Request to include CW Mode in next firmware version

[paolettopn]

Hi OM,
I've been using the ESP32-SI4732 Radio Receiver for a few days and today I installed the new firmware version 2.14 (2025-05-06).

I would like to ask if it is possible to insert the CW Mode among those already present in the menu, so as to be able to listen more easily to amateur radio stations that use this mode.

I am very satisfied with this project and with the operation of this small receiver and (for now) I have not found any problems with its operation.

Hello, Paolo!

Sorry, but it is unlikely that I will add CW mode.

The minimal bandwidth supported by SI4732 receiver chip is 500Hz. This bandwidth is already available in LSB and USB modes, and it makes very little sense to add another mode with the same parameters.

So, just use LSB or USB and set the bandwith to the most narrow value

Hi max-arnold, Another inquiry regarding about adding CW mode ... many hams that I spoke to would be interested in a CW mode option. I understand it would be redundant with SSB mode, but what about a CW mode that enables 500 hz bandwidth when selected? Just a thought ... Thank you for all the work that you're putting into the firmware. Tim

Many thanks for quickly response.
