[SOLVED] [MOVED]How to fix the receiver unit of this radio?

[mvs sarma]

If possibe try to lift the L15 from the junction of D1 andD8 and connectto antenna externally. At this stage perhaps other signals might interfere, but wanted signals can be checked for sensitivity. If there is improvement, then we can think that the antenna filter section is giving trouble.

Problem solved: I replaced D8, and Q6 then sensitivity came back to normal comparing to another radio.
BS. I also replaced D13, D7, and D1 because I'm not sure whether I burned them with soldering iron after I removed them off the board for testing.
Thanks all you guys.

I lost R11 (560 ohm)when I removed D1. I should be stick to the soldering iron and I can't find it now.

Can I use a carbon film resistor instead of SMD resistor on the board?

Good work. Pat yourself on the back.

For replacing R11, an ordinary resistor should be just as good as surface mount.
