433MHz transmitter/receiver

[markp]

Hi All,

Has anyone used these 433 MHz 433MHz transmitter/receivers before?

The quoted sensitivity of -155db seems too good to be true, as is the
transmission distance (but that is quoted at 18db, i.e. around 64mW. You can
only use 10mW in Europe).

Any thoughts?

Mark.

Are you talking about the RX434? The blurb quotes sensitivity at
155dBm, which is about 3 TeraWatts - that's one DEAF receiver!
Alternatively, click on the link to the pdf...sensitivity is
now -115dBm, which is a little more credible.
