Re: [Elecraft] The List (amsct...@comcast.net)
If you use a mail-reader that supports threading, you will be able to sort your messages automatically by who replied to whom. If your mail reader doesn't support threading (and most do) you can still see the conversation threads by reading your list at the on-line Nabble site. You can reply there too, and as a bonus, the topics are sorted by major field of interest (K3, KX3, QRO, HAM, Off-Topic, etc). Please do check it out if you're not finding reading the mail in your mail program to be a pleasant experience.

[Elecraft] [K3] MCU 4.47 serial recovery
I've noticed that the ability of the K3 to recover from disturbances in RS232 isn't what my memory of it used to be. For example, if I start a second program sending query commands the the K3, I can never get it to answer any more serial commands. My belief is that it used to eventually get back in sync. I've verified this with my own serial programs and also with k3util. For example, when it's stuck, it won't reply to FA; at all until power cycle. (Other rig operation other than RS232 is unaffected.) I don't know if it's related to the input parsing code in the K3 or if it's related to some DTR state that gets asserted briefly during the serial port open. But I can't find any reliable way to clear this other than rig power cycle. Resetting the K3 baud rate from the front panel, for example, doesn't cause it to come back.

Re: [Elecraft] [K3] MCU 4.47 serial recovery
Thank you, Wayne. Changing the retry interval from 50ms to 250ms seems to fix the problem I encountered, which in more detail was this: When an unrelated program strobes the RS232 ports (looking for compatible devices) it gets the K3 out of sync. With the longer retry delay it gets back in sync with the rig control command stream. Should I default the update the fldigi rigcat defaults for the K3 to 250ms retry, 10 retries, 100ms write delay? We're presently shipping 50ms timeout, 5ms write delay, 2 retries with fldigi rigcat control.

To disable TEST mode, press and hold TEST. * You have selected the separate RX ANT jack on bands 160 and 20m. While it is common to use a separate RX antenna on low bands, it is likely you have selected it by accident on 20m, which is the current band your K3 is set to. To disable the RX antenna on a band and antenna selection, select the band and ANT1 or ANT2 (with ANT) and press RX ANT. * DIGOUT1 is enabled on 40m ANT2 and you have a KPA500 connected via the ACC able. DIGOUT1 is a pin on the 15-pin ACC cable. This will disable the KPA500 on 40m/ANT2. To change this setting, select 40M and ANT2 and hold CONFIG and change the DIGOUT 1 setting. * Filter 5 Center Frequency Offset is Zero Filter is is an Elecraft 200Hz filter and it has a non-zero Frequency offset. While this is possible, it is more likely that you have not yet set the frequency offset. Consult the package that your filter came in and look for the offset frequency. Select Filter 5 with XFIL and then hold CONFIG and select FL5 FREQ and set it to the value specified. * XIT is enabled and non-zero XIT will cause your transmit frequency to differe from the VFO dial frequency by the amount shown in the VFO B display when you rotate the RIT/XIT knob. You will see the green RIG/XIT led is lit, as well as the yellow + or - LED. To disable XIT, tap the XIT button. * SPKR+PH is NO SPKR+PH is set to NO, which disables the K3 speaker. If you have no audio, but your headphones work, hold CONFIG and navigate to SPKR+PH and use the VFO knob to set the value to YES.

Re: [Elecraft] KpA500 to K3 band change,fault/status
The K3 has a per-band/per-antenna DIGOUT1 line on the 15pin AUX connector. If you use the Elecraft 15-pin AUX cable, DIGOUT1 is tied to the KPA500 inhibit line. So, DIGOUT1=ON means AMP INHIBIT=ON. For example, if you have a SteppIR (which can be resonant at 40m and up) on ANT1, you can set DIGOUT1=ON on ANT1 for all bands 30M and below, and it will never key the amp on the low bands for that antenna. If your have ANT2 connected to a 40M dipole, for example, you could set DIGOUT1=ON for ANT2 on all bands except for 40M. Even if you have a high-power external ATU, you might still want to set DIGOUT1=ON for 60m and 30m, (though the US does allow up to 200W on 30m).

Re: [Elecraft] Still lacking
I'd suggest LiFePO4 batteries, as they can source the current necessary for the transmitter easily, and are safer in operation than Lithium Polymer. They can be safely charged on a portable solar panel if you disconnect once the voltage reaches 14.4v, and that's pretty much what the SLA charge controllers do as well. The 2.4 AH packs charge at about 1.5 Amps, so it's hard to bring too big a panel!

Re: [Elecraft] Still lacking
K7TV wrote: The battery can provide very high output current for a short time, I believe enough to power a 100 W transmitter briefly. Yes, LiFePO4 has a high power density but not as high energy density as LiPoly or the typical Li-Ion (laptop) batteries. It was chosen for the One Laptop per Child project, for example. The chemistry has a very flat discharge curve, and sources high current or low current, and retains its efficiency. For SLA, the capacity is rated at a discharge rate of 1/20 C, so a 7AH SLA battery will give you 1A for 7 hours, but any transmit at 20A would be well beyond its capacity. A 20AH SLA would give you 1A for 20 hours, and could give you 20A briefly, but not for 1 hour. But an 8AH LiFePO4 will have no trouble giving you 20A for 20-25 minutes solid key down. With SSB 40% modulation at 100W and transmitting 1 minute out of 4, that gives you 10% duty cycle, and because of the excellent properties of LiFePO4 you'd get a a couple of hours of operating time easily, especially with the low RX current draw of the KX3. Couple the LiFePO4 with a solar panel that can cover the receive current (about $50) and you extend your QRV to pretty much all day with an 8AH pack or a couple of 4AH packs.

Julian, G4ILO wrote: What are the advantages / disadvantages of this type of frequency standard over the Efratom LPRO-101 which is a rubidium standard? Julian, G4ILO I'm a duffer at this time/frequency stuff, but I've scored well enough at the ARRL FMT to get my call in QST, and I gave a presentation on it at the Bay Area Maker Faire last year, and a NIST scientist told me I didn't say anything egregiously wrong, so I'll try to stick to what I understand here. If you want to know more, go to Febo.com or time-nuts and read a bit (before you ask questions) and you'll find people with literally orders of magnitude more experience (and interest) than you ever thought possible. Both an Rb oscillator and a GPS-DO (and for that matter, your own Cesium standard) can provide you with a frequency output, but they're different types of things. A GPS-DO is a managed device with an output, like WWV or the grid 60 Hz (mains 50Hz) frequency. A Rubidium oscillator is like a quartz crystal, but more stable over the long term (modulo a well-defined linear drift), so once it's set, it stays set exceptionally well, though usually the phase noise isn't as good as a temperature-controlled quartz crystal. A Cesium standard is called a standard because it's how we define time; when properly adjusted, it will remain in calibration quite well. A GPS-DO usually contains a crystal oscillator which is controlled (disciplined) to match the data coming in from GSP satellites, which themselves contains Cesium standards which themselves are actively managed by the US government. So it's like listening to WWV or one of the other time signals on HF, but it uses the 1.4 GHz range and averages multiple signals, so you get better results with smaller propagation-induced errors. There are some Rubidium GPS-DO devices as well, some commercial and some done by smart hams, but even those, as far as I know, contain a quartz crystal oscillator which itself is disciplined by the Rubidium bulb microwave resonance. There's arguments about different ways of disciplining all of these oscillators and if you're interested, look for the time-nuts mailing list or read on febo.com, or read about Allan Deviation. But briefly: there are multiple sources of noise, and if you measure the noise on different time scales, you get different answers about how much noise there is. So, roughly, phase noise is at one end of the chart and how far your wristwatch is off at the end of the month is at the other end. What time scale you care about determines what type of oscillator you use and how you measure and take care of it. A Rubidium oscillator does quite well on many of these time scales, better than Cesium in some of them, but worse than a plain quartz crystal in others. Unfortunately, my guess is that buying an Rb standard and using it instead of the quartz TCXO in the K3 would result in worse phase noise which translates into a noisier band RX and noisier TX. Quartz is pretty much the way to go for transceivers given the areas of concern that hams have. (I.e., would you rather have 20dB less band noise or be able to get within 0.1 millihertz of the band edge instead of just 1 millihertz of the band edge?) More philosophically, we define time in terms of what Cesium does. Both Cs and Rb physics packages have knobs to adjust for external magnetic field (C Field), so both can be set wrong, but Rubidium bulbs age and change frequency (though at an fairly well characterized rate), so you can't substitute a Rubidium oscillator for a Cesium one. According to NIST, gravity is a big effect as well, so if you ever move one of your oscillators, its calibration field is toast. And finally, temperature control is of the utmost importance, and those who are serious use multiple nested containers for temperature isolation. For ham use as a frequency standard, in terms of phase noise performance, the algorithm used and the oscillator that's being disciplined (and how often, as part of the algorithm) has the strongest influence. For example, a GPS-DO is additionally affected by what satellites are in view (the constellation), and the Trimble units are affected by the changes more so than more expensive units which are designed as frequency references, because they make abrupt changes when the constellation changes, which is pretty much every few minutes as sats pass over. The eBay Trimble units in particular have trouble with this. They were designed for E-911 installations in cell sites, where they were used to calculate distance via speed of light to a mobile unit. My (unfounded, personal) belief is that it was more important that nearby units all had the same idea of the time than that they have reduced noise on the shorter-term. So they make more frequent adjustments to their internal quartz oscillators that are comfortable for a frequency standard, though a number of smart folks have figured out algorithm tweaks to mitigate this
Re: [Elecraft] [KX1] A LiFePO4 internal battery option
Those are 6.6v, so I guess you use a pair? I've been using LiFePO4 in a lot of things, but haven't seen these that fit in the KX1. At 700mAH they're a bit small, but the constant operating voltage is nice. You might take a look at these, which are available at Fry's and Amazon: http://www.powergenix.com/?q=products/nizn-quick-charger At 1.8v charged you get almost 11v out of 6 of them in the existing AA slots. Of course, you have to remove them to charge. The self discharge isn't as good as LiFePO4 but it's not bad either.

Re: [Elecraft] KX1 and K1 Battery Notes
I have had good luck lately with AA cells from PowerGenix. They are Nickel-Zinc, and start at 1.83 volts fully charged and are discharged at 1.8v. With 6 of them in my KX1, the internal voltage was about 10.8 volts. They don't have as good self discharge (about 10%/month) as the Lithium primary cells, Eneloop or LiFePO4/Nano-phosphate, nor as good energy density (about half at 1200mAH), but they can't be beat for internal batteries and voltage. They are available through Amazon, Fry's, and other such stores and sites. I bought two packs of 4, each of which came with a wall charger.

[Elecraft] K3 init macro feature request
I'd like to see a way to designate an init macro, like the callsign set. For example, I like the rig to remember the TX TEST state and always start up in TX TEST, but I recognize that such a feature might not be popular enough to warrant the development and codespace. However, it's easy to express this in the K3 command set and if I could specify a macro to run when the rig turns on, it'd be easy. I suspect there may be other settings that could be customized in this way.

Re: [Elecraft] Some thoughts on the K3 as an emergency communications station
I'd really like to see some LiFePO4 packs (or at least sheet-metal support for them) for the Elecraft rigs. The K2 would be fairly easy, and the KX1 as well and probably the K1. The K3 has room if there's no amplifier, but LiFePO4 shines in power density, which is just want you need for the current peaks of a KPA3, so some sort of rear bolt-on would be needed. I use a 1200 mAH pack on my KX1, but that's too big to fit internally.

Re: [Elecraft] K3 and USB Audio Codec
Kok Chen wrote: One good connection that I have come across is S/PDIF that is available on the Icom IC-7800. It allows a connection between the radio and the computer that is completely non-galvanic. No ground loops, no RFI, down to -144 dB. S/PDIF provides an audio path with up to 20 bits of resolution (about 120 dB, with 1 bit being 6.02 dB), with 24 bits being an option by using the extra 4 steering bits as data. The standard sampling rate for S/PDIF is 48,000 samples per second stereo, which would support almost 50 kHz of bandwidth on an baseband I/Q channel. S/PDIF provides up to about 30 feet separation between equipment. I built an amplitude-modulated IR fiber link using cheap parts and got poor results due to fluorescent light leakage into the jacketed cables. I've tried hard to find available chipsets for S/P DIF but come up short. A well-shielded box or internal optical connection for radio would be a nice thing to have for ham equipment.

Re: [Elecraft] OT Carrying radios on commercial flight
I quite recently flew to Europe from California, and back, with a KX1 and an HT and Buddipole (in suitcase). I put a copy of the QRP Quarterly in my backpack, as it has a big ad for the KX1 in it, but they didn't look. Operating QRP in rural Europe is interesting: there was no noise, and I could hear plenty of signals from Europe and the US East Coast, but I was below everybody else's noise floor.

[Elecraft] 30m DX report with KX1 and K3
I took my KX1 outside to see if I could track down a router-ish noise on 20m, and when I couldn't I switched to 30M as I was using a 30M MFJ short loaded whip. I heard SM4OTI booming in. I put the KX1 on top of the car for ground and gave Steve a call, but no joy. I came inside and got an QRZ 5N answer with 5W from my K3 and SteppIR short dipole, and completed the QSO with 25W. So maybe the solar flare is clearing!

Re: [Elecraft] Using Buddi Pole Deluxe Antenna with K3
You might try the Buddipole users list, which you'll find at http://buddipole.com/documentation.html The Buddipole is (usually) a shortened, high-efficiency antenna, which means that it is relatively narrow-banded. It's fed off-center to bring the real component of the impedance up, but on the lower bands it has a real impedance of less than 50 ohms. So, it's best to use the coils to tune for resonance (X or reactance = 0) and then use the ATU at that point to match the real portion of the impedance. They also sell a matching transformer which does a better job, as it's at the antenna end, but it's an additional purchase. So, I'd recommend putting the K3 ATU in bypass, setting up the Buddipole as the instruction card says, and try moving the tips in and out a few inches to see what the SWR is. If you use the ATU to lower the SWR when it's way too high, the Buddipole won't be doing its job. For vertical or horizontal, you'll find mostly that vertical is best for the high bands and horizontal is best for the low bands for DX (though you'll want to use a wire instead of an arm for the ground side). Horizontal can work for 40M NVIS local communications where you plan to aim the signal straight up.

Re: [Elecraft] Elecraft Digest, Vol 71, Issue 15
I have a number of different USB RS232 interfaces, plus a four-port PCI serial card (of which only two ports work under Linux). Recently I tracked down a broadband noise to one of the USB ones I'd been using to control a rotor. It didn't make noise when the device was in use, but if a program opened the serial port for the rotor and left it open, it would make noise. So it was difficult for me to track down, because only certain programs would open the rotor port and leave it open.
