Flexradio Flex-6300 transceiver cw ptt problem in SSDR Version 1.10.16

I have discovered that the 6300 does indeed hold the output PTT on as requested by the PC. Unfortunately there is a firmware bug which ignores the input PTT to the 6300 and allows it to unmute the rx as if in semi break-in mode complying to the set delay. This leads to hearing rx hiss between transmitted cw words as the linear is in tx mode and therefore the 6300 rx isn't connected to the antenna. This leads to very tired ears during a 24hr contest with audio hiss chopping in and out during transmit. Flexradio support aren't listening even although they have been told about this problem for years now. I myself have had 2 support tickets ignored. Their beta team cw guys must exclusively use full-break-in and probably don't contest much and are happy with the way it is. I know one flex owner who has thrown the towel in over this issue already. I'm enjoying contesting with the 6300 and although the rx noise during tx is annoying, I can put up with it for now...
