Re: [Elecraft] Will the K2 and KX3 work with the P3?
Robin, I have the NB installed in my K2 and I elected to use that option to install the IF buffer. The other option may offer slight improvement in performance, but I didn't feel it was worthwhile in my case. I haven't been using it long enough to give you any real feedback. Like you, I plan to use it primarily for CW and only occasionally for SSB. I hope to get on the CW test this weekend and see how it performs. From what I've seen so far, it does make it quite easy to spot openings as well as strong signals up and down the band. 73, Mike - W0AG On Fri, Aug 30, 2013 at 1:30 PM, Robin Bayer rmbaye...@gmail.com wrote: Hello Sir I was wondering where best to connect to the IF.

Re: [Elecraft] Will the K2 and KX3 work with the P3?
Robin, If you do decide to go the SoftRock/Clifton Labs route, be advised that both are kits containing SMD parts. Not a major obstacle, but you'll definitely need a good soldering iron with small tip and probably magnifying lenses to help locate and solder the little buggars! In addition, the 4.915 crystal for the SoftRock is also an SMD and you'll need to fabricate a mounting platform for it. Again, not a major problem - I used a small piece of circuit board and made 4 small pads with a Dremel. For software you might want to try Rocky first and then PowerSDR-IF. I currently am having the best luck with Rocky since it's pretty straight forward to get operational. PowerSDR might be better, but I've not quite mastered its setup as yet. 73, Mike - W0AG On Thu, Aug 29, 2013 at 5:02 PM, Robin Bayer rmbaye...@gmail.com wrote: Hello Sir I am looking for a description of what is required and what I can expect Fromm the Clifton labs IF buffer/amp/filter installation, assembly, and operations.

Michael, There are some who would want to do just that. I recently had a customer who wanted to use his LP-Pam or P3 with his K2; I added the Clifton Labs Z1-k2 for him. He already had the LP-Pan and the P3 available.

The KX3 I/Q output is set up to feed into a typical computer sound card (stereo, line-in) and a Softrock SDR-type program, which is easier than trying to jerry-rig a P3. You can potentially use a CAT interface with the KX3 to query the current frequency, for SDR software display. I have NOT one this directly, so I don't know what SDR software support that. 73, Terry, WB4JFI __ 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 __ 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
[Elecraft] Will the K2 and KX3 work with the P3?
Hi I know that the P3 requires a serial connection to the K3 and the appropriate firmware and that this does not exist for the K2 and Kx3. However, will it display the spectrum? And if it does, can one emulate the serial commands via the P3 serial port? I am wondering if this could be an option in my software Win4K3 Suite if I provide a K2 and KX3 version.

Re: [Elecraft] Will the K2 and KX3 work with the P3?
I have determined that I can emulate the firmware and provide full functionality via serial commands. Now, would there be an interest for P3 usage on a kx3 or k2?

Re: [Elecraft] Will the K2 and KX3 work with the P3?
I'm not sure what you are trying to accomplish here with the KX3, pardon if I mis-interpret. Using a P3 requires that two issues be resolved: 1) control and, 2) RF signal input. P3 control is via the serial RS232 connection, and can be figured out. However, the P3 wants to a single RF signal at its IF input. It then goes through a typical DDC-based SDR approach, including an FFT, to display the spectrum. The P3 works with the 8.215MHz IF output of the K3 (or many other RF-frequency range, IF signals). The KX3 does NOT have a single RF/IF output at the proper frequency. Instead, it has an I/Q output pair at audio frequencies (0Hz-approx 48kHz or so) from the internal QSD. You would need to upconvert that I/Q pair back to a single RF signal in order to feed it to the P3. That's a lot of work, with much simpler solutions available. I don't know much about the K2. Looking at the manual, internally, it has an 4.9152MHz IF, but I don't think that's available on a connector, or if the drive level is buffered and adequate. If so, you could use a P3 with a K2 I suppose. The IF would need to be tapped BEFORE the crystal filtering. I do NOT see an IF output connector, and only one transistor buffer between the mixer and the crystal filters. The KX3 I/Q output is set up to feed into a typical computer sound card (stereo, line-in) and a Softrock SDR-type program, which is easier than trying to jerry-rig a P3. You can potentially use a CAT interface with the KX3 to query the current frequency, for SDR software display. I have NOT one this directly, so I don't know what SDR software support that. 73, Terry, WB4JFI -Original Message- From: Tom Sent: Tuesday, August 27, 2013 11:35 PM To: Elecraft Subject: Re: [Elecraft] Will the K2 and KX3 work with the P3?
