With the new PRO-94 B's they can be opened,.. but no one has yet gotton to writing the programming software ...... As to keypad tricks,... none that do fancy programming bypass/overide functions yet.....
I have a feeling that someone will show off their computer super hacker genius and do a mod plug or code plug/software interface soon.
Here is the 94 family history:
PRO-94 TT-2, Can't scan conventional and TT at the same time.... and can't put conventional and trunked in same bank.
Pro-94 A TT-2, Can do both conventional and TT at same time and can do both in same bank.
PRO-94 B TT-2, Now has an PC/IF port BUT- NO SOFTWARE to program/PC Control YET!
PRO-2052 TT-2, can't do TT and conventional together, but does have mil air, and fully PC Programmable, and Controllable.
Both 1000 Chan., TT-2's that do Motorola I, II, and IIi, as well as EDACS Analog.
