Hi;
Question : Optimizing the minimum capacitance of the input of a PI filter
circuit including available stray capacicitys.
I have to now what the minimum capacitance is,of the input circuit of a
homebrewed amplifier PI-filter system.
Can I measure this value with the vacuum capacitor already mounted and
connected on his place into the input of a PI-circuit.
Meaning is to now what my obtained minimum capacity is of my builded PI-filter
inclusif the obtained strays in the RF case.
It is even possible that I can not reach the PI-filter calculated minimum C
values from the PI tables for the 28 Mhz band !!!!
Maby my strays togehter with the minimum value of my input vacuum C is to high
to obtain resonance at higher bands ?
I look forward es 73's Jean ON4AEF.
