Re: [Elecraft] KX3 Approx Cost/User Downloads/Dev
I'd love it if you could make it work with VoiceOver, the built-in IOS screen reader. I've been looking for a way to remote the K3 and just started learning the IOS. Many apps work great with VoiceOver so why not a K3 or KX3 controller? Thanks.

Re: [Elecraft] unequal tone power output in FSK
I agree with Dave. If what you were seeing was due to passband ripple, choosing a different RTTY pitch should make a difference. I don't believe it does. Not only that, but if it were passband ripple, it would affect AFSK A the same as FSK D. My solution to this is to use AFSK A - it has almost all the same features as FSK D, but produces cleaner output. 73, Rich VE3KI Dave K6LL wrote: Are you sure you are seeing unequal steady-state power on mark and space?

[Elecraft] K3 Auto antenna switching
Thanks, Fred. I switched DIGOUT1 on while on 6m and it remembers to be on, only on 6m. My application will be to control an external relay that will enable INHIBIT for 6m-eme. As already mentioned, I use BAND0 for this on 2m and higher transverter bands, but I do not want INHIBIT for normal 6m use, only to sequence my TR relay and Harris 900w 6m PA, when using it. Applying RF drive without a load on the Harris can destroy the amp. One does not want to hot-switch the coax relay as 900w courses thru it! So you can add another use for DIGOUT!

Re: [Elecraft] KAT2 with EFHW antenna
Yup ... I was wrong again, but the trouble is I can't figure out why. I mean, it's easy to verify the cloverleaf pattern with EZNEC and I have done so, but I know that I have modeled something similar with an off-center feed in the past and gotten an end-fire pattern. As soon as I figure out what that was I'll come back here and try to clear up the confusion I have caused, but in the meantime let's all just agree that I don't know what I'm talking about. sigh ... 73, Dave AB7E On 8/25/2011 11:13 AM, Guy Olinger K2AV wrote: Sorry to interject, but a fullwave fed at the 25% point has a clover leaf pattern.

Wayne, Thanks for the link. Perusing the details, I note a single antenna connector, which makes sense with a compact radio. But I do not see evidence of a transverter interface. I was not sure if that was being included - appears not. Being QRP, this is not hard to overcome by use of a 10w 40-dB attenuator chip and pin-diode relay in the transverter to switch TR at the transverter. Many transverters can be ordered with a transceiver connection option. The KX3 with 2m option should look very attractive as an alternative to the FT-817 as IF radio for VHF and Microwave hams.

The transverter module, if installed, will have its own antenna jack. It will be an SMA connector due to space constraints on the right side panel.

I've gotten to the point, that before I say anything about a model, I actually run it and play with it, to make sure I haven't forgotten something, or remembered something wrong. As to that particular antenna a center fed half wave antenna is troublesome. The better version of that if one wants that pattern is the extended double zepp, two 5/8 waves fed in phase, where you are feeding a lower impedance at the center, and it's a far less cranky antenna. The double zepp maintains its essential shape fed at 45% whereas the halfwave converts to cloverleaf. That's ancient knowledge, garnered by experience in the 40's and 50's without the benefit of software. These days if you can't look it up for free on the internet, it's forgotten. 73, Guy.

I mean, it's easy to verify the cloverleaf pattern with EZNEC and I have done so, but I know that I have modeled something similar with an off-center feed in the past and gotten an end-fire pattern. As soon as I figure out what that was I'll come back here and try to clear up the confusion I have caused, but in the meantime let's all just agree that I don't know what I'm talking about. sigh ... 73, Dave AB7E On 8/25/2011 11:13 AM, Guy Olinger K2AV wrote: Sorry to interject, but a fullwave fed at the 25% point has a clover leaf pattern.

For some reason I was thinking about a full wave antenna fed at the 25% point (I have built such antennas before), which looks like two colinear half waves fed out of phase. The current phasing along the antenna would indeed be much different and give a cloverleaf pattern if it were end fed. I wholeheartedly apologize for any confusion I may have created. 73 and thanks for catching my mistake. Dave AB7E On 8/24/2011 3:23 PM, Don Wilhelm wrote: Actually Dave, a full wavelength wire will have a 4 leaf clover pattern - that is neither broadside to the antenna, nor off the ends. Check out the pattern for a 1 wavelength long wire in the ARRL Antenna Book. The maximum radiation is about 28 degrees from the wire - the radiation from the end is almost zero. The elevation angle of maximum radiation is similar to a half wave dipole - about 15 degrees with a lesser lobe at 45 degrees (that is for a wire 70 feet high, at lower heights, the angle will be greater). 73, Don W3FPR On 8/24/2011 5:34 PM, David Gilbert wrote: I'm not sure I see the advantage. A full wave end fed antenna would theoretically have the same very high feedpoint impedance, and would additionally blow most of it's radiated energy at a fairly high angle off the ends of the antenna instead of broadside at a lower angle. If you find it that easy to tune, I suspect that electrically it really isn't that close to a full wavelength ... possibly because of coupling to earth (if it is low) or nearby structures. Either that or there is a lot of loss in the system somewhere. 73, Dave AB7E __ 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
Re: [Elecraft] KX3 Batttery life question..
Field testing hasn't officially started yet, other than testing of the four units in use by the design team. But I can give you some estimates. Receive-mode current drain will typically be 130-170 mA depending on supply voltage, backlight level, whether the preamp is on, etc. So a 2500 milliamp-hour internal 8-AA battery pack would provide an average of about 16 hours of continuous use. This is 2 to 3 times what you'd get with other small all-band/all-mode radios that consume ~350-450 mA in receive mode. Transmit current varies with power level, band, supply voltage and other factors, but in general it's about 1 amp at 5 watts and 2 amps at 10 watts. At 10 W, you could probably run for 10-20 hours from a 12V 7AH battery, assuming typical hunt-and-pounce or casual operation. Transceive operating time from an internal battery will be determined by voltage or energy-density limitations of the 8 AA cells being used. You'd probably be transmitting something like 10% of the time (good QRP practice). Assuming a 2500 mA-hr pack, 1 A current drain in TX mode, and 150 mA RX, you might get as many as 10 hours of casual operation. 73, Wayne N6KR On Aug 26, 2011, at 10:13 AM, Dave KK7SS wrote: Is there any feedback from the Beta Tester(s) regarding battery life under operational conditions?

[Elecraft] SMH command behavior
I realize this is still a somewhat experimental command. I just loaded FW 4.39 to play with the SMH command and integrate it into Hamlib. Playing with the command in the K3 utility I find that when SMH is sent a previous meter value is returned and then upon a second sending of the command the current value is returned. For example, powering on the K3 with my S-meter showing S6, I send SMH; and receive SMH000; from the K3. A second SMH; returns SMH030; as would be expected. Setting the RF Gain to show S9 results in SMH029; and the next SMH; results in SMH042; as expected per the release notes. Cranking the RF Gain to full S-meter scale once again reults in 0042 the first time and 104 the second. Going the other way and opening the RF Gain so the meter shows S0 the first query results in 104 and the second 004. Is this caching intentional? I would expect the command to return the S-meter reading at the moment it was received by the K3. As some software may have several tenths of seconds between queries of the S-meter, this would result in the software receiving erroneous or much delayed information. I find no such delay with the SM command. 73, de Nate N0NB -- The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true.

Re: [Elecraft] SMH command behavior
Hi Nate, This is a side-effect of the current SMH command implementation. Removing the side effect is on my list. But SMH is functioning well with S-meter Lite, the original target application.

Re: [Elecraft] P3 - to be or not to be - that is the question
The P3 does -not- need to be powered off to perform K3 firmware updates. I believe early versions of firmware required this, but this has not been the case for a long time. The P3 can remain on and in line. Use the P3 Utility to update the P3, and the K3 utility (set to the same port) to update the K3. Just remember to only run one of the utilities at a time. Simple. -Bruce, N1RX Congrats on the new job!

Yes. It works FB to update the K3 through the P3.

If you do manage to run a hammer or other object through the display ruin it, it is easily replaced. It is not soldered onto a pc board; it's a simple plug-in affair.

Re: [Elecraft] KX3 Batttery life question..
Hi Wayne, please don't sacrifice performance.

Re: [Elecraft] iPad/iPhone control app
I received a couple of emails asking how the app would connect to the radio.. There are several options. WiFi/Serial and Ethernet/Serial adapters are available that could provide the serial communication with the rig. Why don't use Bluetooth? I developed a small BT module that connects directly to the RS-232 port of the K3 (and is available as a low cost kit from the German FUNKAMATEUR magazine). Works like a charm controlling the K3's serial interface, I use it all the time for rig control during contests, etc. It could also be done with a helper app. I have developed a small serial server that runs on a PC or Mac connected to the radio. The iPad app connects to the helper app over the network. The helper app simply forwards commands from the iPad app to the radio, and forwards responses from the radio to the app. It works well and costs nothing. Since most folks already have computers attached to their rigs, this would be the most popular option - I expect. Why would somebody want to control the radio from an iPhone or iPad with a PC or Mac connected to the radio? If I need to rely on a PC/Mac for the radio interconnection anyway isn't it easier to use this for rig control directly then? ;-)) Bigger screen, more comfortable, etc. To my mind a control app for a PDA (no matter what OS and/or manufacturer) only makes sense if you can use it real portable meaning no dependencies to other hardware or a network, just a simple 1:1 connection between PDA and radio.

Re: [Elecraft] KX3 Batttery life question..
When I lived in the SF Bay area I carried a 2-meter FM HT that I could use to access several repeaters in the area running 100 mW into a 5/8 wave mag-mount on the car. One of my favorite bits of fun with it was that whenever I was on top of Mount Diablo to service a commercial repeater, I'd take a few minutes to listen on the HT. I often worked mobiles in Sacramento, San Francisco, or San Jose, all between 40 and 60 miles away, running 100 mW, and often got full quieting reports! They were always astonished at the simplex signal strength, especially since most were running similar antennas and some were using rubber duckies in their cars. And that was with FM, which is clearly not the best weak-signal mode by a long shot! I would guess that places like 3800 foot Mt.

Re: [Elecraft] KX3 Batttery life question...
Well, I have to say, the possibility of putting options in the battery space, making the internal battery an option, appeals to me too. Then a good 2m transverter could go in the battery space and still be room for the ATU, might even be able to put the 100w PA in place of the battery, which seems to make sense, since the internal battery wouldn't last long with a PA 73 de M0XDF, K3 #174, P3 #108, KX3 #???

Besides being a QRP'er, Jerry was the web designer and maintainer of the first NorCal QRP Club web site and I believe he still designs and maintains some other QRP related web pages. His efforts are a great contribution to QRP activities and have certainly helped sell a lot of NorCal and other radio kits. It has been a while since I've seen him and he is looking good.

None of the arguments below will change anyone's outlook, but... Wayne wrote: The battery is very important; it makes the KX3 an all-in-one unit that you can quickly deploy in an emergency, ... In the 45 years I've been around ham radio, the probability that any HF ham rig would be used in an emergency has been vanishingly small, with the highest probabilities having been 45 years ago, not today. VHF or UHF FM use in an emergency is far more likely (but still even that's a very small probability). A module for two-meter FM in place of the battery would be a far better use of limited space, if an emergency-use argument is to have any credence. An emergency HF radio would, in any event, need to be resistent to harm from adverse environmental conditions *while in operation*. I don't think the KX3 will meet that minimally, at least as I've seen it at Dayton and Huntsville.

Because the most important issue follows next: What sort of chemical barrier will exist between the battery and the internals of the KX3 to prevent damage in the event of outgassing or leakage of chemical contaminants from the battery? If there won't be an impermeable compartment, that alone says Better keep the chemistry outside the radio! IMHO, of course. But...I'm looking forward to the KX3. It's the most exciting product I've seen in *all* my years in ham radio. My comments are not meant as an attempt to trigger *any* design change from whatever is now planned. At some point, an excellent product has to have its design frozen, regardless of continuing clamor from the unwashed. :-) Mike / KK5F __ 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] KX3 Batttery life question...
To each his own, but Mike Morrow wrote: In the 45 years I've been around ham radio, the probability that any HF ham rig would be used in an emergency has been vanishingly small, with the highest probabilities having been 45 years ago, not today A few years ago a ham in Oregon broke his leg hiking. He used a KX1 to call rescuers. I'm not kidding. VHF/UHF doesn't work at all in many mountainous areas, at least if you're down in a hole between peaks. For that matter, there are wide stretches of the West with no repeaters. NVIS on 40 m with a wire-in-a- tree or a backpacking dipole will often do the job with just a few watts. The clincher is that the end of the world is coming (!). I heard this on a shortwave station, thanks to the KX3's general coverage receive. An emergency HF radio would, in any event, need to be resistent to harm from adverse environmental conditions *while in operation*. Around here the most likely emergency that would cut off communications is an earthquake. Small radios stored in bags are likely to survive and be quite useful. It's buildings that suffer. An emergency HF radio should also *not* be a QRP rig...at least no rig *designated* as an emergency radio. I routinely check into a 40-m net and get good reports during the daytime with a short antenna 15' off the ground and 5 watts. HFpackers often running 10 W or less check into daily nets on 17 m and 20 m and work stations thousands of miles away. If there's a will, there's a way, and QRP will often get through. Even when it doesn't, it's fun trying. An emergency HF radio should also have sufficient battery capacity for more than just a few hours of intermittent operation. Depends on what you mean by intermittent. If my KX3 gives me 10 hours of casual operation at 3 watts from a 2500-mAhr battery, surely I could maintain useful communications during an emergency by being even more judicious with my transmit time. That said, a small, collapsable solar panel would be an excellent addition to the station. It can power the KX3's internal battery charger. On a *short* hike, carrying a 4 AH battery which prudence mandates won't be much of an impediment. I've done that many times, even when I used SWL's small DSW-20, -30, and -40 units. I travel *really* light. On day hikes my entire station weighs about 1.5 to 2 lbs, allowing me to carry two cans of beer rather than one. On a long hike and overnight stay, a 4 AH battery will be mandatory, unless one enjoys the dead weight of the KX3 and antenna after the internal batteries are depleted. 5-10 hours of operation from a charged 2500 mA internal battery is sufficient for all but the most boring business trips or hikes. I'm usually hiking (or businessing) a lot more than hamming. 73, Wayne N6KR __ 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
