+It's also simple to control the Inrad filter with the ATTN switch if you don't use that function.
+Here's what you do:
+Skip Inrad's instructions numbered 18 through 24.
+Set aside the cable/connector provided for J4 on the Inrad board, you
+won't need it.
+Take the cable/connector provided for J3 and tie the lines together,
+then
+add an extension so the wire will reach up to the front of the Omni,
+plus 4 or 5".
+Locate the 3 pin white connector labeled 18, at the left front side of
+the Front End Board, as viewed
+from the front of the Omni.  Cut the middle wire going to the connector,
+leaving a few inches
+behind on the connector in case you ever want to reconnect it.  This is
+the line that goes to the Attn
+switch.  Connect the lead from Inrad J3 to the end of the line going up
+to the front panel Attn switch.
+Tape up the end still attached to the connector.  Set S1-S4 on the Inrad
+board to ON.
+That's all.  Inrad now switches in and out with the Attn switch and the
+led shows when Inrad is switched in.
+All Omni filter switches are unaffected.
