thank for taking an interest in my problem with this 800. I have seen it ghost talk groups and re arrange them too. but now that I replaced the 8 gb card from the replaced 4 gb card, I ran into dos at about 150 entries. so I tried to reload on same number but it would not. so then I loaded the miss entry on the next number and transferred it in to the correct number. I have done this twice at around 200 entries. now at about 300 entries. now see that I am about half populated and probably have to many entries on some numbers. scan sets still a ways away. well any how the bad guys prevailed last night and the good guys the night before. always exciting at night in the 3 rd most populated county in the nation. really need advise on should I put in more towers or less with the 800. our smallest out fitted wrecker has 4 197 they seem to work better with just 2 simulcast frequencies. but that is also if you are with in 5 miles of a tower . it is a rare thing when I can make both scanners hit off the scan on the 700 frequency. every day is a brave new day in the digital world.
