NFM TX with branch "next"?

GNU Radio
1

Hi,

A few days ago I tested the latest “next” branch, now it builds on a 32
bit
Kubuntu 12.04 without any problems - but it seems to me that still the
good
old analog stuff is not completely supported, or am I wrong? Just needed
a
dual tone in NFM, so I put together two signal source blocks, an add
block,
NFM TX and the USRP, and I still get an error message like (not
literally,
just from my memory) “no channel model available”. Am I doing smth.
wrong?
The very same GRC file loaded into “master” branch just does what it
should.

Is anybody from the list visiting SIGINT 2013 in Cologne / Kln?

Ralph.

There was a recent bug on the next branch related to gr-uhd, could you
please retry with the very latest?

OK, I will give it another try, but I wonder if it may have to do with
grextras not being compatible with the new API? There are two NFM TX
blocks
available in my installation, both do not work under next, but with
different errors.

After the next try I will give exact copies of the messages…

Ah, I was unaware that you were using grextras. That does not work with
the next branch, and in fact is not a part of GNU Radio but a set of
extensions developed and supported by Ettus R…
