Considering the following statement from http://www.flex-radio.com/Products.aspx?topic=f5k_features : "Designed from the ground up to be a true full duplex radio that can transmit and receive simultaneously without a second receiver installed. With this capability, the FLEX-5000 is now the ultimate CW rig ever made. " [Note the statement _NOW_ the ultimate] And the post here on May 21 of last year, in which Bob McGwier said: "With the Flex-5000... ..., the cw transmitter sounds like a sidetone inserted into the receiver which recovers instantly. In fact, we got it to switch so fast that we were hearing the TX carrier leakage... ... in the receiver after key up. The Flex 5000 switches very fast indeed. Full duplex in the software is the key to all of this new speed." I am beginning to wonder if CW in the production software is broken and only we in the field notice it. Or perhaps the production version does not presently include features of the version used by Bob above? When I returned my new 5000a for refund awhile back, it was solely because of poor CW QSK performance. I hope to buy another 5000 in the future, but only if/when CW performance of the production software is improved. For the phone ops out there who may not understand, QSK is the ability to actually hear activity on the band between dits at a reasonable speed. Modern radios like the 756PRO3 and K3 can do it at 30-50 WPM. Both use DSP.
