7.1  piWebCAT - Database table - lookup

The lookup table is used for the numeric value presentation from a slider when there is

a non linear relationship between the CAT value and the displayed value.


Example from Yaesu FTdx101D CAT manual:

The Fdx101D has different values for SSB and the other modes.
The slider table lookup field can have values
 N, Y or M.   (N = no lookup)

If slider.lookup = Y,  then the lookup table entries must have mode = Y.

If slider.lookup = M, then the lookup table entries have mode = current operating mode

which is the caption on the mode button.


For IF width, slider table lookup = M.
We have to create separate lookup table entries for each operating mode.

I have separate identical LSB and USB sections in the table (not  SSB) in order to match button captions,  LSB and USB.

The slider has single max and min settings.

These are set to 1 and 21.  Lookup entries for CW, RTTY, PSK are extended with 19, 20 21 set to 3000Hz.

The above shows a section of lookup table in piWebCAT's editor.

I have in total:

  IFWD   LSB    21 entries  CAT values 1 to 21
  IFWD   USB   21 entries   CAT values  1 to 21

  IFWD   CW     21 entries  CAT values  1 to 21       CAT value 19 to 21 added in as 3000Hz

  IFWD   RTTY  21 entries   CAT values  1 to 21       CAT value 19 to 21 added in as 3000Hz

  IFWD   PSK   21 entries   CAT values  1 to 21       CAT value 19 to 21 added in as 3000Hz

Any other mode uses the LSB calibration


Setting mode = X makes the entries applicable to any mode.
