Hi Giuseppe,
You should see a change from the Fast to the Slow setting of the AGC corresponding to the speed of the S Meter update.? The value you are measuring in the S Meter function is the bias that is being sent to the two FETs that reduce the RF signal to the rig.? I do not know of a way to speed up the readings other than to maybe go back to the LM358 sensor and play some more with the capacitor value.
The other limiting factor is the speed of the Nano to read the value.? This may be the real delay in the update time.? The evidence to support this is the criticality of the capacitor selection.? The Nano is being pushed pretty hard in the ?BITX in all aspects of the capabilities of the device.? One of these days I may attempt to port the code to the Teensy 4.1 and use the Raduino that is supplied by Triumvirate Skonk Worx:
I have purchased the Raduino from them, I have the Nextion, just need to start working on the code.? That is not a small task (or else someone else would have done it already;-).
Hi John,
I like the idea of the variable resistor in place of the switch.? I will need to try it on one of my ?BiTX.
