I purchased a one year old K2 #5116. Its equipped with the KSB2 SSB module. I noticed the filter selection for CW Wide wasn’t set up with OP-1 as per the instructions for the KSB-2. So I went into the Cal Fil and set all the BFO settings exactly as per the KSB2 manual to allow OP-1 to be used in place of FL-1 on CW Wide. Then I used the Spectrogram software to set the filters exactly as per the instructions. All the filters tuned up perfectly . All went well exact for one thing. On CW Reverse, using OP-1, I can hear both sides of zero beat on the CW signals --- at the same level. So with an S9 signal I have to tune through both sides of zero beat at S9 but only using CW Reverse. e CW Normal using OP-1 has prefect side band suppression with no sign of the other side of zero beat. I can tune CW signals while in either USB or LSB mode and it receives perfectly with no sign of the other side of zero beat. So SSB suppression on both USB and LSB appears to be ok. The only thing that’s not coming up right is while using OP-1 in place of FL-1 on CW Reverse. Everything else appears to be working as it should be in this K2. Anyone have any ideas on what to look for as the cause?
