Well, in my case the tx/rx would not be stationary, so the channel is not
quite.

If you can tolerate the stream stopping, use Power Squelch. Otherwise,
time to dive in and follow Tom's advice from May - disable the CMA taps
update loop when there's no signal. This whole idea assumes you have a
mostly quiet channel, stationary tx/rx, etc. Interested to hear what you
come up
I applied this and this is useful in condition when you do not want to
process noise, because it is being multiplied by zero when there is no
signal. But I want that CMA taps remain unchanged when there is no signal
or just noise. In the above scenario CMA taps change due to presence of
noise, beca
Try using a "threshold" off the "mag squared" and feed that into a
multiplier after block2 (with appropriate type adapters). As long as
block2 doesn't have a huge delay or do rate changes, this should work.

Hi thanks for your comment. block2 is the gnuradio "CMA equalizer block". I
want the CMA block to remain quiet when there is no signal of interest.

Saw this the other day, but there isn't a lot to go on here. If block2
is your own, you can make it do the bypass. You can also use some of the
logic blocks and a multiplier depending on what you're doing. There
isn't really a concept of on-the-fly switching in GNU Radio.

People, any ideas on it?

I have following flowgraph:

What I want to do is that I want to bypass the "work" function of block2
when the threshold level of probe_mag_squared reaches. I do not want to
stop(), lock(), disconnect the flow graph. Is this possible u
