should be very tightly bolted to the pipe. The ground wire should be soldered to
the copper ground clamp.
Radiola 26 will be operated in the manner previously described and
in addition, it will be necessary to regulate the "Station Selector 3". It will be
found that signals will come in as usual no matter what the setting of "Station
Selector
3" may be, but that the signal intensity can be increased by the proper manipu-
lation of "Station Selector 3". It is suggested that the following method be
employed for tuning in a station: Operate "Station Selectors 1 and 2" and tune in
a distant broadcast station. Then manipulate "Station Selector 3" until the signal
has been increased several times. Unless the antenna is changed, it will be noted
that a definite relation exists between the settings of "Station Selectors 1 and 3".
