A HF upverter added to the front end, and you are all set.

Very simple project, a cheap DIL crystal oscillator around 50MHz,
passive mixer with the ports switched around and you have a LF/MF/HF RX
from DC. Some front end filtering and Bob's your unc.

My first 2m QSO was made with a CB set feeding into a home-made
double-balanced diode mixer, and an ancient sig gen as the LO on 118 (or
maybe 177) MHz.
