No, I have had both the PCR2500 and WinRadio tuned to the same 40-meter armature band and both sounded the same.
I'm sure in some frequency range, this does take place, but I have yet experience it yet. I thought about that allot before I purchased the G305i. One thing that is imperative, you must use the best sound card you can afford for the WinRadio. It makes a big difference. However, I like the G305. If the P25 software is good, I just might sell my PCR2500. I will report my findings when it is released.
