Re: [Elecraft] K3 Power Supply
I've never heard of a 1225 but have a 1223 and a 1235. I have both and they have been running strong 27/7 for just about 7 years never a single problem. But I do have proper voltage to run them also. QST did find them a best buy and not long ago either I can attest to that also and no noise. I seems like you must have some sort of problem on your end as I know a lot of people with and no problems with them either. In fact I spoke to a dealer and he told me they have the least amount of returns on them than any other power supply in its class. -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Matt Zilmer Sent: Wednesday, June 12, 2013 9:55 PM To: Randy Cook Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Power Supply Well, shucks.

Re: [Elecraft] USB Sound Card for Win7
Dick, You are almost there. It appears you got through steps 1 and 2, but you also need to do steps 3, 4,and 5 below: 1. Right click on the speaker icon on the lower right of the screen and select Playback Devices. 2. The Sound window will open. Be sure the Playback tab is selected. This is where you can select the default device. More on that below. 3. Right click on Speakers iMac USB Audio System and select Properties in the dropdown menu. 4. The Speaker Properties window will open, select the Levels tab in that window. 5. Be sure the Speakers slider is set to something greater than zero, and be sure the little speaker icon is not muted. You can leave this window open while you try to play a file; however, be sure to click on OK once the volume is set correctly. Be sure you have the headphones plugged into the Out jack of the iMac. Of course, I never make mistakes like that. ;-) If you are simply playing a file back, you must have the iMac selected as the default device in the Sound window, item 2 above. That tells your PC to send the digital sound (music) to that device, unless you tell a specific program otherwise. You do not need for it to be the default device if you are setting it up to work with a program such as FLDIGI. You will tell that program to send data to that device. In fact, you probably don't want it to be the default device so you can prevent Windows from sending your music, and every other beep and blurp that Windows makes, out over the air! That is one big advantage of using a separate soundcard for digital modes. Hope this helps.

Re: [Elecraft] Power Supplies for K3
I currently use an Astron RS-35M in my home shack. Yes it's big and hot but it works well, puts out no RF hash and is easy to repair if something goes wrong with it. I also have an MFJ-4125 switcher for backup that I've had for years and it works great with no RF hash. It does have a noisy fan but there are mods to fix that. I almost always wear headphones so the fan has never bothered me. I tried a JetStream switcher from CheapHam last year but it put S9+ out all over the HF bands so back it went! I also have a Pyramid 35 amp linear supply I use at our lake cabin but it has needed repair several times so I would advise staying away from that brand. 73 Bill NZ0T -- View this message in context: http://elecraft.365791.n2.nabble.com/Power-Supplies-for-K3-tp7575122p7575196.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] YEEE HAA!
As a former railroad company officer, I can tell you that UPS uses the nation's rail system very heavily for piggyback (trailer on flat car, or TOFC) shipments that are longer than one or two day's run in a truck. The "break-even" distance (rail and truck costs equal) varies depending on fuel costs and specific locale, but in general, if it's traveling more than 1,000 miles it will do most of that journey by rail. The major railroads all run UPS-only trains, and they have about the highest priority of any traffic on the line, equal priority for use of the main line with Amtrak, and sometimes higher.

I still don't understand why it can't be included in the firmware as an option even if you key the TX with a footswitch, but that is the way it is. The rig can not tell if you want to transmit SSB or CW if you assert PTT before the key closes and because of settling time for the various oscillators/synthesizers/offsets can't change from SSB to CW while in transmit. If one were to change from SSB to CW with every key closure (which is what would happen if one permitted CW with PTT in SSB, the CW would be very "whoopy". 73, ...

Re: [Elecraft] USB Sound Card for Win7
Thanks to those who answered my post about using iMic on Win7. First let me say I tried all the things suggested with no luck. I never found anything muted or disabled. At first, nothing, then I could play sounds, but no music. It seemed that it began working after I used Quickmix to load iMic. (Actually, it showed USB audio device.) **I noticed I now had a volume slider for Windows Media Player which I did not have before. I now could play music. The slider can be seen by right clicking the speaker icon, and then selecting 'open volume mixer'. I had trouble using Quickmix on Win7 when I first tried it several months ago. I wish I could remember what the fix was. (Maybe later.) Quickmix has been working fine and is a handy utility. Thanks for your help.

It appears you got through steps 1 and 2, but you also need to do steps 3, 4,and 5 below: 1. Right click on the speaker icon on the lower right of the screen and select Playback Devices. 2. The Sound window will open. Be sure the Playback tab is selected. This is where you can select the default device. More on that below. 3. Right click on Speakers iMac USB Audio System and select Properties in the dropdown menu. 4. The Speaker Properties window will open, select the Levels tab in that window. 5. Be sure the Speakers slider is set to something greater than zero, and be sure the little speaker icon is not muted. You can leave this window open while you try to play a file; however, be sure to click on OK once the volume is set correctly. Be sure you have the headphones plugged into the Out jack of the iMac. Of course, I never make mistakes like that. ;-) If you are simply playing a file back, you must have the iMac selected as the default device in the Sound window, item 2 above. That tells your PC to send the digital sound (music) to that device, unless you tell a specific program otherwise. You do not need for it to be the default device if you are setting it up to work with a program such as FLDIGI. You will tell that program to send data to that device. In fact, you probably don't want it to be the default device so you can prevent Windows from sending your music, and every other beep and blurp that Windows makes, out over the air! That is one big advantage of using a separate soundcard for digital modes. Hope this helps.

Re: [Elecraft] Accessory Line Protection
Mike, If you have the 74154 inputs connected to the K3 band data outputs, nothing more should be required. The 74154 should adequately isolate the inputs from whatever you have connected to the output side of the decoder IC. I don't even know if the capacitors are required (or desirable), although since the band data outputs are not dynamically changing, they should make no difference. If you have anything else connected to the K3 band data outputs (in parallel with the 74154), then that may be a different consideration, but you did not mention anything of that nature. The KPA500 should not cause a problem. If you have trouble with the KPA500 band selection, try removing the capacitors and see if that cures the problem. 73. Don W3FPR On 6/12/2013 7:27 PM, w0ih wrote: Well, I got a bit lazy and tired of changing antennas to my K3 so I built a system to automatically change antennas as I switch bands. What I'm trying to accomplish is to be able to control my station remotely over the internet (I use TeamView which includes audio). I'm driving a 160 meter dipole, 80 meter dipole (my own design, tunes from 3.5 to 4.0), 60 m dipole, 40 meter tap off the boom of my beam, TH11DX beam and a 6m vertical (2m and 440 as well). Basically what I did was to build a remote antenna switch (from an April 2005 QST article) built from a FarCircuits.com kit (circuit board and relays, ~$40) as the remote switch. I have a single coax coming the last 50 feet from the base of my tower up to the shack. This remote switch (grounds the antennas when not in use) is driven by a circuit that I build using a VERY old chip from my junk box, a 74154 BCD to decimal line output chip (decodes the K3 Accessory Band outputs 0-3 to a 1 of 16 line output). I also have a manual setting that allows me to switch the antennas with a rotary switch - 1 to 6, so I can use it with my KX3 as well. So, my question, I have tapped off the Accessory output lines on the back of the K3 into the antenna controller to the 74154 chip. I have some .01 uf capacitors for filtering the lines. But my question is, do I need any other protection for the lines coming from the output of the K3 to my controller? The outputs of the 74154 drive a set of 6 5 volt relays which drive the lines (and LEDs) down to the remote antenna switch board. The cable from the K3 Accessory plug to the controller is shielded and grounded to the chassis. There are 6 lightning arrestors on each of the coax inputs (copper strapped together and ground to the base of the tower). The six control lines from the controller to the remote antenna switch are also shielded and grounded (12 volts to drive the relays). But am I missing anything in protecting the K3 lines to the controller? I've checked the schematic of the K3 but can't find much on the outputs for protection. Incidentally, I do also have a KPA500 that is also connected to the system Accessory output.

[Elecraft] Need a Fuse on the K3's Power Line?
I was just looking at my new K3's (#7489) power cable, and see that it is not protected by a fuse (although I think I saw an instruction to use an in-line fuse if I connect it to battery power). I see what looks like a 20a fuse (or breaker) on the back of my K3/100, although I believe I read that it draws 25a continuous duty. I was thinking of connecting my radio either directly to a 70a Astron p.s. (which will also handle my 50w 2m mobile rig and a variety of other smaller loads) or through a 25a fused receptacle on a RigRunner, itself connected to the Astron.

Re: [Elecraft] Need a Fuse on the K3's Power Line?
Yes, that is a circuit breaker on the K3 so a fuse probably is not necessary. Of course there would certainly be nothing wrong with using a fuse.

Re: [Elecraft] Need a Fuse on the K3's Power Line?
I believe that the circuit breaker only protects the KPA3. If you're running off battery, or other unprotected power-source, I think you would really want an external fuse (as close to the power source as possible, in case you get a short in the supply cable somehow). 73, ~iain / N6ML On Thu, Jun 13, 2013 at 6:06 PM, Michael Eberle wrote: > Yes, that is a circuit breaker on the K3 so a fuse probably is not > necessary.

Re: [Elecraft] Need a Fuse on the K3's Power Line?
There's also a separate 6A fuse protecting the rest of the K3. Anything in the power cable is strictly redundant.

Re: [Elecraft] Need a Fuse on the K3's Power Line?
Paul, An in-line fuse close to the power source is always a good safety precaution. You are protecting the wire against a fault as well as the equipment on the far end of that wire. A 12 gauge wire will safely handle 25 amps - but it will not safely handle the full 70 amp output of your wower supply without vaporizing and possibly spewing molten copper all over your hamshack, and can present a fire possibility. #10 wire can safely handle 40 amps, but again, not the full output of your 70 am supply. I encourage you to fuse near the power supply for the wire size that you use for connections from that supply. The rigrunner is a nice device allowing you to fuse the input for the wire size that you have connected to the supply and also fuse the branch circuits according to the needs of the devices being powered. I fuse #12 wire at 25 amps and #16 at 10 amps. #18 gets a 5 amp fuse. 73, Don W3FPR Fuse it according to the wire size.

Re: [Elecraft] Power Supplies for K3
I have 2 of the SS-30M and have never seen this problem (fan noise). They are very quiet whether the fan is running or not. I like the "M" version with meters. They are powering 3 radios including the K-3 and 2 brick amps. I find it helpful to have the ammeters. For example, this past weekend I had a feedline connector problem which resulted in the brick dropping power output. It was immediately apparent via the ammeter that there was a problem. The only issue I've had was a failed rocker switch which was easily replaced since it snapped in and the wiring used Faston terminals. The older one I've been running for 12 years now and going strong! 73, Josh W6XU On 6/13/2013 2:49 PM, Richard Fjeld wrote: People have mentioned the Astron SS-30A switcher. I have one and noticed when the fan came on, I could hear a high pitched squeal in the audio. Also on Tx. I read other reports of this. Some people put ferrites on the fan wires. If I remember correctly, I re-heated the solder joints on the fan wires. Problem solved. I like the supply because of it's small size and light weight. I use it when portable.

The 74154 should adequately isolate the inputs from whatever you have connected to the output side of the decoder IC. I don't even know if the capacitors are required (or desirable), although since the band data outputs are not dynamically changing, they should make no difference. If you have anything else connected to the K3 band data outputs (in parallel with the 74154), then that may be a different consideration, but you did not mention anything of that nature. The KPA500 should not cause a problem. If you have trouble with the KPA500 band selection, try removing the capacitors and see if that cures the problem. 73.

[Elecraft] Need a Fuse on the K3's Power Line?
If you do not have fast fuses in 12V DC wire you may end up with loose and broken PCB traces in RF board, also the connectors can be damaged. I bought a used K3 #6913, the seller said that he had messed the polarity with car battery. That caused a major circuit board problem in the trace that lead to KPA3 in RF board. The seller had fixed the problem temporarily but it really need better fixup to keep it working. He hadn't put fuses in the DC wires as the manual suggest, maybe he just trust the 20A circuit breaker of the KPA3. Obviously that is not adequate protection. Maybe also Elecraft engineers can do something to the reverse polarity protection to make it more robust, to my mind the protection is not adequate if it results loose PCB tracks, eventough support so claims. At least Elecraft should supply fast fuses in the 12V DC line to prevent other damages, maybe a humble manual note is not enough. Here is a picture of what is the result if you don't have the fuses in place. https://plus.google.com/photos/103676169039107946672/photo/5889028521722277378 73 de OH9VD/Jarmo __ 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: anyone using Sennheiser HMD 280 Pro?
good morning, since quite a long time I'm using the 'beyerdynamic DT234 pro' with my K3. It sounds good RX and TX wise and is quite comfortable for my needs. They are not cheap, but less expensive then the Sennheiser brand ones. I was following the Yamaha threads on this reflector for a long time, but didn't find a chance to buy one over here in Europe. I believe the Yamaha is sold as 'Koss SB40' in this part of the world. Some comparing between both brands made me believing that ... but I'm not sure about it. I bought one, used it but put it aside as my spare one. Anyhow, I own both now but stick with the beyerdynamic. The ear cushions (kind of velvet like surface) are much more comfortable for me and my ears ;-) than the leatherette like ones of the Koss. But YMMV.
