I try to do some 'helloworld' type tests and I found a problem. I write code
in Python using UHD as the interface to HF HW. I can successfully receive
stream samples and push it to the filters / demodulator / bells /

problem to make it working simultaneously on Rx and Tx. It looks like
instantiation problem - rx stuff grabs E100 and does not mat it to be shared
by tx. Is there any example of such (or similar) code - just working one.

I have also another issue - I will have to decode something from rx then
send 'predefined' samples and then do repeat after 'remodulation'
(regeneration). Is tehre any hint how to do it from the Python code?

What software do you have on your e100? Kernel and uhd?
