-  * **30cm (0.8-1.3 GHz) UHF receiver** In 2011 a new satellite was lunched by NASA, Aquarius, that uses a radar from 1220 MHz to 1280 MHz to measure the roughness of the oceans surface. During its 10-15 min passage over Effelsberg every 7 days the receiver will be most likely saturated. More information ​about the satellite and when it actually passes Effelsberg can be found on the following ​pages[[http://aquarius.nasa.gov/​|Aquarius Mission page by NASA]] and [[http://​www.heavens-above.com/PassSummary.aspx?satid=37673&​lat=50.52494&​lng=6.8827&​loc=100m+Effelsberg+RT&​alt=331&​tz=CETVisible passes over Effelsberg]]. +For more information ​visit our wiki pages [[ https://eff100mwiki.mpifr-bonn.mpg.de/doku.php?id=electronics:​index|'​Electronic department'​]]. 
-  * October 2012The 7mm secondary focus receiver is available againIt was fully tested, ​the calibration parameters from the receiver web page are still valid+ 
-  * July 2012The phase-switch off the polarimeter ​of the 2.8cm secondary focus receiver is repaired. To reduce polarimetric data taken between late August 2011 and July 2012 can be reduced using the "nos5" option ​in the [[information_for_astronomers:​user_guide:reduc_pointing|toolbox]].+  * November 25 2018Test Measurements for the Insight Mars Mission landing on Nov26 (R. Keller):

 +Last test measurement to check the system and monitor the RFI situation ​was performed successfully with the usual interferers that can be handled by the backendSee {{:​information_for_astronomers:​information_of_the_receiver_division:​operateure_wg_mars_rover_testmessungen_2018_11_25.pdf|protocol}} (in German).
