Hi,

AFAIS, you call the output message port "gain", but try to publish to the message port "gain_port". When I changed it to use "gain", it seems to work.

Best,
Bastian

In the attached flow graph, I've created a block, "gain setter" that takes in a number of input items and after the input items reach a certain amount, the block will issue a command to the ursp sink to change the gain to a certain value. I basically did this using a loop. However, it doesn't seem like the gain of the signal changes according to the freq sink plot of the received signal. Any ideas??
