I currently have a 6500 (using V2 SmartSDR) and I just received a seven day old used 6400 that I bought a week ago from another operator. Since the SmartSDR license is tied to the radio, can both rigs be run at the same time on the same computer utilizing their respective SmartSDR license? I searched around the community and didn't find an answer to my specific question. The reason for asking is I plan to use the 6400 exclusively with VHF/UHF transverters. Thanks in advance.
