If a channel kit with two extra-band crystals is wired where the crystal used to be, that would explain it. Typically you were told to remove your channel 1-40 crystal and install it on the kit with the upper band crystal and lower band crystal. Two wires went from the kit to the circuit board pads where you removed the factory crystal.

The most popular of these by far was called the "Expo 100" or just "Expo" kit. A whole list of different versions were sold to match all the wacky crystal setups found in older radios. They were discontinued some time back, but an outfit called "lescomm" sells a modern-day version for a handful of different radios.

This crop from your pic shows the oval outline of a quartz crystal, labeled "X3".

A missing quartz crystal. A channel kit will have two wires, one of each soldered to two foil pads underneath this crystal outline.

If you find no wires, what you need is the 11.3258 MHz crystal that someone has pirated from this radio.

Or an equivalent replacement.
