Kenwood TK-361 need help to programme!!??

I have 5 Kenwood TK-361’s and they are all set to short range business radio frequencies, from what i can tell this has become an illegal frequencies as they were replaced with PMR 446. Can anyone tell me if theirs a way to re-programme they to lisence free PMR 446 so i can use them and how can i do this??

Please help

The TK-361 cannot be used in the PMR 446 service legally. That service requires a fixed, non-removable antenna, along with .5 watt power.

so their pretty much useless then?
