Have a manual from the "BAMA" manual web site.

The pages there mention "Voltage Chart" but it's not included in pdf
Contacted keepers of BAMA and indication was all that was available, is
posted.

Does anyone have a copy of the Voltage Chart?
if not and you own RF103 - any voltage measurements you've made on the
variable resistor on tunable coil (Right side coil) ?

Working through Diff Amp circuit that drives servo at the base of tunable
Coil
I've cleaned and checked variable resistor that is used for position
sensing - that seems fine, seems....
