With these simple xcvrs, first I always want get the xtal oscillator running. You said "no oscillation", assume this means you hear no signal near the xtal frequency in the icom. The oscillator runs all of the time, no oscillator means no receive and no transmit. Are the crystal leads making contact? Is there voltage to the oscillator collector? The oscillator uses a pretty rugged bipolar transistor so doubt is toast.
