Re: [Elecraft] KPA500 Proper Transformer Tap setting
Harry, You did get the official answer from Jack Brindle. He did some of the design of the KPA500. Yes, keyup - less than 85 volts.

[Elecraft] Best Heil Element for K3
I have a new Heil ProSet 7 with the regular HC-7 element. A friend of mine told me that that is the wrong element and that I should have gotten the IC electret element. In fact, he said that Elecraft recommends the IC element for the K3. Is this true? What has been anyone's experience with the IC element and the K3?

Re: [Elecraft] Best Heil Element for K3
Dave, Since you have the K3, your microphone should be fine - just turn bias OFF. The K3 has adequate mic gain range to handle most any microphone. I believe the HC-7 element has relatively low output, so you may have to use the High mic gain range. Your friend may be remembering the K2 which had limited microphone gain and did not do well with low output dynamic microphones. 73, Don W3FPR On 3/22/2015 8:48 PM, dave via Elecraft wrote: I have a new Heil ProSet 7 with the regular HC-7 element.

The one that keeps the no-load HV in spec and gives you the best performance. If that is the Red tap, then use that one. The two sentences are not in conflict. You should expect a major drop in HV on key-down due to losses in the power supply. This includes the components in the KPA500 (transformer, etc), the power cord, plug, wall outlet and wiring all the way to the main pole transformer. You can’t do much about most of this, but making sure the power cord can handle the current without overheating is a great idea. Of course this problem is worse with a 120V supply than 240V since the current is proportionately higher. So, again, if the red tap gives you better output and keeps the HV within the 85V spec under no-load conditions, use it. Make sure it meets both conditions, though. 73, Jack B, W6FB Elecraft Engineering On Mar 22, 2015, at 1:10 PM, Harry Yingst hlyin...@yahoo.com wrote: My line voltage is 239 (which calls for the yellow tap) but on Key down it sags to 59v With the Red Tap it only sags to about 66v (80.7 no key) So The proper tap would be?

Of course this problem is worse with a 120V supply than 240V since the current is proportionately higher. IF the wiring between the breaker panel and the outlet is under your control, it is a very good move to use bigger copper for that run. #14 is minimum for a 15A circuit, #12 for a 20A circuit, but going up to #`10 will reduce the IR drop under load. When doing the calcs, remember that the line current is NOT a sine wave, but rather pulses centered around the peaks of the waveform to recharge the input filter caps. That means that the voltage drop will be greater than if it were a sine wave. I have 240VAC in the shack to run my big tube amps, so I also run my KPA500 from 240V. 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] Anyone using a DXE NCC-1 with K3?
Am contemplating a purchase of a DXE NCC-1 receiving antenna/noise phasing unit very soon (tomorrow, actually---so I will have it in time for the WPX next weekend) for use with my K3/P3/KPA500 and was wondering if anyone else in the group uses one and how they have it configured. Apparently I will either need to run it via my RX antenna jack or else with a sequencing unit (or RTR-1A controller that DXE also sells) if I want to run it inline with my main antennas. My main usage will be for the reduction of RFI that I am often subject to here in our condo complex (plasma or LCD TVs, wall warts and other electronic RF garbage producers nearby). I currently use an old JPS ANC-4 with its attached noise receiving whip that works fairly well---but could still be much better. (I don't plan to buy the active antennas that DXE also sells with or without the NCC-1; at least not for any foreseeable future). I also use my Elecraft PR6 6M preamp affixed via the XVTR or RX antenna BNC jacks and am wondering if I can run the NCC-1 through it with or without the PR6 being on (I have it wired so that the PR6 activates only when I am on 6M, IIRC)---but I am getting older these days and am more easily confused/dyslexic when it comes to IN/OUT jacks than I used to. Will it be fairly easy to run both together or will it require removing the PR6 if I want to run the NCC-1 through the RX ports? Any user comments or thoughts on the subject will be appreciated; I have seen a few YouTube videos on the NCC-1 and it looks like it can be very effective on QRN coming from one particular source (like my ANC-4 but even noticeably better). It certainly will be fun to see the noise disappear or fall dramatically on my P3, too! 73, Jeff, NH7RO K3/P3/KPA500 __ 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
[Elecraft] OT Mirage D1010 432mHz Amplifier
I apologize for an off-topic posting. I’m trying to find a schematic diagram and board layout for the Mirage D10210 432 mHz amplifier. I just bought one on eBay. Although it generates power into a dummy load, I think something’s wrong with it because it has no idle current. The amp is supposed to be biased for SSB but doesn’t seem to be. There are three ‘thumb wheel” pots on the board, two of which appear to possibly be bias current settings for he pre amp and amp. However, tuning them does nothing to change the amp’s total current draw (which is 30 MA, presumably for the Power On LED). thanks in advance; please reply off the list. lew Lew Phelps N6LEW Pasadena, CA DM04wd Elecraft K3-10 / KXV144 / XV432 Yaesu FT-7800 l...@n6lew.us www.n6lew.us Sent from my Mac Pro 256-Array Supercomputer (9.42 teraflops) __ 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] Best earbuds for KX1?
My father was a metallurgist and a championship target shooter. He had four different ear muffs for work and for shooting. They varied in the frequencies they would cut out. One set was used for blocking high pitched sounds due to grinding or one of his high velocity furnaces. He built many types of furnaces during his metallurgical research. Kevin.

Re: [Elecraft] Best earbuds for KX1?
Jay : This topic comes up once in a while … the best I have found are Koss “The Plug” Originals. These are very sensitive, which you need for the KX1, especially on 20m where the rigs’ RX sensitivity is lower. They also fit quite snugly, blocking out external noise. Whatever you buy … you want something that is rated at least 100 dB SPL/1mW sensitivity otherwise you will probably find the volume a bit too low on the KX1. These Koss earbuds are rated at 112 dB SPL/1mW. I purchased a couple of sets a long time ago and both are still working fine, so they are quite well made. You seem to be able to get them for around $10 / pair on Amazon : http://www.amazon.com/Koss-Plug-In-Ear-Headphones-Black/dp/B1P4XA Here is the Koss website entry for them : http://www.koss.com/en/products/headphones/earbuds/PLUG__Plug_In-Ear_Headphone Michael VE3WMB P.S. Bonus … they also come with different sized “cushions” so you can customize the fit for your ears. __ 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] KPA500 Proper Transformer Tap setting
One thing to remember is that the 240 volt power line is not constant voltage. Line voltage varies through the day depending on the overall power load seen by the electric company in your area. So while you may measure 239v now, it may droop or go higher as the overall load varies during the day. That makes it difficult for us to give an absolute value for the tap setting, and also makes it difficult for you to say that any one is always the best. Try one for now, and if it works out in the long run, then keep it! If you start seeing HV high voltage faults, then drop back to a lower voltage tap. As K9YC says, you can help by using the biggest wires you can find, especially for the power cable from the wall to the KPA500. This is especially important at 110V, but applies to 220V as well. And, for the record, the KPA500 HV fault is at 90 volts.

Re: [Elecraft] Best Heil Element for K3
Elecraft does sell a Heil Proset-K2 with the iC element. However, like any electret element it requires some TX EQ to be effective. The low end typically needs to be rolled off [-6 dB @ 200 Hz, -16 @ 100 and 50 Hz] to prevent rumble and wasted transmit power while the high end generally needs boost [+3 dB @ 1600, +5 dB at 2400, +6 dB at 3200] for articulation (as paging and PA system designers have known for decades). The HC7 has that contour already 'built-in' - the only thing needed is to disable the bias (DC voltage) on the mic jacks and select a little higher gain for the mic preamp (an electret has about 26 dB more output than a dynamic mic like the HC7). 73, ...

Re: [Elecraft] Best Heil Element for K3
Hi Dave, I got the same headset, and it would not work with the remote setup using the K3/0 mini to connect to a remote K3 with the RemoteRig system linking them. There was way too little mike power to move the needle. I then bought the Pro-Set that Elecraft sells, and it came with the little iC sticker indicating the Icom version. I sent my Pro7 back for a swap of elements to the iC electret, and everything worked fine. BTW, the Elecraft hand mike (MH2) also worked fine, and one of the guys at Elecraft told me it had an electret element. That said, I am certain the same problem did not occur when using the mike with the K3 itself. Plenty of gain with either version mike. 73 de Brian W3BW Brian F. Wruble, C.F.A.

Re: [Elecraft] K3 Sync AM receive freq. response
That's something I plan to experiment with ... but the 13 KHz filter is considerably wider than the 5 KHz DSP bandwidth in sync mode. For what it's worth, the identical effect occurs with the 6 and 2.8 KHz filters also.

The 13 KHz filter has more than adequate bandwidth for Sync (USB/LSB) AM. Even if it is off by as much as 2 KHz the bandwidth is enough to pass the full 4.5 KHz recovered bandwidth. The upper/lower edge is determined by the DSP characteristic, not the crystal filter bandwidth. Looking at an audio spectrum display with hold it's fairly clear to see there is roughly a 50 Hz difference in the lower frequency limit between LSB and USB in Sync detection while by ear there is a qualitative difference (more open) high end in USB. There is no perceptible difference when moving the FM filter offset from limit to limit. The difference persists even when forcing use of the 2.8 KHz crystal filter. It's purely an issue in the DSP function. 73, ...

Re: [Elecraft] KPA500 Proper Transformer Tap setting
I originally had mine set up for 240 because I thought it would operate more efficiently that way. 6M kept giving me faults and for some reason reconfiguring the amp for 120 volt operation seems to have stopped the faults. Mike KI0HA Thank you, That was how it seemed I just wanted to double check. That amp seems a bit happier on 240 than 120. If one has 240 available, an amp should always be run on 240 rather than 120. __ 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

Yes he gave the official answer. I figured that was the case, but admittedly this is the first time for me with a Solid State Amp so I wanted to ensure I was reading it right. What a nice chance from Tubes, and with the KAT500 it's like having a 500 watt radio.

Re: [Elecraft] Best earbuds?
Good suggestions, all. Like Jim Brown, I come from the audio industry, and the best In Ear Monitors (IEMs) I have are the Etymotic ER4s. I have owned a pair for twenty years, and still love them. They come with the 3-flange ear tips, but are best used with deep canal ear molds. These are individually molded at an audiologists, and the resulting fit can offer up to 35dB or more broadband attenuation to ambient noise. This allows the use of moderate drive power and by suppressing ambient acoustic noise really opens up the noise floor for analysis. For those who desire a more modest model, the next best alternative IEM I have found is the Audio Technica ATH-ANC23, which has Active Noise Cancellation (ANC) which works well. Although the amount of noise cancellation they offer is less than some Bose models, I find the audio quality to be superior to the Bose. I have used these in many multi-op contests where an SSB op was yelling AGAIN, AGAIN??? for what seemed like hours next to me while I tried to copy weak CW, and the ANC really helped! For the record, the very best audio quality I have heard from an IEM comes from the Sennheiser IE800s. They rival the best over-ear models and approach the quality of the Stax electrostatics at lower volumes. Not the most comfortable IEMs, and the sound is greatly affected by proper fitting to the ear canal, but once you get it right, man do they sound great!
