Hmmm..odd that it didnt complain about a 9k but did about a 2k. being 2048 byte but trimmed to 0-2047 in you hex editor.
Well you know it does something. The radio may have hung on the fact that the byte id is set for UHF.
I dont know why you 2k LB is failing. Try putting the full 9k LB file in the emulator.
If that fails I'll make one and post it. What do you want in it. 10m 6m and w/ some slaved PLs?
