Here is a summary of the KPA100 + KAT100-2 discussion as I last tracked it (I am hoping to do this myself some day). If there are any corrections ro additions I would appreciate note of them.
dt . ==== --- "David Toepfer" <[EMAIL PROTECTED]> I was wondering how I could build a K2 and keep it light and QRP portable without having to actually remove the amp every time I wanted to move it. Puting a KPA100 and a KAT100-2 in EC2 case, is that possible? --- "Bill Flynn AIØC" <[EMAIL PROTECTED]> Lyle Johnson, KK7P (ex-WA7GXD), has done this. He's written it all up on an excellent Web page that you can view at http://www.fidalgo.net/~wa7gxd/k2kpa100.html. --- "Paul Clay" <[EMAIL PROTECTED]> Has anyone implemented Lyle Johnson's (KK7P's) suggested method (see http://www.fidalgo.net/~wa7gxd/k2kpa100.html#NOKIO2) of running a K2 and KAT-100 combo without an installed KIO2 (or KPA-100)? --- "Sverre Holm" <[EMAIL PROTECTED]> The question of the KPA-100 external to the K2 surfaces from time to time, and there are two descriptions of how it can be done. To find them you may check the Unofficial K2 Modifications page at www.qsl.net/la3za/K2/mod.html, go to General mods and then KPA100. --- "Tom Hammond" <[EMAIL PROTECTED]> Please visit: http://www.fidalgo.net/~wa7gxd/k2kpa100.html For (I think) all the info you should require on this subject --- "Don Wilhelm" <[EMAIL PROTECTED]> Yes, it IS do-able and has been done. In fact, I just received my EC2 enclosure and am about to do it myself. Check out http://www.fidalgo.net/~wa7gxd/k2kpa100.html to see how. In addition to the external enclosure, you will need the KIO2 option in your base K2 so it can communicate with the external KPA100. --- "Bob Nielsen" <[EMAIL PROTECTED]> Is it recommended to integrate the KPA100 with the K2 and get it all working together before remoting it in the EC2? --- "Lyle Johnson" <[EMAIL PROTECTED]> In the initial KPA-100 checkout, I had mine laying upside-down on a thick book (must have been a Windows tome...) with the cables plugged into the open-top K2. Once the KPA100 is checked out in this fashion, cal done, etc., I don't think it matters which box you put it in. --- "Eric Manning" <[EMAIL PROTECTED]> YES! That way, if any little glitches pop up when you remote the KPA-100, you can eliminate a lot of possibilities up front. For instance, if there are communication problems when it's remoted but it's OK when in the single box, you can focus on the RS-232 path between the two microprocessors . It's just the same principle of building a piece of the kit, then testing it before building any more, which Elecraft always follows. --- [EMAIL PROTECTED] My question for those who have gone through this is if there is a recommended order of construction that makes integration and/or check-out of the various components easieror more logical. --- "Lyle Johnson" <[EMAIL PROTECTED]> Yes, 1) Build the KPA-100 into the K2 and see that it works. 2) Build the KAT-100 in the EC2 case, connect it to the K2/100, and see that it works. 3) Build the KIO2, remove the KPA-100, and verify the K2/KAT-100 combination works. 4) Put the KPA-100 into the EC2 with the KAT-100 and verify it all works. --- "Don Wilhelm" <[EMAIL PROTECTED]> Yes, do the KIO2 first, but check out the instructions for mounting the KPA100 in the EC2 while you are building it - the inductors on the KIO2 connector/header board must be changed to toroids or other chokes that will carry the additional current. Other than that, I can think of no other particular order, but you may want to build the KPA100 before the KAT100 so you can check out the tuner at full power. --- "Bill Acito W1PA" <[EMAIL PROTECTED]> fyi, consensus (6 or 7 emails) seemed to be if you want to swap back and forth from a QRP to the 100W version of the K2, then mounting the KPA100 (and KAT100) in a seperate EC2 is the way to go. Most (not all) who responded found swapping the lids tedious, and dangerous (possibly dropping a heavy lid into the K2) --- "Bill Acito W1PA" <[EMAIL PROTECTED]> Yes, and was still described as faster and safer. http://www.qsl.net/la3za/K2/modAny.html#KPA100 --- "JEAN-FRANCOIS MENARD" <[EMAIL PROTECTED]> Now I have updated my website about building a KPA100 and KAT100 in the same enclosure, as advertised by Elecraft with the KAT100-2.
