I have an AEA PK232 that has been upgraded by Timewave to a PK-232 MBX ver 7.2, with the PacTOR Gateway and GPS options. Unit is used, but in excellent condition. Has the original AEA PK-232 manual, plus the Timewave PK-232 MBX manual. If you're interested, contact me off the list. I will send you inside and= outside pictures of the unit if you would like.
