Re: [Elecraft] RE: K2 with USB anytime soon??
Right on. That's how USB connectivity was incorporated into our latest product line. The FTDI part interfaces with a UART on the microcontroller on one side, and a normal USB host port on the PC. FTDI furnishes a USB driver and an application level DLL which our PC hosted control software calls into to move data into and out of the interface. We bit the bullet and signed on with the USB consortium to get our own Vendor Id number. The hardest part is figuring out how to manage the EEPROM holding the USB device descriptor and checksum, so as to give the FTDI part it's new identity (documentation was sketchy). Also the distribution of the driver, application DLL, and .inf file had to be worked out, as was the management of USB serial numbers in mfg. But really no big deal, the investment in the serial protocol is preserved, and no USB driver needs to be written from scratch. Anyway, the FTDI part makes tunnelling an existing serial protocol through the USB port easy and our customers are happy since they can use USB natively on their new laptops without RS232 ports. They hate converters since the use case is temporary setups in the field for maintenance and diagnostics - they want a minimum of cables and whatnot to lug around and fuss with.

Well, you need several selectable filters, because you need to reduce the low-order harmonics. The usual lowpass TVI filter cuts off around 30 MHz or even 50 MHz. But you need to eliminate the 14 MHz (etc) harmonic that goes with your 7 MHz desired signal. A tube rig doesn't have this problem because the tuned plate tank circuit has enough selectivity to reduce these enough. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] What's wrong with Serial
It seems to me the glaring error with Elecraft's serial port implementation is the ability to blow the I/O card out of the water if you use anything but the "special" K2 serial cable. They should have designed it so you could use an "off the shelf" serial cable. Way too much damage exposure. Really seems out of character to the rest of the rig options. 73, Paul ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Duplicating the KPA100 LP filters
I have a very nice well-built Henry Radio 100B solid state amplifier. Like the KPA100 it uses a pair of 2sc2879's to produce 100 watts. It has a heat sink and fan that looks like it would be enough for a KW! Unfortunately, it doesn't have built in LP filters so it can't be used to feed an antenna. I'm thinking about duplicating the KPA100 LP filter section so I can use this amp as an output stage for another rig. This sounds like a no-brainer, but I wonder if there's any reason not to do this? Also, does anyone know the manufacturer and model number of the relays (K3-K12) that Elecraft used?

[Elecraft] Elecraft CW Net Report for June 18th & 19th, 2006
Howdy Folks, We had two very good nets this evening. Twenty meters had QSB from East to West and it was a little light to me. Forty meters had it all: QRM from the Flying Pigs, QRN from a storm somewhere in the Midwest, and QSB would come and go throughout the net. Made life interesting ;) My faithful Co-NCS was hard pressed to find stations on twenty but made up for it on forty meters. Thank you Tom, I appreciate the respite where I can unscramble my notes. Between the two nets I made and ate dinner, finished the laundry, split some more wood, hauled, and stacked it. I did the dishes too just to keep myself busy. The sun is now out but the fire is keeping Sam and I warm. I hope the wood I've been stacking dries out as fast as possible because I may need it for the rest of the summer to keep the chill out of the house! Summer may actually get up here before the foxgloves start blooming. They are getting underway at 200 feet in elevation but none have started above 1000 feet. When the foxgloves have bloomed their way to the top of the stalk the summer is fading into autumn. It is a good time to cut more wood!

This total is from 420 different radio operators. It was nice to meet each and every one of you. However, I am sure there are many more folks who would like to try once they've built their KX1, K1, or K2. Some like to check in with each new rig they build just to see how they work ;) I've got quite a list of serial numbers too but I do not have a clean sweep of all of the folks who've participated. We are also two states shy of WAS ECN style. If you'd like to correct that problem please check in from Delaware or South Dakota the next time you pass through either of them. I wonder if we can get some more wall paper for the web site for 500 serial numbers? Until next week, Stay warm (or cool) and stay well, 73, Kevin.

RE: [Elecraft] Wayne...Eric...K2 with USB anytime soon??
Actually, I'm working on a USB interface for the K2. My prototype worked quite well. It only received but what I saw on the waterfall looked good. The part of the design I was most concerned about (USB) worked well. It's a compound USB device - hub with soundcard and serial port. I'm in the process of designing the first PCB that contains all the circuitry. The prototype I mentioned was bits and pieces of hardware strung across my workbench. No drivers other than what comes with Windows XP are required. Unfortunately, I haven't had much time to work on it lately. I have a consulting business (FPGA design) in addition to my normal day job and I'm deep into a Gigabit Ethernet design at the moment. Not enough hours in the day.

[Elecraft] #5514 K2 is born! Proper care of internal battery? Protective Carrying Case?
K2 #5514 is alive and well. After having wonderful experiences with the K1 over the past several years, I finally had the opportunity to devote nearly every minute of the past 6 days to building the K2 (basic QRP-CW). The rig went together nicely, passed every test, and worked flawlessly when completed exceeding specifications. Today, we took the K2 into the mountains using battery power to make the first QSOs on 40, 20, and 17-meters. The design and operation of the radio is a work of art! Thank you, Elecraft. Care of the battery: What is the proper technique to care for the internal battery? Will the battery recharge when the switch is off and an external power supply is connected? Should the internal battery switch be left on during the recharge? Will the battery be overcharged and damaged by leaving the internal battery switch on at all times with external power applied? Carrying case: Years ago I purchased a nice case for the K1 from Mountain-Ops Communications who seem to be out of business. Can someone recommend a nice protective carrying case for the K2? Is either a Pelican case or PowerPort Radio Box case a good choice? Thank you!

RE: [Elecraft] RE: K2 with USB anytime soon??
Fran brought out some good points. Thanks you Fran. I'd like to take it a bit deeper. Technically Elecraft could develop a set of USB based rig control semantics that allowed end user programs (loggers or just simple rig controllers) to use the Windows native HID (Human Interface Device) USB API (Application Programming Interface). Other ham radio programs have done this. But it's really a bit of a hack and often falls short of what the programmer was trying to achieve. On conjecture, let's assume that Elecraft wanted to do it the right way. They would have to develop a native "kernel mode" USB driver unique to the K2 that would be inserted into the "I/O stack" above than the raw USB protocol driver. Realistically this could be done for Windows. It probably would not be done for Linux or the Mac. Well, now they've gone beyond just doing firmware that runs inside the rig to supporting an OS driver(s). And they would probably want to change the PIC chip on the KIO card to be one with the USB serial engine built on board - more design and firmware coding. It could be done but it would be a major effort. If they are doing it right they will spend upwards of $2000 (every two years) to get a registered "USB vendor ID" from the board that handles this. Or they could just becomes USB-IF members at $4000 annually. Not a cheap thing in either case. Finally people who write the application programs that we use to control the K2 would now have to include the Elecraft driver so that their program could work. Chances are these "application" programmers (some are really good at it, some only so-so) might not know how to debug problems at the USB and/or kernel level. Ugh, what a mess. RS232 is a lot simpler. Let's consider developing a rig control program. With RS-232 you can take two computers and connect their com ports together. Then you could use a terminal program to see what your program is sending down to the rig. You might even quickly throw together an "emulator" for a rig that sends a response back to the program. In fact if your computer has two com ports you don't even need the second computer. However all is not black for the USB only laptop crowd! There are a number of USB->RS232 adapters available. They are inexpensive and the few that I've been lent to try out have worked just fine for rig control. They are not that expensive. I just did a quick check at http://www.outpost.com and found the cheapest at $15 ranging up to $40. Using a USB->RS232 adapter lets a USB only equipped laptop work with an RS232 protocol that probably has been well debugged. And rig control just doesn't need raw USB speeds. Anything above 4800 baud is probably more than enough for most purposes. Sorry to be long winded but I wanted to convey some idea of the ripples that would ensue from trying to oblige a "simple" request like native USB control. I have looked into doing this for a couple of project that I would like to do myself. RS232, while long in the tooth, look pretty good in comparison.

Larry AG4NN asked: What about lag bolts? --- In general that's a misnomer. They're correctly and commonly called "lag screws" because, although they have a hexagonal head to fit a wrench, they are a large wood screw. Like so many things in the English language, there are always exceptions to the rule that are often based on "common usage" by people who didn't know one from the other. In many places they are called "carriage bolts". Last time I looked, not a single Elecraft kit uses them and I suspect that interest on this forum in such things is "lagging", so I'll refer any further questions to your local hardware store.

However, USB is treated as another bus, like PCI, and drivers must be installed for each kind of hardware installed there. Since there is no way that a K2 will be of much use if it emulater a hard drvie, keyboard or mouse, Elecraft would need to provide a K2 driver for each operating system that they intend to support. Remember that Elecraft is in the Ham Radio business, not the computer hardware business. Furthermore, I have experience with these things in that I have fielded an application that simultaneously interfaces with 6 serial ports and 3 USB devices. The serial devices are much more reliable and much easier to troibleshoot. So until there is a better generic communications standard, I say that the serial port is still the best choice for a small non-computer company like Elecraft. Users only need to know which port they have attached their equipment to, and if your machine doesn't have any then you can but one that attaches to your USB port.

Not exactly DX from Ohio but I'll take it. Two thoughts come to mind: one will date me ...

What I'm trying to say is a big THANK YOU to everyone in the group who actively or passively followed along on my rather circuitous route to finishing my kit. Don, I thanked you and Gary on eham, as well. I really needed and appreciated the encouragement I received. Not to mention the incredible depth of technical saavy.

[Elecraft] Tech tip: more convenient inductance zeroing with AADE meter
I soldered a small momentary pushbutton switch directly to the small PCB that AADE supplies with their L/C meter. After selecting inductance measurement, I hold in this pushbutton, then press the meter's ZERO switch. This is more convenient than hunting for a metal-tipped tuning tool or holding a piece of wire across the terminals. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Nuts and Bolts (WAS:] KX-1 KXBD1 KEYER ISSUE)
Dave W5SV wrote: I am guessing, but my understanding is that to fasten a screw, you turn the screw; to fasten a bolt, you turn the nut (not the bolt)... at least, that is how I differentiate between the two, rather than on what kind of hear they have. With regards to fasteners (since there are other types of nuts, bolts and screws): A "nut" is the part of a fastener with the threaded hole. A "screw" is the part of the fastener with a threaded shaft. Unless it is an integral part of some larger assembly, it always has a head larger than the shaft. The shaft may be cylindrical, such as a screw that mates with a nut, or the shaft may be conical, such as a wood screw or self-tapping metal screw that does not take a nut. Obviously, a conical screw must be turned to tighten it since there is no "nut". A "bolt" is specifically a screw that is cylindrical: it always takes a nut. In the common vernacular, "bolt" is most often used to describe a large screw, (e.g. we usually refer to a "10/32 screw" but usually a "1/4-inch bolt"). Some bolts, like "stove bolts", have heads specifically designed to grip the material being fastened. They have a smoothly rounded top that is not designed to be gripped by a tool, so in that special case the nut is the part of the fastener that must be tightened. Egad! Even nuts, bolts and screws can get complicated! Ron AC7AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] KX-1 and Zero-beat Tuning Indicator?
I have one in my KX1 and it's the best accessory. I operate all the time from an external 10-cell NiMH pack, and I haven't noticed any difference whatsoever. You only see very brief flashes while tuning around. When you've got a signal zeroed in it's flashing with the signal, but if you figure conservatively that CW has a 50% duty cycle ( I think it's actually less than that) and the LED draws maybe 10ma, and you are transmitting 50% of the time in a QSO, it works out to not worth worrying about. On the other hand, the ability to zero beat the other guy priceless. 73, Mike N2HTT - Original Message - From: Scott Walker <[EMAIL PROTECTED]> Date: Sunday, June 18, 2006 1:07 pm Subject: [Elecraft] KX-1 and Zero-beat Tuning Indicator? > Just curious if anyone who has installed the K6XX SMD zero-beat > board in their KX-1 has noted or even noticed how much it reduces > the battery life?

Re: [Elecraft] KX-1 KXBD1 KEYER ISSUE
Ken, I am guessing, but my understanding is that to fasten a screw, you turn the screw; to fasten a bolt, you turn the nut (not the bolt)... at least, that is how I differentiate between the two, rather than on what kind of hear they have. Depending on where the washer is located, it may or may not be "correct"; by that I mean the body of the paddle is meant to be flat against the case of the KX1. Best regards and good luck and enjoyment with it. 73 de Dave, W5SV [EMAIL PROTECTED] wrote: Thanks to all that helped me with this issue...

[Elecraft] OT: Hakko and Icom PS wired for 220VAC
Someone I know has several items from a stay in Hong Kong wired for 220. One is a Hakko Soldering station, the other is an Icom Power Supply. I don't have the model numbers. Can they be rewired internally for 110 service? I suspect the Icom can, if it's anything like Yaesu supplies.

[Elecraft] Wayne...Eric...K2 with USB anytime soon??
Way back when, 78, I wrote the "RS-232 QTTY Interface" software for the then Exxon "QYX Intelligent Typewriter". I remember when I started that project, looking up the RS-232 Standard - at that time I recall it was an old Bell standard interface - both hardware and software functionality. And at that time in 1978, the standard had been long used and in many dusty archives then. Of course the QYX product promised to conform 100% with the then RS-232 standard. A couple months later, when we got the QYX typewriter's QTTY package working - Exxon was all happy that their product could send receive files and messages, coast to coast. Then IBM's "PC" came on the market in 81 - and the Intelligent Typewriter slowly fell out of favor. I recall, President Carter's daughter was reportedly one of our first customers, or so rumors told us. I too, here here, 2nd the suggestion for a USB interface for my K2 # 5422. Perhaps throw out the code for the RS-232, and make the space available for USB code if space need be. Fred N3CSY 73's __ Do You Yahoo!? Tired of spam? Yahoo!

[QRP-L] Trail Report
Yesterday was FUN. Of course it went different than planned. Hiked in to the FD site about 45minutes from TH. Then I spent more time slinging the weight and untangling string from brush to get the silly antenna up than operating. Started out w/88' CFZ fed w/40' RS twin lead (hung @35' inverted vee fashiion) - Actually I didn't measure it exactly but that's what I rolled off at OEM the local electronic surplus candy store - so it may have really been 90-92'. Loaded great on 20/30 w/KX1 but 9:1 on 40m according to the KX1's ATU? So I folded back the ends on themselves about ~6' and SWR droped to 3.5:1 on 40m while 20/30m still were 1.1:1 range. Could have trimmed it more but I was burning daylight! Cndx were so-so, weak sigs + slow QSB? It was getting on into the AM so 40m was getting short. I couldn't raise anyone on 40m. Headed to 30m. it was busy with CHers (I think) on to 20m where I had 3-short Qs on 20m with: n6voh/Barry in CA, nf0z /Larry in AZ and my bro-inlaw ac7ma/Rich in WA Got good reprts considering the CNDX. Goats we're getting restless butting heads etc. and got tangled in my feedline while sparing and jerted the feedline outa the ATU!. So I finished the Q with Rich on my cell. Never got to the EF setup before I ran outa time. I got home just in time to spread horse manure w/tractor and spreader for 7-hrs!!

Re: [Elecraft] Re: UK import duty
Except that, having a car isn't as required in the UK as in the US, and I don't think you have average ppl in the UK doing 20K miles a year. I myself am quite a light driver, only doing about 7k a year. And, car insurance in the US is generally $100 a month and up, not sure what it is in the UK. 73 de Alex NS6Y On Jun 18, 2006, at 1:19 AM, Nick Waterman wrote: David [M0WAM] wrote: Sorry to continue such an OT thread, but you US citizens should really count your blessings...
