I have just put together the KSB2 SSB ADAPTER and I have problems.
Referring to the manual on page 15 “Initial Test” the last paragraph
“Verify that the K2 performs...” I do not get any sound in the
loudspeaker, or the sound I get is very very muted. I can hear some very
faint - both CW and SSB – signals but only when the volume is turned up
to max.
Else there is no problem doing the “BFO Test”, “Receive-Mode SSB Filter
Test” and “BFO Setup for LSB/USB”
I have checked the voltages as seen on page 23 in the manual and found
the following anomalies in receive mode:
U1-21... zero volt (should be 5.8)
U2-5.... 6.0 volt (should be 0.6)
U4-3.... 6.0 volt (should be 0.6)
D10-D13 and D6-D9... no voltage in receive mode.
So, what could be the matter?
