Hello,
I would like you to check some thing(s) and let me know what you see. First on the radio, press the band key until the first digit of the "channel number" on the right side shows "A" (example "A01 or A99". If you can't seem to see this, check to see if above the channel number it shows "MR". If it doesn't show "MR" then you need to press "V/M". After you are in the "A" bank turn the scroll knob in both directions and see if anything that you entered is there. If nothing seems to be there, it may still be somewhere in the radio. Press the band key until the channel number says "000" there are two consecutive banks that say 000, the first one shows a "R" just above and to the left of the number. The next band (which also says 000 but without the R) is the one you need to look at. This is the master memory band, which shows all the channels from 000 to 999. Scroll through these and see if your channels are there somewhere. If not, They may not have transferred from the software to the radio. If you saved your work in a file, you may not have to enter it again. I normally save my files by date name (example 09202005a) (the "a" is the first save of that day) If you can't find your work in the file you saved, you will have to enter them again, unfortunately. When you are programming the radio, you should be putting the frequencies into the 000-999 channels and then adding then to the "A" (or other bank of your choice).
