Volts on strong station tuned in is 4 volts when move off station I see the voltage slowly climb to 9 volts.
Current is .002 on station to .004 off station. Takes same amount of time for current to increase as volts increase.
Going from off station to on station the results of both readings is immediate.
Since I do see movement in the shadow graph it not likely to be mechanical.
If I use my signal generator as a source the current goes from 0 to .003 on/off station. Probably cause signal is stronger.
