Igor, Just what does this delay?
Does it inhibit RF output from the K3 for 30 ms? If so it may chop parts of CW characters. The formula T=1200/W gives the dot length for a given WPM (W) At 40 wpm, one dot is 30 ms. Does it delay return to RX? 73 de Brian/K3KO n 10/29/2012 19:54, Igor Sokolov wrote: > I had similar problem. > The solution I use is the external TX delay circuit of 30 ms > (adjustable) that utilizes 1 FET transistor, capacitor and couple of > resistors.
