I believe the Kel-Tec serial numbers are a modified 34base. The KT system doesn't use "I" and "O" since they would be confussed with "1" and "0". Also the two least significant places are base 10.
Here is a chart to convert to numerical (10base).

"H" for P3AT and "J" around fall 2006
"P" for PLR16
"A" for P11
"R" for PF9
