Hi Ken
That coil is a .35 uh coil, the designation in the manual is
incorrect. Its resonant with C205 at 21.0 MHz
I just got a similar slug out of the junk box and wound
it myself dipping it on the bench with a 180 pf mica and
soldered it in, its not that critical, very low Q.
You could probably wind one on a T-50-2 (red) toroid
core and be close enough.
