Re: [Elecraft] Getting ready to order a K2 - which options
The ATU, in addition to ATUing, adds a second antenna socket. The 160/RXant option adds 160 meters and an RX antenna socket, along with the firmware to receive on the RX ant and automatically transmit on another. Some find the noise blanker to be important.

Re: [Elecraft] Getting ready to order a K2 - which options
Burke, It depends on what you want to accomplish with your K2. Yes, the KSB2 will allow you to use digital modes - the K2 also has a 3rd set of filters that can be set up called the RTTY filter set (turn it on or off in the secondary menu). The K160RX adds a receive antenna and the 160 meter band. The K60XV option adds 60 meters and a transverter interface. The KAF2 adds a peaked audio filter that is very nice for CW. The KDSP2 (which goes in the same place as the KAF2 - you can't have both) adds audio DSP to provide brick wall selectivity as well as Noise Reduction. The KNB2 works well with impulse noise (like auto ignition noise) if that is a problem at your location. The KIO2 allows you to control the K2 from a computer or use an automated logger. That is the list unless you want to consider the internal battery or the tuner or the KPA100 73, Don W3FPR On 9/13/2012 3:22 PM, Burke Jones wrote: > I am getting ready to put in an order for a K2 kit.

Re: [Elecraft] Getting ready to order a K2 - which options
I built mine with no options, later added the KSB2 board. Have never missed having other options, though may soon build the KPA100. Suggest building what you've mentioned and using it for awhile. You'll have more than enough solder melting to complete what you've mentioned.

Re: [Elecraft] Getting ready to order a K2 - which options
If this your only base rig I would order the KPA100 that will give you a lot of operating options with the added wattage and still turn down to QRP if you want I do so with mine quit often. The KAT100 is a very nice tuner and tunes high SWR loads I prefer the external enclosure on mine. One thing I would suggest "strongly" is to consult with Don and ask him to advise you of the options and the order of installation as some can be done during the build. Otherwise you will disassemble much of the radio to install some of the options. On the other hand some are easily done after the build is completed at any time.

JMHO I'd suggest the "Rework Eliminiator" K2 Option Bypass Headers: http://www.eham.net/reviews/detail/6372 They work very well. You build the option bypass headers, and then when you build your K2, you build it as though you are installing every option. Many options require that you remove a component or two from the main board, so you just don't install those components at all during the build. For the options you don't actually install, plug in the option bypass header. Later, when you add an option, simply unplug the bypass header and plug in the option. 73, Wayne Conrad KF7QGA __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Getting ready to order a K2 - which options
If you do use the "Rework Eliminators" (or often called "unPCBs") I recommend you do *NOT* install the one for the K60XV - wait until you actually have the K60XV option in hand. Why you may ask - well, the change of the C71 value modifies the PLL voltage range drastically. With the K60XV installed, the lowest voltage which must be adjusted for occurs at 5300 kHz, and if one does not have the K60XV in place, the K2 will not tune to the 60 meter band - so you have to guess about the low voltage point, and remember to revisit it when you do put the K60XV option in. It might be OK to install the headers, add the coax on the bottom of the board and install D19 and D20, but do not change C71 until it is time to install the K60XV. I just worked on a K2 that was sent in for repair because the owner did not know to turn the D19 menu parameter to "y" - the rework eliminators had been installed and he did not know that either (he had just bought the K2). So he endured the cost of repair and shipping just because of a simple menu entry - don' change C71 until you have the K60XV in hand. 73, Don W3FPR On 9/14/2012 12:30 PM, Wayne Conrad wrote: > On 09/14/12 02:19, Fred Smith wrote: >> One thing I would suggest "strongly" is to consult with Don and ask him to >> advise you of the options and the order of installation as some can be done >> during the build.

Re: [Elecraft] Getting ready to order a K2 - which options
This thread is the first I've heard of this rework eliminator. It sounds interesting but I can't imagine that working on K2 upgrades is that daunting, is it? Granted, I didn't build my used K2 but all I've heard is that the process is very straightforward with Elecraft's excellent instructions. I'm about to upgrade my early model to the latest version myself, and was going to just plow through the stages one by one (I already have all the upgrade parts). Would there be any advantage to this rework eliminator at this stage or is that designed for upgrades "to be done at a later date"?

Re: [Elecraft] Getting ready to order a K2 - which options
Bill, Ask yourself how many additional options are you going to add to that K2. If the answer is none or few, forget the Rework Eliminators, they are a waste of your time and money. The Rework Eliminators only make sense on a new K2 build when you are undecided about the option set that you want, or want to do a basic K2 build now and order the options later. 73, Don W3FPR On 9/15/2012 1:21 AM, Bill Tubbs wrote: > This thread is the first I've heard of this rework eliminator.

Re: [Elecraft] Getting ready to order a K2 - which options
If I were to do do a new K2 build again, I would definitely incorporate the Rework Eliminator kit in the initial build. I added two options to the basic K2: (1) the KPA100, which required (IMHO anyway) an annoying dissasembly of the K2 to add two connectors to the main board and (2) the KSB2, which should have been an easy add on, but I had difficulty, even using desoldering braid, in removing main board jumpers. So, if I had known about the Rework Eliminator kit and what was involved in adding options, I would have incorporated it in the initial build, even for just those two options. But I agree that it probably wouldn't make sense to retrofit the kit into an existing K2. - Bruce - Bruce Rosen K1FFX K2/100 6982 KSB2 -- View this message in context: http://elecraft.365791.n2.nabble.com/Getting-ready-to-order-a-K2-which-options-tp7562628p7562791.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
