Hello Marcus,

In your original reply you said that variable sharing was a python concept, So I wrote my block in python.

I would like to do something like the block "variable" or the "probe signal" block that shares a variable will all blocks in GNUradio

I want to do a block that changes the samp_rate or the center frequency automatically if a condition is true inside my block.

Hi Marcus,

An example I can think of is let's say there's a channel estimation block followed by an equalizer block. 

Let's say the channel estimator estimates the channel by looking for a training sequence in the incoming data. Once it finds the training sequence it needs to transfer the data into the equalizer which it will through its output port. 

But how is the channel vector sent to the equalizer? Its not going to be a constant stream, it may just be a fixed vector of so and so number of taps. Is there a way to make the equalizer see this channel vector?
