Hi folharinOriginally posted by folharin View PostI did all the franco circuits. Here in Brazil it doesn't work, not even in the test field...:n?o n?o::carranca:
How old is your test field?
What indication method did you pick up for your receiver?
Have you tested a voltmeter in place of leds?
Can you share how did you confirm that your device is built successfully?
Do you own an oscilloscope?
Thanks

Hi Mr Franco
I created version on 20Mhz (crystal 14Mhz). How can adjust to pot 1,2,3 and c10 to get the maximum performance to one harmonic?
I have not oscilloscope.
I can measure volts at the output?
The value i have to get?
Thank you in advance.

Measurements must be made at the sensor stage output (direct voltage). C10 needs to be adjusted for maximum output. Obviously you have to follow the instructions of the helps, no signal must be there without the quartz and others.Originally posted by tasmen View PostHi Mr Franco
