I have been having problems with this scanner. I have the cable and software from this site recomended for thr pro 433. i got all the frequincies and trunking ids for the county i live in but when it is all uploaded in to the scanner it says everything is done and fine but when i go to scan the trunking chanels i hear nothing. the only time the 800 mhz works is when i search and when i do that i only have the frequincy. so i went with thouse frequincies and added the id's for the sheriff and police fire etc and nothing happens, is there a firmware update for the radio shack pro 433 or am i doing it wrong????? any and all help is welcome please help
