Hi all, CW on 2m is a problem. Especially with speeds higher than 25 wpm the timing of the sidetone becomes very unregular (eg. continues keying of dots only). With an external keyer the problem seems to be even worse. QRQ CW sounds very dirty. CW on HF bands is perfect. Any others who can confirm this problem? 73, paul hb9axl MCU 2.25 DSP 1.30
