Re: [Elecraft] [KX3] 160-80 meter mod?
I did the mod and yes currently there are SMD parts at the locations of the four devices you need to replace. I had no trouble heating the existing devices to remove them. I also had no problem soldering the new devices in place. It was normal two pad SMD stuff, nothing special. For reference I am reasonably experienced at soldering, but only moderately so at doing SMD work.

Re: [Elecraft] [KX3] 160-80 meter mod?
John, The 160/80 meter mod that improves IMD dynamic range requires replacing a total of four parts in the T/R switching and one of the BP filters. The mod would not be overly difficult for someone proficient with SMD rework but I wouldn't recommend it for someone who isn't. To answer your question, trying to break off the existing parts would most likely damage the board. The areas are also pretty dense, so soldering iron access is a bit tricky in a couple spots. 73, Rich AC7MA On 01/09/2013 06:12 AM, John Fritze wrote: Can anyone who has done the 160/80 meter LP filter mod tell me if there are parts now on the pads on the circuit board?
