Re: [Elecraft] P3 +12V mod for K3
My apologies gentlemen. Although the cable is shown in the illustrations (Fig 5 and Fig 7), showing that the KPA3 was removed with cable still in place, I failed to point that out in the procedure. Also, Figure 6, showing the recommended way of loosening the KPA3 connectors, was taken of a K3 without the sub-receiver and AUX antenna input so it does not show the cable. I can see how that was confusing. As Brian found, removing it adds a lot of steps to remove the KIO3 board along with the two pony boards from the rear panel unless it's used to connect the subrx aux input to the KAT3. The cable has enough slack to slip it around the KPA3 board as it is removed and replaced. Often that slack is in the form of a loop between the KRX3 module and KIO3 board that needs to be pulled into the KPA3 enclosure. 73, Ron AC7AC -Original Message- Did the +12V mod to my K3 with Sub RX yesterday. As you say the instructions did not mention the Aux cable, however I found that moving the cable to the rear of the K3 and then extracting the PA towards the front was no problem. Just needed to take care. 73 Stewart G3RXQ On Fri, 18 May 2012 19:28:51 +, Brian Alsop wrote: Did two of these today. One had a subrx. One did not.

[Elecraft] P3 +12V mod for K3

Re: [Elecraft] P3 +12V mod for K3
Brian, I did one for a friend a couple weeks ago - yes, I found the same thing, but decided to leave the cable in place and work around it (no bent pins) - it did work, but it was touch and go for a while. Yes, the manual should mention it - and I agree, the easiest way to remove that cable from the SubRX is to get the I/O board out of the way, although it is possible to remove the cable with the KIO3 in place - but plugging the cable back in with the KIO3 in place is a bit of a challenge (but not impossible if you hold the connector with pliers carefully). 73, Don W3FPR On 5/18/2012 3:28 PM, Brian Alsop wrote: Did two of these today.

Re: [Elecraft] P3 +12V mod for K3
Brian, I was able to do my K3 (which has just about everything in it) by simply removing the back bottom cover, the rear fan plate and the ATU. I left everything else installed. Since mine also has a K144XV, I simply let fan plate carefully dangle while I pulled the old components out and inserted new the replacements. Although a vacuum desolder station was available to me, I just used SolderWik. There are probably 6 different ways to do this, I'll pass your findings on to our tech writer. Thanks and 73, Paul alsopb wrote Did two of these today. One had a subrx. One did not. Instructions didn't mention that the subrx aux cable interferes with pulling the K3's amp module.

Re: [Elecraft] P3 +12V mod for K3
Everyone probably already knows this, but if the solder doesn't wick easily out of the hole, add a little fresh solder first. This made all the difference with the board in the K3.

Re: [Elecraft] P3 +12V mod for K3
De-soldering has many possible facets, and which one you use will depend on your experience, tools available and to a certain extent the amount of stubbornness you want to tolerate. Each connection is different. I routinely use a Hakko 808 desoldering iron, but there are times when a slender tool (narrow tipped long screwdriver) will do a good job of prying the component up off the board, and the 2nd lead can easily be removed - for multi-legged components that process can be much complex.
