Unfortunately you won't be able to measure an RF signal at the IF output connector with a meter or oscilloscope unless you have a REALLY strong signal at the K3 antenna input.
As a general sanity check, you could do a DC voltage measurement on the JFET just to make sure it is still drawing current. I don't know the exact voltage, but I imagine you should get a volt or two on the JFET source (R9 source resistor). That does require taking the bottom panel off the K3 again.
