Re: Damaged resistor R520

Thanks Bojan and Steve I have those values. Much appreciated 73
Hi Rey
?
Looking at the circuit diagram R520 is a 49.9 ohm resistor, replacing this with a 5.1k would certainly affect the SWR readings.
?
You might get away with using a 47 or 51 ohm through hole resistor. If you have a batch of 47 and 51 ohm through hole resistors measure each one and see if you have one at the edge of its tolerance range.
?
Using the intended 49.9 ohm smd component would be ideal...even if you have to repair the PCB trace/pad with wire.
?
Good luck
