I had the curiosity to do some tests transmitting and receiving DMR DMO with an unmodified #plutosdr

Normally DMR in repeater mode requires establishing a time base from the BS transmission in order to fit into one of the timeslots.

However, in DMO mode, there is no such requirement. When starting a DMO transmission, every terminal establishes its own time base, and the receiving radio must synchronize to it.

So DMR in DMO mode can work fine with the Pluto.

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

#hamradio #QRadioLink

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.
