[Elecraft] KX1 vs. K1
Ariel wrote: I am not sure why nobody mentioned the KX1. It has 4 watts output, 4 bands, weighs next to nothing, 55 mA on receive, and with a 4500mA SLA (1 lb) or the equivalent LiFePo which is half the weight... The KX1 is a really outstanding QRP radio. But... 1. It can not cover any ham band higher than 20m due to limitations of the DDS circuitry. As solar activity cycle 24 progresses, these are precisely the bands that will provide the best and most interesting QRP operation. The stock K1 is ready with factory support for 15m and 17m. Then, 10m and 12m is easily feasible as described here by ones who have developed the necessary KFL1-2 filter changes for that. I'm not sure why Elecraft has never produced a 10m/12m filter parts kit during the K1's 12-year existence (all the way back to the end of solar cycle 22). 2. Its KXAT1 ATU only creates 124 different combinations of L and C and L-C configuration within a very limited range of L and C. By contrast: ATU L/C Combos L Range in NL Steps C Range in NC Steps KXAT1 124 0 to 4.5 uH in 8 steps 0 to 140 pF in 8 steps KAT1 1020 0 to 4.9 uH in 16 steps 0 to 300 pF in 32 steps T1 32764 0 to 7.5 uH in 128 steps 0 to 1300 pF in 128 steps KAT3 131068 0 to 17.4 uH in 256 steps 0 to 2600 pF in 256 steps KXAT3 ---Said to be the same as the KAT3--- Thus, even the K1's ATU KAT1 has considerably versatility. 3. The KX1 has only a three-pole crystal filter. It is possible to hear both sidebands of a strong signal. The K1 has a four-pole crystal filter, and that makes a noticeable improvement. There are other issues in a KX1 to K1 comparison, but they don't need discussing now. From this limited list only items 1 and 3 are important to me, because I don't use antennas that require a lot of reactance insertion by a tuner. If the higher bands are not desired I think that the KX1 is an amazing rig. It's certainly the smallest and most energy efficient one that Elecraft markets. Its most serious issue, IMHO, occurs at time of build from the trickiness of backfitting the 80m/30m band parts. Who wouldn't want their KX1 to be fully capable of all four bands? If I couldn't have a K1, I could be happy with a KX1.

The mail archive provided by AC6RM is a great resource with a great search facility. Try it by going to http://www.ac6rm.net/mailarchive/html/elecraft-list/ And do a search on 'K1 and Kx1 compared' The first hit by Bruce Prior N7RR is comprehensive and Wayne has added an extra aspect in the second hit on the list. 73, Nigel ZL2DF ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] KX1 vs K1
Oh, please tell me more. For home use, which rig has a better receiver? Which one sounds better? Does one have the advantage over the other if you're NOT leaving home? - Keith N1AS - - K2 5411 - -Original Message- The K1 is a much more pleasant rig to use and has a performance advantage.

Some say that the K1 sounds better than the K2. The KX1 has a much wider tuning range. You can even use it for SWLing. It can be used crossmode in SSB bands. You can use it in bed, as the designer does. It can be used in the dark or by sight impaired, as it will output all necessary info via morse code. I think in all other respects, the K1 is better at home or on car trips. The ATU option in the K1 will tune more antennas. KE6US has more info and opinions on his website. (See QRZ.com) The K1 has up to twice the output of the KX1. I would like an RF gain control and have even considered sacraficing the AF gain control to add one but that is just my operating style.

[Elecraft] KX1 vs K1
Hi All, I'm sure this has been covered before, but for hiking and backpacking is it a choice between the KX1 and K1, is one better then the other ? Or is it a nocontest and that the KX1 is the winner because of being smaller and lighter ? What about portable antenna's - a long wire ? or is their some thing as almost simple but better ? Cheaper ?

Re: [Elecraft] KX1 vs K1
Hi Bob - The KX1 gets the nod here. But for locations that I access by car, I like my K1 better. For that reason, I sold my KX1 and built another K1. I sold my first K1 when I built my KX1. I don't take a rig hiking much, due to we usually have a quick turn around time, and head back. If I want a hiking rig, I will use an SST. The K1 is a much more pleasant rig to use and has a performance advantage. There should be much more in the archives.
