Getting your ham husband (or boyfriend, father, etc) a ham radio-related Christmas gift is challenging. Don't try to buy him a radio - half of their fun they have with the hobby is researching radios to buy. Instead, get him a amateur radio related gift that he would never buy for himself.
There's a great T-shirt on Amazon that says "HAM radio operators do it with greater frequency". It's under $20 and available in lots of colors. You can buy it here
