OS PCR800 (rain) gives 'Rain-Rate' = not supported

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Connect rfxtrx433 to raspberry
2.  Start rfxcmd
3.  Wait until data passes

What is the expected output? What do you see instead?
Extpected value for rainrate, instead of 'not supported', because in your 
sensorprintouts the PCR800 give a correct value

What version of the product are you using? On what operating system?
0.3 alpha, download at 24-07-2013 on raspberry

Please provide any additional information below.

Hi, it seems to me that the source in 0.30 to much chanched from 0.24.
Look at Rain sensors 0x55 and the source beneath that.

Greetings,

I changed my code in v030 of 0x55 to the code found in your svn.
This seems to be working correct now.

Wright no it's bad weather : raining and so on. RESULT :

Accoring to this i think your sourcecode voor 0x55 is not correct ......
