Minimalist Dip Meter
Minimalist Dip Meter Circuit Diagram. In days gone by a radio amateur always had a dip meter close to hand in his ‘shack’. Now that people can afford oscilloscopes, the poor old dip meter has lost its importance and is frequently no longer to be seen. Actually this is a shame because many tasks are much easier to carry out with a dip meter. Anyone who’s interested (perhaps the second time around) can easily build one rapidly with this very simple but adequate circuit. The interesting question is namely what do you actually need from a dip meter? Minimalist Dip Meter Circuit Diagram A visual display of the dip? Nope, the ‘scope can handle that task. A large frequency scale? Not necessary, as you can connect a frequency counter for this. A selection of coils? We don’t need these because we can use a jumper to change range (no coils to lose any more!). The sensor coil L1 has ten turns and is wound using an AA-size battery as a former. This coil will allow us to over the ...
