433.500 to 434.000 MHz is the NB transponder tuning range, the anomaly shown is 500 kHz below the lower beacon, so at 433 MHz.

Details are in the image, see the signal around 433 MHz which I don't understand. Is this possible?

To be honest, I’m not a big fan of doing anything on a PC during a QSO, it should run with pen and paper and a transceiver, but we are still required to watch our own transmission. Sorry for going off-topic here, but a monitoring receiver (like a malahid) and a transceiver with a diplexer and isolator prevent me 1) from hearing myself when I transmit and 2) depending too much on a PC with its instabilities.

The best test is to simply call CQ and see who responds., no need to use the word "TEST", also "CQ TEST" has a difference meaning I thought in the sense that you are participating in a contest.

I got one at hamshop.cz and they responded within a week, Did this modification, the pluto adalm survived my mediocre soldering techniques.

It matters with the CW beacons what you measure since a SNR measurement is bandwidth dependent. So 2600 BW over both beacon carriers compatible to what you use in a SSB QSO?

I consider myself still fairly new in the qo100 community. One thing I don't understand are the RST reports, often it is a 59 or a 57 for SSB QSOs, but the best I can imagine for signal reporting is a signal to noise level that I see on the waterfall. For the speech quality I can indeed assign number between 1 to 5, but I don't do an absolute signal measurement at the antenna, there is still a downconverter there. I will just return a SNR from now on.

In my case up and down converter are GPS disciplined, the only thing that remains is a monitoring SDR pluto with an offset, and a icom 705 that has a 70 Hz like offset. You can use the websdr to discover you TX offset, modulate a 1000 Hz tone and see where it ends up.
