I recently moved my Flex 3000 to a new computer and downloaded and installed PowerSDR 18.104.22.16846. I'm using JT-65, which receives OK, but when I transmit I can hear the tones from the speakers in MON, but there's no output from the transmitter. I also hear the word "trial" spoken every few seconds from the speakers. What's going on? I've used this radio with another computer and a previous version of PowerSDR with no problems. Any help is appreciated.
