Joplin agencies are digital. I currently use my digital scanner and I'd rather not commit to using it as a feed scanner. However, If an event should happen again like the Joplin tornado or the threat of a severe weather breakout I will connect and monitor Joplin fire and ems.
Also. Anytime you mix analog and digital audio you are bound to have a constant volume problem. Digital audio punches through loudly where as analog be seem distant at times. This would cause some frustration with listeners that would be able to hear some agencies and not others.
