inject a 1000uV (or higher) signal in to the antenna jack.

connect your scope to the antenna jack and set it so you can see the signal coming in.

now follow the receive path to see where you lose the signal.

I'll do the very first parts to get you started.

check both sides of C43 (im using a galaxy DX33 so i hope part numbers are the same)
then C45. then emitter of TR17. then collector of TR17. then L7 and L8 etc...

the signal should be getting larger as it gets amplified. when you hit a place where the signal lowers significantly or goes away completely, you have found your bad section/part.
