433MHz receiver

[hantz]

Dear Colleagues,

I'm a beginner in the field of the microconntollers, and I would like to solve the following problem:

I would like to receive the 433MHz signals of several types of emitters, and further analyze them with computer. At the beginning, I would just like to see at least the main characteristics of the signals, like with an oscilloscope, if possible.

The RF.GET, I think, it's not suitable for this: it supports only the Holtek-12bit encoding.
How could I generally receive any kind of signals and transmit them to a computer via rs232?

In the future, I would like to apply garage key transmitters using the Holtek-18bit encoding. Is it possible to modity the RF.GET function to fit this?

And, does anybody have a _simple_ program using the RF.GET, to receive any kind of signnal emitted by a garage opener? The demo programs for RF and IR in the EAM booklet have syntax errors.

Thanks,
Peter
