Kenwood TS520S problem

[eddie8005]

Hello all,
I just acquires a Kenwood TS520S radio and hooked it up. It seems to receive fine on CW mode, but there is no audio on LSB or USB mode. I am not familiar with this radio and cannot seem to figure what is wrong (whether its the radio or me!) Does anyone have and insight into this? Any help would be appreciated!

Thanks,
Ed

Ed;

First, get a copy of the service manual, then check to see if all three carrier oscillator crystals are working. There is one for CW, one for USB and one for LSB.

Thanks. I will do that.. It's strange - no background noise or anything on LSB and USB...
