Englewood Fire has had some kind of interference on its TG for the past 30 mins or so. It doesn't sound like an open mike, it's kind of staticy. Isn't there some time-out on the DTRS where a radio will be cut off if its transmission exceeds, say 2 mins continuous? Or, can't dispatch lock out that radio until the issue is fixed? Dispatch was having a real hard time trying to copy units talking on the radio.
