Re: [Elecraft] K3-Front panel shut down question.
No problem to shutdown K3 from the PS during normal operation, except that the last used frequency and controls wouldn't be memorized. No chance for any hardware or software trouble. The UPS or battery only would allow you to finish off the QSO, no other benefits. Even the interruption during FW update is not deadly for K3.

Re: [Elecraft] K3-Front panel shut down question.
David, I would switch my computer off at the supply only if it, the OS and the other software were designed in such way, that the hard switch off wouldn't cause any harm. We all know that this is not the case with the PC and Windows. K3 however is different. Most of the modern house appliances also have embedded computers and they usually don't fear of a PS interruption too. 73 Val LZ1VB I would not have thought that this is recommended, Val.

[Elecraft] Changing DATA-A modes with Memory Editor
I have a problem Houston! I've tried to program my memory channels for DATA-A mode to reflect a change in DATA MD, and its not taking it. I re-programmed the memory in question to CW mode to clear the memory mode and uploaded it to the K3 successfully,. Next I selected the memory on the radio using MV button and rotating VFO-A. Then I changed mode from CW to DATA-A and DATA MD to the sub mode I want to program. Then I change the mode in Editor from CW to DATA-A and select that memory ID and Send Selected. DATA-A is saved but not the DATA-MD that I wanted. Every time I send from the Editor is puts AFSK A on LSB with 45bps bw. The only DATA mode I want to use is DATA-A USB. The editor is writing to the K3 because I see the activity deleting and writing. It is connected with the same COM$ that I use for the K3 Utility program which runs properly. I even upgraded Editor to vers. 1.0.203.0 which is the current version available on the Elecraft website. So what is the secret handshake?

Re: [Elecraft] Changing DATA-A modes with Memory Editor
Ed, Can I suggest a work-around while you are waiting for the K3 memory editor to be changed. Note that what I see in the K3 Frequency Memory Editor is just a selection of DATA mode - I do not see the selection of the data sub-modes nor the selection of which sideband is to be used in DATA mode. Store all your memories with the K3 Memory Editor, then back at the K3, retrieve the DATA mode memories one by one, change the DATA MD and store them back using the K3 buttons. I have entered memories in my K3 manually and they do stay in the correct DATA-A submode. 73, Don W3FPR On 8/18/2011 5:03 AM, Edward R. Cole wrote: I have a problem Houston!

Re: [Elecraft] K3-Front panel shut down question.
The danger with the K3 seems to be if power is removed while it's actively writing new data to memory. Early in the K3 program several people who switched power off at the supply quickly reported finding the firmware corrupted in various ways upon restoring power because of that. Certainly no physical damage was done, but it is rather inconvenient to reload all the firmware. 73, Ron AC7AC __ 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] K2 volume
Hi, I’m still trying to pin down the cause of the low-ish volume of my K2 (s/n 6905), which seems to be something occasionally reported with this transceiver. Dave White, VE6DRW, recently sent me the documentation of the AGC mod to try. (Thanks Dave for digging it out for me – I tried to thank you via email, but they kept bouncing.) According to Dave the mod usually fixes the problem, but this doesn't explain why sometimes it's necessary and not others. I know the K2 does not have a huge amount of audio gain (for reduced battery consumption during portable operation), nevertheless, most users say it is more than adequate in a normal environment. I always have the RF gain set to max and need AF set to max, or near max. I am listening in a very quiet shack. (And last time my hearing was tested about two years ago it was normal.) I have a separate active receive antenna, but this only confirms the situation is not due to a poor antenna. (The main antenna is 120 ft random wire at 40 ft high via an ATU.) The audio amp in my K2 is working properly as far as I can tell by tests carried out using the side tone set to max and measuring the peak-to-peak voltage across the speaker (1.7 V p-p) which is about right by all accounts. The speaker in not faulty and I have used various makes/types of headphones all with similar results. The AGC voltage is set to 3.75 volts and with no antenna connected there is no difference in noise between AGC ‘on’ and ‘off’. L34 is peaked and the alignment procedures were followed. Reading through the threads again it seems there is a real ‘issue’ here, not a variation in expectation from owner to owner, but ‘something’ that is going on. What seems odd to me is that most owners say volume is fine, so there genuinely appears to be a variation in audio volume - though not necessarily sensitivity as far as I can tell. But what is causing it? I am considering building the Elecraft SP2 speaker, but I don’t feel this should be necessary given the complexity and design of the K2; and it's not really getting to the cause. So… is this a consequence of component tolerances or just incorrect/sub-optimal alignment?

There are some number of things you do not mention. 1) is the S-meter showing AGC in action when you are having the low volume? 2) are you using the internal speaker in the top cover or are you using an external speaker? 2a) if external, what speaker is it, brand and model number, what is its impedance, and is it amplified? 2b) if internal in the top cover, does its sound seem constricted or narrow banded, or does it seem full ranged?

Re: [Elecraft] K2 volume
Hi Ian, Do you have access to a RF signal generator, or can you build the crystal oscillator source shown in the troubleshooting section of the K2 manual? I've found the receiver signal tracing protocol described there to be helpful. The RF probe supplied with the K2 is useful if you have a good high input resistance DMM. There are several possible sources of unintended signal attenuation along the path from antenna connector to audio output, so more experiments will be required to deduce the section(s) in which problems may exist. You mentioned using an ATU with your longwire antenna -- if it's the KAT2 inside the K2, did you check to be sure that your antenna port selection in the menu is for the connector to which the antenna is actually connected? Do you notice a difference in audio signal levels on different bands or is the audio output uniformly low on all bands? 73, Mike, K8CN -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-volume-tp6699863p6700080.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] K3-Front panel shut down question.
But first, before plugging the K3 DC supply into any UPS, make sure the UPS has true Sine Wave output and is not Pseudo Sine Wave when on battery power (or when creating AC from its built in voltage converter circuitry). Your 12v supply's capacitors may clean up a lot of the hash and harmonics created by Pseudo Sine Wave UPS's, then again, they may not. Just a thought...

Re: [Elecraft] K3-Front panel shut down question.
I'll repeat W2CS suggestion, get a UPS, then plug the K3's power supply into the UPS. Since you are trying only to allow yourself to shut down cleanly, you can get the smallest capacity, and therefore the cheapest version. It will handle the K3's RX current for quite a while, even with a small UPS. Some of the commentary seems to be about creating a full run floating battery alternate supply. If you want that, it's one approach, but if all you want is orderly shut down, you hardly need go that far. If you already have a UPS for your PC, plug the K3's power supply into that UPS. When you are operating with AC the extra drain makes no difference to the UPS. When the power goes down, cease transmitting quickly and you will be fine. The K3 in RX only adds about 20 watts to the load on the AC. 73, Guy.

Re: [Elecraft] K3-Front panel shut down question.
Not necessarily true -- I had an APC UPS that created continuous 60Hz-flavored hash on all ham bands (at least up to 21 MHz), S6-S7 level, whether commercial power was present or not. I wrote to APC and they said their equipment met FCC regulations with regard to spurious emissions, and very kindly sent me a deluxe noise-and-surge suppression outlet strip. It made no impression whatsoever on the noise, nor did one clamp-on ferrite bead (all I had that would fit the cord at the time) on the AC supply cord next to the unit make any difference. Perhaps if I had had enough beads to put a couple on every cord plugged into the UPS as well, it would have helped. I just got a Tripp Lite UPS of the same size and had no further trouble.

Re: [Elecraft] K3-Front panel shut down question.
I've heard similar things about APC UPS's. However I now have 5 of them sprinkled throughout the house and the modern versions (c last 3 yrs) are clean. I also have a cyberpower UPS that claims sine wave output that is clean. I needed the latter for one computer that would not accept the pseudo sine wave output of the APCs. All clean whether on commercial power or supplying power. YMMV of course. But if all he wishes to do is not yank the power out from under the K3 so it can be shut down cleanly, I agree with K2AV. Plug it into your computer's UPS as stated. That's exactly what I do with mine. And my UPS is hefty enough to run the K3 barefoot for 10-15 minutes. Most power outages are far shorter than that here in rural upstate NY. 73/Gary W2CS -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft- boun...@mailman.qth.net] On Behalf Of Van W1WCG Sent: Thursday, August 18, 2011 7:38 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3-Front panel shut down question. Not necessarily true -- I had an APC UPS that created continuous 60Hz-flavored hash on all ham bands (at least up to 21 MHz), S6-S7 level, whether commercial power was present or not. I wrote to APC and they said their equipment met FCC regulations with regard to spurious emissions, and very kindly sent me a deluxe noise-and-surge suppression outlet strip. It made no impression whatsoever on the noise, nor did one clamp-on ferrite bead (all I had that would fit the cord at the time) on the AC supply cord next to the unit make any difference. Perhaps if I had had enough beads to put a couple on every cord plugged into the UPS as well, it would have helped. I just got a Tripp Lite UPS of the same size and had no further trouble.

Under normal conditions with AC present, the inverter is not active. It was not the initial question, but -- if you want to keep transmitting after an outage, you will have to implement the large battery solutions that have been mentioned. 73, Don W3FPR On 8/18/2011 2:22 PM, Guy Olinger K2AV wrote: I'll repeat W2CS suggestion, get a UPS, then plug the K3's power supply into the UPS. Since you are trying only to allow yourself to shut down cleanly, you can get the smallest capacity, and therefore the cheapest version. It will handle the K3's RX current for quite a while, even with a small UPS. Some of the commentary seems to be about creating a full run floating battery alternate supply. If you want that, it's one approach, but if all you want is orderly shut down, you hardly need go that far. If you already have a UPS for your PC, plug the K3's power supply into that UPS. When you are operating with AC the extra drain makes no difference to the UPS. When the power goes down, cease transmitting quickly and you will be fine. The K3 in RX only adds about 20 watts to the load on the AC. 73, Guy.

Re: [Elecraft] K3-Front panel shut down question.
harbor freight has a 10 bux float charger for 12 v batteries I believe it will start at 2 amp then trickle back to a hold charge usually have good luck with H F Bob K3DJC On Thu, 18 Aug 2011 16:30:05 -0700 Jim Brown j...@audiosystemsgroup.com writes: On 8/18/2011 11:22 AM, Guy Olinger K2AV wrote: Some of the commentary seems to be about creating a full run floating battery alternate supply. If you want that, it's one approach, but if all you want is orderly shut down, you hardly need go that far. Actually, this is quite easy and inexpensive to do. I use one of the biggest 12V batteries that Costco sells (about $75) and float charge it with a little 10A switching power supply that I bought for $10 at a hamfest. I've adjusted the float voltage to 14V, and the battery lasts for at least 3 years. The key is to carefully set the float voltage so that it doesn't overcharge the battery. 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 Penny Stock Jumping 3000% Sign up to the #1 voted penny stock newsletter for free today! http://thirdpartyoffers.juno.com/TGL3141/4e4db1a2b213458636m03vuc __ 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] KSB2 Resistor Packs
Brendon, I would wager that you purchased the KSB2 about 3 months ago. There was a short period of time when only 1 of those R-Paks was placed in the bag. That problem has been corrected by the kiting quality control. I spotted the problem when I found 2 kits with only one 2.7k R-Pak - one kit could be a one-off packing error, but with two kits, it looked more like a bigger problem. Val checked stock and got things fixed. As I recall, that was about 3 months ago, but I can't recall the exact timing. Contact pa...@elecraft.com and ask for the 2nd 2.7k R-Pak, it should be sent to you promptly. 73, Don W3FPR On 8/18/2011 9:37 PM, vk8fqrp wrote: Good Day All, Going through the inventory for the KSB2.

I regard these frequently received emails inviting me to join this or that social networking group as nothing more than spam. If I want to join a networking group, I'll join it.

[Elecraft] Hi Cur
Hello to all, Need some help. After finishing up on 80 cw last night I moved up to 20, hit the auto tuner for the beam and received HI CUR. And this only ocurred on 20 even with a Dummy Load attached. Msg seemed to go away once I reduced the wattage down around 60 watts.

Re: [Elecraft] Hi Cur
Looks for an RFI problem that only occurs on 20m. Or a grounding problem, maybe with a long leg like 5m or so. Nice resonant section there. matt W6NIA On Fri, 19 Aug 2011 00:31:53 -0400, you wrote: Hello to all, Need some help.
