So I can put the SP3 in the closet for the rest of my life (next to other elecraft radios and accessories) or put it out for sale since Elecraft no longer makes them. What is the difference between a SP3 and a SP4? Looking at the pictures they seem similar apart from the text on the bezel. __ 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] KRC2 Band Decoder question
I have one which I've successfully used with my K3. I did find that in a QRO environment, you should be careful with RF coming in on the outputs. I had to hang some ferrites on them to prevent erratic operation. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ On 08/03/2023 9:28, Jim Brown wrote: On 3/7/2023 7:38 PM, AB2E Darrell wrote: Are there any issues using this with a K3? Not that I know of, Darrell, although there are a bunch of options covered in the manual. Should be on the website. W6GJB and I have been using a pair of KRC2s that N6RNO built to switch filter sets in his two-op contesting trailer. I'm usrf the single-coax feed from the AUX connector to the KRC2. Simplifies things a lot. The KRC2 is a rather early product, and shielding is non-existent, thanks to paint everywhere between stuff that should be bonding (like the connectors, and joints between parts of the chassis. A metal chassis provides no shielding if cable shields are not bonded to the chassis at the point of entry, and if shielding is not continuous. I took them apart and used a LOT of sandpaper. :) 73, Jim K9YC __ 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 k2vco@gmail.com __ 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

Does the stock DB9 cable to the rig need to be rewired for the K3? I want to hook it up for FD with a bandpass filter set. There are a number of ways to set up a KRC2, depending on how you want to interface it. With an Elecraft radio, you probably want to use the AUX bus. On the K2, for which the KRC2 was originally designed, the AUX signal is on the DE9 serial connector (and it's one of the reasons you cannot use a "straight cable" connecting a K2 to a serial device!!!). On the K3, the AUX signal is on the DE-15 ACC connector, NOT on the 9-pin serial port. The KRC2 documentation got updated for this, be sure you have the errate document describing connection to the K3: https://ftp.elecraft.com/KRC2/Manuals%20Downloads/KRC2_Manual_Errata_Rev_C4.pdf So make sure you get the errata document. 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
