TS440S mod for increasing sensitivity on the MW AM broadcast band:

(Removes MW attenuator pad). The TS440S has an attenuation pad hard wired on the spectrum between 500KHz and 1600KHz. You

can open up sensitivity by removing it. On the RF unit board, clip a lead on R13 68 ohms), clip a lead on R14 (68 ohms), and solder a

jumper across R12 (220 ohms). These are under a shield held down by screws on the RF board.

I've noticed no intermod problems and only the strongest stations (above S + 40) overload (which can be solved by using the front

panel attenuator button).
