Well, this is a strange deal and I'm not seeing anything in the archives relative to this particular situation.

Just installed the KSB2  in K2 #  6272...................

Finished the alignment and filter settings....

Figured I would play with it for awhile and see how it does. WRONG :-)

Low power on all bands except 40 mtrs. ( on SSB ) No / or very weak ALC / RF response regardless of SSBA and SSBC settings.

It's fine on 40 mtrs with good drive and output.

This is still a QRP   K2  with KAT2,  KNB2 and now KSB2 installed.....

All tests and alignments were spot on and the rig works like a dream on CW on all bands. All functions are working as they should etc.

I switch mic's and no change. ( before I realized it was fine on 40 ) I have an external watt meter in line with the antenna and it shows 40 meters around 10 watts while all other bands are down around 1 or 2 watts
( including 80 )
Rig shows good ALC and RF on the bar graff on 40 but very weak on all other bands.

I wondered if the tuner was giving some problems so changed modes to CW and it has lots of power on all bands. ( check each band comparing CW to SSB and no power on SSB while CW if fine )

I'm guessing it's something I overlooked but it's been a long day. I'll dig into this tomorrow. Any ideas of what I missed would certainly be appreciated.

Thanks and 72: Jerry N0JRN
