Termination Unit MX-10080 ( )/GRC: The termination unit is used in place of a band-
pass filter when a channel is to be unused. It simplifies multiplexer operation because
it eliminates the need to tune an unused band-pass filter so that the unused filter
conforms to required frequency separation.

Band-pass Filter F-1482 ( )/GRC: The band-pass filter is a manually tuned VHF filter for
the frequency range of 30.00 MHz to 88.00 MHz. The band-pass filter has three tuning
knobs and three frequency dials. Each tuning knob contains a knob lock. Tuning is
accomplished by setting the three knobs to the desired frequency (indicated by the
frequency dials), applying rf power from the transceiver and tuning filter for minimum
reflected power and zero phasing error. The meter is located on the upper front panel
and is used to indicate forward power, reflected power, and phase error. A six position
meter function switch to the left of the tuning meter allows selections of these
functions for 6-watt or 60-watt full scale meter readings.
