Channel estimation OFDM saving taps

Hello.

Thank you in advance for the help...

I already searched the mailing list and could not find it how to properly see/save the channel taps from the OFDM Channel Estimation block. I saw that is in a tag, but how can I save it? 

What I'd love to find is a way to see the channel estimation with the 52 taps in a QT GUI plot. Is that possible? If it's not, saving it it's already awesome.

Thank you!!
