Re: QMX thump with CW keying


 

Thanks for posting that Stan. Very helpful. Has anyone implemented this work around on a revision 1 board, where C430 lies underneath one of the SMPS boards and there’s nowhere obvious to site the additional cap?

Is the only solution then to source a 33uF surface mount cap of appropriate size and fit that under the board? That would be a very fiddly task indeed given it lies in a string over other, very closely spaced, components.
