@phooky what _is_ that thing on the left
@er1n it's an MDT-9100T, a mobile terminal meant for installation in cars; I've removed the radio component.
@phooky @er1n I've seen modern versions of this used by London Ambulance Service (until they moved to Airwave/Tetra digital comms in the late 2000s) although prior to that the blue light services where I then lived (Reading, about 60km West of London) all still used analogue voice comms.
Interesting to learn the Dutch Police used it (and with better encryption than the USA agencies had!)

@bunnyhero @phooky @er1n would have made sense for such things as info about a patient, an incident report etc (no GUI so screens of forms would be filled in on the MDT and when it was complete "send" (possibly the # on the telephone style keypad) pressed to key the radio and transmit the data (usually as FSK). ISTR hearing this kind of data mixed in with voice when scanning on VHF low band in late 90s UK (think it was vehicle recovery services such AA/RAC).
@phooky @er1n those crytpo cards are probably all probably all still locked away somewhere at AIVD Zoetemeer (NL security service)... I got the impression crypto wasn't widely used outside NL and it would have cost a lot too (Philips most likely got govt subsidies to build the system as they still had a lot more presence in NL back then)
