En uppdatering från FUNcube-teamet om FUNcube-2:

Limited testing of the FUNcube-2 linear transponder on the UKube-1 spacecraft has been undertaken during the recent holiday period.

This testing has shown that the transponder is able to work effectively and that it is capable of a similar performance to the transponder already operating on FUNcube-1.

AMSAT-UK and the FUNcube team have now submitted a detailed report on the testing to the UK Space Agency, who are the owners and prime operators of the UKube-1 spacecraft. It is expected that a meeting will be held with them late Jan/ early Feb to plan possible future testing and operations.

Ett nytt nummer av den fantastiska tidningen ESR Resonans har kommit från AMSAT-SMs samarbetsförening ESR. Ur innehållet (ej allt…):

• Omvärldsbevakning
• Frekvensomriktare, EMC-och radiostörningar
• 3,5 MHz radiofyr
• Månadens mottagare National HRO-500
• Plötsligt i Karribien!
• En ATU för symmetrisk matning eller “Steampunk ATU”
• Frekvensanalys – del 6
• Nästa nummer

Tidningen kan laddas ner här.

Mer info om ESR på deras hemsida.

Nytt nummer av AMSAT-DL Journal har kommit! Denna gång med bla. följande innehåll:

• Nytt runt ISEE-3
• Flyplansscatter – avancerade beräkningar
• 4M
• CanSat
• Protokoll från AMSAT-DL årsmöte
• FUNcube från Goonhilly
• Satellitnotiser

Det verkar vara fina signaler från ISS och deras bildsändningar.

Jag fick den här bilden med en  Gp antenn och mastpreamp.

Så har det satts ännu ett mottagningsrekord att ta signaler från satelliten DESPATCH. Avstånd denna gång var hela 4.695.550 km! Det är OK1DFC som har lyckats med denna bedrift med följande utrustning:
DISH 10m diameter, loop feed horn, LNA ATF 54143 optimized for 437 MHz 0,26dB N/F – 21dB gain, SDR receiver – Signal Hound 1 Hz-4,4 GHz with special RX software ( courtesy of Milan OK1FMF – thank you very much !) – HDSDR SW and PC DELL Vostro.

Teamet bakom UWE-3 meddelar nu att det kommer bli mindre aktivitet från satelliten:

Källa: ANS 348

UWE-3 was launched with FUNcube-1 on November 21, 2013, the team says they will
now be temporarily ending operations.

Today, more than one year after launch, there will be a temporary end of
operations caused by the end of funding.

However, UWE-3 is in a very good health condition with fully charged batteries
and operations may be continued depending on future research plans.

Without any reception from ground, UWE-3 will carry out a warm reset every four
days and switch regularly between the redundant on-board processors and radios.
Therefore, UWE-3 will switch back to its nominal frequency of 437.385 MHz.

Nevertheless we appreciate the extensive support we received from the HAM
amateurs in the past and hope that also in the future the status of UWE-3 will
be monitored with your support, like you did so many times in the past year.
Thank you so much for the very helpful cooperation in this respect!
