This gives the schematic and lots of data in Japanese.

All RF circuit inductors could be replaced by small  (T50-6 or T37-6) yellow toroids and variable caps.

    Just wondering if the vxo/doubler in this little rig will pull down to the 28.500 activity window.

    More of a chance of contacts then.
