RE: [Elecraft] Moving the bands on k1 modules
Chris, The K1 4 band board shares the low pass filter with 2 bands, so 80 and 40 meters as the lower band pair will not work because the 2nd harmonic energy from 80 would not be attenuated by a LPF that will also pass 40 meter signals. 40 and 30 meters work with the same LPF and 20 and 17 (or 15) meters will work with the same LPF, and that is what is done on the 4 band board. 73, Don W3FPR -Original Message- Hi, I have ordered one K1-4 plus KFL1-2, should soon arrive here in SM. I have choosen 40/30/20/17 mtrs in k1-4 and 80/15 on KFL1-2 board and will probably build this way, but i just wondering about doing this way: 80/40/30/20 K1-4 and 17/15 on KFL1-2, is that possible with the existing parts included in kit? By this way i will not need to swap boards when changing between 40 and 80 mtrs.. 73 / SM5KRI Chris ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Moving the bands on k1 modules
The way the K1 RF boards are designed, the 4 band one won't work on 80/40/30/20! I have my 4 band board on 40/30/20/15 and an additional 2 band board for 160/80. 73, Sandy W5TVW - Original Message - From: Krister Eriksson [EMAIL PROTECTED] To: Elecraft@mailman.qth.net Sent: Wednesday, June 14, 2006 10:57 PM Subject: [Elecraft] Moving the bands on k1 modules | Hi, | I have ordered one K1-4 plus KFL1-2, should soon arrive here in SM. | | I have choosen 40/30/20/17 mtrs in k1-4 and 80/15 on KFL1-2 board and | will probably build this way, but i just wondering about doing this way: | 80/40/30/20 K1-4 and 17/15 on KFL1-2, is that possible with the existing | parts included in kit? | | By this way i will not need to swap boards when changing between 40 and | 80 mtrs.. | | 73 / SM5KRI Chris | -- | Krister Eriksson | Ringduvegatan 23 | 724 70 Västerås | | [Hamradio: SM5KRI] | [ [EMAIL PROTECTED] ] | | | -- | SM5KRI | Krister Eriksson | [EMAIL PROTECTED] | | ___ | Elecraft mailing list | Post to: Elecraft@mailman.qth.net | You must be a subscriber to post to the list. | Subscriber Info (Addr.

Re: [Elecraft] Moving the bands on k1 modules
Because of the way the K1 4-band board is designed (2 bands share a set of bandpass and lowpass filters (40/30 and 20/17) as opposed to the 2-band board which can accept any two bands, since each has it's own set of filters) you can not do as you describe. You can't get much more out of it than what is described on the elecraft site. If you want 80/40/30/20 in one case you could get a KX1 + KXB3080, but those are the only bands you can get in it. dt . --- Krister Eriksson [EMAIL PROTECTED] wrote: Hi, I have ordered one K1-4 plus KFL1-2, should soon arrive here in SM.

Re: [Elecraft] Moving the bands on k1 modules
You can't get much more out of it than what is described on the elecraft site. Except that, rather than supporting 40/30/20m plus either 17 OR 15 meters, the KFL1-4 filter board is actually a little more versatile. As supplied, it supports 40/30m, plus ANY TWO of 20m, 17m, or 15m. I don't know why Elecraft doesn't take credit for this. Every once in a while a person comes around who doesn't care about 20m coverage. Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
