Re: [Elecraft] GPD 10 MHZ Reference
Make sure the HP's output signal level is about right (~12.5 dBm, I think...) before using it. If it's a square wave output at 5V/0V, you're supposed to add a series resistor.

Re: [Elecraft] Power issue
Check the terminal voltage when the batteries start charging. If it's below 13.8V when loaded and charging is enabled, you would get the LO SPPLY message. The KXBC3 charges at a VERY low rate (around 200 mA), so it's not likely that the charging itself is loading the PS down.

Re: [Elecraft] 4-pound Field Day, anyone?
For your #2 work in progress: I've asked Grace Frisk (The NicdLady) to put together an NiMH 14.4V pack. I should have it next week. My idea was similar to Wayne's, but I wanted to operate the external pack at a higher voltage than is typical for standard cellpacks. Field Day is my target date as well. Specs - 2700 mAH, 14.4V, 39WH. Size: 2.5W x 1D x 2 H Weight: About 450g, including the 18 cable (about 1 lb total weight). In case there is any interest, I'll plug Grace's business: http://nicdlady.com/. 73, Matt Zilmer, W6NIA Semper Gumby -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Wayne Burdick Sent: Friday, April 26, 2013 9:40 AM To: Elecraft Reflector; k...@yahoogroups.com Subject: [Elecraft] 4-pound Field Day, anyone? Hi all, This year I'm going to break with tradition and *not* drag tons of gear to my field-day site. I'm going minimal4 pounds max of radio gear. This will allow me to put more emphasis on food, drink, and enjoying time with my son (now almost 9). If anyone else is up for FD4#, let me know. I'd like to compare notes on equipment, especially antennas, battery packs, and logging. 4 pounds (or so) is not an arbitrary number. This allows for: - a KX3 with internal ATU and attached paddle - mic and headphones - external Li battery, plus 8 internal AA batteries in the rig as a backup - two 50' (roughly) lengths of antenna wire, adapters, and a couple of 1-oz weights to get one wire into a tree - paper log and dupe sheets (maybe...more on this below) - soft carrying case for all of the above (in my case, a Think Tank Strobe Stuff bag) I still expect to be reasonably competitive in the 1B-battery category even with this lightweight station. I hope to operate on 80-6 meters in CW, SSB, and digital modes (RTTY using the CW paddle and the KX3's text decode function). There are two items I'm still working on: 1. External battery I need something that will fit into the bottom of the Strobe Stuff bag. It should supply at least 11 V, and I'd prefer 4 to 5 AH, though I could get by with 3 AH and switch to the internal AAs later if necessary. Has any consensus formed about specific Li battery packs in this class? Ideal max size would be 1x3x2.5 (HWD). 2. Logging I actually like paper logging in the field. It's kind of a Zen thing, checking dupe sheets manually (Griffin is old enough to help with this, too). But are there any good FD apps for the iPhone? I need the iPhone anyway so it doesn't count towards the station weight total. If there's an app that's easy to use for this, I'd love to try it. Heck, I'd even pay for it.

Re: [Elecraft] KX3 as an antenna analyser
Turning the KX3 to the purpose of antenna analyzer can be done easily using a host program on a PC or MAC. It will only be able to give you SWR, nothing more than that. See the KX3 Programmer's Manual for details. If your station is so equipped, the LP-100A can be used as a vector antenna analyzer and can plot Smith charts, R+jX, etc. This is also run from a PC or MAC, and the results are logged on the computer. This approach would work with any transceiver supported by Larry's LP-Plot program. See www.telepostinc.com for details. It's possible that there is a host program for the W2 (Elecraft) wattmeter as well, but I'm not aware of it. I'm pretty certain the W2 isn't a vector wattmeter like the LP-100 and LP-100A.

Re: [Elecraft] Watch the ions
Interesting aside... I worked for an In-Flight Entertainment development firm, and our premier product line was a series of Ku-band sat receivers for EchoStar (Dish). The EchoStar footprint drops off severely at US borders. Dish had a similar restriction to the one that Ron found re PBS. In addition to the signal level problem at the borders, the sats' antennas hotspot metro areas, so that smaller dishes may be used in population centers. In the middle of flyover country, a bit more of a ground station antenna is needed to maintain link margin. Link margin and antenna budget being what they are in that business, we developed a steerable airborne antenna based on an array of Luneberg Lenses and it worked well. At least it worked well away from borders and in metro areas... Unfortunately, the System Engineer that developed the antenna specs lived in a city, and far from borders. The EchoStar spec said nothing about the contour of the signal, and how it varied. Link margin as-designed was 1.5 dB (a reasonable margin, so I'm told). So far so good. US air carriers sometimes stray into Canadian airspace, and this depends on the flight plan. US carriers also fly right over the center of the country. We designed with an affordable ink margin, but not enough to cover the contour dips at borders and in flyover country. We got into big trouble with the airlines because of LOS occurring in these two circumstances. This involved a lot of penalty money changing hands, and a lot of free flights for our engineering staff to try to work out the problems (which is when we figured out the variable link margin problem). The amount of trouble we got into when Dish found out about airline passengers viewing US-licensed live content in Canadian airspace cause the earlier problem to fade to complete obscurity however. Live and learn.

The old adage When it rains, it pours! certainly fit this one. It started about 8:00 yesterday morning and dumped around 5 inches in the first round, another inch in the second and then overnight it dumped another 6 inches of snow. I think there was some rain in the second round as well so not absolutely sure the total. The rainfall equivalent was just about 1.4 inches. How does this relate to ham radio? I have a heart pacemaker so not allowed to shovel all that snow and my wife went out last night to start on it. Our neighbors came over and shoveled the walk for us. Driveway cleared about 7 p.m. and after a nice bit of thanks and conversation, everyone went in. Still not related to ham radio? This morning we woke up about 4:30 to the sound of thunder! Yes, thundersnow! When we finally got up around 7:30, you couldn't tell the driveway had even been cleared last night. Now, comes the good part - wifey went out again and started to clear the driveway again. This time, another set of neighbors, two houses down that had just moved in a month or so ago were out doing their own driveway. They made a deal with my wife that if she would watch their two year old daughter for a while, they'd shovel our drive too. She agreed and I was on 40 CW when they brought the little girl over. She was fascinated listening to the CW and spent the whole time here in the shack with me intently listening to the CW activity. She didn't even want to watch cartoons on TV. Her dad said that was the first time she ever settled down immediately at someone else's house and wasn't fussy at all. Especially this early in the morning. Might have started a new ham career, who knows? Anyway, this might be the first case of a K3 babysitting a two year old and coming out unscathed - she never tried to grab the radio knobs, key or anything, just sat there and smiled the whole time. My only regret is that I didn't have my wife take pictures of the whole episode. Might have to get the neighbors to bring her over again and see what happens.

Re: [Elecraft] K3XREF Question
Hi Bob, I use the Trimble Thunderbolt as a 10 MHz reference. This is a GPS disciplined clock, using GPS as the main time reference and an OCXO. The time and 10 MHz output are both very precise, in the 30 PPT range (though this precision varies, but not by even an order of magnitude). You can find the manual at http://trl.trimble.com/docushare/dsweb/Get/Document-10001/ThunderBoltBook2003.pdf. You will need to mount an outdoor GPS antenna. I use a Thales land surveying antenna and 40 feet of microwave coax. The receiver generally sees 8 channels with more than 40 dB C/No (which is a good signal for GPS). There are two software apps you may want to pick up: - Trimble's control program. This is used to set up parameters for the receiver. - Lady Heather's GPS Disciplined Oscillator program. This can be used to monitor the status of the receiver and signal levels, time, etc. graphically. One thing you would want to set up different from the receiver's defaults is the elevation mask. I believe the default is 5 degrees. I'd recommend 15 degrees. This tells the receiver not to use sats below the 15 deg horizon. The lower in the sky a sat is, the noisier it is.

Re: [Elecraft] [KX3] and RMS Express, Winlink.
Hey Gil, For WL2K and all data modes, just use Line In and Out to your sound device. You can key the KX3 via the serial port, using DTR or RTS via the USB-Serial adapter. Doing this requires a current-limiting resistor in series on the control line (DTR in my case). I'm using 3.3K for mine, and it keys PTT just fine. RMS Express allows a transceiver choice of Elecraft Radios in the Radio Setup. I've got that choice selected, running in Digital mode (Digital USB). There are two serial ports shown, one for control and the other for PTT. I have two virtual ports (COM19, 20) running through LP Bridge, connected to COM3. COM20 is used to key the KX3, and COM19 is used to control the radio (frequency, mainly). Elecraft sells a cable set specifically for this type of use (KX3-PCKT). The quality is better than average and the cost is only $20. 73, Matt Zilmer, W6NIA / NNN0UET SCA -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Gil G.

Re: [Elecraft] KX3 Smarter Charger
Good statement, Chip. Right on the mark. For quite a while now (since inception?), Elecraft's design philosophy has been to make their products bulletproof. That's not the same as being perfect, but there is also heavy emphasis on best value per dollar spent. This is a close approximation to perfection for value markets. At the same time, even in higher end markets, Elecraft products are feature-wise highly competitive. The 200 mA charge rate is a good example of bulletproofness. At this rate, there is very little that can go wrong, even if one or more cells is defective or even just beyond its service lifetime, or if the op overcharges the cells. Since Elecraft can't control the characteristics or histories of the cells an op puts in his/her KX3, this approach is probably the best compromise in pure design terms. Sure, there will be some users that see a 12 or 16 hour full charge cycle as being unacceptable. But at the same time, their charging solution just works, keeps support and warranty (and customer dissatisfaction) issues at bay, and meets the requirements (charging the batteries). As Chip said, the electronics is packed pretty tightly in a KX3. You wouldn't want an inadvertent defective cell [at $5 to $10] to damage $1500 worth of radio, especially by heating or fire. In consumer electronics (where I work), our products have charging requirements that are remarkably similar to Elecraft's with the KX3. Certainly we have mishaps, and some of them can be pretty spectacular in fact, but these are all due to manufacturing defects, not a defective design. Just my $0.02 worth.

This occurs most reliably at fairly high charge currents. With 8 cells in series, that voltage drop can easily be masked by what is happening in other cells, such that while some cells are still charging, others may be getting seriously overcharged to their detriment. This type of charging also requires a constant current charge to allow detection of voltage depression. Constant current supplies use switching regulators - so more noise in the shack. Additionally, as Nimh cells age, that voltage depression becomes less pronounced. I've had even good quality smart chargers miss end of charge even when only a single cell is involved. Then you have to keep in mind that these cells are very close to some expensive high density electronics. I think rupture or outgassing of Nimh cells is rare, but I wouldn't want to chance it.

Charging at lower supply voltages would have required a switching boost regulator which then gets into problems of space, RFI, and cost. It is possible to put some charge into a depleted set of batteries from a lower supply voltage but they just won't be able to get fully charged. Because the battery holders will hold any kind of AA cell, we opted for safety and charge reliability when it came to selection of how the charger operates. With 8 NiMH cells in series, the influence of things like temperature, cell condition, and other factors make automatic detection of full charge at moderate charging currents unreliable. A timed charge may not be elegant, but it's the approach recommended by the major battery manufacturers when not doing a fast, smart charge. And the latter requires much higher current and was just not feasible in the KX3 due to safety, power requirements, heat, RFI, and a few other things. Hopefully this helps explain a bit why the charger operates as it does. 73, Rich AC7MA On 01/30/2013 10:33 AM, Alan Davenport wrote: Your questions are valid. I asked the same ones myself.

[Elecraft] K3 ESSB question - data modes
In MARS, we use a mil data mode called M110A which requires 3 KHz of TX and RX audio bandwidth to achieve a low error rate at the higher bitrates (2400 and 4800). I've been trying it using DATA A, but error rates on the RX side (for non-K3 RXs) is still higher than acceptable. I'm assuming that the K3's TX and RX audio characteristics would be the same when using 3.0 KHz in ESSB. Since we have at least two Navy-Marine Corps MARS members in SCA with K3s, I was going to test RX error rate with each RX set up on ESSB 3.0, while my K3 was set up the same way for TX. Another way to assess usability is to run the N-GEN into the K3 RX while in ESSB 3.0. The output audio spectrum should show a clean audio band. Has anyone in this group done this already? If so, could I get a copy of the results? 73 and Thanks, Matt Zilmer, W6NIA/NNN0UET SCA __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3 or KX3 on my sailing yacht?
This is true. There is a smallish guard band around the US CB 27 MHz frequency range; no TX inside of that range. It's something like 26.8 MHz to 27.5 where no TX is ever permitted. Elecraft's standard unlock utility program unlocks TX outside the Amateur bands from 2 to 25 MHz. The region from 7.5 to 9.0 is always protected, being too near the 8.215 MHz IF to be usable. There is a utility that may be provided separately that unlocks the range below 10m that is not included in the lockout for CB. So MARS and CAP frequencies between 25 and the lower end of the CB guard band, plus frequencies from the top of the guard band up may be used for TX. There are a number of MARS frequencies at or around 27 MHz, mostly allocated for phone patch and relay activities. Matt Zilmer Consultant - Product Management Dept.

Re: [Elecraft] Wall wart for KX3
George has an excellent point (killing good radios), but be advised that the KX3 is designed to work from pure DC power (batteries) and doesn't tolerate power supply ripple and transients well. So filtering of the DC is necessary as well as good regulation. Most wall warts out of the box have neither. This comes true in spades, in a mobile installation (see http://www.elecraft.com/manual/Rev-B1-1.6-KX3-Mobile-Owners.pdf for more on mobile installations and ops). My on the road AC supply is a MeanWell switcher. It's got a few broad HF spurs. I treated these as conducted emissions and used a Laird LFB174095 ferrite core w/ 5 turns through it to suppress them. There are still a few spurs being radiated, and even though they're broad they are also below the atmospheric noise level. KX #6 only hears them with the antenna cable disconnected.

It turned out to be a fault with the sound card, which took out the serial connections. When I first built the K3, I bought a cheap Prolific USB converter, which radiates awful noise over the spectrum. I decided to bite the bullet and buy the proper lead, which arrived today. Using my Toshiba laptop, on battery power, I get a couple of s points of noise on 10M with the KUSB connected and HRD fired up. This is using my 2 element DJ4VM quad, which is fed with 300 ohm twin into the shack, i.e. near the laptop. On LF, I can hear the pulsing information, in sympathy with the flashing LEDs on the KUSB on 160M at quite a high level. I can even detect this when fed into a Marconi dummy load. The K3 and the tuning units are bonder to an RF earth - a copper stake about 8 feet away from the K3. I have tried choking the USB lead at the laptop end, which does reduce the noise to a degree. The question I have is - am I being unrealistic in expecting zero noise to be radiated from these adaptors? Does anyone else have this problem - or has anyone looked for it? It is not very noticeable on CW or SSB. To hear it best, listen in the AM mode with the AGC off. On SSB it sounds like band noise. Is this a problem JUST with USB adaptors or can I expect silence when connecting a computer via RS232 to RS232. If not we are sacrificing a low noise floor for the convenience of computer control.

Re: [Elecraft] Big weakness in Macro's
A while back, I wrote a CW functional test for the K3. In doing this, I ran straight into the programming problems cited earlier by Ed. My solution wasn't very innovative or elegant (not being involved in the firmware development at all), but it was adequate and met the requirements. After establishing comm and getting control of the K3, the I would poll the toggle and multi-value states parameters that could be set by the program. There was a list of 25 or so controls of this type, and I would just add new ones as needed. The really fun part was reading back the values. I had to dump the VFO A or VFO B displays to do it. I took my cue from Dick Dievendorf, assuming he'd done something like this to read back the RTC time in the Set Date and Time tab on the K3 Utility. Having the MN and MP commands saved a lot of effort as above, but the implementation is partial. That is not all MN parameters can be polled or set. So displaying parameters' toggle or multi-value state is about the only way, in the general case. For a multi-value parameter (TEXT DEC is one I had to use a lot!), dialing through all the values is a little cumbersome and requires as many functions to get/set as the number of parameters that are used. OTOH, there are probably many MN parameters that would never be used by a hosted program and I believe that's why Wayne decided to implement the ones that were obviously needed or perhaps only those that were requested by software developers. At the start of the program, I'd store all the toggles and multi-value parameters that the program could touch. When exiting back to Windows, the app would restore these, including the initial baud rate. The idea was to leave the K3 in the same exact state before and after. I would guess the best argument for having a known default state is from Ed. But executing such a command would introduce a bit of entropy, meaning the K3 would end up in a different state from what it was when the hosted program was started. This might be ... disturbing ... to users, and disruptive to using the K3 without having to manually restore a bunch of parameters' states. 73, Matt Zilmer Consultant - Product Management Dept.

One big rule in programming is you always set the state of things so you are always dealing with a known starting point. The command structure in the K3 does not permit this. A number of things in the K3 are toggle, for example in MIC SEL 1 toggles the mic back and forth from high to low and 2 toggles for bias on or no bias. There are a number of other instances of this in the K3.

I have a Deka 95AH AGM battery that is on continuous charge via a homebrew 25A smart charger.

The charger uses a modified Astron 35A supply to provide the raw DC and pass transistors. A slightly modified AA Engineering card delivers the smarts. Contrary to what some in this forum will tell you, this combination will not overcharge the battery, but will keep it fully charged even while transmitting at 100W, even during an RTTY contest.

I wouldn't be happy with an acid spill there. So I'm looking for battery size and type information and what sort of operating time I might expect with QRP and 100W levels (and anything in between...). Also would like some recommendations for practical handling and charging to avoid issues. Charging would be from the AC line. No solar planned. I'm pretty sure an AGM deep cycle battery is what I've seen recommended. What else should I look for?

Hi Chris, I've done a lot of mobile ops with my KX3 (almost every workday). I got the basic mobile installation completed in March, and finished up more recently (last weekend). Mobile with Elecraft is *a lot* of fun, and I've just gotten back into mobile CW using mobile QRP. The antenna system is Hustler, so have to move resonators from time to time - but it does work and I found that while mobile there are fewer compromises than I expected. When I'm stationary, I lay out a couple of radials clipped to a shipping hook. At Elecraft's request, I documented the mobile installation plus safety, legal, power, and cabling considerations in a KX3 Mobile User Guide. It's posted at http://www.elecraft.com/K2_Manual_Download_Page.htm#KX3. It's the 7th line item from the top of that tagged page.

Re: [Elecraft] K3 Plasma Question
Plasma TVs should be made explicitly illegal, because of the interference issues they cause on HF. But the reverse is also often true. I had a neighbor who bought a plasma TV. The dern thing put out all sorts of QRM and gudge around 4 MHz (near one of the MARS frequencies). As I operated more and more often on that MARS freq, I found that the interference decreased over time (at least when I was on the air and transmitting). Much later, the neighbor reported that she'd taken the TV back to the retailer because right around 5 PM every day she couldn't receive anything for a few seconds at a time. She assumed it was defective (it was) and they gave her credit for another (LED) TV. We live in an area with large setbacks, so her plasma set was more than 100 feet from the antenna. She's had no problems with the LED TV.

We have two plasma TV's in our home. One is a ten year old Sony 42 inch unit. The other one is a two year old Samsung 63 inch TV. They are about 50 feet from the shack, and only eight feet away from each other - two different rooms. The Sony has never, ever caused any sort of QRN on any of the ham bands. Because of that, we purchased the Samsung unit right after moving into this QTH. I did not have an HF antenna installed for several months after moving in - when I finally did get one put up, I saw some ugly QRN on most of the HF bands. However, at the time I was not aware of the plasma effect that I am now. When I heard the QRN, I assumed it to be from the PGE high power lines that are pretty close to the house. By the time I put two two together and figured out that the ugly noise was from this Samsung TV, it was already out of warranty. Ughhh We are now in the market for another TV, and have been looking at a very nice Panasonic 65 Plasma set, model TC-P65VT50. I've already told the Best Buy sales manager that IF we do buy it and IF it causes QRN to the HF bands, it is coming right back. He said that is no problem. But, if I can query this group to see if anyone else has one of these TV's, I may be able to avert a lot of work ahead of time. Our second choice would be an LED set, but after seeing plasma and LED side by side, playing the exact same content, I want to stay with plasma - BUT ONLY IF IT DOESNT SCREW UP THE K3!!! __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

As soon as trying some functions, I found it's really a direct conversion system. A weak leaked signal was observed with another receiver just on the watching frequency. In my boyhood, I built Mizuho DC-701 which was a copy model of Heathkit HW-7. DC-701 also adopted direct conversion system and my local station could detect my receiving point. The leaked signal from KX3 is not so strong as that of DC-701 and almost no problem. Direct conversion with DSP system will be possibly adopted in higher class transceiver. DC on 2m is interesting, however, challenging. So transverter is reasonable solution and I'm expecting the module again. Many thanks for proposing the innovated equipment. The block diagram shows the transmission system is also 'direct conversion'. The local oscillating frequency seems to be basically equal to the transmission frequency. Is it correct? Just one more twitting. The optional microphone looks something a little cheap, because it's same as that of Chinese kit KN7Qa.

In a simple implementation of dual watch, the first demodulator would sit on centre frequency, and the second would shift +/- 15kHz from that. In a trickier implementation, VFO would be shifted up or down 8kHz or even more, and VFOB would then be able to range a bit further, and give a bit more than the current +/-15kHz separation). As for whether the RX SHFT affects the centre frequency of the RX I/Q outputs, I'm not sure.

Elecraft sent a replacement HPA that did not correct the problem. The replacment HPA had two capacitors hanging off the side. Returned the K3 to Elecraft and they found a drive transistor in the LPA was defective. 3. Loss of sensitivity at turn on. Took about twenty minutes to reach full sensitivity. After many weeks of back and forth discussions, Elecraft sent a relay which I installed. It did not help. Sent the K3 back to Elecraft. They found a defective solder joint on the RF board. They installed several updates. Elecraft extended the warranty to 18 months. 4. CONFIG menu was scrambled. The adjustable items did not line up with the item it was to adjust. Wayne at Elecraft got involved after several exchanges with support. Finally resolved by doing a complete reset and installing all new software. Had to recalibrate all functions and reset all adjustables in the menu as the back up was also corrupted. 5. Power adjustment was erratic. Sometimes it took five or more complete turns to change power from about 30 to 100 watts. Other adjustments controlled by that encoder seemed to work okay. Again, it took weeks back and forth with support. They finally shipped a new encoder which I installed and that corrected the problem. 6. ATU would not tune. No relay action at all. The ATU was not in bypass. After instruction from support to recalibrate several functions and perform other tests, it begun to function properly. I'm wondering if this K3 has had the gold pin modification. Got near simultaneous responses from three different individuals in support when I emailed about the problem. Some troubleshooting overlapped but the varying directions from three different technicians was confusing. Do they have a triage system with one technician assigned to work a problem? 7. Concentrite knobs near the microphone connector cracked. I took the K3 to Field Day and when I removed it from it's Pelican like case after returning, the knobs were cracked. Support sent replacements. The replacements are a matt black and the other knobs are glossy black. The replacements color and finish look weird compared to the originals that remain on the radio. I and elecraft have been unable to determine if the frequency response modification has been done. The radio was shipped at about the time the modification was begun. It appears to have different capacitors from earlier PCB's but there was no daughter board installed. I installed a daughter board myself. I also have a K2 and several mini-kits. The k2 has had no major failures. But I've calibrated the dial and set the filters several times. At the Dayton Hamvention in 2011 I attempted to discuss the radio with Eric. His response was to call support and he turned away. I realize it was at opening time but a can you get back with me after we get open would have been received much better. I

But, once the macros are assigned from the present 8 K3 memories to

not be written over for the next batch of 8 different macros to be
assigned as multiple macros to other 1-8 or PF keys.
There's the rub ... if you load new values to Macro 1 - Macro 8 your
multi-state macro *will no longer work correctly*. The multi-state macros work
by *assigning new values* to the key every time you press it. If you change the
contents of Macro 1 - Macro 8 the new value of Macro 'n' will be assigned to
the key - not what is expected by the multi-state macro.

Given the usability of these multi state macros it would be valuable
if Wayne would extend the number of macro slots that can be assigned
to K3 switches. In effect each of these toggle or tri-state
macros is two or three individual macros that remap the key on each
step - with at least 10 assignable keys (M1-M4 tap, M1-M4 hold, PF1,
PF2) if each key were used for a multi-state application the number of
required macro slots could easily exceed 20 if each key were used for a
toggle function.
If one does not use DVK/CW/FSK memories, the number of available keys
(10) already exceeds the number of assignable macro slots (8).

I've been doing this with 2 macros to switch the L-MIX-R menu item,

following 2 macros both allocated to
M4 TAP does just that and now releases the M4 HOLD for another macro.

Thanks to whoever thought of all this, it's pretty neat. The first 2
fields
(MN111;MP003;etc) switch the L-MIX-R and were originally allocated to
tap and hold separately; the other fields reset the macro as in the
'Triple Macro' examples.
As an aside, it would be great to be able to comment the macros (in
K3

found this is possible. Presumably this won't work unless the

Re: [Elecraft] KX3 interal battery charger
There are other ways to achieve charge parity (balance). One of them is the multi-cell charge controller. An example for LiPo chemistries is the AAT 3663. Datasheet is available at www.analogictech.com. Doesn't help with AA's, but there is probably an equivalent out there for lower voltage single cells. Looks to me like Greg is correct about the difference between balancing and equalizing. Xantrex / Trace refers only to equalizing with their controlled overcharge on solar charge controllers. EQ is used with FLAs to stir the pot and disturb sulfation on the Pb plates, and the process basically allows the sulfates to debond from the lead. With FLAs, I run an EQ for two hours about five times a year.

The idea is to be sure that each cell is properly and fully charged without overcharging or damaging any of the other cells in the pack. This is quite common with the all the various lithium chemistries, and when using NiCd or NiMh smart chargers that charge each cell independently. Most of the inexpensive consumer NiCd and/or NiMh chargers do not treat each cell independently. Only the more expensive models include the test/refresh modes. Although NiCd and NiMh cells are often overcharged by many slow chargers, apparently that is not the best practice when performed on a regular basis. Thus, the smart chargers. If I am understanding correctly, a PbAcid (e.g. SLA) equalize charge operation does not have access to each cell and instead is an operation that uses a carefully controlled overcharge function, within the safe operating envelope of the battery, to bring up the lagging cells without damaging the stronger cells. It sounds like equalize and balance are two different operations, intended for different cell chemistry and charging styles. Starting with a fresh set of Eneloop (white label 1,900 mAh or black XX label 2,500 mAh) or other brand of pre-charged or low self-discharge (LSD) NiMh batteries that have had at least one test/refresh cycle performed, the need for removing the batteries from the KX3 for a test/refresh cycle should be VERY infrequent as long as they are not abused significantly. As Jim mentioned, hopefully this won't be too often. Who knows, even with heavy use, maybe the batteries won't need to be removed for over a year - or two. Yes, Greg, I plan to do things exactly as you stated: check after a few months, but then pretty much leave them alone in the radio for a long while as I see how things work out. I will be interested to hear from folks here on the reflector as experience is gained. With the traditional non-LSD high capacity NiMh batteries, the need for test/refresh may be a bit more frequent. For example, the Energizer 2600 mAh (?) AA cells are notorious for extremely rapid self-discharge and may need a bit more care and feeding. 72/73 de JP WF4Z On Wed, Jul 4, 2012 at 3:25 PM, Greg Troxel g...@work.lexort.com wrote: In balance vs equalize, I also hear about equalization charge to 12V SLA batteries without access to individual cells. PbAcid cells have a higher charge/discharge marginal ratio as they get full, so a mild overcharge should tend to cause all cells to be fully charged. NiMH is almost certainly similar, especially during low-rate overcharge as is typical, so I'd expect that all cells end up full. To understand the KXBC3 behavior, it seems that one should use a Maha C9000 or equivalent to measure/record the capacity (refresh/analyze) of all the cells, and then put then in the KX3 and use them for a while, and then when the KX3 says they are charged pull them and do a discharge measurement followed by a refresh/analyze.

Re: [Elecraft] 4.48 vs 4.51 CW Decode
Contests aren't the best setting for CW decode, imho. However, if you tune the CW slightly higher than the CWT indicates it seems to improve decoding when there is band noise present. If you minimize the passband to 50 or 100 Hz, this also helps reduce noise in the decode channel. With the passband minimized, the decoder gets good results with the CW and CWT matching.

Re: [Elecraft] Field Day experience with K3
You might want to get a battery booster. Here is one http://stores.tgelectronics.org/Detail.bok?no=10. I can recommend that one. Had one for a couple years and use it to boost to 14.5VDC from whatever voltage any time of day from a solar-charged battery. I think my K3 likes that 14.5V!

The K3 is less robust to supply voltage than the other Elecraft radios. The K2 is rated for 10-15 volts; the K1, KX1, and KX3 go down a lot lower, I think 8 volts. I looked at the K3 documents to see what minimum voltage it requires, and I couldn't find it -- I think it's something like 11, but it may be 11.5 or even 12. You'd probably do fine just by using a separate battery for each radio, and not letting it run down too far. A voltage booster isn't needed, as lots of operators all over the world have demonstrated.

Re: [Elecraft] K rig's longevity?
Since I hardly ever post here, I have no guilt over doing so on this moderately controversial topic. Many software houses and embedded systems outfits make their software components available, only in the event of their demise, via escrow. Typically the escrowed software follows the comapny's assets as it is bought and sold. But it also may be released into the public domain or to a specific customer if the company's assets exceed its liabilities and no entity rescues it. Going out of business is the term I was looking for Escrow into the public domain is not typical, because most companies that fold still have residual assets, and usually someone buys them at fire sale prices. Many valuable [not market value, but value to each/any of the users] assets like this are locked up in IP Farms, where IP = intellectual property. That's usually not good for a large user base, but it's reality. I believe the escrow writer can specify that the asset(s) may be disposed of in a certain way, and that this spec follows the asset(s) forever. But I've also heard of IP houses getting around this and locking the door forever. We used escrow and trade secret modes at a very interesting little crypto house I worked at a few years ago. Some of the agencies we did work for insisted on certain terms and conditions, and that the design disclosure include all data/specs on all components needed to reproduce the design in its entirety. All of the stuff that wasn't deliverable in the contract was held in escrow. Escrow may be a possibility for Elecraft, but they'd have to look into it. I have a feeling they're staying a little too busy to take the time. matt zilmer, WA6EGJ K2, s/n 2810 Upland, CA. == On Sun, 30 Sep 2007 23:16:04 +0100, you wrote: [EMAIL PROTECTED] wrote: Will it be possible to keep a K2 working 35 years? I don't see why not, given that almost all the parts are readily available, the documentation is wide open and free, and expert assist is available from several sources. Plus when Most of the documentation is closed, as, as you point out yourself, the radio does a lot in software, and the software source isn't released; not even the AuxBus protocol is documented. It's also the case that component substitution, including piggy backed surface mount parts, have had to be made already. The impact of the closed software is that, even if you can get the PIC chips, you won't be able to program them. Also, where the firmware has restrictions for legal reasons, and these go away (e.g. the Thai government permits use of additional amateur radio frequencies, or, on my reading of the UK licence, and assuming the situation has arisen and Elecraft have actually complied, if a UK Novice gets a Full licence and is therefore allowed to operate equipment that is not restricted, by design, to authorised frequencies, the user may have trouble getting an upgrade). Incidentally, making the software public domain is not a good idea, as it will be ineffective in the UK, and most other countries, with the, probable, exception of the USAb, and doesn't allow one to restrict implied warranties. It's better to use a liberal and perpetual licence. The other issue is that Elecraft is a small company and we have discovered, this week, that one of their founders is turning 50 and another key technician learned algebra in the late 1950s, it seems to me that a lot of the key personnel are reaching the point where they think about retirement. As well as losing the product knowledge, founders of startup companies in that position often want to turn the value of the company into cash to fund their pensions. To me, the K3 could well be there in order to make the company sellable. My experience of innovative startups, where the founders sell out, is poor. I've had to leave my old ISP, because of the consequences of that. From what I know of the hardware, I would be most worried about the K2 headphone jack, as it is not particularly generic and a known weak point. I'm also somewhat concerned about the relays. They are almost impossible for an individual to source and they have a limited life, and the KAT2, in particular, hits them hard. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

They come with a 4 pin mic connector that you must change to 8 pins, but you can wire the new mic plug for any mic configuration that you want - I suggest the Elecraft wiring - straight across (use computer jumpers) on the mic header. 73, Don W3FPR Greg Derda wrote: Hi all, I am in the process of building K2 #6100 and need to start thinking about a microphone. I've looked over the Reflector archives, and it seems that there are lot of little mods needed for a variety of microphones. The simplest solution would be a MH2, but I don't know that I can wait until the June 15 production date. Question is, can I not just jumper my K2 for Kenwood, buy a Heil HM-10 or Handi_Mic, and plug-n-play (without any internal K2 mods)? I will get a Pro Set someday, but I just want a decent little microphone to get me started. Any suggestions?
