Re: [Elecraft] No BFO
OK, I just crossed that bridge a few days ago. I didn't think I had a BFO. Look for an envelope marked E850099 and/or 41UH INDUCTOR, 5%. Or it may say L33 on it. Is that what you mean? It should be very fine wire wrapped many times around a toroid. Hope it helps.

[Elecraft] K1 or KX1? Looking mainly at receiver
I am looking for a backpack rig (3-5 day backpacking trips). I know the KX1 is more portable but I am wondering specifically about the receiver performance between the two. Also in regards to the K2. I know the K2 is a better reciever but I'm coming from one disappointment. I purchased another rig that I was going to use as my backpacking rig but it's reciever is not that great and nothing I do makes it better. I may want the world, but I would like to have a decent receiver. On top of that, as long as it transmits and is decent on batteries, the other functionality is marginal on my list of priorities.

Re: [Elecraft] K1 or KX1? Looking mainly at receiver
Jeremy, I own a K2 and a KX1, and have some opinions; but I think there is no hard and fast answer. The K2 is superb; its receiver is about as good as my Icom IC-7800; no joke. Yes there are a few conditions in which I prefer the Icom, but to me, that is an amazing feat given the price difference. My only suggestion that might improve the K2 receiver performance factor for me would be improving the noise blanker noise reduction DSP somewhat. When you say as long as it can transmit do you mean CW only? I assume so from your consideration of a KX1. I have not had my KX1 long enough or used it enough under varying circumstance, but it is more portable and has some nifty features, and is easier on the battery, and I do really like it. Perhaps you could share with us what rig you were disappointed by, and in what ways; since all solutions are compromises to some degree, it may help us better advise you. 73 de W5SV, Dave Jeremy Cowgar wrote: I am looking for a backpack rig (3-5 day backpacking trips).

The KX1 is hard to beat for your need. The Rx is about as good as you're going to find in that size radio, it is light, and with the paddle and ATU, is really trail-ready. I've been powering mine with an 850 maH Li-polymer battery I got at the local RC Model shop that weighs an ounce to two. 12V for about 4W, and it easily lasts thru a Spartan Sprint. Actually, it lasted through a dozen or so QSO's while on a 15-day cruise through the Panama Canal this spring. My only complaint when using the KX1 in the S.

RE: [Elecraft] K2 VCO
Dave, Your best chance is to look carefully at the thermistor board - such problems usually originate there - it is easy to create a solder bridge on that small board. You can often spot it by removing the front panel and control board and peek at the solder side of the board - if not, removal is the best way to check it, but then you have to solder on new wires to re-install it. 73, Don W3FPR -Original Message- I have started carrying out Alignment and Test, Part2 have hit a snag.

[Elecraft] K2 and Heil Pro set+ :results
Hello! I've been asking for comments about K2 compliance with Heil pro set plus (standard, not Ic-version). KSB2 worked when I built it and installed it. I use foot switch to key the radio. SSbC is set to 4:1 or 3:1 when working. 2:1 was reported to be too less. When using VOX I had to definitely use 4:1 or speak very loudy and use 3:1 SSbC. KSB2 is not modified. Now I have done it, built high performance radio with a lot of solder joints. And it's working. Thanks for help all who have consulted me off the list and via the list. Now there is no more to build. Maybe KAT2, KNB, DSP2 and KBT2 in future. I hope your US dollar is going to be so cheap as it is now. :) Rolf Moberg oh6kxl ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K1 or KX1? Looking mainly at receiver
Jeremy wrote: I know the KX1 is more portable but I am wondering specifically about the receiver performance between the two. If properly built, the K1 has a somewhat better receiver than the KX1 in most areas. The advantages of the K1 receiver over that of the KX1 are: (1) Bands of operation. The K1 offers 15m in addition to the bands on the KX1. This is important, even in waning solar cycles, because when it's open 15m is one of the finest of QRP bands. An additional two-band board will let you add 80m and 17m. The clocking limitations of the direct digital synthesis (DDS) chip in the KX1 prevent operation on bands much above 20m. (2) Receiver I.F. filtering. The K1 has a four-pole crystal filter. The KX1 has a three-pole filter. (3) More natural tuning. The K1 has an LC VFO which tunes as fast or as slow as you turn the dial. The KX1 has step-wise DDS tuning, with manually selectable tuning steps. Not as natural, IMHO. (4) Cleaner RF response since the K1 has an LC VFO for its local oscillator (LO). The KX1 uses a DDS (without PLL) for the LO. All DDS generation schemes (except DDS-locked PLL systems) have spurious outputs which adversely affect recever performance. (5) Good internal speaker on the K1. No speaker on the KX1. I don't like to be tied to the radio with a headset if I'm just casually listening to a QSO. (6) Front mounted controls. I hate top mounted controls, except as a concession to simplifying the design and reducing the cost of a rig. I do not consider them trail friendly. In the transmitter arena, the K1 offers higher power output if needed, lower spurious output (that DDS thing again), and most importantly the K1 ATU (KAT1) is a considerably wider range tuner compared to that of the KX1. However, in real life, whether you will notice some of these K1 advantages is open to question. The KX1 is indeed a fine little rig. Some of the KX1 advantges over the K1 are: (1) DDS gives crystal-like temperature stability, far better than the K1 (though the K1 is much better in this area than I would have expected for its LC VFO). (2) The KX1 can tune a wide segment of the HF spectrum and can thus serve as a small shortwave receiver for other things besides ham radio (SW broadcast stations and utility stations, etc.). The K1 covers only only the CW segments of its ham bands. (3) The KX1 receiver can function in either LSB or USB mode. You can tune the phone portion of 40m and 20m with it. The K1 receiver can only function in LSB mode. (4) A host of nice bells and whistles, like lighted frequency display, and audio annunciation (can be operated blind). The K1 has neither. (5) Very small bulk and light weight, even compared to the K1 (unless you start making extras like an external speaker for your KX1). I chose the K1 five years ago, three years before the KX1 became available. I would still chose it today, but I can understand the popularity of the KX1 especially if 15m isn't required. You can hardly go wrong either way. 73, Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K2, PSK31 microphone
The transformer is to break the ground loop of having the computer ground connected to the RF chassis ground of the radio and producing possible ground loop currents. In that case, you defeat the transformer if you connect the computer case to radio case. The computer case ground should be the 3rd pin on AC plug, and use that one alone for computer. That will correct any voltage difference due to a line filter in computer. Some audio lines are floating, and the transformer gives them a reference known load. The transformer is the way its done in commercial broadcasting to avoid hum problems.

RE: [Elecraft] K1 or KX1? Looking mainly at receiver
I got a K1 instead of a KX1 mainly because most of my field trips are day packing or car camping, not backpacking. The K1 is an exceptional performer, but I if my interests were in a backpacking rig, I would have gone with the KX1. I haven't been backpacking in a long time, but, from experience, at the end of the day, radio wasn't usually uppermost on my mind. Between all the chores necessary when making camp and spending some time with hiking friends or star gazing, you may find you will do a lot less radio than you had planned to do. The K1 with accessories is a lot of stuff to drag around if you don't use it much. The KX1 will be less of a burden. I think a realistic assessment of your needs will point to the right choice for you. The K1 and KX1 overlap in a lot of areas, but they really do serve different purposes.

[Elecraft] KAT2, why did it take me so long?
I just got back from my annual trek to Martha's Vineyard, but operating the K2 was a bit different this year. My home qth situation does not accommodate an ATU very well, so I avoided getting the KAT2. And, of course, once I added the KPA100, that issue seemed to become moot. However, when I'm at the Vineyard, I put the original lid back on to the K2 and operate qrp. I use my slingshot to throw a 112' wire into a tree (the other end is anchored to the lightning rod on the end of the converted barn) and I pitch a 33' counterpoise out the loft window. I used to tune this with an MFJ 934 tuner with artificial ground. This worked very well on 80-10. But then I began thinking: if I am going to use the original lid only under these kinds of circumstances, maybe it makes sense to add the KAT2. Which is what I did. And, boy, yes!!! I sure don't know why I didn't do it earlier. Because I built the ATU just shortly before leaving and didn't have much time to test it except to see that it was working, I lugged along the MFJ box, just in case, and the MFJ-259, which is very useful in finding initial settings without using the K2's power. Well, that was a waste of space. I could have left those boxes at home, as well as an assortment of cables and a coax switch. The KAT2 tuned that same antenna set up (I added a second 16' cp) fantastically well on all bands 160-10 (1.1-1 or better). I just wish the bands were in as good shape as the KAT2 behaved. Although it tuned top band, I wondered just how well I would be able to get out. I tried twice and made good contacts both times, once getting a 599 from K9DX in IL (of course, he was about 30 db over s9, running a kw and an appropriate top-band antenna). Add to that the fact that the settings are remembered, so switching bands merely required pushing the band button, and, wow, who could ask for more. I sure don't know why I didn't do it earlier. best wishes, dave belsley, w1euy ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Well, it's good even if your not a reader, but you know what I mean. http://break.org/gisle/HamRadio/binaries/TASRT.pdf Jeremy KB8LFA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Linear operation with K2?

Can someone point me to some information about this so it will be linear ready when I get it done? Unless the linear requires you to switch a negative or AC voltage on transmit, the KPA100 is probably all set to drive a linear. Here are the specs for the amplifier keying interface: PA KEY output Compatibility DC relay coil, pulled to ground (do not use with AC-controlled relay) Current 1 A Voltage 200 VDC The switching is all solid-state and quite fast, so the K2 can directly drive a QSK linear with no special keying circuitry. For slower relays, you can set the delay to semi-QSK. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The K2/100 will switch most amps with no problem, but if you have a SB-200, SB-220, FL-2100, AL-1200, AL-1500 and probably several others that I have missed you need an interface between the two to have the amp follow the K2/100. 73 HankK8DD ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K1 or KX1? Looking mainly at receiver
It was reported: ... the KX1 wins handsdown for backpacking... Strange! Before the KX1 came out, the K1 was generally acknowledged as the best multi-band backpacking rig available. It is no less suitable for that task today. If one is happy with the limited number of bands covered by the KX1, and recognizes that there is absolutely **no** physical way that KX1 receiver RF performance can match that of a properly constructed K1 in any area other than VFO stability, and that the ATU in the KX1 can't come close to the matching range of the K1's KAT1, then the KX1 is a great choice. On the other hand, if RF performance *on the ham CW bands* is important, the K1 stands as the best of the two. When I'm out in the boonies, I want the best possible RF performance on the ham CW bands that I can get in a small package. The K1 hasn't been shaken from that position. I don't care that I can't use it for shortwave broadcasts or to copy the ham phone bands. I've got a Sony portable that'll do that quite adequately, with essential AM/FM coverage to boot. So whether the KX1 wins handsdown depends on the criteria applied. It doesn't win for me, handsdown or otherwise. 73, Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
