No, complete editing is possible with out scanner connected, indeed the two things are completely seperate. Of course the information does not get to the radio without uploading the new file.Alanman,
Today I played around some with USDA and my original comment completely missed the mark. USDA has a different user interface depending on if the scanner is connected. It does not seem possible that complete off-line editing is possible when the scanner is not connected.
On the other hand every-time you connect the scanner it immediately downloads the current data and rather quickly compared to arc396. I like arc396 because I have complete edit control when the radio is not connected, but the downside is I have to keep track of what I lasted loaded and did I make any changes on the radio that I should capture in a new profile or mem data file....
