Maybe it's just me, but seems the issue is the end of through-hole
components? In other words, it might be possible to revive the K1, but it'd be all surface mount. 73 -- Lynn On 6/6/2019 10:28 AM, Dan Baker wrote: > A K1 would provide us with a through hole kit. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

I thought the retirement of the K1 was due to parts being rendered as
unobtanium, which would more or less demand a redesign; would it not?

SMD soldering is actually pretty easy. It does take a good quality
soldering station to do it though.

Correct on both counts.
Trust me, as the designer of both the K1 and KX1 I have a soft spot for them and would love to bring them back. But several of the critical parts became impossible to source, and a substantial redesign would be required to work around them. The good news: the KX2 is soooo much more radio, in a smaller package. We had to go through the K1 and KX1 to get to the KX2, and we're not looking back :) 73, Wayne N6KR > On Jun 6, 2019, at 10:49 AM, rich hurd WC3T <[hidden email]> wrote: > > I thought the retirement of the K1 was due to parts being rendered as > unobtanium, which would more or less demand a redesign; would it not? > > On Thu, Jun 6, 2019 at 1:28 PM Dan Baker <[hidden email]> wrote: > >> With the K1 talk I would like to propose, a thousand of us give a 50% >> deposit on a new run.

I agree. SMD soldering is actually much faster than through holes because
you don't have to trim leads. It is just a matter of getting used to small parts. Magnifying glasses will definitely be necessary for most of us. Reviving K1 with SMD parts will make a very trail-friendly radio. On Thu, Jun 6, 2019 at 1:53 PM James Doty <[hidden email]> wrote: > SMD soldering is actually pretty easy.

I miss the good ol' days, e.g. high school, when my quick 'n' dirty transceiver projects were built by twisting component leads together. No PCB, no chassis, nothing but raw parts. Hook up a 9 V battery and a shamelessly untuned wire antenna. Work DX. Repeat.

Yes, pretty easy, but not true that it takes any special or expensive
soldering station to do quality SMD work. In the winter months I do a lot of SMD work. I don't have a quality soldering station at all. I use solder paste from a small syringe, cheap tweezers, a $2 coffee cup warmer (WalMart), a small $25 heat gun used by scrapbook crafters (Michael's), and a regular desk magnifier lamp. For a few parts, I use tweezers and my regular Hakko soldering iron with a pencil point. Here's a video of the technique I've been using for nearly 10 years of the 62 years I've been a ham. https://www.youtube.com/watch?v=F0OKuxPiGKs If the link doesn't appear, google SMT Soldering Movie on youtube. A K1-level SMD kit would be no problem for anyone capable of attacking a thru-hole K1 or K2, but Wayne clearly addressed that possibility, and rightly so. The K1 may be dead, but not soon forgotten.

I have a decent soldering station, but for SMD beyond a few parts I don't
use a soldering iron. I use an i-Extruder pencil (a stepper-motor powered syringe dispenser) to apply dots of solder paste to the pads, then tweezers to pick-and-place the components. If it's a small area, I use my hot air station to melt the paste and solder the parts. If it's a larger board, I use a microcontroller-driven heating plate called a ReflowR to precisely ramp up the heat, melt the paste, and cool it off so as to cause the least thermal shock to the board or the components. I'm not nearly as good at the latter as I am with simple thru-hole components, or a few larger SMD components. 0603 and above, I do by hand if there's just a few. Most people suggest a "tack one end then get the other" approach, and while it works, I don't find it as efficient as I'd like. So I use the same i-Extruder to apply dots of Amtech "tacky flux". I place the components on the pads, held down by the tacky flux, then tack-solder one end, then the other. If it needs it, I go back and flow enough solder to make a good fillet, but frequently the tack makes a decent fillet with that good flux. That's how I built a Zachtek WSPR beacon a few weeks back. It had four low-pass filter stages, each with several surface mount components. It was few enough that I didn't think it warranted the reflow plate, though I did use the hot air pencil to clean up the fillets I did with my soldering iron. Came out looking really good, and working well. 73, Gwen, NG3P On Thu, Jun 6, 2019 at 2:33 PM rich hurd WC3T <[hidden email]> wrote: > Dead bug construction ROCKS. > > On Thu, Jun 6, 2019 at 2:02 PM Wayne Burdick <[hidden email]> wrote: > > > I miss the good ol' days, e.g. high school, when my quick 'n' dirty > > transceiver projects were built by twisting component leads together.

There probably aren’t more than a handful of folks who could actually build an SMD kit of any size without having to send it back to Elecraft to be built or to fix the mess.

Hi Grant,
There certainly were a lot more than a handful that build the NorCal 2030 that had a surface parts count close if not more that the K1.

That’s the key, of course. Most don’t have the right tools ... regardless, I think it would be a losing proposition since it would require basically re-engineering the radio ..

So true...
Eyesight and finger dexterity are the right tools as well. And, as it was so astutely stated - not everyone has the right tools. Let me add one thing - not everyone has the right tools in their peak condition. I used to dismiss this argument myself. Now I am ashamed that I did.

1/ It always seemed to me that this method heats up the components much more than using a simple soldering iron, where you can pause between soldering each pad to allow heat to dissipate.
2/ Is that a capacitor standing up at about the 1:12 mark? Not good.

I have serious issues with dexterity as a complication from a broken neck
in 2006. I've used sport lock picking as a form of occupational therapy. It has really helped me keep and improve my hand and finger coordination. That translates well to soldering capability. It's not perfect, but it's better than it would be otherwise. 73, Gwen, NG3P On Thu, Jun 6, 2019, 4:07 PM demindor <[hidden email]> wrote: > So true... > > Eyesight and finger dexterity are the right tools as well.

#1 would be true for thru-hole components. SMD components on a board in,
say, a K3 were ramped up to about 225 deg C (435 deg F) over SEVERAL minutes. They're designed to withstand those temps. I don't know what the little heat gun I use puts out, but it doesn't burn paper which famously burns at Fahrenheit 451. #2 It happens. When the solder goes molten, the surface tension moves parts around a little. Usually, it tends to position the part on the pads better than you can with tweezers on clean pads. Sometimes parts stand on end. Not a problem reheat it and push it down. Things don't always go perfectly on thru-hole either. Don Wilhelm helps people nearly every day with problems that turn out to be soldering related on K2's. They happen to everyone. Not a big problem. BTW, notice that the solder paste on the IC is not carefully applied to each pad. Instead, the solder is applied ACROSS the pins in two lines. When it goes molten, the surface tension positions the parts and draws up any solder bridges onto the pads. Doesn't always work, but I've done some large ICs that way without solder bridges. When it happens, dab the connection with an iron and the bridge disappears. Safe and easy. I understand not everyone has the eyesight or dexterity for it, and not for all sizes of SMDs. I avoid the very small stuff as do most hams who use SMD. Amateur radio is about new technical challenges whether building or operating. This is a very accessible and useful skill that can be acquired with inexpensive tools and a little practice.

Its a skill that one needs time and practise to master. I used to
run a home business building smd kits for others after a career as a component level technician where I did smd repairs. But the last generation of MOT intrinsically safe radios required a $10,000 school and a dedicated repair station to be qualified by MOT to do repair work. MOT instituted a flat-rate repair service for about $150 per radio which turned me into a troubleshooter and shipping dept. I retired a few years after that. I bought a Haako FX-951 repair station for that business and used a lighted magnifier. SMD assembly is much faster/cheaper and can be automated on a production line with better reliability than human-built. That's why todays tech does system troubleshooting to the board level and then board replacement. New boards are cheaper than paying the tech to repair them. Most commercial radio shops charge $100-$125/hour for servicing. Another ten years and there will no longer be component level techs. Very hard for a small business to compete using a human production line of solderers. Probably only find a small line to build pre-production units for testing/re-engineering. --------------------------------- There probably aren?t more than a handful of folks who could actually build an SMD kit of any size without having to send it back to Elecraft to be built or to fix the mess.
