I have two out of tree blocks I want to add to GRC, everything compiles
installs correctly except for the GRC component (not shown in GRC). So
should be an XML issue and I think it is related to my attempts at
drop down option choice concerning the detection of white space/closed
frequencies and verbose output. My XML is attached below and you can see
that under Params Desired Detection and Verbose have options.
When I look at other stock GNU Radio block’s XML like the low pass
I see that some params have opt tags. Do I need these also, if so how
I use them in my case?
