In short: I can't hear the usual rx-noise between dots/dashes. Only in a wordspace, when cw-ing slow it sounds like QSK. T-R settings works however, ie there is a difference in tx-rx timing, played with the 8r line setting but there seems to be no real solution Noticed this today, I thought it was different when I build it but I'm not sure. Any comments? 73 Eric PA3CEV K2/100 #960
