When I was at the "Dag van de Radio-Amateur" or "Ham Radio day" in the Netherlands recently, I've met this interesting Ham Ha, PA5HE.
He's been busy converting several old CB radio's into Ham Radio transceivers for the 4 meter or 70 MHz band.
Some are really smart where he'd actually replaced the existing 7-segment display with a small OLED display capable of showing the full digit frequency.
Isn't that cool ?!!
It's in dutch so for the non dutch speakers not all info might be clear, but I'm sure a handy ham can find enough to get inspired:
