Well, I just tried to actually edit a codeplug and shoot a radio---what an experience. SLOW, really really SLOW. Reads slow, writes SLOW, loads SLOW, edited fields react SLOW. To actually build a code plug would be excruciating. I cannot sort zones. The radio will display zones alphabetically (numbers 1st, then letters) and it is nice to be able to display them the same way in CPS, but no you can't. You click on a channel in a list and after awhile it will open the single channel view for editing. When you make a change the software takes forever to react and display results. Then when you wish to go back list, you have to click on zone again in the tree and after you have gone to make coffee it finally shows up. All in all I find the software unusable. I have Kenwood FPU which loads extremely slowly but once loaded the field react in reasonable time and radio reads and writes are reasonably fast. I have only 1 updated radio fortunately so remainder units are on CPS 16. I have only loaded the CPS on 1 laptop and not shop desktops so maybe this problem is peculiar to my laptop, and if so I apologise for the rant. Any one else have a different experience?
