I had an early k3 with all the trimmings, 2ndRX 144xvtr multiple filters and the panadapter. When contesting there is none better for the money. That being said, I sold it all when I moved because of the operating I was planning to do didn't include contesting and I needed something more compact. To go further, an Elecraft system relies heavily on interconnecting cables. I found some issues with this and the overall experience had been not so good as the cables would go intermittent and cause weird problems. Still, once you go panadapter, you never go back! I purchased the Icom 7300 because its compact size and computer interoperability were excellent and the panadapter was built in. I may reconsider Elecraft if they build a rig with the panadapter built in with the same performance as the k3.
