Re: [Elecraft] P3 Panadapter with K2
Does anyone know if the P3 Panadapter will work with the K2 transceiver? It does, with a number of caveats: - The K2 does not have an IF Out port. On my K2, I never installed the no-antennatuner BNC connector; I modified the connector to use a small coax cable (AWAY from the high RF output of the antenna circuit to avoid leaks) and re-purposed the BNC for "IF Out". In hindsight, perhaps I should have used a SMA connector and some filler rings (for the same hole at the back of the K2) - You need an IF buffer amplifier. Search for "Clifton Laboratories Z1". The buffer amplifier comes in two versions, Z1-K2 and Z1-U. You want the K2 model, or get the universal model and add the 4.915 Mhz filtering. - The IF output is a tad low, you won't see "the bottom of the band" though I still found this useful - The P3 cannot talk to the K2. Which means that there won't be frequencies on the P3 display, nor can you make the P3 "shift" as you can make the K3 do. The center will be the frequency you are receiving (which I consider most useful anyway), but that's what you get. - The K2 has some BFO leakage back into the IF. For reception that does not matter; however for spectrum display you will find a spike in the center of the frequency you are receiving. There are some mods to make it "less" but not "gone". If you have a live band you probably won't notice; I was using the QO100 passband on which signals have a max strength of 24dB above noise and then the spike shows. I did not find it objectionable. I do suggest you take some time to look up the original Clifton Z1 documentation; it is a piece of art on the same standard as the K2 manual if not higher. I learned quite some things by just looking at the documentation. It is very unfortunate that Jack is no longer with us; however production of the amplifier has been taken over by DX engineering who sells pre-built boards which seem to be of similar standard as the ones Jack provided. Is it useful? Definitely! Recommended? Yes. But you should know the limitations, which is why my posting is more verbose. 73, Geert Jan PE1HZG __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] P3 Panadapter with K2
Bill, If you add the Clifton Labs Z2 buffer amplifier (now sold by DX Engineering) to provide an IF output from the K2, it will work as a spectrum display. It will not report the K2 VFO frequency as it does with the K3. 73, Don W3FPR On 1/24/2023 3:03 PM, William Santos via Elecraft wrote: Does anyone know if the P3 Panadapter will work with the K2 transceiver? __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

The K2 doesn’t have an IF out, unless it has been modified.

Even with a modified K2, the P3 cannot achieve the same level of integration that it has with the K3.

Re: [Elecraft] P3 panadapter with K2?
You'll need to add a buffer amp, at the very least, like this: http://www.cliftonlaboratories.com/z1_buffer_amp.htm Normally this would be used with a softrock rather than a P3, so I haven't really looked into what else might be required to integrate and make the K2 work with the P3. 73, Matt VK2RQ > On 4 Aug 2014, at 7:06 am, Thomas Taylor wrote: > > Has anyone on this list used a P3 panadapter with the K2 transceiver?
