AM AGC suggestion

[spchn]

Hello, genuinely love the firmware but the AM fix simply doesn't do it for me. Sometimes I get stuck at strong signals even when they are gone or get a lot of hissing. That's where I stumbled upon AM AGC fix from Kamilsss fork of egzumer that makes AM fix useless and from that I found Robby69's take on that AGC which got rid of the extreme gain on AM that made the scans stop sometimes.

i think it could reduce some Eeprom memory weight of this FW and improve AM even more :)

Hello,

I’m moving this issue to discussions.

Did you say you sometimes get stuck on strong signals? Was it when using the spectrum analyzer? Perhaps you should play with the LNA, LNA, PGA and IF parameters? I have no problems with AM demodulation myself.

About the firmwares you mention, I don't know them. I therefore encourage you to continue using these other firmwares if they give you satisfaction.

Finally, I don't see how such a correction could reduce eeprom memory usage. The eeprom memory is only used to store settings, calibration data and memory channels ;) The eeprom is not used to store firmware. This is contained in the microcontroller's internal flash memory. And today, there's no more space available.

It was when using spectrum analyzer. I tried to move them but it "flickers" up and down or changes the values back to insane boost.

And for the memory I'm sorry for my misunderstanding of the way firmwares work. I thought that the am fix would introduce more memory usage and getting rid of it altogether could help

Removing the AM fix would indeed reduce the firmware size by a few bytes.

But what you'd gain in space, you'd lose in quality — and you'd probably be the first to tell me that AM demodulation has become horrible 😄

If Kamilsss removed it (as he mentions in his README — I just checked), it's likely because he replaced it with a different approach (I haven’t looked into which one). And there's no guarantee that this alternative doesn't actually use more memory.
