F. NOTE On earlier models of the CE-7 the IF position ON switch is part of the r. F. GENERATOR LEVEL control.
d. 3.4.6 Antenna Installation Remove the telescoping antenna from the front cover of the C E-7. Insert the telescoping antenna into the ANT. connector on the RF plug-in used and turn the connector collet until finger tight. NOTE Be careful to install the proper frequency crystal for the desired operating fre quency. The correlation between cry stal frequency and operating frequency is shown on the box in which the crystal is packed. When removing the telescoping antenna from the ANT.
SECTION 4 CIRCUIT DESCRIPTION The 10- MHz signal (± frequency e r r or ) is fed to the Second IF and Discr irninutor board where it is amplified a nd m ixed with a 9.9-MHz signal from the Multi-Osc illator board to form a second IF"and 100 k Hz (± frequency error). This second-IF s ig nal is amplified and applied to the frequency error detector. 4.
A signal generated with the CE-7 is derived from the same sources as the LO. signal with which an incoming signal is mixed to form the first IF and to determine fre quency error. Because there is always a 10- MHz difference between the sele cted frequency and the LO. signal, this 10-MHz difference must be removed before the LO. signal can be used as a signal-generator output of the selected frequency.
