Dave, There are a number of online resources to help ease the pain of SMT soldering/desoldering. If you have access to older QRP magazines, there were many tips in them. AMQRP.ORG has useful info online. This document covers a lot of ground and may be helpful:

Went to install the HAGCMDKT kit on #311. Interesting but all was already done except for shorting R33 and R40. Maybe there were interim fixes for this mod? By the way, C222 had already been changed to .1 uF for the CW Keying Rise Time Reduction. I needed to add the RXA board to the KXV3.

Re: [Elecraft] K3 - HAGCMDKT mod kit

I installed the HW AGC mod yesterday on K3 325, it was not fitted. I opted for the SMD components, and all went fine but I decided to use the standard LED as I was unsure of the cathode marking on the supplied SMD LED. This ought to be indicated on the instruction sheet I think. Also fitted the

Hi Tony, Nothing was required on your part. That is the factory version of the change that already has very low value SMD resistors installed for R33 and R40. 73, Eric WA6HHQ N2TK wrote: Went to install the HAGCMDKT kit on #311. Interesting but all was already done except for shorting

Hi Everyone, I own K3 #371 and have entirely delighted with it and the Elecraft experience to date. But I do have a small nit to pick with the HACG mod and some comments posted earlier today. After doing a lot of pre-modification research on my #371, I determined that the mod had been

Re: [Elecraft] K3 - HAGCMDKT mod kit

Hi Dave, Dave you indeed had an unfortunate experience! After doing a lot of pre-modification research on my #371, I determined that the mod had been done, only partially, before it was shipped to me. The R33 and R40 were still in place and not removed or jumpered as the mod instructed.
