Did you replace Q3?
Are you getting a signal from Q2?
The 56
hm: resistor won't reduce the range much if it's bypassed by 1nF but it will keep Q3 cool and stable under a wider temperature range.
audioguru's concern about your antenna bieng to short is valid because the voltage across the LC circuit will be well above the supply voltage due to resonant voltage magnification if the Q is too high. The emitter resistor should reduce this problem a little but never the less try increasing your antenna's length to about 750mm.
