When doing shortwave listening, I always want to be able to check the current time in UTC.

A Ham radio clock based on ESP32, showing UTC and local time, HF propagation conditions and local weather. It uses wifi and NTP to keep the time, and downloads XML from hamqsl.com for propagation conditions. Local weather comes from my shed over MQTT.
The top has a hole that takes a rotary encoder to select various screens. You may need to ream the hole a little for whatever encoder you fit to yours.
I used supports for the large gap for the display. You may be able to get away without it, depending on your printer.
