I've done everything like you all described, but I get this output:

Could you tell me what's wrong? I think that the signal is too weak...
I know this is an old post but I had the same problem. I'm just letting people know my findings..
I had the blacklist issue too.
I was getting audio but it was scratchy, I knew it wasn't a signal problem because when I plugged the antenna into one of my uniden scanners it was loud and clear. Which pointed to dongle or tuning... I played around trying to adjust the frequency and that didn't seem to make much differency. Then I found this http://davidnelson.me/?p=371
on RTL SDR frequency correction and the magical -p option in rtl_fm ... the audio cleared up and the moment I started piping to multimon I had pager text spewing out beautifully!!
my command line
sudo rlt_fm -M fm -f 148.6375M -s 22050 -o 4 -p 30 | multimon-ng -t raw -a POCSAG1200 -v1 -f alpha /dev/stdin
Now to figure out how to feed filter and feed what I want to my mobile devices!!
