During the past year that I have had my 6500, I have noticed that in certain instances the received CW signal tends to be noise modulated. Much more so than with my old TenTec Omni6+. Today I ran both from the same antenna using a 50 ohm splitter and tried to nail this thing down. My take is that both radios do copy weak signals just as good, but the Flex tends to have more noise on signals that are 10-20 dB above noise floor. Shouldn't the SNR go pretty linear from noise floor and up? The received signal sounds cleaner on the TenTec. I have to dig deeper into this, and try see if I can verify this using proper instruments. Right now I do not have a SINAD-meter. I am curious if anyone else have noticed this apparent less SNR? AGC-T nor equalizer seems to help, WNB; NB and NR are off. Test today used SSDR on PC and audio straight from radio.
