Maybe the oscillator isn't working. If so, the receiver will be dead. Use
another short wave receiver to listen for it. Put the antenna lead of that
receiver close to the oscillator coils and tune it to the SX-25 frequency
+/- 455 kHz. It should resemble a strong carrier. Verify you are listening
to the oscillator by tuning the SX-25 to another frequency. The signal
should disappear.
Practice on the third band first, so you don't have a cockpit error
problem. I'm talking about the mixer-oscillator oscillator, not the BFO.
