Well, I received my replacement parts today, but so far in spite of my best efforts, I've been unable to desolder the K12 relay from my RF board. I've used a combination of solder wick and a pump, and I can see though the holes at this stage, but I still can't get the relay free! What's the preferred method of doing this?
