@solipsism_2 Hello, I have such an antenna in good shape for sale. If you are interested then please send me an Email and we can discuss it. Kind regards Matthias DD1US

Desperately need some sort of phase array antenna for relatively "cheap" What are good suppliers? Also I would like to know how much of a no-no the quote was like OPSEC wise (I think OP is in Xinjiang). Probably nothing, but would appreciate it if you guys tell me just in case

@ZhaoFen37759626 Dear Zhao, very interesting. Please keep us posted on your investigations. Kind regards Matthias DD1US

Weather radar antenna panel found at a garage sale, 28 inches, gain 34.5db@9.4ghz. I'll be measuring this antenna over the weekend to see if it works at 10.5g

@HHolsink @geekc0der Hi Hans, In case you know the people running this company: please tell them, that AMSAT-DL requires to operate full-duplex when using QO-100. I think it is unfair making money by selling a commercial product and violating the rules of the satellite operator. Regards Matt DD1US

@geekc0der Nope! No need for. No doppler on QO100. Convenience of just talk to what you hear made this decision. Rover/holiday station contains just small box and portable 2m trx.

Nice present with Xmas. Satrover all-in QO100 transverter now in the shop. No need for internet or computer, drive it with 144 MHz tranceiver. (IC705 or ft818) hamshop.nl/satrover-qo100…

@SP9DLM Darek, congratulations to your new radio. I recently bought a "battery eliminator" for my Yaesu handheld on Ebay. It costs about 12 Euro including shipping. Maybe you can find one also for your radio!? Kind regards Matthias dd1us.de

I became the owner #Kenwood #THD7 . It has a damaged battery. I am looking for a replacement or possible repair. Whether to buy a GPS module or make it yourself. what do you advise? #aprs

@otti_sat @f4hwn Sehr schön, habe mir auch einen M5Stack bestellt.

Thanks to @f4hwn the little M5 Stack coupled by Bluetooth to my IC705 now displays my 10GHz Transverter frequency and meter screen plus full spectrum on the 705. This almost converts it into an IC905 :-)

@ZhaoFen37759626 Where are you?

It's beautiful, it's cool... It's just bad Internet reception

@vikingrover Hi Tor, beautiful pictures. Are you still planning to activate QO100 from that place? Regards Matthias

@uhf_satcom @aang254 @otti_sat We missed you, hopefully you can come next year

@aang254 @otti_sat Nice! Enjoy it chaps, hopefully you will find some excellent bargains, please post lots of photos ;-)

Catch of the day from #hamradio flee market in Friedrichshafen. Some microwave candy. I left some more to buy for tomorrow:-)

@aang254 @otti_sat Great, thanks for coming to the QO100 User meeting. It was great to chat with you.

@otti_sat Ah, I did see those earlier! However this year there doesn't seem to be as much diversity as last year... I did manage to find some Ka-Band parts etc however.

@otti_sat Nice Otti, it was pleasure to see you and some others there. I also got some nice parts at the flea market including a septum feed for 9cm band

@aang254 @Aaronia_AG @SDR_Radio Excellent, congratulations to your license. Maybe you will get the callsign in time for your Trip to FDH. I am looking forward to see you there. Don't forget to register for the QO-100 Usermeeting on Saturday evening. Registration is free, you can find the link at AMSAT-DL site

@DD1US @Aaronia_AG @SDR_Radio Definitely! And I (finally! Long story...) am a ham. Just waiting on a callsign.

Little test with @Aaronia_AG's Spectran this morning @sdr_radio, checking out FMCW radars @ 24Ghz, 245MSPS, with a "white box" down converter. Works perfectly :-)

@aang254 @Aaronia_AG @SDR_Radio Very nice!

@ilovegarick @TubeTimeUS Yes, screen cleaner

@TubeTimeUS Screen cleaner?

what is this thing?

@remcodenbesten Sorry, meant to write Remco not Emco

@remcodenbesten Hi Emco, do you need more of them ?

144 MHz rig from the 70's. The stickers were obligatory to identify them as 'AM zender' (AM transmitter, AM = AMateur). #hamradio

@DK9JC @IbanHoyos @M0SKN_SA5IKN @ok1cdj @CT1FFU Yes, however station working you needed extremely high power as your Sensitivity was low. IMHO not a good idea!

Worked dishless via #QO100 🛰️ with bare DXpatrol LNB for RX: #R5DT #SP2HPD #DD6ZV and @IbanHoyos #EA1ISE. TX was my wifi panel 15.5dbi linear (12.5dbi RHCP equiv) cc @M0SKN_SA5IKN for the idea, @ok1cdj doing it also and @CT1FFU tu for lnb, gpsdo, rx pll box and upcvtr etc. #AMSAT

@st2nh Hi Nader, I am glad that you and your are now safe. Let us know if/what we can do for you. Kind regards Matthias DD1US

@engineers_feed 156

Mathematical puzzle. Find the missing number.

@2m0sql @amsatdl Send me an Email and I will check whether I might have something suitable for you.

The @amsatdl docs for their QO-100 upconverter suggest putting a 2.4 GHz ISOLATOR in line, however, I need help finding a suitable one on eBay that isn't stupidly expensive. thoughts? #hamr #amsat
