Yes, I've tried that, it doesn't make any sense.  I was hoping it was at
least a sequential database and we could start filling in the blanks...

Here's some of mine sorted by label:

3/80    BA22    08:00:20:08:0b:a4
SS1+    E7RG    08:00:20:09:80:dc
SS1+    F78G    08:00:20:09:f4:ee
ELC    H5KT    08:00:20:04:08:bd
ELC    I1LT    08:00:20:04:aa:e1
SS2    LEAF    08:00:20:10:96:bc
IPX    RWQ3    08:00:20:0d:65:68
SS2    UPYK    08:00:20:1b:f2:81
SS10    Y6R5    08:00:20:1d:a9:01

notice though that the H5KT, I1LT, and LEAF seem to be out of order with the
rest.
