hum, from the ckt diagram I would expect the lir 2032 to actually be recharged during power on events. I don't suspect your rig to be powered down long enough to drain the drain the battery.

Thanks for watching my video. You might be right, but the reason why I don't expect LIR2032 to be charged during my normal use of the radio (DC power supply on for a few hours on weekends) is because of the 3.3k resistor in the circuit, limiting the current 100 micro Amp only. I'm planning to discharge an extra LIR2032 that I have, down to somewhere around 2.5 V and then supply DC 3.3V with 3.3k resistor in line. I'm gonna leave it ON for several hours and see the results. You may already know the result, but I need to test it to know. I will share the result later for those who are curious like me. Thanks again and 73

I downloaded the time adjustment software from the icom website and each day I switch my radio and pc on it auto sets the time. Simple.
