Philips FM1000 Series (FM1100/FM1200/FM1300)
This radio is EXTREMELY flexible and has a loyal following in the amateur
The major drawback for mobile use is that the alphanumeric LCD display could be better - it's not very readable unless you're close in and directly in front of it. OK, so my eyesight's not what it was, but the STORNO 6000 has a gas discharge display that's far better, except in full sun. At night, the only form of illumination available on the FM1000 control head is a piddly little lightbulb with a green cover situated just behind the volume knob which is barely able to make the LCD visible. Not up to modern standards at all.
Philips FM1000 Series PMR Mobiles (FM1100, FM1200)
This is the handbook issued to all users of the FM1200(ESI) and covers the functions programmed in for the Electricity Supply Industry JRC-Band trunked network.
This manual gives instructions on how to use the network diagnostics (Engineering Mode) of certain suitably-equipped Electricity Supply Industry JRC-Band trunked network FM1200 Mobiles. Other versions of the FM1200-series may have similar functionality, YMMV...
This is the full System Functional Description for the FM1200(ESI version) which describes exactly how the radio shall interact with the ESI network. Probably of use to those with an interest in how trunked radio networks work - especially the slighty non-standard ESI one - "It's MPT1327, Jim, but not as we know it..".
