CW RF power Drop Outs
It is disappointing to have to raise this subject yet again after nearly 5 years during which we CW operators have continued to experience the dropping out of RF power whist transmitting.
For anyone new to this old topic the issue is summarised as follows :-
Whilst sending CW using any form of manual key the RF power output stops despite the CW sidetone still continuing thus giving the impression of still transmitting. The power RF output can only be restored by allowing the radio to go back into RX after which the RF power will continue when the keying is continued, that is until the next time which may be within seconds, minutes or even hours. It is happening on version 2 and 3 software and to both 6500 and 6600 series radios and most likely all models. The curious thing is that it never happens when keying is being carried out directly by a macro such as from N1MM, only by manual keying be it straight key or paddle.
This fault has been reported time and time again over the past few years by many CW operators but as yet there is no fix or even proper acknowledgement by Flex about the fault or what action is being taken.
It makes for a difficult CW sending technique with the only solution being to shorten the CW hold time delay to try to overcome it which is not a good solution when using a linear amp and should not be necessary anyway.
All CW operators local to me here in the UK are experiencing this problem and it is nothing to do with our station installations. It happens when using an antenna or dummy load and is nothing to do with RFI in the shack etc.
My own situation, and I know that of friends experiencing this problem, is to seriously consider the continued use of Flex radios. In fact I already have an Elecraft K4 which it looks as though I will have to use in lieu of my Flex in order to restore correct operation at my station. However, I like the Flex radio but unless this fault is fixed I may have to bin it as being unfit for purpose.
A formal response is thus required by Flex radio.
My system is Flex 6500, latest v3 software, Maestro plus PC with W10.
