I was just scanning Halton's p25 system and I see an id come on the scanner I have never seen prior. This was id 705 and it kept repeating an automated phrase "711 Appleby line, refer to printout for incident type" or very similar. I was wondering if anyone knew what this is or why it was broadcasting. It repeated this phrase for about 10 mins before I finally had to lock it out. Any insight would be appreciated.
