Ok, had some time last night to work on this again and gave the pushbutton assembly (and the other controls) a good cleaning with a good electronic contact cleaner. Now it picks up lots of short wave stations with good volume. The broadcast band, however, now picks up a couple of stations but I have to have the volume at max to hear them. This brings up another question I have: what IF frequency does the short wave use? The schematic says 455 kc for "standard" and 4.5 mc for FM but doesn't indicate anything for short wave.
