Re: [Elecraft] Alternative battery for K2?
Don Wilhelm w3...@embarqmail.com writes: The charging scheme for the K2 internal battery is based on using an SLA battery. If the battery is changed to another battery chemistry, the charging circuit would have to be modified to match the charging requirements of the replacement battery type. Since Lithium batteries require very special charging techniques, this is a matter that is not to be taken lightly. A simple replacement of the K2 SLA battery with another battery chemistry would have to be a redesign of the charging mechanism. Don is of course right about simply putting in a battery with different chemistry. But, there are LiFePO4 batteries with integrated controllers specifically made so that they can be substituted for lead acid in existing equipment. Basically it has a charge controller for the LiFePO4 that operates on the charging voltage for lead acid. This item replaces the 7Ah size; I don't know if there's an equivalent item for the size in the K2. http://www.amazon.com/A123-Systems-ALM-12V7/dp/B008VVO6LE/ref=pd_sim_sbs_328_12?ie=UTF8refRID=0R6H1NBH31JQ509VCJ3V (I have not tried this; I'm still a lead-acid using dinosaur.) 73 de n1dam __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] [SPAM?] K3 TX calibration fails after KXV3B and SYN3A upgrade

[Elecraft] Mic - VOX interaction
Setup for RTTY using AFSK and VOX was easy with my original K3. Not so much with the K3S. What I've noted is that with the new internal sound card the Line Level is much fussier and the apparent gain requires lowering the Windows slider to about 25% vs. 50% on the laptop sound card used with the old K3. This isn't a surprising or insurmountable issue, but does make it more difficult to get a flickering ALC bar. Without care I get a hard over 7 bars reading. But a more puzzling issue is the fact that while doing this experiment, I discovered that the VOX gain is dependent on the Line Level/Mic gain. This has made setup even more hair triggered. If I lower the Line Level to get flickering bars, I must increase VOX gain and then it's way too sensitive on SSB. After investigation, I've found this to be true on both radios, although I never noted it before on the old K3. IMHO VOX should operate in parallel with the TX audio, not in series. Perhaps one of the geniuses at Elecraft could fix this in firmware, if not could we at least have VOX gain saved by mode?

Re: [Elecraft] Alternative battery for K2?
I soon (12-13 years ago) decided I didn't want a battery inside the K2 -- so it was removed and only external batteries used. I was overly(?) concerned about leakage and such issues.

[Elecraft] Need testers for new KX3 firmware allowing 10 W output down to 10 V supply
Hi all, We have a new field-test release of KX3 firmware (rev. 2.34) that will let you set power output as high as 10 watts with a supply voltage of as little as 10 volts. Previously, settings over 5 watts required a supply voltage of 11 V. This change will be especially useful when the rig is powered by a 3-cell Li-ion battery pack (typically three 18650 cells). Such packs initially put out over 12 V, but quickly drop to about 11 V. By the time they get to 10 V, they're nearing end of charge, and you really do want to drop to 5 W at that point. But while they're in the 11-V range, up to 10 W is practical. We still recommend the use of higher supply voltages when available. But you'll now be able to get that extra 3 dB in the field when if really need it. If you'd like to give this firmware a try, please email me directly. If I don't get back to you, don't worry -- the new code will likely be promoted to beta status early next week. 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3
When my sometimes SO2R-capable station is set up for SO1R and remote operation, I parallel two band decoders across the K3 ACC and power them on one at a time to select antennas for either an Alpha 87A or a KPA500 connected via ANT1 and ANT2. I parallel the key and PTT lines as you contemplated and so far haven't needed steering diodes there. I can thus operate either locally or remotely with my choice of amplifiers. I find that I use the KPA500 most of the time, warming up the big amp only when I want to break a tough pileup or go all-out in a contest. The KPA500 is so convenient! BTW, KPA500 Remote is a better control panel than the physical panel on the amp itself, and it operates either locally or remotely. Ditto KAT500 Remote. Both are free downloads from Elecraft. 73, /Rick N6XI On Sun, Aug 16, 2015 at 2:46 AM, Mike VE3YF m...@ve3yf.com wrote: Thanks to all that have replied to my question.

[Elecraft] KX3: Cleaner audio with Yamaha CM500, also PTT
There's still another Koss headset - Model KS-45 that's plug-in compatible with the Yamaha CM500. It has an electret mic. Also about $25 on Amazon. Look also at Amazon's listing for a RoverBeats Bravo. Electrically and functionally (and sound) it's interchangeable with the CM500 and - for us REALLY CHEAP hams, it's only about $10. Well worth a try. All three of these are look-alikes and have electret mics and the same wiring and 3.5mm plugs. They sound almost the same plugged into the rear jacks on my K3 (with bias turned on.)

[Elecraft] AntLion ModMic with K2
Has anyone used the AntLion ModMic with a K2? I'm currently using a Logitech headset with boom mic and it works fine, except I had to make a hb inline mic preamp to get enough drive. The AntLion ModMic looks very nice (a clever design) but I hate to drop ~$50 if it is also going to need a preamp. If you have experience with this mic, I'd like to hear what you found. 73, Lenny W2BVH K@ sn 1520 __ 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 Message delivered to arch...@mail-archive.com

They sound almost the same plugged into the rear jacks on my K3 (with bias turned on.) No surprise. BUT -- how comfortable are they? Have you worn them for a weekend contest full time? My Sony MDR7506 and the CM500 pass that test with flying colors. Have you gotten any reports from CRITICAL listeners about how the mic sounds? Several years ago, I browsed a big Fry's store for boom mic headsets, with the objective of Skype for the XYL, and bought a couple rather different cheapies. The mics sounded barely OK, the phones were about the same, and were VERY uncomfortable. And this caution: The Koss mic is described as noise cancelling. True noise cancelling mics must be talked very close to work, and they don't sound very good. If the mic is simply a cardioid, it has a different problem -- an overemphasized low end when worked close, which wastes TX power, emphasizes breathe pops and handling noise. People who sell this stuff and write the ad copy almost never know the difference, and often use the wrong words to describe what's going on. For example, Yamaha's own description of the CM500 called it a dynamic mic, while it definitely an electret. I suspect that the mic in the Koss is an electret, simply because electrets are cheaper than dynamics, and these are cheap products we're talking about. :) The challenge, of course, is to separate the good cheap from the bad and not very good cheap. I've not seen the Koss products, so have no opinion as to their quality. 73, Jim K9YC __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Alternative battery for K2?
I had a 4 cell LiFePO4 battery inside my K2 for quite a while. It was about the same size as the original SLA. I found that I was able to charge it with the built-in SLA charging circuit as a matter of routine and the cells remained in balance, as verified by an occasional balance charge with a CellPro Multi4. The reason this worked well was because the cells in the pack were all of good quality, the discharge rate was not excessive, the built-in K2 charger charged at low current, and I was careful not to leave the charging circuit on for prolonged periods. LiFePO4 will tolerate limited low current overcharging fairly well and without the danger associated with doing the same with regular Li-Poly chemistry, and in my experience without damaging the cells. Of course, ultimate cell life may be only 500 cycles instead of the 2000 you might expect with good LiFePO4 cells and use of a quality balance charger, but I never found any degradation. I agree with others that have replied, however, that just using an external LiFePO4 pack entails little disadvantage, and that is what I do now myself.

Re: [Elecraft] K3 TX calibration fails after KXV3B and SYN3A upgrade
Wayne, Huge thanks for interrupting your weekend. I see Doug EI2CN has already taken the words out of my mouth re Elecraft support - it is indeed awesome and impressive. All understood and I'll work through your suggestions later this evening/tomorrow morning my time. I'll get a dossier to K3 support in time for business hours Pacific time tomorrow. 73, David G3WGN From: wayne burdick [via Elecraft] [mailto:ml-node+s365791n760635...@n2.nabble.com] Sent: 16 August 2015 19:38 To: David Aslin G3WGN da...@aslinvc.com Subject: Re: K3 TX calibration fails after KXV3B and SYN3A upgrade David, The KXV3B itself should have nothing to do with this unless it is damaged or installed incorrectly. Also, many K3 users have this same hardware setup along with rev. 5.33 firmware. So I suspect a firmware configuration issue. Make sure you're not in TX TEST mode; have crystal filters configured correctly; have the SUB IN board installed correctly (if applicable); TUN PWR set to NOR; TX ALC ON; 2-TONE OFF; TX INH OFF. Also try removing the sub RX (if applicable) and reinstalling the bypass jumper for the sub-IN module. Get it down to the simplest configuration possible. Please send all of the info to k3support and they'll contact you on Monday. 73, Wayne N6KR On Aug 16, 2015, at 11:16 AM, Dave G3WGN M6O [hidden email]/user/SendEmail.jtp?type=nodenode=7606356i=0 wrote: Mike (and all who have sent replies on and off reflector) - thank you.

[Elecraft] KX3: Cleaner audio with Yamaha CM500, also PTT
Jim, it's true audio quality is very subjective. For good communications quality, I personally judge the three headsets I mentioned to be about equal. Over the ear comfort also compares with my over the ear headphones - a sauna for the ears. :-) Brian, Yes, the electret mics do require a small amount of power - Elecraft and others call it BIAS voltage. Fortunately - with the K3 and K3S and very likely the KX3 also - that needed bias is available and can be turned on or off with a menu selection. __ 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 Message delivered to arch...@mail-archive.com
