OK just got my resistors today, I undid the previous 2 solder mods and put on this one.  At 1000mhz i don't seem to be accepting any shares, also using 0 Watts measured with the Kilowatt.  Any ideas?

Double check the continuity with your DVM..
The inside solder point looks open...
Solder it to one or the other points next to each other. They are the same connection on the pcb as one was for a capacitor next to R52
Always double check.
It really sounds like your resistor is not in circuit.


I have resoldered this twice now and tested with DMM in OHM mode, I get a drop across the reistor for sure, but still not working.  I think my problem is I have messed up the pad on the outside where the resistor goes.  Anywhere else I can tie into?  Maybe from the bottom if I have to?
