I just finished the alignment using Spectrgram and all seems to be OK. The
rig will transmit on CW OK. I am getting no output on upper or lower
sideband. I'm using another receiver to listen to the K2's signal. I can
hear a tone when transmitting but no voice audio. Neither can I hear myself
in the headphones (Heil Pro-Set K2) with the 5.6K resistor between pins 1
and 6 and all 8 jumper's installed.
I run some voltage checks using the KSB2 manual and most were close to the
manuals reading except the following:
U1 Pin 16 should be 5.4 on TX and it is 3.08
U1 Pin 17 should be 5.6 on TX and it is 4.15
U1 Pin 28 should be 2.4 on TX and it is 5.44
U2 Pin 1 should be 5.6 on TX and it is 4.15
U3 Pin 5 should be 0.4 on both RX and TX and it is .26 on both
D11 on SSB should be 0 and it is .14
Any suggestions. I've probably been at this too long and am missing
something simple.
THANKS
Gary
