Hey Marcus, I think the Selector block works well with my setup.
But I need a solution with which I can do a dynamic change in the input/output index. Can you let me know how is this possible Ayaz From: Ayaz Mahmud<mailto:ayazmah...@hotmail.com> Sent: Tuesday, July 17, 2018 4:39 PM To: Marcus D.

By browsing the archive I found some switching of blocks with SELECTOR. Is there any example that will be helpful on how this block actually functions ? Thanks Ayaz From: Marcus D.

So I need something that will not transmit at all and switch between these 2 radio chains. Thanks, Ayaz You're probably seeing the residual LO leakage during periods of "no transmit". You can try using offset-tuning to move the leakage out-of-band: Use: uhd.tune_request(frequency,offset) In the UHD sink for the "frequency" field. From: Marcus D.

Here is the attached .grc where I have used vector source as input and multiply a period with 1 and then with zeros on one radio channel and opposite on the other. Can you please have a look, and check if I am doing anything wrong ? Ayaz You're asking us to debug a very complex signal flow. Why don't you try something a *lot* simpler to get the TX-flow-switching-logic correct first, and then work up from there.
