I did some googling and I am not seeing any modification, but I thought I would post here to see if anyone here knew a way of opening up the spectrum to more than just the marine band.
As a side note, the STANDARD HORIZON HX350S has served me very well. It was carried a lot and used very little. It's submersion rating is better than advertised.
