This brings back very good memories. I used to work for a mobile phone company in the West Midlands in the UK and they had approximately 8 of these machines. 4 were used for function testing of the phones, 2 were used by the equipment repair section and 2 were in store as backups because these units do break down after a while. These units were only ever used for testing 'car phones'. A 'car phone' consisted of small box that housed the main electronics of the phone, a handset and lots of cabling to allow authorised car dealers to install the units. The function test area where these units were mainly used would have the test bench and a vibration rig next to it. The operator would clamp the main unit in the vibration rig and connect the handset to a box on the test bench that went from the bench to the vibration rig. The vibration rig was to simulate the conditions of the unit being in a vehicle that was travelling on the road. The rig could be sped up or slowed down depending on how fast or slow you wanted to simulate the speed of a vehicle. No one in the UK could repair these so when they broke down we always had to send them back directly to JRC in Japan. I notice on your unit someone has changed the rubber keys on the keypad because they never looked like that originally.
DBm is decibels per 1 meter. He’s measuring the RF output of the test transmitter to the mobile phone handset lol. You probably could use that as a miniature cellular network lol, if been wanting to mess with an old cell site transmitter for interlinking with amateur radio. Be the first amateur radio subscriber based cellular phone network lol.just be careful because Vodafone could have ofcon on speed dial.
@@Ilikecats731 not gonna happen sadly the big cellular companies have no interest since gsm and its derivates give them the most money. the only way its gonna happen its if enough people bring the tacs to the "big ones" as of now we re stuck with shitty cellular networks that always drops when calling, tacs never did that
Hello - any chance you have a manual I could get a copy of? I purchased one of these with no handset and want a schematic of it to build one. Please advise...

I hope I can get my hands on one of these!
That's built like old central office equipment from the 1980's.

is there a legal way to set up a analog cellular network?
NO
@@ppc7457 why? isn't it like legally setting up a 2g tower?
I kind of hope one day they will bring this cellular systems back or at least find a way to make new cellular towers to connect to amps phone
