I've recently got my hands on some ancient mobile phone base station
amplifiers which I've managed to retune to 435Mhz +- 5MHz but I need some
help with choosing the voltage to run them at.
Does anyone in this group have any knowledge of such old cellular hardware?
Specifically power and logic voltages used?
I am sorry I can't help you directly, but "435Mhz +- 5MHz" has never
been a
cell band*, in fact it is well within the American 70. CM band.
(420-450 MHz.)
It might have been designed as a pager transmitter and some HAM has
adjusted for amateur use. The manufacturer and model number would be
very helpful in helping you further.
