Greetings,
I'm trying to build a computer controlled AM/FM receiver. I know a enough about electronics to get in the ball park of knowing what I need to do but now I'm a little flummoxed so I turn to you.
I need to control 12 radios simultaneously from a computer, to achieve this I'll use a 12 output channel audio interface. I'll step up the voltage and have this voltage controlling a varactor cicuit. I can write the code for the computer but It's finding the correct circuit I'm having trouble with.
The circuit needs ideally to have a linear tuning characteristics, if this is impossible then at least a curve I can bias for in the computer code
I don't need anything too fancy with regards to locking into stations, this is for an art project and not to build a superb radio receiver.
Is there anything I'll need to be careful with in regards to stepping up the voltage?
Many many thanks,
O
