Filter and BFO Settings (C A L F I L , Table 5)

: Before recording filter/BFO data, switch to any of the lower bands

(160-17 m) so LSB/USB settings won't be swapped in CAL FIL. Connect the internal frequency counter cable to TP2
(BFO). To access filter and BFO settings, tap M E N U , scroll to C A L , hold

E D I T

to access the parameter, and

change it to F I L . Hold

E D I T

again to activate the C A L F I L function. Record filter bandwidth settings (e.g. 0 . 7 0 )

for each mode and each filter. Cycle through the modes by tapping M O D E and holding

C W R E V

when appropriate;

filters are selected using X F I L . (RTTY mode, r , and RTTY reverse are only available with revision 2.00 and up
firmware. The associated secondary menu entry, R T T Y , must be set to O N .) After all filter bandwidths are recorded,
tap B A N D - followed by D I S P L A Y to show the BFO frequency. Record the BFO frequencies (e.g., 4 9 1 3 . 1 0 ) for
each mode and filter, as you did for the filter bandwidths.
