[Elecraft] Just ordered a KX1, and have a question
Hello All: I ordered a KX1 and it was shipped Priority Mail on 7/23 and have not received it yet. Danged post office! In doing my preliminary research and preparation I have a question: Soldering is important, I think we all agree. The selection of the correct type and size is critical to success. Why isn't a hank of 0.31 dia Kester 44 included with the kit? I know, this would increase cost. But I would gladly pay an additional $3 for a kit to avoid having to buy a $25 roll of Kester. (and only use 1% of it) Anybody remember Heathkit? They were the premier kit maker of their day. Solder was included. Remember the nut starter tool? (I may still even have one!) Not to mention a plastic IF can tweeker. It was a nice touch from the top maker of kits. Its why we all remember them fondly and sorta miss 'em. I'm not trying to be cheap. Just a practical suggestion. I'm not saying Elecraft should supply flush cutters, common tools, and spoon feed us. Just that solder selection is pretty danged important. And isn't it like a component? It stays on the pcb just like all the other parts? For what its worth. 73 Marty / W4MY Park yourself in front of a world of choices in alternative vehicles.

Re: [Elecraft] Just ordered a KX1, and have a question
Marty, First of all, I believe .031 solder is too large a diameter for use on Elecraft products, especially the KX1. I use .015 with great success, and I do not recommend a larger solder than .020 for the KX1. The reason is that with the large diameter solder, there is not great control over the amount of solder applied - by the time the solder is molten, there is already too much on the connection. Just enough solder to fill the plated thru hole is adequate, although I like to see a very small fillet of solder with the edges of the solder tapering down to zero thickness on both the solder pad and the component lead to be certain everything has received adequate heat during the soldering process. See the soldering tutorial on the Elecraft website if you have any questions about what I am describing. Also, the 44 flux is a highly activated flux, there also seems to be a lot of flux residue when using it for soldering. The Kester 285 mildly activated flux is much better on untarnished components because it leaves the board cleaner - save the highly activated solder for working with components that have acquired a bit of corrosion and need the higher activity. OK, so you have some Kester 44 .031 solder that you would like to use on your KX1 - fine, use it, but be aware of the cautions about the amount of solder. If you find too much is applied, use solder wick to remove some of it. OTOH, If you are buying solder for the KX1, I recommend the Kester 285 in a .015 diameter (Multi-core is a great solder, but may be difficult to obtain). Many areas of the KX1 are quite dense with components and more care with soldering is required than for most of the other Elecraft kits. That does not answer the question of why Elecraft does not include solder with the kits like Heathkit used to do - I can't answer that, but I can offer some cautions based on my experiences repairing the KX1 - some builders have trouble because of inadequate heat when soldering (700 to 750 deg F is the best) and the application of too much solder are often encountered problems here. I have 'fixed' several KX1s by simply removing the excess solder and reheating the connections - that process takes about 2 hours to complete, so you figure the cost of a 'repair' caused by sloppy soldering - good solder is cheap by comparison. 73, Don W3FPR Marty Young wrote: Hello All: I ordered a KX1 and it was shipped Priority Mail on 7/23 and have not received it yet.

Re: [Elecraft] Just ordered a KX1, and have a question
David: You have to draw the line somewhere. I realize this. My thesis was to draw it a little further north to include solder, thats all. Strictly in the vein of nice touch department. Your soldering iron, lamp and hand tools are not part of the kit. Solder is. That's where I'm coming from. Maybe its kinda grey (pun intended). Elecraft made its decision on how thy wanted to handle this, and that's their perogitive. Maybe half would use it, half would not. I would, you wouldn't. There, that proves it! To Elecraft marketing folks: I'd appreciate some solder.

In fact, I was glad I bought a full roll...so I don't have to worry about ordering another right away! But then, if the K2 kit had included the $125 soldering station I bought, the magnifying ring light, the board holder, electrostatic soldering mat/wrist band and the desoldering iron maybe my XYL wouldn't roll her eyes every time I talk about how much I saved by building the radio instead of buying one already built! And, she sometimes subtly brings up things like the tower now on the side of the house, the rental of a hammer drill to punch a hole into the basement for the antenna wiresetc. etc. etc. David King KE7EKA Marty Young wrote: Hello All: I ordered a KX1 and it was shipped Priority Mail on 7/23 and have not received it yet.

Re: [Elecraft] Just ordered a KX1, and have a question
Hi Marty, At the time I built a Heathkit DX 20 in 1957, and when several friends built Heathkits in that era up to 1960, I don't remember any of us getting solder with our Heathkit. I bought Ersin Multicore solder and used that for all my kit building, and still prefer it after some 44 years of building research electronics. Solder is like beer and cars. Folks have their own preferences if they have built anything at all for awhile. No one size of solder is really adequate for all parts of kit building. For example, you might use a small gauge on parts on a small board, but a heavy gauge solder to make up type UHF Coax plugs. Where do you stop in providing solder? Do you then provide the flush cutting pliers to get folks to uniformly trim their component leads, the needle nose pliers, the soldering iron? (Now there is another personal preference item kind of like personal hunting weapons!) I think Elecraft does exactly what the majority of kits have done since the 1950's. They provide the electronics and the instructions, and the builder provides the tools and solder. Those few kits I have seen with solder had types totally unsuited IMHO, for the job. The type of solder one uses affects how well the finished kit looks. There are some solders that are just adequate, and others that have superiour wetting, and flow characteristics. -Stuart K5KVH - Original Message - From: Marty Young [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Monday, July 30, 2007 3:17 PM Subject: [Elecraft] Just ordered a KX1, and have a question Hello All: I ordered a KX1 and it was shipped Priority Mail on 7/23 and have not received it yet.

Re: [Elecraft] Just ordered a KX1, and have a question
Man, Oh, Man Don you said it right. I was so ignorant when I got back into soldering, that i was not aware of the different sizes of solder. I had and still have it... the .031 solder.The last kit I had built was a Heath Kit HW12 in the 60s. So to practice some soldering I ordered one of the in-expensive receiver kits from Ramsey. Using the .031 solder I totally destroyed the Pc board! g Now, I have all kinds of rolls of .015 solder and use it for practically everything. Also have some what I think is .022. I have a soldering station and use it at 700 F.degrees. Paul Gates, KD3JF Having 2 cataracts one on each eye I was smart enough to have Jerry McCarthy build my KX1 and later he added the 30/80 module for me. Today I passed the eye test for renewing my drivers license by the skin of my teeth so to speak. The License is good for 5 years so I am sure during that time the cataracts will be big enough so I can have them removed. I have no problem seeing in the daylight and do not drive at night.

Re: [Elecraft] Just ordered a KX1, and have a question
My experience is different, which is just more evidence to support using the solder you prefer. I routinely build surface mount boards with lots of fine pitch parts (like K3 prototype boards :-) using either 0.031 or 0.025 diameter solder. I never use anything finer. YMMV 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
