I am a total noob in this world of trunking and my knowledge is based on some internet guides etc., but I have a problem.
I work for a volunteer responder group in Finland (Red Cross first aid group), and we have a bunch of MTS2000s. I managed to read the devices and add conventional channels to them. Now I would like to play with the trunking system. The problem is that I need a system key to do that. The information I got from the radios is that they have firmware form 6.10 to 6.52, flashcode is 200008-000000-8, so they are capable of 250 modes and SmartZone systems. The system package is H38.
I tried to make system keys with the Batlabs method with Hex Workshop 4.2, but the CPS didn't recognize them (CPS 2.03.00).
How have you guys made your system keys to work? Idiotproof instructions would be appreciated

Thanks in advance,
FRC
