30-Mar-08 - RF Board Assembly Continued
Life has been getting busy for me now that spring is here. The kit build was interrupted while I prepared to host a family gathering for Easter. However, before this I managed to install much of the remaining components on the RF board. Thankfully, there were no additional missing part issues. No really notable component challenges for this round - just a ton of resistors, capacitors and a few transistors to install. Elecraft does not instruct on whether to install and solder one component at at time or not. I decided to solder these components one at a time because of how crowded the board is getting. I think this was the right way to go.
Now I am at the final stages of the RF board assembly. Elecraft reserved a large number of toroids for the end of the kit. I have wound all the band pass filter toroids and installed them. I am currently working on the challenging double wound T2 core. I wound it incorrectly the first go. Subconsciously I must have known T2 was wrong because I spontaneously decided to recount the windings after I installed it. So, after discovering that I was short a winding, I had to uninstall - a total pain - and T2 is now waiting to be re-wound. After T2 is re-done, there are only a relative few more components to install, and I am done! Here are front and back pic of the board just before I started on the pass-band filter windings:
