Description: This video shows how to install an optional narrow CW filter in the Icom IC-703 transceiver, then runs some tests to show the operation and effectiveness of the new filter in dealing with adjacent signal interference. Here is a link to the filter I used in this video: inrad.net/product.php?printable=Y&productid=130 0:00 - Introduction 0:24 - Icom and Inrad Filter choices 1:25 - Begin installation 1:53 - Main board removal 3:10 - Install filter 4:10 - Re-install main board and reassemble rig 4:55 - Configure rig to use filter and verify 5:33 - Listen to the effect of the filter 5:51 - "See" the filter shape using an FFT 7:00 - Listen to filter effect on two closely spaced signals 9:00 - FFT of filtering of closely spaced signals 10:48 - "On-air" demo of filtering away close-in signals 11:06 - Closing
