Transmitter output measurement is done using the TinySA spectrum analyzer.
Radioberry hat covers 10/15/17/20/30/40/60/80/160m All Band, All Mode HF SDR QRP Transceiver - by Johan, PA3GSB for the Raspberry Pi 4B running PihpSDR software/app by John Melton, G0ORX.
This is a step-up from the popular uSDX+ SOFTWARE DEFINED RADIO.
Probably a step lower than the Hermes Lite-2, because it's still a half-radio. We still need to build a BPF, LPF, TR relay switching, Pre-amp, and PA - to make it a complete Transceiver.

lots of harmonics in those tones, BPF/LPF needed!

Cool project. Looks cool, it's a system I don't have any idea about but still looks nice. Have considered getting into this just for the tinkering. Have a nice sunday

@PremMenon 9 месяцев назад

All the information is freely available on GitHub. Just google "Radioberry". Thanks for checking it out. You too have a great Sunday!

Excellent video, thanks do you think a Pi4 1 Gb work with it?

@PremMenon 8 месяцев назад

Thanks Ray! 2GB is known to work. I'm not sure of 1GB though.

I wonder if this will work with a pi5? Liked Subscribed 😊

Ill wait until something is available for the pi5

Thank you 👍

@@KA4UPW might as well. It's a rather expensive project. FYI.

Could you please tell me what's is the the max TX power output on the Radioberry?, some people say 4dbm or 2.5 mW, some say up to 100 mW. Couldn't find this on the internet. Thank you

@PremMenon 3 месяца назад

I have two Radioberry cards. One gives an o/p of 20dBm, and the second gives about 17dBm.

@Flagrazi 3 месяца назад

20 dbm? Where did I get the 2.5 mw from? Thanks

@Eugen963 6 месяцев назад

What's Radioberry's output in mW?

@PremMenon 6 месяцев назад

In my first TX test (CW-tune mode), I saw an average of 1mW output across the HF bands into a dummy.

@chestercorpus1392 6 месяцев назад

How can it be just 1mW when the tinySA measured 4dBm-5dBm magnitude of the fundamental frequency. And on the upper left part of the tinySA's screen says "Atten! 28dB", does it mean that the tinySA's input attenuator is set at 28dB attenuation? If so, then the Radioberry's power output should be at least 1 Watt!

@PremMenon 6 месяцев назад

@@chestercorpus1392 Thanks for your input. It's helpful, indeed. I'll measure again to verify/confirm that. Currently my Radioberry project is QRT because of upgrades.... work in progress. Will definitely measure that again.
