Jumpers for joy

As with the TS-2000, something special has been provided for both the BPF ATT in the BC band and the regular ATT:

The BPF has been equipped with an ATT in order to cope with powerful local broadcasting stations in the BC band. However, a jumper can be used to switch from NORM to DX, bypassing this ATT and raising sensitivity by about 20dB.

The ATT accessible from the control panel defaults to 12dB, but by removing the CN4 jumper it is possible to increase this to about 20dB.
