Wow Don & Ron, I'm shocked. Such heavy hitters coming down so hard against the Rework Eliminators (RE).
As a novice builder, I built a bare-bones K2 with full RE. I spent the time going through the RE instructions and writing changes into the K2 manual prior to beginning the kit. Then I just followed the red-lined K2 manual for building and aligning. There were NO issues. Everything worked first time. No funny alignment stuff that I recall. Just smooth. Since then I've added the AF option. I unplugged the header board, plugged in the KAF2 and was up and running with no additional mods to the K2 boards. I recently swapped the AF for the DSP. Again, it was plug and play. Now I've removed the DSP and am again operating the rig with just the header board. Without the RE, what would I have done? First, I'd have to rework the K2 to add the parts for the KAF2. Then, after deciding I don't want to use either the KAF2 or the KDSP2, I'd have to either rework the board to remove the parts I added or I'd have to dangle a jumper wire across pins on the connectors. I don't like either of those approaches. The other approach is I just leave the KAF2 in there in bypass mode. This is what I suspect most K2 owners do. Buy an option, install it, never take it out. I also added the SSB option. For K2 mods, I had to rework two crystal grounding leads and had to put the shorting jumpers across the mic configuration header. That was it. KSB2 plugged in and is working fine. If I decide to be CW only, I can swap the SSB module for the header boards and I'm in business. I'm part way through the KPA100 build and so far, every single K2 mod that the manual has called for I've been able to skip since those steps were done during the initial K2 build. Certainly I don't have the experience or credibility of you two gentlemen, but I do have my own experience, and for me and my needs, as far as I can tell so far, the Rework Eliminators have been money very well spent. - Keith N1AS - - K2 5411.ssb - -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ron D'Eau Claire Sent: Thursday, November 30, 2006 2:12 AM To: [email protected] Subject: RE: [Elecraft] Rework Eliminators Anyone building a K2 with the rework eliminators should read carefully Don, W3FPR's warnings about how installing them will cause you to have to make extensive changes to some of the K2 test and alignment procedures. If you want to remove a module at some point it's "dirt simple" without the rework eliminators. It involves fashioning a jumper or two out of some old clipped resistor leads to fit in the open connectors left when you pull the module. In one or two cases, the jumper is made with a supplied fixed capacitor. My S/N 1289 built in 2000 has been torn down and rebuilt so often I've lost count. It's been a test bed for a number of the K2 mods and improvements over the years.
