Yes I see 'U's on the console. However I am not sure that the implementation
contain such element (tx_eob).
I've checked the mac.cc code but did not found something referring to a tag
or end of burst.

May be that's why I may see that narrow band signal. If may understanding is
correct that should be fixed right and I should add such tag in the packet
structure.

But If for example I try to use 0.5 as value (blocks.multiply_vcc(0.5)) I
got this error:
TypeError: in method 'multiply_cc_make', argument 1 of type 'size_t'
