Depending upon where you have your scanner located, your indoor coverage is probably NOT the best. I am hearing the portable coverage in the Sleepy Eye/Springfield area is questionable indoors.
Also, in order to hear anything off the Evan site, a talkgroup you want to hear on a scanner must have a subscriber radio affiliated to that site with the talkgroup you want to hear selected. Your local PD & FD may be actually affiliating with the New Ulm site, therefore you would not always hear them.
