Re: [Elecraft] Older manual for XV432 transverter
Vic, No, this is a very early one. However, you could tell the reflector about your cure for self oscillation. There has been a very recent change in the power module which also cures not only the tendency for instability, but also is better for linear operation. The new power module is a Mitsubishi RA30H4047M1, Elecraft PN E600120. Apparently the manufacturer of the old power module changed it without notification and it is not as linear as the older versions. Anyone having trouble should change to the newer module. 73, Don W3FPR On 1/12/2014 2:31 AM, Vic Goncharsky wrote: I have assembled one last year, is that you're looking for?

[Elecraft] [K3] Sub RX and E-MU 0204
A few years back, I bought a CreativeLabs E-MU 0204 for SDR applications (i.e. SoftRock and Genesis G59). After buying a K3 and later a KX3, I no longer needed the soundcard for SDR so it sat in a file cabinet on and off for a couple of years. I have tried on and off to make the 0204 work well with different applications. I run Mac OS X 10.9.1 now so I am not as familiar (but I'm learning) with different applications as I once was with Windows. For a long time, I just ran with my old standby - a SignaLink USB. Now, I know what a lot of you will say - the K3 will accept a soundcard input directly from your computer and you are correct. The problem is that I hear way too many Windows sounds over the air. It is my firm opinion that a discrete soundcard for digital only operations is needed in the amateur's shack. Anyway, I ran with the SignaLink for years. It is very convenient in its operation with the ability to accept a multitude of transceivers for keying and input and output for sound. All of the controls are on the front of the SignaLink with the ability to adjust both TX and RX levels (and Delay although I've never found a use for that with my casual operations). The one major drawback (in my opinion) was the mono-only receive capability. Yesterday, I finally figured out how to make the E-MU 0204 work with my K3 and the ALC levels. In DATA A mode, the line input adjustment was not quite fine enough. Testing with RTTY, at about a line input level of 4, the ALC was three bars. At a line input level of 5, ALC was a solid five bars with *no* flickering of the fifth bar. Yes, you could say I'm anal about my TX drive, but as with Windows sounds being transmitted, there are way too many amateurs who overdrive their transmit audio. I wanted it to be correct and I finally figured out how to do it - the Audio Midi Setup. After playing around with different sound settings on the Mac and not being able to achieve what I wanted, I broke down and read the 0204 manual (imagine that!). The manual discusses using the Audio Midi Setup on the Mac OS. After fiddling with those settings for a bit, I finally got the K3 to transmit at four bars ALC with the fifth flickering. Now, I am a bit befuddled as to why PSK31 seems to transmit at a lower audio level. For PSK31, I have to fiddle a bit with the line input on the K3 and it's usually just a single digit of fiddling, so it's not a big deal. My only guess is that PSK31 has a lower audio transmit level than RTTY. The beauty of using the E-MU 0204 is with diversity receive, you can hear both receivers with the soundcard - the left channel is one receiver, the right channel is the other. You can do the same thing when a DX station is working split. As far as I know, that is *not* a capability which the SignaLink USB has. My digital software of choice is Fldigi; however, I do not believe it has a dual RX capability. There are other applications that do. For the Mac, there is cocoaModem. It does not have the number of modes available to it that Fldigi has, but it will allow you to operate the modes for which I see most contests / operating events. I have not yet tried the E-MU 0204 with my KX3 yet, but I am going to. I am hoping that the headphone output on the 0204 will allow me to monitor both transmit and receive audio. I miss that when using the KX3 on digital modes although I know there are ways to get it. I hope this is not too far off topic, but I thought I'd share what I found using the E-MU 0204 and the K3. 73, Joel - W4JBB __ 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] k3 doesn't toggle power level with kpa500
I recently had to take my K3 out of service while I waited for a new K3SYN board. Now that it is all back together the power level on the K3 will not toggle when the KPA500 is switched from standby to operate. Operate and Standby appear on the K3 LCD screen but the power level doesn't change when I switch the amp in. Everything is hooked up the way it's been for the past three years, only the K3AUX cable, power and RF in/out are connected on the KPA500.

Re: [Elecraft] KXPA100 Mobile Operations -- Power Output
I've started testing the KX3/KXPA100 mobile configuration, but don't have all the cabling in yet and it's not permanent. This KXPA100 has the ATU. Antennas are Hustler on a custom vehicle mount. The vehicle is a Honda Civic with a standard 12V electrical system. Not seeing any issues with this particular setup. Wiring to the KXPA100 is 8 AWG, with two transfers to APPs at a relay enclosure for power control in the trunk. The source is the Civic's battery. The KXPA is located in the trunk. With the engine running, I am getting 100W. During key down at full power, measured voltage at the amp is showing 12.2V or more (depends on whether the regulator decides it's battery charge time, I suspect). With the engine off, I get between 11.4 and 11.8V at the amp with power set at 60W or below. Ymmv, because it would depend on the battery's state of charge and any other loads on it. I've run the KXPA as high as 60W with battery-only, but I'm still in a test phase and waiting on cabling to arrive. 73, matt W6NIA On Sun, 12 Jan 2014 09:47:03 -0800, you wrote: Given the newness of the KXPA100 I am not sure if anyone has put it into a battery driven mobile operation yet.

Re: [Elecraft] K3 Power cal
Not enough info. Are you running an audio based mode? i.e. JT65? If so, then it is very likely that you are not setting the audio levels properly to drive the K3(s). If the audio level is not set properly, the K3 will try to increase system gain to reach the desired output, resulting in the symptom you report.

Re: [Elecraft] KXPA100 Mobile Operations -- Power Output
Thanks, Jim. Many of us will benefit from your thoughts. When the time comes to make a permanent installation with the KXPA100, I'll be sure and re-read your email. I already have the KX3 set up in the mobile. It is working fine, but antenna efficiency isn't very good with the Hustler type. The amp will give a good boost to output. Receiving is already pretty good due to the KX3's performance. 73, matt W6NIA On Sun, 12 Jan 2014 10:57:14 -0800, you wrote: On 1/12/2014 10:26 AM, Matt Zilmer wrote: Wiring to the KXPA100 is 8 AWG, with two transfers to APPs at a relay enclosure for power control in the trunk.

Re: [Elecraft] [K3] Sub RX and E-MU 0204
Joel, Having a emu 0202, I wondered what the 0204 differences would be. Looks to be an upgrade for win7. You can take the emu stereo output as IQ input to SDR sw. I do that for JT65B on 2m-eme. I cheat a little by connecting the K3 line-in to the emu Headphone jack which has a manual level control (so I do not have to mess with sw level bar adjustments in the computer), Receive audio levels are set with the L and R Mic control. I usually do not change the K3 Line-in level from 10. I think there is a place where you can disable soundcard tones in your computer OS, so those beeps and boops will not be transmitted. My computer's original internal soundcard quit some years ago so using the emu is actually more convenient with the manual gain controls. I also note that audio levels will change with programs. I have diversity receive but export both main and sub receiver IF to two LP-Pan and on to a four-port soundcard (mAudio Delta44). This gives me two IQ channels for special SDR sw that I run on eme. I ensure the signals are in phase by running both LP-Pan from one LO (see mods under Linrad in the contents of Tech Topics on my website). 73, Ed - KL7UW From: Joel Black w4...@charter.net To: elecraft elecraft@mailman.qth.net Subject: [Elecraft] [K3] Sub RX and E-MU 0204 Message-ID: 52d2bfa8.40...@charter.net Content-Type: text/plain; charset=ISO-8859-1; format=flowed A few years back, I bought a CreativeLabs E-MU 0204 for SDR applications (i.e. SoftRock and Genesis G59).

Re: [Elecraft] KXPA100 Mobile Operations -- Power Output
Jim, Thanks for the suggestions on reducing noise. I can put common mode chokes (at least I think I can) on my DC wiring but I cannot effectively put in twisted pair unless I take out what exists now and replace it with twisted pair. Therefore, hoping not to have to do that I ask the following question. Question: How much difference will the twisted pair have in reducing noise versus having common mode chokes only? Currently with my Icom 706 the noise due to ignition and other sources is pretty high but the noise blanker does real good and getting it down to acceptable levels though not dead quiet as the case if the engine is off. I have a 2004 Chevy HD2500 (3/4 ton) crew cab pickup truck. The Hi-Q antenna is mounted on the rear (driver's side) on top of the side panel with my own custom made mount. I have ground straps at a number of locations and ground for the Hi-Q is very good (bolted to the frame itself after cleaning the frame for good contacts. The frame is also grounded to the under side of the body where I have cleaned off attach points to achieve good ground contact. 73, phil, K7PEH On Jan 12, 2014, at 10:57 AM, Jim Brown j...@audiosystemsgroup.com wrote: On 1/12/2014 10:26 AM, Matt Zilmer wrote: Wiring to the KXPA100 is 8 AWG, with two transfers to APPs at a relay enclosure for power control in the trunk.

Re: [Elecraft] KXPA100 Mobile Operations -- Power Output
Matt: Wow, a Honda Civic -- I think my Hi-Q antenna might tip over a Honda Civic :-) My vehicle is a 3/4 ton pickup truck, Chevy Silverado HD2500 Crew Cab so I have a large metal ground available. Thanks for your comments on your experience so far though. I know that my truck battery and charging system is pretty good and robust so I am assuming that I should easily achieve full output on the KX3+KXPA100. You raise another question though.

I can put common mode chokes (at least I think I can) on my DC wiring but I cannot effectively put in twisted pair unless I take out what exists now and replace it with twisted pair. Therefore, hoping not to have to do that I ask the following question. Question: How much difference will the twisted pair have in reducing noise versus having common mode chokes only? Twisting strongly rejects differential-mode coupling of the noise -- that is, the RF trash that appears between DC+ and DC-. There are two reasons why that matters. First, electronic systems in many vehicles are susceptible to RF, are poorly filtered on both DC and signal wiring, and misbehave when they pick up RF. The systems in my Toyota big SUV went into limp home mode with 50 watts on 20M. To get running, I had to remove the battery terminals from the vehicle so that the computers would reboot. The second way in which differential mode hurts us is if any of the gear on that DC is poorly filtered on its DC leads. That would let noise into our rigs. Currently with my Icom 706 the noise due to ignition and other sources is pretty high but the noise blanker does real good and getting it down to acceptable levels though not dead quiet as the case if the engine is off. Noise blankers are fine -- UNTIL a big signal outside of the RX bandpass pulses them. Then they're useless. The dual-mode blanker in the K3 is much better than most. I haven't used the KX3 enough to know -- I don't own one yet -- but I suspect it's pretty good I have a 2004 Chevy HD2500 (3/4 ton) crew cab pickup truck. The Hi-Q antenna is mounted on the rear (driver's side) on top of the side panel with my own custom made mount. I have ground straps at a number of locations and ground for the Hi-Q is very good (bolted to the frame itself after cleaning the frame for good contacts. The frame is also grounded to the under side of the body where I have cleaned off attach points to achieve good ground contact All that frame bonding is critically important for making the antenna work (by providing a counterpoise for the antenna), and it MIGHT help with RF suppression.

Re: [Elecraft] KXPA100 Mobile Operations -- Power Output
Oh... probably not. I've seen a couple Civics with Hi-Qs. Both had custom mounts, obviously. The main problem with a smaller car isn't the outside, it's the available space *inside*. I've been using Hustler for about two years now, with fair results. I'm not happy about the efficiency. I'm sure a commerical truck has a solid electrical system, pretty much all of them do. Suggest you use 8 AWG or better to get to the KXPA and/or any KX3 / other radio power distribution box though. 73, matt W6NIA On Sun, 12 Jan 2014 11:56:45 -0800, you wrote: Matt: Wow, a Honda Civic -- I think my Hi-Q antenna might tip over a Honda Civic :-) My vehicle is a 3/4 ton pickup truck, Chevy Silverado HD2500 Crew Cab so I have a large metal ground available.

[Elecraft] KXPA100 Mobile Operations
A couple of thoughts, derived from a million miles of HF mobling. Remember, most of the usable radiation ... by far ... from any center-loaded antenna is from the portion -below- the coil, and the Q of the loading coil is -extremely- important. Read Alan, K0BG's mobiling website ... a must-read- for any serious mobiler. Hustler's mobile antennas are always at or near the bottom of listed results at mobile antenna shoot-outs. Their coil forms are very lossy and the white shrink tubing used to cover the coils fits so poorly that standing water will collect under the cover.

What confuses me is what cables I need to order with the KAT500 - I see E850863 and E180980 cables. Obviously, I want to just place one order and make sure I have all I need but don't want to order anything I don't.

Re: [Elecraft] KPA500 and KAT500, befuddlement re: cables
Hi Joe, The KPAK3AUX Cable set (includes a DE15HD 15-pin cable, to attach the K3 ACC to the KPA500 AUX connectors, and a Y-Cable to be able to use the other signals on the K3's ACC connector, like DIGOUT1 to turn on the 6-meter preamp, or the band signals for an antenna decoder/switcher, plus a Keying Line Interrupter). You probably got this with your KPA500. When you get the KAT500 you should also get the E850863 cable, which is identical to the 15-pin cable you have in the KPAK3AUX cable set. (You can, though, use a 15-pin DE15HD cable (NOT a SVGA cable), but it is just easier to get the correct cable from Elecraft.) So when you get the KAT500, unplug the 15-pin cable from the KPA500 AUX connector and connect it to the KAT500 XCVR connector. (This give a 15-pin cable from the K3 == KAT500). Now, connect the E85o863 cable from the KAT500 AMP connector to the KPA500 AUX connector. Here's what is should look like: K3 ACC KAT500 XCVR KAT500 AMP === KPA500 AUX Where = are the 15-pin DE15HD cables. That's all you need to get going. You will NOT need a RCA keying cable because all the keying control is in the 15-pin cables. The Y-cable is used if you want to use, say, DIGOUT1 to switch a 6m preamp. Then plug one end of the Y-cable into the K3 ACC connector and use the two ends of the Y to go to the 15-pin cable going to the KAT500 and to the preamp. 73, Fred KE7X Fred Cady Fred KE7X The Elecraft K3: Design, Configuration and Operation 2nd ed The Elecraft KX3 - Going for the summit www.ke7x.com or www.lulu.com (Coming soon: The Elecraft KPA500 and KAT500 - the K-Line Dream Station) fcady at ieee dot org -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft- boun...@mailman.qth.net] On Behalf Of Joseph Carter Sent: Sunday, January 12, 2014 3:04 PM To: Elecraft Subject: [Elecraft] KPA500 and KAT500, befuddlement re: cables After 45+ years as a ham I am contemplating adding an amplifier - a KPA500 and KAT500 to complement my precious K3 and P3.

Re: [Elecraft] KPA500 and KAT500, befuddlement re: cables
Hi, Joe! I'd recommend a KPA500, a KAT500, one KPAK3AUX cable set, and one E850463 Optional KAT500 to KPA500 Cable. The KPAK3AUX cable set consists of three pieces, a 15-pin cable, a Y, and an little DB-15 M-F coupler with one pin cut that we call a key line interrupter. You might want more Ys if you have several things that need to go to the K3 ACC connector. I use two Ys for three 15-pin uses, amp/ATU, antenna switch, FSK/PTT to an interface box. The 15-pin cable from the KPAK3AUX cable assembly goes from K3 to KAT500. The E850463 15-pin cable goes from KAT500 to KPA500. And you'll need a few coax jumpers, K3 to KPA500 RF input, KPA500 RF output to KAT500 XMTR, and then your existing antenna goes into one of the KAT500 ANT connectors. The picture you need is in the KAT500 owner's manual, Figure 1. If you have a SteppIR controller that needs to also be able to interrupt the amplifier key line, then you need the Figure 2 diagram.

[Elecraft] Portable antnennas
Hello all, I would like to get some advice - based on experience - regarding the various portable antenna options there are currently available on the market. I am considering the buddipole system, super antenna, chameleon, and others. I am interested in hearing about performance and quality/ durability of the construction. I am not going to be backpacking with the antenna but portability and ease of setup is a consideration. I will be operating from 6m all the way through 80m. Thanks to all in advance.

Re: [Elecraft] Portable antnennas
Boy, are you ever going to get overwhelmed with info, Mark! :-)) You might want to join the NASOTA Yahoo Group and post your question there too, they're the folks that climb summits with radios and there is a huge amount of field antenna experience to be mined there. [insert all the usual disclaimers here, I'm retired and I have no financial interest in any product I am about to name] I had a full-up commercial BP for quite awhile. It is very well constructed, very sturdy, and customer service is very good. There is a BP Yahoo crowd full of good info. It is also quite heavy, relatively speaking, and takes awhile to set up and get tuned ... I had recipes for the tuning but still needed the impedance bridge. Despite pictures of a variety of arrangements for the BP, there really seem to be only two -- ground plane vertical and low OCF loaded dipole. Mine worked OK, best in vertical GP configurations where height doesn't mean as much as in horizontal ones. I finally sold it and bought an Alexloop. The cost is about the same although you can HB a resonant loop pretty easy for a lot less. It's a magnetic loop and is really a resonant transformer. It is MUCH lighter, way fewer parts, and I can set it up and take it down in about 5 min. I use it on a tripod for a Rain Bird sprinkler I got at Home Depot, it's a couple feet above me when I'm operating, and I can adjust the tuning. The Alex covers 40-10, although the loop isn't really large enough for 40m and the tuning is quite critical. 30m is better and it works great above 30m. Many of the SOTA crowd use end-fed half-wave wires. They are extremely light [just wire and a transformer], and they are fairly immune to the issue of Where is the RF Ground? They do require at least one support to get them up into the air. I'm pretty happy with my loop, it works at least as good as the BP, and it is easy to carry and set up. Those who run up mountains [NASOTA has them :-)] like stuff even lighter. Field operation, on a mountain top or in a local park is truly a lot of fun. There are a lot of field operating events, and Elecraft has some really cool field radios. I use my KX1 in the Spartan Sprint each month, and I use my K2 for summit activations. It's an element of ham radio that didn't really exist when I was a teenager. For the record, I'm 73 and a little orthopedically challenged so you need to adjust the above to make sense for your current age and physical situation. Good luck, antennas are one of the last bastions of home brew in ham radio. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 1/12/2014 4:14 PM, Mark Tellez wrote: Hello all, I would like to get some advice - based on experience - regarding the various portable antenna options there are currently available on the market.

[Elecraft] HAL ST-8000A RTTY T/U
Anyone on here using a HAL ST-8000A RTTY Terminal Unit with the K3? Looking for information on interfacing one to ANY ham rig, not necessarily just a K3 and also info on a good terminal program that will read standard baudot code over the RS-232 I/O of the 8000A. There used to be several terminal emulators that understood Baudot at 45.45 baud (60 wpm) but those I've been able to locate won't run on 64 bit Windows 7 Pro, even in a command prompt (DOS) window so I'm wondering if anyone knows of something that will actually work.

[Elecraft] KPA500 Power Supply Module Issue
FYI When I received my KPA500 kit, one of the three U3 leads on the Power Supply Module was very brittle and broke when I tried to reposition the heat spreader during installation. I obtained a new U3 and installed it. The amplifier did not work when the new U3 was installed, and the heat spreader became very hot. I found out the power supply PCB is a double sided board, and the three U3 leads must complete the path from top to bottom of the board. Upon removing (desoldering) the broken U3, I broke the path of one or more of these solder-through holes. I corrected the problem by soldering all three leads on each side of the board. The heat spreader temperature returned to normal, and the KPA500 came to life and has worked well since.

Xantrex can deliver immiedately. Matt, you reinforced my point of not being able to walk into a Walmart, Sears or Best Buy and pick one up off the shelf. There is no disputing that a Modified Sine Wave Inverter is very NOISY! And! A great majority of people buys the Modified Sine Inverters because they are cheaper, and easier to obtain. Also, the average guy doesn't even have the slightest idea of noise that is emitted from these beasts. 73 Milverton.

Re: [Elecraft] HAL ST-8000A RTTY T/U
Hi Jim: When I ran an ST-8000 (not A) 20+ years ago I usually set it up to regenerate the tones on receive. Then I ran the tones into a KAM and used an appropriate KAM type program. Transmit was usually from the KAM directly as the setup was simpler and I didn't see a real advantage in using the HAL. Today you could do the same thing with a sound card instead of the KAM. Might be able to regenerate on transmit as well - could be cleaner that way, don't remember if it's possible.

Re: [Elecraft] KXPA100 Mobile Operations -- Power Output
Matt, The dc wiring is not doing the job. You are seeing 11.2-11.8v running 60w! The battery under load should hold 13.2v if it is in good condition and fully charged. That is a voltage drop of 1.6v. You should not see that using awg-8 wire. You mention a relay in the trunk. What is the wiring from battery to relays? To find the problem first measure your battery voltage with engine running and with it off. Measure voltage at the amp when transmitting 100w with engine running and off. How much drop do you see from the battery? I would expect only about half a volt. Your battery should hold about 13v with engine off and transmitting full power. If it is dropping below 12v then the battery needs replacement. You said it shows 12.2v at the amp when engine running. That is too much voltage drop from the battery. You should see at least that with engine off and transmitting. The amp will not perform at full power with only 11.2-11.8v. It is also harder on the transmitting transistors as they have to draw more current to get power output and that translates to running hotter! Did you connect the awg wires directly to the battery posts? You should. Too often folks tie off wiring under the dash at the fuse block or connect to the cigarette lighter; those are bad ideas for running high power radios. Is this really awg-8? Resistance in 100-feet of awg-8 is 0.0628 ohms. Assuming you used 20-feet that would reduce to 0.013 ohms. Double that to include the resistance in the negative lead and its 0.26 ohms. If the amp draws 200w dc load at 12.5v that is a current load of 16 amps. The voltage drop = 0.026 x 16 = 0.4v Another tip is fusing both pos and neg leads near the battery connection. That protects the radio equipment from high current loads from other devices in the car (like a bad ground on the starter). I run 12v in my shack with a 16-foot dc wire run to a 30amp main fuse. I can run up to 400w dc load with this. My PS runs 14.2v and I have 13.5v at the main fuse under load. I run welding cable to accomplish this. 73, Ed - KL7UW From: Matt Zilmer mzil...@roadrunner.com To: Phil Hystad phys...@mac.com Cc: Elecraft Reflector Elecraft@mailman.qth.net Subject: Re: [Elecraft] KXPA100 Mobile Operations -- Power Output Message-ID: o3n5d9ttvgbubdkbbq1dpg4tpikvh36...@4ax.com Content-Type: text/plain; charset=us-ascii I've started testing the KX3/KXPA100 mobile configuration, but don't have all the cabling in yet and it's not permanent.

With the engine running, I am getting 100W. During key down at full power, measured voltage at the amp is showing 12.2V or more (depends on whether the regulator decides it's battery charge time, I suspect). With the engine off, I get between 11.4 and 11.8V at the amp with power set at 60W or below. Ymmv, because it would depend on the battery's state of charge and any other loads on it.
