Hope this 40MHz EPSON TCXO (TG2520SMN 40.0000M-ECGNNM3) will stabilize the #AdalmPluto good enough for #QO100. Didn't want so solder on the Pluto boars, so I hope this small adapter PCB will work to feed the external clock input.

#Wireshark on #usb line to #AdalmPluto
Trying to figure out why output is so low -20 dBm
Analog Devices #cn0417 is indeed about 20dB difference ( the hold grey line to -40 is with that small power amplifier ).
The -60 is without, bare #AdalmPluto

TinySA Ultra measures -22 dBm on #AdalmPluto and 4.5dBm on #HackRF for 2400MHz.
The latter gets me over the satellite.
Still wondering if I blew Pluto final or it is a ( #soapy / #osmosdr / #QRadioLink ) software problem...
Gibt es eine 2m/70cm Dualband-PA für niedrige SDR Ausgangspegel?
Womit verstärkt Ihr Euer SDR Sendesignal auf 2m und 70cm für Phoniebetrieb?

How to augment RF amp / VGA so the Pluto can trigger the #dxpatrol upconverter?

Im Clubheim wird heute wieder fleißig gewerkelt. Dirk DK4DJ arbeitet an seinem "Pluto-TRX", einem Standalone- und Netzwerk-Transceiver für #QO-100 auf Basis eines #RaspberryPi und eines #AdalmPluto.
Lars DL1STO schließt langsam die Arbeit an seinem letzten Projekts ab. Sein "Übersetzter" von einem Magnetfeldsensor am drehbaren Antennenmast auf die Anzeige des Rotor-Steuergerätes bekommt heute sein finales Gehäuse.

Today instead of #gqrx i re-tried using #linhpsdr
The software immediately found the #AdalmPluto via #SoapySDR and showed the waterfall of narrow band #qo100 satellite. So far so good!
When pressing the TUNE knob the cli showed:
rxtx: isTransmitting=1
and on depress:
rxtx: isTransmitting=0
However I heard nothing on a real radio on the frequency. I tried usb and cw.
After this little TX test audo drops dead ( SOUNDIO backend PulseAudio Sample Rate 48000 ).
I find a TCXO for using with my #AdalmPluto
It's the TG2520SMN-40.0000M-ECGNNM0 (Epson)
it's little bit smaller than the original but it works perfectly.
Nice for using in my #ATV project (portsdown 4 from the #BATC ) and the narrow band transceiver.
And it work :) !
Today, i receive my new toy !
The Adalm-Pluto !!
He going to be a part of my DATV Project for 70cm to 13cm QO-100, now it’s time to research the Raspberry Pi 4 but but i’ve got no hope to find one 😔

SDR Toolkit Bends Weather Station To Hacker’s Whims
We probably don't have to tell most Hackaday readers why the current wave of low-cost software defined radios (SDRs) are such a big deal for hackers looking to explore the wide world of wireless signals. But if you do need a refresher as to what kind of SDR hardware and software should be in your bag of tricks, then this fantastically detailed account from [RK] about how he hacked his La Crosse WS-9611U-IT weather station is a perfect example.
Looking to brush up his radio hacking skills, [RK] set out to use the ADALM-PLUTO software defined radio from Analog Devices to intercept signals between the La Crosse base station and its assorted wireless sensors. He notes that a $20 USD RTL-SDR dongle could do just as well if you only wanted to receive, but since his ultimate goal was to spoof a temperature sensor and introduce spurious data into the system, he needed an SDR that had transmit capabilities.
No matter your hardware, Universal Radio Hacker (URH) is the software that's going to be doing the heavy lifting. In his write-up, [RK] walks the reader through every step required to find, capture, and eventually decode the transmissions coming from a TX29U wireless temperature sensor. While the specifics will naturally change a bit depending on the device you're personally looking to listen in on, the general workflow is going to be more or less the same.
In the end, [RK] is not only able to receive the data coming from the wireless sensors, but he can transmit his own spoofed data that the weather station accepts as legitimate. Getting there took some extra effort, as he had to figure out the proper CRC algorithm being used. But as luck would have it, he found a Hackaday article from a couple years back that talked about doing exactly that, which help put him on the right path. Now he can make the little animated guy on the weather station's screen don a winter coat in the middle of July. Check out the video below for a demonstration of this particular piece of radio prestidigitation.
Demodulating the waveform in Universal Radio Hacker.
While we often see the power of tools like URH brought up in talks, nothing quite beats following along with a step-by-step account of how somebody used software and hardware from the modern hacker's toolkit to achieve their goals. If reading this post doesn't make you want to finally pull the trigger on a cheap RTL-SDR and start cruising the airwaves, maybe nothing will.

Gestern hatte ich eine längere Jitsi session, um mit einem befreundeten Funkamateur herauszufinden, was genau mein #AdalmPluto für ein Problem bei der Soundausgabe hat. Es handelt sich jedoch wahrscheinlich um ein Soundlib-Problem von #Linux. Müssen wir weiter untersuchen. #hamradio
Stehwellenverhältnis #SWR der Antenne eines #AdalmPluto, gemessen mit dem #NanoVNA. Für den interessierten Laien: Der tiefste Punkt der Kurve ist der Frequenzbereich, in dem die Antenne am besten funktioniert. Hier grob um 800 MHz, das ist da, wo viele kabellose Kopfhörer empfangen. #hamradio
