Re: [Discuss-gnuradio] Constant carrier digital transmission

[Marcus Müller]

Hi Frank,

**which** post from March 2009? Would you happen to have a mailing list
archive [1] link (please don't use Nabble).

At any rate, what applied 7 years ago regarding messages will probably
not apply now, anymore.

I think it would be very worthwhile if we didn't discuss this based on
something from 2009; what program/flowgraph/python script are you
specifically looking at?

Best regards,
Marcus
