Dave, actually CLK2 signal SHOULD be on pin 10 of IC3 all the time. But it should only be on pin 8, as well as coming into the antenna port end of the low pass filter and into the receiver when in the alignment mode. This mode is turned on when a high from the microprocessor comes in to pin 9 of IC3.
You should probably check continuity through the bandpass filter as a starting point. If all that looks good then check out Hans’ troubleshooting procedure on the website. It tells some steps to take to troubleshoot the receiver front end.
