K1 band module.

I have just bought a K1-2 from eBay. It works well and I am quite
pleased with it. It is configured for 40 and 20. My question is, can I buy the 4 band board, and configure it for 80, 40, 30, 20? It looks like the 4 band must start at 40, unless I am reading something wrong. 73 Steve W2SES _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

No, the 4 band board cannot do 80.
You can order the parts from Elecraft to modify your 2 band board to work on 80.

Steve,
The K1 4 band board has only 2 low pass filters, so the band combinations are limited. 40 and 30 meters can share the same low pass, and 20, 17 and 15 can also share a low pass filter - so with the 4 band board, it is 40 and 30 meters plus your choice of 2 bands from the 20, 17, 15 meter combination. The K1 can remember settings for 6 bands, so you can use the 2 band board to fill in any gaps that your 4 band board does not cover. If you have the same band on both boards, it will work, but the operating frequency calibration setting will only be remembered for one of them, so it is best to have the 2 band board setup for bands not covered with the 4 band board. Band kits for the 2 band board are available from Elecraft, so you can change the bands covered, you are not slaved to the bands currently installed on that board. 73, Don W3FPR W2SES wrote: > I have just bought a K1-2 from eBay.

Thanks to everyone who replied. I now understand the limitations and
can proceed. 73 Steve W2SES Don Wilhelm wrote: > Steve, > > The K1 4 band board has only 2 low pass filters, so the band > combinations are limited. 40 and 30 meters can share the same low > pass, and 20, 17 and 15 can also share a low pass filter - so with the > 4 band board, it is 40 and 30 meters plus your choice of 2 bands from > the 20, 17, 15 meter combination. > > The K1 can remember settings for 6 bands, so you can use the 2 band > board to fill in any gaps that your 4 band board does not cover.

It'll do even better...it stores data for nine bands. The K1 MPU stores a display calibration adjustment for each ham band that the K1 MPU allows to be assigned to a filter board. Although there are only six HF bands provided by Elecraft for the K1 (80/40/30/20/17/15 meters), if one designed filter boards for the nine bands that the K1 MPU can assign to a filter board (160/80/40/30/20/17/15/12/10 meters), a band-specific display cal adjustment will be stored for *each* of those nine bands.

RIGHT! I have....so far....have three band cards now. 40/30/20/15 four
band, 80/40 two band, 160/80 two band. IF it EVER opens again, 10 meters would be nice! Lately, I have been using my K1 with the T1 external tuner as it's range is a bit greater than the internal tuner. I wondered if say an 80-10 meter version would be possible with two "piggy back" boards sacrificing the internal tuner space? 73, Sandy W5TVW ----- Original Message ----- From: "Mike Morrow" <[hidden email]> To: <[hidden email]> Sent: Wednesday, June 25, 2008 9:17 PM Subject: Re: [Elecraft] K1 band module. >> The K1 can remember settings for 6 bands... > > It'll do even better...it stores data for nine bands.
