapid change in conditions: not just weather conditions but also reception level !!!A lot of signals filling the waterfall sceen for an hour, then it was very quiet, specially during the US window ( no activity ?)

Operating recomendation : Please spread over +/- 1kHz max and when J79DI is calling an identified station , please listen and wait until QSO is completed . Thanks in advance it will help to make even more contacts ...

No specific problem has been identified with the reception system , but very rapid change of polarisation are observed . Please consider that weather conditions are quite tough here , tropical rain and very heavy wind !!!

Skeds : If JA station ( but only JA and due to frequency limitation) want to arrange skeds please contact via moon-net list or JT65 EME link.

Change in end date of expedition : We must leave the island on Monday 4th at 15h00. We will try to be still operational on Sunday 3rd December night but we have to pack then must join the boat on time ! 73 Jacques and Jean-Marc

On the way to Sea Cliff ....

On 24th November at 12h05 (UTC) the team is on the way to Sea Cliff with all the equipment safely on the boat. Apparently just a "small" damage to the antenna container requires further assessment on arrival. ! So far, so good and weather is reported fantastic ... !
