For a single radio setup, I used a single 12V battery of the biggest that Costco sells, about 80 AH. Solar is useless for me during the winter because I'm surrounded by VERY tall redwoods, whose shadows limit my sunlight at panels to a few hours per day during the winter and 6 hours during the summer.

Uninterrupted communications is a very important concept IMHO. A trick (or maybe not) that I have recently used to address the charging issue, is to use a ‘Solar Charge Controller’, of the appropriate amperage rating, of course. These devices have a solar input (suitable for a Linear type power supply. Not quite sure how it would behave connected to a switcher), a Battery Interconnect, and Load out. Many devices include charging control circuits that you can match to your batteries fairly well, and a Low Voltage Disconnect (LVD) to keep your batteries from over discharging. I have this setup on my K3 and it works great. I have the K3’s Low Voltage warning set to .3v above LVD cut-out (on the charge controller). This lets me know when the batteries are close to the bottom. This is a great feature that helps you with not destroying your batteries.

Re: [Elecraft] KX3 Transmit audio has (unwanted) echo effect
Jim, I have also had these reports when I tried to use a dynamic mic such as a EV664A and Heil PR22, it gets pronounced at the mic gain and compressor is turned up. I don't think there is any setting you turned on. Because of this I have gone back to electret mics. Will be watching to see what sort of responses you may get back.

Just got my K3 a couple of weeks ago after being QRT for about 4 years; the rig is an absolute joy! For an antenna I run an Inverted-L 120 ft long, up 30 ft at each end.

Re: [Elecraft] 9M6XRO with my K2/10
Congratulations! It is very exhilarating, isn't it? QRP DXing isn't always easy, or successful, of course. I've been running QRP mostly for the last year, with a rather modest dipole at ~32' for an antenna. Every once in awhile, you get through on one or two, or a few calls. Sometimes you get through but after waiting your turn. Sometimes the pile up is so fierce you never get through before you give up and take your business elsewhere, or he does. But, if the DX has a decent signal here, and the pile is not too large, you can usually get in there, with patience From what I recall of my C-line/L-4B/giant quad days, it was gratifying to get yourself in the log but you expected to, and very quickly too. This is different, a triumph of a different sort, maybe operating prowess is substituting for raw ERP or something, that puts a smile on your face, a song in your heart, and a spring in your step! The Old Timer often taught that the secret to working DX is when you hear 'em, call 'em! It's just that simple. 73 de W6OGC Jim Allen Sent from my iPad On Dec 21, 2014, at 10:59 PM, Bernie KF0QS ham...@ix.netcom.com wrote: Today, there was a pileup on 9M6XRO (East Malaysia) on 10 meters.

[Elecraft] KPA500-KAT500-K3 problem
My K3-KAT500-KPA500 has been working fine for 5 weeks now. (added the KPA500 Nov. 10, 2014) Last night I had to move some cables around with in the rats nest behind my K3. Unrelated cables, so I thought, they were for the VGA output for the P3 to add a data switch before the external monitor. After the move everything was still working just as it should. I shut down for the night. When I turned everything on this morning the K-Line has started acting strange. The K3 no longer flashes the KPA500 line across the VFO B window. I have CONFIG: PWR SET = Per Band, *BUT* the K3 no longer has 2 power settings (one for KPA500 in op and one for KPA500 in stby) However the KPA500 *does* change bands with the K3's change of Bands. The K3 does flash the KAT500 line in the VFO B window. The KAT500 does change antennas as related to the band it is on. The KAT500 no longer knows I have moved the K3's frequency within a band, so no longer (pretunes) to that new frequency. and Yes CONFIG: KAT3 shows KAT500y The KAT500 tunes fine when it is in AUTO and sees rf. I even went back to a previously saved K3 configuration. I unseated and reseated the KAT500 to KAT500 Cable. To summarize, I have lose the safety feature of the K3 knowing it has a KPA500 so it doesn't have 2 drive levels, and the KAT500 no longer pretunes to a new frequency when the K3 is moved to the new frequency within the same band.

Re: [Elecraft] KPA500-KAT500-K3 problem
Sam, I run the KX3 line: KX3 to a KXPA100 to an Ameritron ALS-600 to the KAT500. Little lines all over the place, and hi-power LMR-type coax out of the linear. Cardinal rule, I am told, is to avoid those high power RF coax cables as much as possible in proximity. For instance, never drape a control cable or a display cable across the coax. You’ve probably tried all of this, but my two cents.

Re: [Elecraft] KPA500-KAT500-K3 problem
The KPA is still set for RADIO= K3, right? Shortly after power up, the KPA will send its on state to the K3 using the Auxbus, but only if it is told the radio is a K3. The symptom is that this is not being received by the K3. The logical conclusion is that something is blocking it. Nothing messed up on pin 2 of the AUX cable, right? I don't remember if the K3 must be told about the KPA (don't think so, but that would have been long ago...), but if so make sure of that setting.

[Elecraft] KX3 CW Weighting
After receiving a 459 report during a CW contact this week, it occurred to me that I had never actually listened to the transmitted CW signal from my KX3. Doing so, I discovered the CW weighting was set heavy by my ears (1.25), quite a bit different than what the CW sidetone represented, and possibly contributing to the readability report. I reset the weighting to 1.05 and the CW output now sounds exactly like the sidetone spacing. For those KX3 drivers out there, you may want to either listen to your transmitted signal, or simply trust my assessment and set menu CW WGHT to 1.05.

Re: [Elecraft] KPA500-KAT500-K3 problem

Re: [Elecraft] KPA500-KAT500-K3 problem
Yes RADIO is still set for K3. Last night I had never even touched the cable that went between the KPA500 and the KAT500.

The logical conclusion is that something is blocking it. Nothing messed up on pin 2 of the AUX cable, right? I don't remember if the K3 must be told about the KPA (don't think so, but that would have been long ago...), but if so make sure of that setting.

[Elecraft] K3 DC Output

Re: [Elecraft] KPA500-KAT500-K3 problem solved
Connection to Pin 2 somewhere in the K3 to KAT500 cable is broken! thanks to *all* who pointed the way to troubleshooting the problem!!! On 12/22/2014 10:51 AM, Jack Brindle wrote: I just went back and read Sam's original post. Both KPA and KAT are affected. This comes form the info that the KAT is not following the K3 frequency, info that only goes through the AuxBus. The problem is either the cable from the K3 to the KAT, or somehow the AuxBus has been disabled in the K3. I don't think the latter is possible. We know that the band lines on the AUX cable are working just fine since both KAT and KPA follow the K3 band. both boxes get the band from the BAND lines and not the AuxBus (note for Sam - the KPA does not listen to the AuxBus, only talks. The KAT does both). So, check the cable from the K3 to the KAT. Pin 2 appears not to be conveying data. You might want to pull it and ohm it out. Also note that this must not be a VGA cable, but a straight-through connection with no lines shorted together. But you already knew that... We will get you going shortly.

Re: [Elecraft] K3 13.8 VDC power
Wow, thanks to all for the greatly informative answers. I gleaned many good ideas from them. This is my concern; I am interested in protecting my K3 from damage by not being shut down properly should a power interruption occur while the K3 is operating. For this design, I'm thinking about a worst case scenario; in transmit mode at 100 watts/20 amps, plus accessories on. I am concerned about Hydrogen gas while charging a lead-acid battery here in the furnace room. Since I don't need to operate by battery power, I'd like to know your thoughts about if a Gel-Cel battery of a 9 amp variety would handle the 20 amp load until I could go to receive mode and properly shut down? I haven't had any experience drawing that much amperage from a gel-cel momentarily. I don't know if the load voltage would be adequate to keep the K3 alive.

Re: [Elecraft] K3 13.8 VDC power
Dick, Yes, hydrogen outgassing is a potential problem, and the area containing a normal lead-acid battery should not only be protected from sparks and ignition sources, but should also be vented to the outside. I would suggest that you look at a larger gel cell or an AGM battery. If you use a normal lead acid deep cycle battery, you could enclose it in a tight battery box (often used in RVs) which has a vent hose that you could route outside. 73, Don W3FPR On 12/22/2014 2:51 PM, Richard Fjeld wrote: Wow, thanks to all for the greatly informative answers.

Concerns about outgassing notwithstanding, I've never used anything more than the voltage regulator on the power supply to limit the charge, and I've always used ordinary deep cycle batteries. The key is to limit that voltage to what the battery expects, and to limit the charging current to what the battery will take as a trickle once it's reached full charge. Those are not difficult to do if you simply monitor battery voltage and charge current. 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] K3 13.8 VDC power
Dick: Unless you are looking for something to do, I also suggest you are over concerned. During the recent CQWW CW on the island of St. Croix, we had 3 K3s all driving amps. We probably had 3 or 4 outages without incident. Similarly, as a single op on the island of Montserrat during the last ARRL SSB, I had a K3 barefoot. Again, something like 3 or 4 power outages during the contest. No problems. Once that 12 volts into the K3 reaches its lower limit, the radio's off. Shutting down properly during a power interruption might be a different, and more difficult requirement, than just batter backup. 73 charlie, k1xx On 12/22/2014 2:51 PM, Richard Fjeld wrote: Wow, thanks to all for the greatly informative answers.

[Elecraft] KAT500 and KXPA100 tuner problems

Re: [Elecraft] K3 13.8 VDC power
Dick: A few more notes. Outgassing is not a normal occurrence of lead acid batteries. It occurs when there is substantial overcharge. That is why you always use a regulator so outgassing doesn't occur. Second SLA stands for sealed lead acid. These batteries are partially sealed to prevent outgassing. They do have blowout plugs to prevent explosions. Finally there are battery monitors available at reasonable cost. They will sound an alarm if your battery voltage is too high or too low thereby giving warning that something is not right. I also attach a 12vdc LED light strip to my power alarm. That way when the house lights go out I can still see the controls to shut things down if need be. 73, Fred, AE6QL -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Don Wilhelm Sent: Monday, December 22, 2014 12:06 PM To: Richard Fjeld; elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 13.8 VDC power Dick, Yes, hydrogen outgassing is a potential problem, and the area containing a normal lead-acid battery should not only be protected from sparks and ignition sources, but should also be vented to the outside.

Re: [Elecraft] K3 13.8 VDC power
I'm just curios is there any real test data available showing what IMD may be present at various supply voltages? I have heard many comments on the reflector over the years saying to keep the voltage high one member saying to keep it at 15V.The specs say 13.8 V nominal during TX. (11 V min, 15 V max) I would think that the transmit signal should be fairly clean within this range. At home its on a regulated supply 13.8 so NP but at the cottage where there is no utility power its on a battery with 6 and 10ga wiring all using solar charge. At night I will see voltages drop to about 12V after operating with lighting from the same battery for a while usually about 1:00 am in a contest. this is when I go off the air and to bed, as this is typically about when the battery reaches a 40-50% charge and I don't like to go below this. is operating approaching 12 volts (transmit) really an issue?

Re: [Elecraft] K3 13.8 VDC power
David, I think the answer to your question is a matter of degree. I do not have any specific test data on the IMD increase as the DC voltage is reduced, but it is a fact that the IMD with 'nominal 12 volt' transceivers will worsen as the voltage drops. The fact that the K3 IMD is better than most other transceivers also says that the IMD as the voltage goes down is better on the K3 than others. If you are concerned about it, I suggest you reduce the power to something like 75 or 80 watts when your power source voltage decreases. The difference between that power and 100 watts is likely not to be noticed by the receiving stations. 73, Don W3FPR On 12/22/2014 5:50 PM, david Moes wrote: I'm just curios is there any real test data available showing what IMD may be present at various supply voltages?

Hear lately it will work for a little bit then quit and I'll have to plug a phone plug back in and remove it again for the audio to return to the k3 speaker.

Re: [Elecraft] KX3 CW Weighting
Dennis - Thanks for the post. I’ve had a K3 for about five years and have really liked the feel/sound of it’s keying. Got a KX3 about a year ago and immediately noticed that is just didn’t sound the same as big brother. Not bad, but just not the same. I pretty much ignored it, as it wan’t really troubling me. But when I saw your post, I thought I’d see if that makes a difference for me. One word: WOW! I dropped my setting down to 1.05 as you suggested and now, on my KX3, it is perfect - for me, anyway. And the spacing/weight seems (to me) to be exactly like what big brother produces. Thanks!

Doing so, I discovered the CW weighting was set heavy by my ears (1.25), quite a bit different than what the CW sidetone represented, and possibly contributing to the readability report. I reset the weighting to 1.05 and the CW output now sounds exactly like the sidetone spacing. For those KX3 drivers out there, you may want to either listen to your transmitted signal, or simply trust my assessment and set menu CW WGHT to 1.05.

Re: [Elecraft] [K3] Remote Rig number difference?
Hi Larry, I thought I explained it before, but I will make another attempt ;-) RRC-1258MkIIs: This is the set that does the actual *remote control*. It provides all audio using the SIP protocol, rig control through CAT, CW support (including paddle), some limited relays and a virtual COM port (two if you don't need CAT), etc. See http://www.remoterig.com/wp/?page_id=1051 Webswitch 1216H or RC-1216H: These are web controlled *RELAYS*. The H version is an all rounder that can be used for rotor control, relays to control devices, temperature measurement, etc. It has no audio, CW, or other rig control functionality, it is purely for device control using relays. See: http://www.remoterig.com/wp/?page_id=166 The RC versions are more specialized to control devices, i.e. Acom 2000a, SPE Expert 1K-FA, KPA500, SteppIR and rotors.

Re: [Elecraft] 9M6XRO with my K2/10
Thanks for the replies you guys. I'd always heard about QRP guys busting pileups, and having done it once, I've got a lot more confidence for doing it again.

[Elecraft] cw id on SSB not working now.
I had set up my M1 to id in CW when I was rag chewing on my local freq. I do not know what changed but I can not get it to send my call in CW while in SSB mode anymore. CW Weight tapped 1 and got +cw used the K3 utility to set in my call sign under bank 1 M1. I push the m1 button now and it switches to transmit but does not send my call. Does anyone know what I might not have set right.

Re: [Elecraft] K3 13.8 VDC power
Well, more good information. Maybe I stand corrected. It's been nearly 4 years since I have read the manual, and my memory may have read more into the statements than it should have. I refer to page 13, right hand column, halfway down, entitled POWER. There is a note that reads To ensure correct save of operating parameters, turn the K3 off /before/ turning the power supply off. When I read that, I thought about the short duration power failures we experience. Page 44 touches on updating the nonvolatile memory correctly before shut-down either by the power switch, or in this case a 'PS0;' command via the RS232 interface. As you saw, there was a reply from a contester who had several power outages with multiple K3's without any troubles. That was good to learn of. I thought If I only use the battery for backup to shutdown, there should be a minimum of charging. I have been using a UPS on the AC supply, but I trust a float battery I can test on the DC. I may abandon the whole idea and stay with the UPS. Sometimes rejection is a good thing. Note: As I learn more about this radio, I appreciate the thought that went into it's design. Thanks for the posts, and the bandwidth.

Re: [Elecraft] Elecraft KX3 IQ out and spectral display pograms
Ok. This issue has been resolved. First I want to send a huge Thanks to K9YC for his body of work on RFI, and bonding , as well as W3FPR for setting me straight where I should be reading on the pan adapter and soundcard isses. I spent some quality time, along with an offline email (thanks Jim) and ended up bonding all equipment, laptop, KX3, basically any chassis. Since this is an expedition kit, I took his advice and built pigtails with power pole connectors connected to each chassis in the setup. This allows quick assembly and breakdown of the bonding system. After doing this First result.. all audible rfi noise in headphones.. gone. Voltage between devices seems to have been balanced. Spot on Jim. This was great, and it gets better. The noise I was seeing on waterfalls seems to be nastiness coming from the USB system on the laptop. I did some snooping with an HT to narrow this down. I applied a ferrite choke onto the USB cable along with ensuring a very secure connection to the USB port.. fired up the system and bingo.. 98% of the displayed noise on the waterfall is gone. (I am not sure if the Choke worked or if it was a loose connection, or both). Lessons learned.. 1. Read the Elecraft Manual. Carefully. 2. Read K9YC presentation and data Carefully. Raise your hands and say.. You are the go to man for this Reverend Jim! 3. Read telepost soundcard page. Read it again. Thanks again Don.. They have really added a lot of info since the last time I looked there. 4. Reach out to the authors as needed to reassure yourself what you read is true :-). (I guess it's a ham thing.. or maybe an N6WM thing hi hi) Net result (with all these little challenges solved) is I have the best sounding fully functional compact expedition/portable contestpedition setup that can fit in a pelican case(in my opinion.) Consists of KX3/KXPA100 Thinkpad notebook, mini speakers, small power supply, Xonar sound card, footswitch(tested and working) , headphones(CM500 tx audio dialed in), budipole and battery for the really remote stuff. With the IQ out into the Xonar , I have skimmer, N1MM Plus, and even power SDR running in a stable state giving a full waterfall display of my choosing. In fact I have them running all simultaneously. The entire setup works, and works well. Now I can pack all this stuff up and get back to planning its first travel date, and using my K3/0 connected to my not on expedition K-line at the hilltop station. Thanks K9YC and everyone else who responded.. this was a fun project... and of course keep cranking out these super cool products Eric and Wayne! ~Chris N6WM __ 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

It's hard to find the IMD -- there's some, but it's WAY down. 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
