By K2DLS
Here are the necessary patches for out of band (ie ham) use of this software version:

rui41.dll 0x2729 changed to 83 E0 00

ProRadio.exe changed as follows:

0027e45d EB 58
0027e4c3 EB 58
002f3864 EB 58
0027e4bb EB 58

You can then change the upper and/or lower bandsplit for the radio (at your own risk).
