[TenTec] INRAD 2.8's and RX Mod?

[Paul Christensen]

The Omni Six (Six +) receive mod can be accomplished by making the following
changes to the IF/AF Amp Board:

1) Replace C3 & C29 with 0.01 uF film capacitors (>50 VDC).
2) Replace R38 with a 680K-ohm resistor.

Depending on the vintage of your Omni Six, these components may be
surface-mount types (SMD).  Mouser is a great source for these components:

To take full advantage of this mod, the 2.4 kHz filters in both IF slots
should be changed to the INRAD 2.8 kHz series.
