gDay Peter,
without being familiar with the exact circuitry, my immediate response is the same as Lou's. Check to see if the oscillators are oscillating. It is a good sign that you are hearing broadband noise... at least some RF energy is getting through! If you can detect output voltage from the oscillator using the RF probe and yet still cannot tune in local signals, this implies that the frequency is wrong.
