标题：KX3对于初入门的初学者是否是一个好的选择？

以下是N6KR回复的邮件内容：

Interesting thread. The dust appears to be settling, so I thought I'd weigh in. Whether I'm biased or not is left as a study question for the reader ;) 

帖子很有意思。尘埃终将落定，所以我想我会来权衡利弊。但是我说的到底是客观的还是略带偏见的，这个问题交由读者来考量吧。 

We designed the KX3 specifically for new hams. Here are some considerations: 

我们设计KX3的时候特别针对了新HAM的要求。这里有一些设计考虑：

- The KX3's size and weight allows it to be used anywhere, and powered from a small battery or power supply, even its internal battery pack. This means you don't have to evict anyone from precious desk or table real-estate as you dabble in your new hobby. At least not right away. You can move around, maybe use a corner of the garage, or an RV, or a picnic table. This is why we call it "ultraportable." 
-KX3的尺寸和重量轻盈，可以在任何地方使用，可以用小电量的电池或者小功率电源来供电，甚至他内部的电池盒都可以让他很好的工作。这意味着当你有这样一个新的爱好的时候（无线电），你不需要清理你桌子上的任何空间来摆放他。至少不需要立即清理出一定的空间来摆放。你可以带着它四处移动，甚至在你车库的一角，或者野营车里，或者一个野餐桌上。这就是我们为什么定义为“超级便携”的原因。

- The KX3 has about half as many controls as the K3 and other full-featured desktop radios. We kept only the essentials. And you don't need to use all of the rig's features. You can start with the basics -- VFO, AF GAIN, MODE, BAND up and down. The default settings of the radio pretty much just work. Set the power level you want and start tuning around. 
-KX3电台拥有相对于K3或者其他全功能桌面电台一半的控制功能。我们只保留了必须的功能。并且你并不需要全部的那些特征。你可以从最基本的开始-频率模式、射频增益、发射模式、波段上下调整。电台的默认设置已经可以让它完美的工作运行的了。设置好你所需要的发射功率您就可以开始四处调频了。

- The owner's manual is written with new hams in mind, with supplemental information about antennas, operating modes, and the nature of the different HF bands. We don't go into a huge amount of detail, but it's enough to get you started, and you already have a few thousand friends on the Elecraft and KX3 reflectors if you want to dive into deeper waters. The manual is organized so that basic operation is covered right up front. As time permits, you can try each more advanced feature. 
-操作手册在编辑的时候就考虑到了新手HAM的水平，在操作说明中加入了关于天线、操作模式、还有HF波段本质的补充说明。我们并没有描写大量的专业细节，但是已经足够可以让您使用上手，并且如果您想更加深入的了解，目前已经有成千上万使用KX3的朋友的反馈可以供您参考。

- At 12 W (8 to 10 on the highest few bands), the KX3's power output is only 9 dB below 100 W. Thanks to the beauty of logarithmic phenomena, that's only 1.5 to 2.5 S-units depending on whose S-meter standard you're basing it on. (We use roughly a 5-dB-per-S-unit standard at Elecraft.) Yes, it can be harder to work stations using SSB mode when you're two S-units down, but if you avoid pileups and stick with calling stations that are well above the noise level, you'll have no trouble making SSB contacts. 

-最高12瓦的功率（在最高段的几个波段是8-10瓦），KX3的功率输出仅仅比100w的状态下少9DB。应该感谢漂亮的对数现象，如果对方使用的标准S场强表，那么这将在对方的接收S表上仅仅少1.5-2.5个S强度。（我们在Elecraft上粗略的使用每5个db为一个标准S表信号单元）。是的，在少了2个s表场强的情况下，使用SSB语音稳定通联可能比较困难，不过如果你避免拥挤的信号堆栈，你的信号将会远高于背噪，进行SSB通联是没有任何问题的。

- The KX3's wide-range ATU can greatly simplify the process of erecting antennas for all bands. Here's the simplest case: One piece of wire about 25 feet long, tossed into a tree, and a similar wire laid on the ground, can be connected directly to the radio with a BNC-to-binding post adapter (no coax). The ATU can tune this on 40-6 meters. If the wires are 50 feet long, you can also cover 60 and 80 meters. That's 80-6 meters with two wires, no coax, and a support provided free by nature (or your neighbors). Obviously you can improve on this to better your odds, say by using an off-center-fed wire of 50 to 100 feet long supported in the middle by a 20 to 40 foot pole or tree and fed with twinlead or ladder line. A balun (e.g. Elecraft BL2) would then be used at the rig to convert this sortof-balanced antenna to the radio, through a short length of coax (1 to 2 feet). 

-KX3的高效全波段自动天调，可以很轻松的使得装配的天线工作在任何波段。这里有一些最简单的案例：一条扔到树上的25英尺长（7.62米）的导线，另外一条相似的长线铺平在地上，可以直接通过BNC天线安装器链接到电台上，而不必使用馈线。内置的自动天调可以使得长线谐振在40-6米波。如果这个导线可以到50英尺长（15.2米），你就可以覆盖到60和80米波。这是由两条导线直接链接，不需要馈线，可以覆盖80-6米波段的天线，他可以完全融入自然环境中（或者融入你的邻里之间的环境）。显然你可以改进这个天线来增加你通联的胜算，比如使用一条偏心馈电点的50-100英尺的长线，由20-40英尺的支撑杆或者树木支撑，并使用双芯引线或者梯形线。在电台和天线之间将会使用巴伦（比如Elecraft BL2）来将这天线转为平衡天线，需要一条短的馈线来连接巴伦和电台。

- Hams who are transitioning from VHF/UHF to HF might want to add the 2-meter module (3 watts, all modes, including repeater controls, DTMF, memories, etc.). When you get tired of exploring the vast wilds of the HF bands, you can return to the familiarity of 2-m FM, etc., and chat with the locals. 
-那些正在从VHF/UHF过度到HF的HAM可能想增加2米波模块（3瓦功率，全模式，继电器控制，支持DTMF，记忆功能等）。当你在疲于在广袤的HF波段探险的时候，你还可以转回到2米波FM状态，或者其他模式，和本地朋友聊天。
