MAIN RECEIVER 2ND AND 3RD IF FILTERS

A total of 5 optional crystal IF filter units can be in- stalled in addition to the factory-installed filters (see the table). Contact your dealer for pricing, availability and ordering. These filters include small boards with connectors, so no soldering is necessary for their in- stallation.

Important! After filter installation, front-panel se- lection is not possible until individual filters are enabled via menu programming (menus selection 5-0~ 5-8). Re- fer to the Menu Programming chapter and enable the optional filters after installing them.

Filter Installation

rDisconnect all cables from the transceiver.

rReferring to Figure 1, remove the four screws (ð) on each side of the transceiver, and the seven screws (ž) from the bottom of the transceiver, then lift off the bottom cover.

rReferring to Figure 2, remove the six screws (Æ) from the top panel. Pry the top cover open and dis- connect the speaker cable from the speaker, then lift off the top and side covers.

rOn the underside of the transceiver chassis, locate the IF UNIT. Referring to the drowing below, deter- mine the location of the filter(s) you are installing.

rPosition each filter so that its connectors are aligned with the mounting pins on the board, and push it into place, so the nylon mounting tabs “mushroom” through the holes and lock the unit in place.

rConnect the speaker cable to the speaker on the top cover, then replace the all covers and screws (unless installing other options now). Refer to pages 101 and 102 of the Menu Programming chapter to enable newly-installed filters.

SUB RECEIVER CW NARROW FILTER

The optional YF-115CCollins mechanical filter (500 Hz BW) is available for the 455-kHz Sub Receiver 3rd IF for enhanced reception. Only top cover removal is required for installation.
