If you are having trouble hearing [evening/night] (which makes more sense since you are asking about Tx power) I can only suggest a change in your local QRM level is causing trouble.
Locally I've noticed a definite step upwards in noise level at 2 meters starting at around 5:00 PM when neighbors return home from work and activate various unknown to me appliances in their home. I can see it on the SDR waterfall and also hear the increased noise ... without much change in signal strength from AO-92.
The electrical noise seems to increase an additional 50% during Christmas when the neighbors turn on their outdoor decorations.
