the VFO of BITX20 has an interesting story. it is actually my inductancetoggle quoted messageShow quoted text
looking at the VFO, if you removed the trimmer, it becomes a test
oscillator that iuse at all times. this idea is due to W7AAZ (Bill
you can quickly assemble a frequency counter like one of the several shown
To measure an inductance, solder the the coil into the VFO circuit,
measure the frequency. The capacitance is well established, from there
calculate the inductance.
i had written a few lines code in C (i think it is posted it its entirity
on rec.radio.amateur.homebrew). that helped me calculate it quickly.
the test oscillator also works as acrystal oscillator (solder a crystal
in place of the coil) to measure and match the crystals.
