Re: [Elecraft] Difference between a K3 and a K3S

I bought a K3S and then I upgraded my #4XXX K3 which has two receivers with every upgrade that Elecraft offered. It was mostly just a fun project, but it's also a backup for the shack. One thing though, I swapped all the filters and just put the 2.7KHz ones I got with the K3S in the K3. And I also

The new I/O board was also an option that was sold separately as an upgrade to the K3, as was the KXV3B, where the pre-amp was located. If you find a K3 with all those upgrades plus the synth (like mine ;), it's pretty close to the same thing as the K3S. On Mon, Jan 25, 2021 at 7:48 AM AB1DD

The difference between a "dry" and an "air cooled"? I think they are the same. The difference is with "oil cooled". Heathkit used to sell a "Cantenna" which was a dummy load in a gallon paint can. Add your own transformer oil. IIRC it was rated for a KW for a short period. Ken WA8JXM On

A dry dummy load is good for up to its power rating - but do not exceed that rating. The air cooled dummy loads not only require power for the fan, but may be over-rated for their power spec. I prefer dry or oil immersed dummy loads. A good dummy load should present a 1.0 SWR for all the

Re: [Elecraft] Difference in DSP in K2 and K3S

Paul, Comparing the technical side of the K2 DSP NR with the K3 NR is like comparing apples and oranges. The KDSP2 is DSP added at audio, while the K3 NR is done at the 15kHz IF. The K3 offers many more settings that are available with the K2 DSP, so I encourage you to experiment some more.
