Default Howes DT1 fine tuning board.

hallo,
there was an optional board available for vfo fine tuning,
module dt1 ,
i have the info and schematic about it and will construct it myself, also were its connections are,
however , the instructions stated : dont forget that when you make te connections to the main tuning capacitor, you still have to connect the capacitor to its connection point on the main pcb(receiver/vfo etc)
wonder if any one nows were the connection point lays on the main pcb dxr20,
or has any info about the fine tuning optional board and its connections.
regards carlos on6cn
