Hi Jay,
you're trying to talk to something that expects a specific protocol (it
seems to be JSON over some kind of TCP-based connection – wild guess,
there might also be a layer of HTTP in between), so you need to
implement that protocol. This isn't specific to GNU Radio, this is just
general
Hi
- What does "negative Tx power" means ?
A few suggestions:
move to GNURadio >=3.8 (most of us uses GR 3.8 or 3.9 so
it's difficult to help for outdated GR 3.7)

the flowgraph with an external modulator and different settings to see what
worked best.

delay to be 58 and set it as the default in the attached flowgraph.

Hi Mike,
Thanks for your help!
As I mentioned in my email, my flowgraph consists of some of the blocks in
the example. I dropped some of the blocks because I am doing concept
testing to ensure I know how to set parameters for the blocks. In terms of
delays, that is not a problem. I am dumping the
Hi George,

the block in the attached. (I disabled your file creation and displayed
to gui, easier for me to check.)
Little things are the hardest to spot. :-)

Thank you very much! I will give it a try a
