The Linus Special
Locked
 
|
Hi All,
Notwithstanding my dog Linus's efforts to the contrary (trying to eat my parts), the T1 is up and running. Still running tests though, but it tunes fine. My firmware is v 1.07--looks like there has been an update since the manual was prepared. The only construction question I have is why we are instructed to wait until the board is full of parts before we do the parts on the bottom side of the board. Seems like it would have been easier to mount these first, still solder them from the bottom side, but then clip the leads flush on the top side. But I'm sure there's a good reason for doing it otherwise. The T1 is going to be a very handy piece of gear. Thanks to Wayne and Eric for another winner. Happy Easter to all who celebrate the day.

What in the operating manual makes you suspect something different? Wayne wrote the owner's manual and I confess I haven't studied every statement in it for accuracy. Maybe a 1.07 change got missed that should be fixed. Thanks for the input on the assembly manual. That was my responsibility. I, too, prefer to mount parts while I can easily flush-cut the leads on the opposite side, but doing so in the T1 would likely cause interference with installing the relays. Both bottom-mounted caps end up right against the relay pins on the underside of the board after installation. We thought it would be easier to install the relays and to make sure they were all straight and properly seated against the board and all the pins were soldered before other parts are added. Since the bottom-mounted parts are also soldered on the bottom side, it didn't seem like it would be difficult to install them after the relays were in place. Putting them in last avoided any chance of breaking the capacitor leads by bending them back and forth to allow access to solder and inspect the relay pins.

Wayne missed where he used ver 1.06 as an example of how the firmware revision is reported. Yes, Wayne went to a 1.07 just before production started. Thank you for the nice words about the assembly manual. This is the third such manual I've written for Elecraft, and let me say that it is *not* the product of my own fingers, but rather a very concerted team effort. At least a dozen people had input into that assembly manual. It starts with the engineer, of course. In this case it was Wayne working out the electrical and mechanical design, always thinking about the person who will ultimately build the kit as well as use the finished unit. Designing something others can build makes a project much, much bigger than just making it work well! When the design is getting close to a final product, it's my turn to build one. I get the schematic, notes the designer has made about tricky parts of the build, and a box of parts. As I build the unit I take photos, make drawings, document the steps and analyze the build process. Some engineers who also do a lot of writing, like Wayne, also provide a lot of notes, which makes my job go faster. My goal is to get a complete assembly procedure together in time for the field test. The field testers then get the manual and the field test "kits" of parts that are close to what we plan to deliver to customers. They build their units and comment on all aspects of the design, assembly procedure and performance of the unit while the engineer and I take careful notes. I'm constantly tweaking and revising the manual to correct any errors and to make the process clearer each step of the way. The engineer is watching closely for any design issues that need addressing. That's where emphasis on certain issues, like making sure the LED's are installed correctly, are identified and warnings included in the manual. Sometimes, when significant design changes occur, I do another build. I think I built two KX1's and 3-1/2 XV transverters before the engineers and field testers were happy with the product and I was happy with the manual. All the time the manual is constantly being updated and corrected and reviewed. Finally, then, the product shipments start and, as you've probably noticed, I'm hovering around the reflector looking for comments about the assembly procedure in case a mistake slipped by. So the manual, like the whole design, is really a huge team effort. I'm pleased to be a part of a great team who works together very well. And, by now, I'm sure that you've noticed that, as a customer taking the time to make a comment, you've become a valuable member of that team as well. From what I've seen, no Elecraft product is ever truly finished. Each one is carefully scrutinized by users everywhere and feedback is taken very seriously. Whenever a design change or improvement is called for to ensure the device works as advertised, it's made without hesitation thanks in large part to the rest of the design team: all the Elecraft owners who ask questions and offer feedback. Thanks Dave! Enjoy the T1! Ron AC7AC _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.

I would like to assure all, the very latest version of the firmware as
of today (03/29/05) is 1.07. How would I know? I batch burned the chip you installed in your kit. Brian Broggie - W6FVI Elecraft Parts [hidden email] wrote: <snip> >fine.
