6.7. Lost and destroyed bands

Bands coded as L (lost) or D (destroyed) use a special short record with these fields:

Lnnmmddssss
Dnnmmddssss

where:

L

denotes a lost band.

D

denotes a destroyed band.

nn

is the last two digits of the band. The first seven characters are taken from the closest preceding band prefix line.

mmdd

is the month and day when the band was destroyed or its loss was noticed. This field is optional. If omitted, the output record will contain at least the correct year.

ssss

For multiple-station sets, encode the four-letter station code after the date, if it is known. Omit this part for single-station sets, as we can use the name of the batch file to infer the station where the band was lost or destroyed.
