[Discuss-gnuradio] RFX900 Failure

[David Evans]

Hi all,

Power output has significantly dropped, initially by 8dB, now much more.

My first thoughts are that the PA has failed, so is it possible to break 
the transmitter...
- by prolonged transmitting at high power (i.e. setting it to/near maximum)?
- using a mismatched antenna?
- mismatching resulting in VSWR effects? (err, without a load)?

I'm obviously going to have to test now, where to start, any 
suggestions, like what voltage swing before and after the 3315 should I 
expect?

Many Thanks
David
