Hi Marcus,
The situation still is same.
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

Hi Marcus,
The issue is even I put the vector source toggling with 1 and 0s it transmit a signal. So I need something that will not transmit at all and switch between these 2 radio chains.
Thanks,

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.

Hi Muller / Marcus,
I got the testing right now, but unfortunately it doesn’t work while I put it in my original file.
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 ?

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.
