Are your VCO cans also on freq?

remember that what you hear out of the speaker is the 34mhz VCO signal, mixed with the 7.8mhz signal.
so, if one of the two settings is off, the output freq will be off also.

also, are you sure that your freq counter didn't load down the IF circuit?

that signal is at a pretty low level, and can be tricky to sample.
