500pf variable capacitors and a e roller inductor the variable capacitors with 3mm plate spacings are well capable of withstanding voltages of several kilo volts
Two versions of the SPC antenna tuner
The nominal values from the article are: C1, 200 pF; C2, 200 pF per section; L1, 28 microhenries, roller inductor
Using Auto-Tuners
When using an autotuner you donÂ’t necessarily have to use a resonant length of wire. In fact if you wish to use one for multiband operation it may be best to pick a length of wire which isnÂ’t resonant on any of the required frequencies
Z Match A Drop-Out Region
The Z match tuner can be resolved as a simple L network of series capacity and shunt inductance combined with an output coupling circuit

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
RF Inductance Calculator Mean diameter of the air core coil, measured from conductor centre to conductor centre include the wire insulation thickness, if any
