How hard for a spy to receive 6855 or 8010 kHz?

Could a spy modify an AM radio by adding a few capacitors?
Not well, but where can you buy an AM radio or capacitors anymore :-) ?
Or was this some hypothetical 1940's time-travel question?
A $10 super-el-cheapo pocket SW receiver from a discount store does
just fine for picking up numbers stations. Some but not all number
stations are CW or SSB and you'd need a BFO which is one step up from
the super-el-cheapos.
