[Elecraft] K3: antenna dependent transmit power
Hi, Is there any way to set the transmit power level based on the antenna setting on K3 (i.e., ANT1 or ANT2)? I have two antennas (connected to ANT1 and ANT2) that have different maximum power limits and would like to make sure that I don't fry anything when switching antennas. I know that this is a per band setting but it would be great to have it antenna dependent as well.

[Elecraft] K3 firmware updates under Linux/ARM?
Hi, As the current Linux/Intel desktop at my station decided take its last breath, I am exploring the option of replacing it with an ARM based system; either Banana Pi (ARM based computer; about $45) or Raspberry Pi2 (about the same for $35). I have figured out everything else (dual monitor support, USB-RS232, logging programs etc.) but the only missing piece is to be able to update the firmware in my K3. The firmware update program is available only for Linux/Intel platforms and not for Linux/ARM. Are there any plans to support Linux/ARM in the future? At this point it would be enough for me to hear that such support is planned.

I'm not sure how well a Qemu x86 VM would perform on a mini ARM rig like a Raspberry Pi or Beaglebone. Qemu can only run on one core. That is, it can emulate multiple CPUs, but it does this in a single thread, IIRC. And I suspect getting it up and running would be a challenge. A better option might be Exagear Desktop. It is like Qemu but much faster. Like 4x faster. But it is not free ($30). Exagear Desktop on a Raspberry Pi 2 Model B should run 32-bit Linux x86 applications nicely (like the Elecraft Utilities). I figure Exagear is worth the money just for the performance advantage. It could be an awesome little system for around $75 (if you already have a HDMI monitor and a keyboard). I've been seriously considering ordering one just to play with. I just tried to boot 32bit intel fedora 21 live image under ARM qemu (on banana pi). This is REALLY slow and even speeding up by a factor of 4 is not going to help much. I did not have enough patience to get the whole thing to boot up to the desktop, so I concluded that this will not work in practice. It shouldn't be that difficult to cross-compile the K3 utility for ARM (unless they are using some strange development tools that don't support this). Since everything else works now, I will go the ARM way with my station. If I need to update the K3 firmware, I will visit someone with a PC. Hopefully Linux/ARM will be supported in the future.

[Elecraft] K3 VFO tuning noise on 10m RF gain
Hi, I have a recent K3 (SN 6527, FW 4.51) and I see fairly strong VFO tuning noise on 10m. More specifically this is centered around 28.004 MHz and spreads around for about +- 3 kHz. With the preamp on this can reach S3 on the meter while tuning (well above the noise level with antenna on). Not that it is going to prevent me from working there since it only comes while tuning but it is annoying. There might also be other spots on the band but I work CW only, so the above is something I run into frequently. Any ideas how to fix this? Another small problem that I have is that the RF gain behaves in a bit unpredictable way when turned all the way down. When I start turning it down, I see the normal behavior, the S-meter starts going up. When I reach a position (about 10% of minimum), I see the S-meter drop down and it seems like the RF gain is going up again. Is this a problem with RF gain calibration (googling around suggests this)? And if it is, what could have caused it to go out of whack? (this was a factory assembled K3 that I bought about 6 months ago). I probably need a signal source to recalibrate? Other than these two issues, what a great radio! Really enjoying it!

I agree with Phil, this will never bother me. Perhaps this varies from one rig to another? On mine I can definitely hear it even with the band noise present (I always use phones and work with fairly weak signals lurking in the noise). When browsing the band quickly, it is possible to miss a weak station because of this. I have a decent antenna hooked up to it - an inverted V, which is abt 50 feet up from the center, so there is significant band noise present. I have the preamp on pretty much at all times on 10m. I wonder if there are some factors in the assembly process that could affect this (routing of cables etc.) ? I think I have also noticed that the amplitude of the tuning noise varies (not related to the noise level of the band) but I still have to verify this observation (this could still be my imagination). As for the question about the RF gain - I probably need to calibrate RF gain again. It would be great to know how it got messed up - it could have been from the very beginning - I might have just missed it.

Re: [Elecraft] Firmware upgrades using Ubuntu 12.04
Let me give one OT RANT, and then I will shut up on this subject. Suffice it to say that I have been extremely disappointing in all Linux distributions because of the lack of any organized support fort the users - the attitude seems to be if you don't already understand the nuances of Linux, we will shame your questions and be very unhelpful. Check out the various forums and FAQ lists to verify this attitude. I have tried Ubuntu, Linux Mint, and Debian in the recent past, and have found that unless you wish to spend a loot of time in geekdom study, the terms are cryptic and not logical acronyms, and the user groups are useless unless one is already fluent in their brand of geek-speak. Yes, I am computer fluent in Windows and peer-to-peer networking - I have worked with PCs since the Apple II days and the IBM PC DOS systems are no stranger to me, but the Linux groups are just not helpful at all to those who do not understand their peculiar cryptic language. In other words, there are no clear and concise instructions for Linux. The Man pages are supposedly the answer, but they offer geek-speak explanations for those who are not initiated and expert into the Linux brand of geekdom. I know, there are many who will disagree, but you will have to point me to a (non-on-line) manual that I can use as a reference book and is similar to those like Mastering Windows XP Professional, Linux in any distro is just not going to make the grade. For those who simply want to do email and surf the web, Ubuntu is great, as is Linux Mint - it has all the tools those users need, but for those who want to do such things as network a Linux workstation into a Windows peer to peer network, there is just not enough explicit information about how to set it up and make it work. Windows peer-to-peer is native, but with Linux, it is a complex add-on that I have not been able to master after several attempts with Samba configuration. I don't think these quite belong to the Elecraft list but since this already took off... If you can't understand how computers work, use what ever you can. Linux (and Unix in general) is superior to anything made my microsoft pretty much from every aspect. Talking about these two at the same time is like comparing ham radio and CB. Just my $.02, Jussi Eloranta (AA6KJ) ps. BTW Setting up samba is trivial - takes about 3 minutes. There are many step by step instructions on the net. __ 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

Right now I am very limited putting anything decent up without serous safety concerns.

The abstract of the debunking research (thanks Sverre for posting) explicitly refers to OAM. Indeed photons can posses orbital angular momentum which can only interact with materials that have fairly special anisotropic properties (which is the reason I was not even bringing it up earlier). In order to talk to the oam component, one should subject RF photons to propagate in such medium as well. While possible in theory (and shown in optics using an obscure version of a halve wave plate), it would be a real challenge to observe this for RF where such materials are not available (someone correct me if I am wrong, I mostly work with optics). However, an interesting topic and well worth looking into! I wonder if photon orbital angular momentum would be conserved in a non-linear process where the difference and sum generation occurs (usually just the sum is used, for example in second harmonic generation; similar to RF heterodyning) and the difference component would lie in RF (OK, perhaps in GHz range in practice...; near baseband anyway ;-)? So the idea would be to start with optical photons (prepared with oam information) at close wavelengths and then convert to RF (RF wavelength = difference between the two optical photons; angular momentum must be conserved). Unfortunately, this would not work for detection that well because high intensities are needed for the non-linear process. I would expect that the first place where this would show up (if possible at all) for RF would be nuclear magnetic resonance (NMR) experiments where I could see that the extra source of angular momentum could find applications there.

On 05/03/2012 10:10 PM, Erik Basilier wrote: The May 2012 issue of the IEEE Spectrum magazine reports that researchers in Italy and Sweden were able to conduct two separate instances of radio communication on the exact same frequency, without increasing bandwidth, and without time-division multiplexing, be making the transmissions differ in angular momentum. One transmission used linear polarization, and the other was given angular momentum by means of a dish with a radial cut, where the metal was bent backwards/forwards on the two sides of the cut. Apparently this is not just a case of linear vs circular polarization, as circular polarization can be readily picked up by a linearly polarized antenna, and apparently the two channels did not interfere with each other. The researchers claim that this demonstration points to the possibility that the radio photons can be given multiple, quanized levels of angular momentum, making possible several more communication channels without increased bandwidth. Other researchers say that this is just a form of MIMO. Wikipedia describes MIMO as the technique of using multiple antennas as in diversity reception or in gain increases obtained by phasing the antennas. The only source of angular momentum in a photon is its intrinsic spin ( = 1). This can have two projections, +1 and -1 (only two, unlike for most spin one particles, which have three possible projections). However, these two projections are directly related to the left and right circularly polarized light, so I cannot quite see what other source of angular momentum could arise in this case? Having said this, I don't quite believe in the Swedish group explanation of this experiment.
