I want to realise a simple OOK transmitter in gnuradio companion to turn on and off my wireless wallplugs. Basically my flowgarph is working, but I am a little bit confused why
I set up the graph according to examples that I found on the wiki (https://myriadrf.org/news/limesdr-made-simple-part-7-one-way-continued/)
Using this graph, the final transmission is not on 433.595 Mhz but on 433.19 Mhz. Disabling the blocks Signal Source, Multiplication, Throttle and connecting the Repeat block directly to the TX sink, results in the correct transmission frequency. Why is this happening? Does the Sink block itself multiply the input signal so that, in my graph, the multiplication is being done twice ?
Second question: Does I really need the throttle block in this graph? The throttling is done via the TX sink, isn’t it ?
Thank you very much for your time
Kind regards, Rush
