[Elecraft] K2 IF Amp

[Peter]

Hi 
I´m just doing receiver signal tracing using the Elecraft RF probe. Coming to measure signal at U12 there are 300mV at pin 4 but only 1 or 2 mV at pin 8 no change if I increase the generator input or RF gain to max. The same with U11 at pin 1, when I increase RF Gain I get n o more than 30mV at pin 5 of U11. Across the crystal filter I get only about 100 mV at W3 with 1,4 V at W2. Is that a matter of the filter circuit or the IF amp MC1350. Thanks for any help...
