"I have three Pro 2006's and there are no gaps in them. They are continuous through the 800mhz band." Do you mean none of your 2006's have been modified? Perhaps this issue was addressed in later units. I bought my 2006 new in the spring of 1992. It would not receive 868.9500 to 868.9875 prior to modification. The last public safety frequency before the cell phone band is 868.9875.
