Alternate method to enable TV mode

My IC-7000 has an additional set of solder pads next to TV diode D2154.

The solder pads are in the shape of half circles connected by a thin printed trace. The thin

pc trace can be easily cut with an exacto type knife.

If present this method eliminates unsoldering the small surface mount diode, furthermore,
the TV function can be easily disabled by bridging the half circles with solder.
