K1: Band options
Locked
 
|
Although I haven't received it yet, I have just picked up a very well spec'd
K1 on ebay. It has the both the KFL1-4 (40/30/20/17 and 15m crystal) and the KFL1-2 which is for 40/20. I know that the two boards can co-exist to produce a six band transceiver - or at least that's how I read it, but clearly in my case there would be no benefit since 40/20 are already there on the four band board. I am wondering what would be involved in modifying the two band board for 80/15 - that seems to be an option at build time. Any advice gratefully received! 73 Stephen G4SJP ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

To modify K1 2-band modules, first buy parts for the desired bands at
http://www.elecraft.com/order_form_parts.htm#K1 Parts Then change (only) the necessary parts on the 2-band module. For 80, I believe that you have to modify the main K1 board as well. You will need the K1 manual to set up the new bands when you finish soldering. 73, Paul W8TM ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

All,
Thanks for the clarification about the boards, I had completely misread what I saw on the Elecraft website, thinking that I could have both installed at the same time, stupid really! I'd rather have 17m than 15m, so I shall modify the 2 band board for 80m and 15m I think. I shall look into the main board modification for 80m, I'll download a manual from the website later. Most grateful to you all, thread closed. The K1 should be here tomorrow, I hope the K3/P3 don't get jealous! 73, Stephen G4SJP ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Stephen :
You can either have a KFL-4 OR a KFL-2 in the K1, not both at the same time. Swapping the boards involves opening the case, and removing the ATU (if present) before you can get at the band board. This process requires the removal and reinstallation of a few screws so it is probably not the sort of thing that you want to do on the fly, in the field.

I have a K1 with a 4 band board for 40/30/20/15. Also built a two band
board for 160 and 80 meters. This isn't a normally kitted option, but it is easy to do with the two band board. Elecraft has ALL the parts to do the 160 meter band EXCEPT the crystal, which in my case I bought from International Crystals. It covers 1.8-1.95 (about) and works great. I also have a dual band 80/40 board which stays in the K1 usually thru the winter. 73, Sandy W5TVW -----Original Message----- From: Stephen Prior Sent: Monday, September 19, 2011 10:15 AM To: Elecraft Subject: [Elecraft] K1: Band options Although I haven't received it yet, I have just picked up a very well spec'd K1 on ebay.

All,
I have just had my original reply rejected, so I hope this one gets through.
