I was able to dig out and get working my old Radio Shack multimeter that has capacitance and it reads 0.1 nf. I measured a bunch of other caps to ensure the meter was working. And to answer Mike's question, There is an added 1M ohm resistor from the grid pin 4 down to the other side of the antenna loop (parallel with the loop). These two components are not on the schematic. The radio functions well without this ceramic cap and a jumper in place of it. George
