Alan,
The KX1 comes natively with only 40 and 20 meter bands. The KXB380 option adds 80 and 30 meters. The KXAT1 antenna tuner has a limited range, and is optimized for the no-feedline antenna shown on page 10 of the KXAT1 manual for 40 through 20 operation. Use of the KX1 on 80 meters requires an antenna that is close to resonance. 73, Don W3FPR On 5/6/2015 11:44 PM, Alan KB7MBI via Elecraft wrote: > A good friend of mine is interested in purchasing a KX1 primarily for use > on 80m.

This might be a bit like looking for hens teeth but you never know...
I am aware Elecraft don't do the 4 band version (about a year now) as the filter module trimmer caps are not available now. However, been asked by another who regrets selling his own 4 band version a while back if I know if there are any K1 4 band radio kits unmade available anywhere. (I gave mine away when the KX3 arrived!) I have asked a few that I would usually find might have had one but no joy, built ones yes but need an unmade kit, just the 4 band one. So, does anyone (prefer UK not US) have an unmade K1 4 band kit they might have squirrelled away they had not started for sale? They do not want one already built as want to build it themselves. They sold it to buy a KX3 they just don't use and prefer the simple display of the K1. Off list replies please. 72/73 Dom M1KTA ______________________________________________________________ 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 Message delivered to [hidden email] |

Hello Mike,
Yes, this has already been covered in my review written in eham. I have a lot of reservation in the construction of KX1 with the additional KXB3080. If I were given the choice, I would simply give up the 80m. 73 Johnny VR2XMC 寄件人︰ Mike Morrow <[hidden email]> 收件人︰ [hidden email]; [hidden email] 傳送日期︰ 2015年05月7日 (週四) 7:38 PM 主題︰ Re: [Elecraft] KX1??? >A good friend of mine is interested in purchasing a KX1 primarily for use >on 80m.

I built the KX1 with the 80M option and I agree that it takes some extra care building it, but it works. I followed some of Don Wilhelm's advice when building it when I had some issue...I forget what.
It's a neat little rig.

In my opinion, the KX1 is a neat little package. But understand from the
outset that it was designed for sleeping bags, picnic tables, and short-term fun. If your intended use falls elsewhere, buy elsewhere. I would not recommend it for inexperienced builders or those with failing eyes and/or shaky hands. The 80/30 modification kit requires care and concentration. When completed, however, it's a satisfying piece of work, brilliantly designed. The builder's greatest dilemma involves the antenna connector . . . deciding what kind of antenna to attach. The success of any QRP installation lies with the antenna. Spend twice as much time and effort in researching that issue as you do in building the rig itself. 73, Kent K9ZTV On 5/6/2015 10:44 PM, Alan KB7MBI via Elecraft wrote: > A good friend of mine is interested in purchasing a KX1 primarily for use > on 80m.

My two bits on the KX1 and 80/30 option…
I built the KX1 40/20 version and I didn’t think it was too difficult. My only modern era kit building preparation for the KX1 was building a Norcal 40A. Although I wound my own toroids for the Norcal 40A, I chose the option of buying the ready made toroids for the KX1 (from the vendor whose contact info is on the Elecraft site). Winding the toroids was the only part of the kit-building that I didn’t like doing when I did it with the 40A. I purchased the 80/30 kit primarily to get the 30 meter band but I had Don, W3FPR, do the 80/30 kit add on and he did his usual excellent work. I have used the 80-meter portion only to check into an 80-meter CW net under QRP power a few times but using my home QTH and regular 80-meter dipole. Although every now and then I use the KX1 just for kicks, I usually rely on my KX3 for portable QRP operations. Actually, I even fired up the Norcal 40A last week for just a single contact just to make sure that it still worked after cleaning the dust off of it. My KX1 though does work on 80 meters and I did not have much trouble matching the antenna but it was with using a very descent antenna whose normal area of lower SWR was around 3560 KHz where I made my net contacts. I have never used the KX1 in portable operations with a compromise wire antenna and I probably never will. 73, phil, K7PEH > On May 7, 2015, at 8:11 AM, KENT TRIMBLE <[hidden email]> wrote: > > In my opinion, the KX1 is a neat little package.

The construction of the basic KX1 40/20 is not difficult and with less skills than K2. However, the LPF in the KXB3080 is quite a PTA. The manual does not give the sufficient forth warning to the builder. My review in eham net gave the details and areas to be paid attention:
http://www.eham.net/reviews/detail/3586 You would expect a lower power output after the installation of the KXB3080 (before and after comparison with my LP100A and RF probe) I would be happy to provide further details in the construction if some one is really going for it. 73 Johnny VR2XMC 寄件人︰ Phil Hystad <[hidden email]> 收件人︰ Elecraft Reflector Reflector <[hidden email]> 傳送日期︰ 2015年05月7日 (週四) 11:54 PM 主題︰ Re: [Elecraft] KX1???

I built the KX1, 30 meter board [not the 3080], and KXAT2 primarily to
take along on a cruise through the Panama Canal in 2005, Ft. Lauderdale to Los Angeles. Our cabin, only place they'd let me operate, was on the top deck, unfortunately on the port side of the ship [left side as you face the pointy part of the boat for the non-nauticals], and I basically heard nothing from NA. Lots of SA of course. I used a 1 Ah Li-poly, and it still had about 1/4 charge when we got home. KX1 build came after I built my K2 which included the KAT2 and SSB for which I've never gotten a mic. I would put the KX1 combo and K2 combo in the same category of "build-hardness," the K2 is a much larger project of course and took longer, but in terms of difficulty, the only thing I noticed about the KX1 was that more components were installed on the reverse side of the boards and I had to be careful I got that right. I can speak to 4-5 W on 80 CW with my K2 using a compromise field antenna ... I've only done it a handful of times ... QRP on 80 is hard. I'm happy with my 40/30/20 KX1. Dave, W8FGU, made me a very lightweight acrylic back to replace the metal one for Spartan Sprint. I don't think you can get the 30-only option anymore. KX1 is a shirt-pocket radio for those whose interest is back-packing with radio as a side activity along the way. It has a very cool LED lamp to light up your log at night. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 5/7/2015 4:00 PM, Johnny Siu wrote: > The construction of the basic KX1 40/20 is not difficult and with > less skills than K2.

The addition of 30m band does not require the construction of a new LPF and does not create any output power issue.
The construction of KXAT1 was also easy unless you have to install the new LPF for KXB3080. The construction of new LPF requires tight tolerance in the soldering of a number of componments on the RF board and KXAT1 board. These are not carefully and preciously mentioned in the manual. Without the KXB3080, KX1 can deliver 4-5W. However, with the installation of KXB3080, you will possibly lose 1 W in most of the bands and 3W in 80m. All measurement done by LP100A with a Bird dummy load. 73 Johnny VR2XMC 寄件人︰ Fred Jensen <[hidden email]> 收件人︰ [hidden email] 傳送日期︰ 2015年05月8日 (週五) 7:38 AM 主題︰ Re: [Elecraft] KX1???
