@0zelot @thasti @Ssaev @DMdsW @dohvera it's lunchtime? :P

@luciangasparini @oshpark I used MIC5233-3.3.

@eah_satcom @oshpark Which 3.3Vdc voltage regulator was chosen on the circuit? I haven't found it on the BOM.

beautiful @oshpark PCBs for phase locking of Octagon PLL LNB for low cost and rock stable 10 GHz #hamr reception

thx for your feedback 😊 now the documentation is also in english available: loetlabor-jena.de/doku.php?id=en… (thx to @thasti for new wiki plugin and translation)

@eb3frn @oshpark I have uploaded some precompiled binaries for 27 MHz and 25 MHz at the link above.

@eb3frn @oshpark Yes, it's simple as changing a define in the firmware. A compatible 25 MHz VCXO is the Kyocera KV7050B25.0000C3GD00.

Step 3: unscrew with Torx T10 and voila! (other side the same procedure)

Step 2: remove the coating

@lmoline @oshpark Try google tranlsate, it performs very well: translate.google.com/translate?hl=e…

@eah_satcom @oshpark Now if this info could be in English. Thanks so much for your post!

@DB9MAT Finally managed to phase lock the #PlutoSDR to an external 10 MHz reference! 😃 I populated 100 pF at C124 to scale the 3.3V CMOS Output to 1.3 Vpp Input Level Requirement of the @ADI_News AD9363.

@eah_satcom What is the BNC connector in the front? Did you manage to add an external reference?

@coastal8049 @NASA confirm IMAGE at 2272.5 Mcs with ~30dB S/N @ 500Hz RBW with 4.7m Dish

FLASH!! @NASA's cranky IMAGE satellite is back!! She started experiencing very minor eclipses for the first time since she faded away in late February and today her signal is back LOUD and clear! Her battery capacity must be very low as the eclipse only lasted about 9 minutes.

Hey @NASA, do you already have a date for this year's @spaceapps? :) Would be nice to bring #spaceapps to #Jena this year. What do you think? Shall we? @DLR_software @esa @DLR_de @JenaerTweets @REXUS_GAME @eah_satcom @OffenesJena @HackspaceJena @DGLReV @UniJena #myfirstTweet

Dish is now on top of the tower 🙂
