Capacitors on Xtal side are:
C1 Beehive trimmer
C2 100pF 500V silver mica
C3 0.02uF 500V ceramic disc.
No C on xtal side of the Paraset except the gimmic wire wound couple times around the anode connection.
I am using these valve TX and the "cat meow" effect occured with the Scrounger (First one I built) and when I tried to use a HC49 crystal with a small lamp in series to reduce the current flowing through the crystal the meow was the result. The same settings with a HC6 4MHz crystal had just worked.
