This is a bit silly, but I could simply not remember: was the 100’s UHF or VHF? 400’s UHF or VHF? I sat down one day and thought of something to remember it by:
1 Very Hungry Fox ate 2 Much
1 (100ish frequency), Very Hungry Fox (VHF), 2 Much (2 meters).
I printed the fox image I created in Gemini’s Nano Banana and put it in my shack.
