Re: vector source python block

[Barry Duggan]

Hi,

Without seeing your flowgraph, it is hard to tell what you plan to do 
with the vectors. In gereral, the "speed" ultimately is determined by 
input and/or output devices such as USB or a sound card. If you have 
neither one, a throttle block will limit the throughput.

As an example of a custom vector source, see 
https://github.com/duggabe/gr-morse-code-gen which generates vectors of 
dots and dashes for Morse Code. If you start at the audio output (48khz) 
and work backwards, you will see how the sample rates determine the 
desired speed in words per minute.

If you haven't already done so, it would be helpful for you to work 
through the

Let us know if you have more specific questions.

Best wishes,
