I really appreciate the remake of the the video. Thumbs up therefore. One thing should be noted: The signal strength is a voltage ratio and the S/N indication is a power ratio. Noise power depends on the bandwidth, so you can increase the S/N by narrowing the AM bandwidth on the receiver. This is the reason, why you can select the AM bandwidth at good receivers.
Gilles, thank you for the re-explanation. These S/N numbers also help me when comparing two different antenna inputs into my PL 330 to determine which one is giving me a better signal.
The S meter S1-S9 - actually represents a certain amount of dB; nearly 6dB per S value above and below S2-S3. The dBµ theoretically tops at 99 - S values are: 1 - Faint-signals barely perceptible (-14dB) 2 - Very weak signals (-8 dB) 3 - Weak signals (2dB) 4 - Fair signals (4dB) 5 - Fairly good signals (10 dB) 6 - Good signals (16 dB) 7 - Moderately strong signals (22 dB) 8 - Strong signals (28 dB) 9 - Extremely strong signals (34 dB) The second pair of numbers SNR --- should be MINIMUM 8 Value to enjoy a "Fair Signal" (tops at 35).
Thank you for your vídeos. Could you please make a video explaining how yo send a reception report to a Broadcast station (for example BBC or Radio Exterior de España? Please, explain if you send a QSL card or a letter, and how to indicate the Signal. I do not know if SINPO Code is used. Please explain how yo determine the SINPO of a Broadcast station if used. Thank you very much
Dumb question... if VM stands for manual and VF stands for frequency. What does the “V” stand for? Sorry -this is not quite related to your video tonight. But wanted to ask...

Thank you Gilles, I've been wondering how to interpret the numbers, now I understand. Enjoy your channel a lot, cheers!

That is helpful information!
Thanks for the clarification, Gilles; I certainly have a much better understanding of how these things are to be interpreted.

Tell something about noise ratio,,,please
Excellent explanation
I got it but this was a little more clear.
Thank you!
Thanks for the explanation.
Excellent explanation. So when I'm tuning and I get a reading like 59-25 but I hear nothing. What action should I take?

What radio is displayed in the video Gilles ?
Tecsun PL-990x

I think VM is VFO-Memory Channels and VF is VFO Frequency Tuning.
