Just completed build of the QMX mid bands. While installing T507, I accidently damaged R520 resistor (5.1K). I replaced it with a 4.7K thro hole resistor.
The radio powers up alright with all else working wine including Audio and RF sweeps normal. The SWR sweep however shows 2.6:1 on all bands. I have no doubt this is linked to the 4.7K resistor. Any suggestions on the best way forward. I do not have a 5.1K thro hole resistor. One of the pads has been damaged so an smd replacement is not an option.
Any suggestion is welcome please.
