Turns out @latest will pull the latest tagged commit. I will need to make a new release to correct this. In the meantime, I would recommend cloning the repositories for rtlamr and rtlamr-collect directly with git.
from rtlamr-collect.

Did a little more digging and it looks like logMsg.Type doesn't have a value.
index fef931d..8694029 100644

+++ b/main.go
@@ -390,12 +390,17 @@ func main() {
msg = new(IDM)
case "R900", "R900BCD":
msg = new(R900)

}
// Parse the encapsulated message.
err = json.Unmarshal(logMsg.Message, msg)
if err != nil {
log.Println(errors.Wrap(err, "json unmarshal"))

}
The output is then:

Ah yeah, you're using incompatible versions of rtlamr and rtlamr-collect. The lastest flavor of rtlamr-collect expects there to be a "Type" field in each message and the latest version of rtlamr provides that field, but I've not yet made a tagged release including those changes. The release of go modules has been somewhat turbulent for this project.
Try:
go get -v github.com/bemasher/rtlamr@latest
go get -v github.com/bemasher/rtlamr-collect@latestfrom rtlamr-collect.

I just collected the latest versions using
go get -v github.com/bemasher/rtlamr@latest
go get -v github.com/bemasher/rtlamr-collect@latest
And received an infinite stream of Unmarshal(nil):

However, getting them normally seemed to work fine:
