I received the Flex-5000a in July, 2007, and have been having a great time experimenting with various settings and software versions since then.  I primarily operate in cw mode, so have been focusing my efforts there.  However, it is a marvelous ssb rig and for the first time in a LONG time, I actually have a microphone connected and have been operating some ssb.

Below is a picture of W7WE in QSO on September 6, 2008.  I really enjoy seeing the cw signal on the Panascope display.
