This tag pertains to the configuration as purchased. It is for the 
factory in case the customer buys another receiver and wishes to to be 
the same as previous equipment.

This switch aligns the IF filters installed with the front panel 
display.  Unless the filter compliment on the Filter board is changed 
there is no need to change them. If you change the switch positions then 
do a CPU reset you will see different filter Bandwidths displayed. Since 
they are crystal filters, nothing changes except the display

Both the Noise Blanker schematic and the Syllabic squelch schematic are 
available but I don't have them at home.
