[Heathkit] HW101 CW Question

[Bwana Bob]

Scott:

The HW-101 uses the same BFO crystal and oscillator for CW reception and 
USB reception. If you are not receiving CW correctly, but USB reception 
is OK, check the contacts on the Mode switch and look for a cold solder 
joint on the switch. In receive, make sure that you have B+ on V16A, pin 
1 in both the CW and USB positions.

( For CW transmit, a different oscillator and crystal are used. The CW 
transmit crystal is also selected by the function switch and the 
transmit or receive oscillator is selected by a set of relay contacts. 
In CW or LSB transmit, the B+ is switched to V16B, pin 6. If you have CW 
transmit problems, check the Function switch and  relay contacts. As a 
last resort, you may have a cold solder joint on the Y3 CW carrier 
crystal pins or a bad crystal.)

                             73,

                             Bob WB2VUF

In receive, I can hear static and not a clear tone on CW with the switch in the CW mode. If I move it to either LSB or USB then I can hear the tone just fine.
