#adalmpluto — Public Fediverse posts

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.

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?

#hamradio
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 :) !
