Good Day all,
What happens to old cell phones? They seem to be throw away devices,
even tho they still work after the contract runs out. These days 2
years of use makes the phone ancient and worthless, regardless of
whether it still works or not.
But these things are full of good rf parts sensitive 800 mhz receivers
that can be put on 900 mhz ham bands and 3 watt transmitters that can
run cw or fm---since the receiver and the transmitter have to run in
close proximity to each other (and in full duplex), their LO's and
transmitter spectral output has to be squeaky clean. Of course, there
is a duplexer and the thing is loaded with top quality UHF rf
components. Some of them have 'test modes' which allows the user to
tune and transmit and manually control the frequencies from the
Anyway, I never see service manuals or other technical information for
these things and a one year old cellphone goes for 20 bucks or less on
ebay these days! 2 year old cell phones go for 3 for 20 bucks or so..
Has anyone hacked into these and published any information on using
them for alternative purposes???? Or gaining control of these things
in service mode? Does anyone deal in Service Manuals for these
Email me or post reply here.
Have a great day.
