There is no audio filter yet (except de-emphasis) so you get pretty
much 48 kHz worth of noise, including stereo pilot tone and whatever
crap they include in a broadcast FM channel these days.
I put in some debugging code near the filter tap

Hi lists,
I've installed the lastest GNU Radio and UHD by build-gnuradio script on
Ubuntu 12.04 LTS, everything is OK. I run the uhd_fft.grc example with

I have tried using the branch (bd6d01b) but it doesn't help (same

When I have some spare time I will try on a different system that has

You are almost certainly sampling faster than your computer can
handle, the queue gets backed up and WXFFT stops responding to GUI
messages, sample at a slower rate. My old PC can not do more than 1
Msps w/o locking up.

In comparison to the rtlsdr fork I see you added FM-W. FM-N in
comparison sounds more clipped, FM-W is clipped
The Verilog code is all available and it is in the UHD git repository. I
would suggest you start there.

I apologize if I'm misunderstanding your question. But the packet decoder
in GNU Radio is not an AX.25, just a general purpose decode. I've hacked
together an AX.25 receiver with the N200. I can send the files to you
tomorrow.

Yeah I figured that was the main issue, an AX.25 encoder/decoder would be
awesome!

All,
I have been playing with stream tags since a while and eventually come across a
problem. I have a block A which generates a series of tags. The output of block
A is then passed through an interpolation block B. So, a tag which was
associated with sample X in block A becomes associated
Don't change the offset, catch the tag in a downstream block and issue a
new tag with the modified sample number.
We've been debating ways to handle decimating/interpolating blocks in the
tag scheme, I don't think we'd settled on any consistent way to handle
non-sync blocks.
