I am currently using PowerSDR v 2.4.4 built by SV1EIA with my Softrock Ensemble RXTX. It has gotten me started in SDR, I'm really liking it, and I'm ready to move up. I just purchased a Flex-3000 and will be downloading a current version of PowerSDR for that radio. Can two versions of PSDR co-exist without problems? Can I download a newer version without changing/updating the previous version? Thanks for the advise.
