Hope to add Step selection in SSB mode，This will make the 4735 much easier to use。Thanks！

Hi ralphxavier！Thank you so much for sharing such a cool project.I met a problem.
1:When the volume is 0, the speaker still has sound output.2:The FM frequency range of the new firmware does not start from 67Mhz.The shortwave frequency will be offset by about 1K,Maybe it's a problem with my hardware。Anyway, thanks again！

Hi，Thanks for sharing such a cool radio. I made one based on the data. It is now my favorite radio, but I found a bug that bothers me.
Switching from AM to FM mode, the step value is no longer 100K, which will cause the FM frequency to fail to align with 100K, and reception problems

I assembled a receiver with a SI4732A10 chip. I connected a separate headphone amplifier to each of the pins 1 and 16 on the chip. The amplifier is tested and each channel works separately. But on the FM band I only have mono mode (I don't hear stereo in headphones), while the TTGO screen shows that stereo is working. I have tried firmware V3 and V4.1 and there is no stereo anywhere. Is this a problem in the SI4732A10 chip or in the firmware? How it can be fixed?

          Hello ralphxavier!Is it possible to add preselection Store, to store any Stations in SSB?73

On some occasions, the SSB patch fails to load. It's happens intermittently.

Hi.
I've tried to compile your sketch for a ESP32 Lilygo but I get several errors:

Are there something wrong with the libraries?
I've update TFT_eSPI to version 2.4.79. Which version do you use?
Thanks for your help.
Best regards.
