[Elecraft] K2 Low/No pwr out on SSB except 80 and 40m

[Don Wilhelm]

Stewart,

There is no band dependency in the KSB2, so your problem is most likely 
associated with your filter setting for SSB FL1, particularly the USB 
BFO setting.

While the settings given in the KSB2 manual are usually a good starting 
point, they are not optimum for any one particular set of crystals.  I 
strongly suggest that you use Spectrogram to align the filters.  If you 
are not familiar with Spectrogram, take a look at Part 3 of the K2 Dial 
Calibration article on my website www.w3fpr.com.

If you have trouble after aligning the filters with Spectrogram, we can 
provide additional help, and if you have not yet constructed the RF 
Probe from the parts provided with your K2 kit, it will likely come in 
handy for that troubleshooting.

73,
