[ARC5] Heath GDO People

[Richard Knoppow]

    On the size of the coils of any dipper: its possible to use 
link coupling where space is limited. Instructions for this are 
in at least a couple of GDO handbooks. Can be done with stiff 
wire or in other ways.
    I think GDO's are sort of forgotten instruments. They are not 
precise but can do things its hard to do otherwise such as 
injecting signals into transmitters or receivers. Useful for 
adjusting new equipment and design of output circuits, etc.
