Re: [Elecraft] LP PAN
The LP-PAN Software Defined Panadapter works fantastic. I use the K3/LP-PAN/PowerSDR combination and it far exceeds the panadapter display on my IC-7800 in both weak signal sensitivity and real time display refresh rate (not to mention the ability to mouse click on a displayed signal and jump the K3 to it's frequency). I'm so spoiled that I seldom use the 7800 for CW operation anymore. Add to that CWSkimmer (running at the same time) and I died and gone to heaven ;-) Frank - W6NEK - Original Message - From: N1IX n...@n1ix.com To: elecraft@mailman.qth.net Sent: Tuesday, July 21, 2009 10:20 PM Subject: [Elecraft] LP PAN I have noticed a lot of LP Panadaapters for sale.

Re: [Elecraft] k3 and n1mm comm problem
Try getting an adapter with an FTDI chipset. I can't guarantee that it will solve the problem, but it did solve all the problems I have experienced with Prolific chipset adapters, and one distributor of USB devices states that the FTDI adapters are more reliable than the Prolific adapters. - Julian, G4ILO.

Re: [Elecraft] Big Coax on Dipoles
Good morning Jim, Thanks for your e-mail. I also use tall trees to support antenna catenarys, which are made from 6mm dia woven marine rope, along with marine pulleys, and a counterweight at one end of each catenary. The counterweight for each catenarys is fused, so if another tall tree falls across a catenary or antenna during a storm, the catenary/ antenna will come down under the tree without serious damage, and the rope will still be running through the support pulley which makes it easy to hoist again after the fallen tree is removed. At one time I used airborne coax feeders here but replaced them with open wire feeders, after somebody shooting pheasant on the farm filled a coax feeder with lead shot. 73, Geoff GM4ESD On Wednesday, July 22, 2009 at 6:03 AM, Jim Brown wrote: I have four fan dipoles suspended at 100-120 ft between tall trees (redwoods), all fed with RG8 or RG11.

Paul, That should be fine. The K2 itself is speced for up to 15 volts input. If you want a refinement over the K2 display of voltage, measure the voltage right at the terminals of a fully charged internal battery. If your battery was not fully charged when you cranked up the power supply, check the voltage over the next several days and re-adjust the power supply as needed. 73, Don W3FPR pkhjr wrote: I installed the battery in my K2 and adjusted the voltage up on my astron.

Re: [Elecraft] Big Coax on Dipoles
The feed point on some of those bands would see a 150:1 swr (no kidding)! Your efficiency would be about 5%. Your tuner would still see a low swr and it will be an easy match because of the tremendous loss in that 100 pounds of coax. Sure you can work stations, with that height you could QSO with a light bulb, but you would be 100 times stronger using ladder line plus you wouldn't need 95 pounds of sand to hold up that lossy dummy load coax. I'm feeding a 200' doublet with ladder line then to a 4:1 current balun next to the K3. The K3's internal tuner finds a match on 160-6 meters and I have very little power loss on any band.

Re: [Elecraft] K3 and amplifiers such as ALS-600
No, you do not need it. I have an AL82 I am keying right out of the back of the K3. Works fine. Usually, it is a 12 volt time for keying the Ameritron Amps. I am not sure I would do that with just any old amp, but the Ameritrons use 12 volt keying line and not the 130 of the SB Line.

Re: [Elecraft] LP PAN
Dave, I purchased a LP-Pan and a E-MU 0202 a few weeks ago and had no problem getting either of them working and interfacing DXBase. I wonder if you have given Larry a call at Telepost? The only minor problem I had was with the PowerSDR software. For reasons only known to the computer gods, it would not load correctly and when I tried to run it, I would get three or four fatal error messages. I even tried to un-install it and then re-install with no luck. There was an easy fix that involved formating the hard drive and then re-installing Windows XP (a ritual that should be done once a year anyway). Fortunately, formattng the hard drive and re-installing XP is pretty easy, but time consuming to download and install all the updates and programs. With the fresh install, everything worked the first time. I did have a couple of procedural questions, and a couple of quick calls to Larry answered those. It works really great and well worth the time and expense of installing it.

Re: [Elecraft] K3 and amplifiers such as ALS-600
Is it best to use a buffer send/ptt device like the Ameritron ARB-704 with the K3? Not necessary. The ALS-600 keying input has an open circuit voltage of 12VDC, and requires you to sink 100ma (or 70ma with the QSK mod) to key the amp. Easily handled by the K3 amp-key RCA output. If you have a new ALS-600, ALS-500 or ALS-1300 with the ARI-500 for auto-band switching, the K3 band data output works great. You do need the K3 TTL band data mod if you have an early K3 as the ARI-500 does not have pull-up resistors. The K3 TTL band data mod is also required for the THP HL-1.5 amp, but not for the HL-2.5 (the HL-2.5 has internal pull-up resistors). As I recall, the SPE EXPERT amp has internal pull-up resistors as well - but I'm not 100% certain about this.

ALS-600 - no Unmodified SB-200/220 - yes FL2100 - yes Basically put - check the voltage on the amp's relay line. If it is AC, or a higher voltage, or if it is higher current to pick the relay, than is specified in the K3 specs - use the ARB-704. And, yes, you can use the ARB-704 with any amp, even though it may not be needed. 73HankK8DD GET FREE SMILEYS FOR YOUR IM EMAIL - Learn more at http://www.inbox.com/smileys Works with AIM®, MSN® Messenger, Yahoo!® Messenger, ICQ®, Google TalkT and most webmails __ 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] clear function from M1-M4 memories
If I read Steef's question right, it was not about erasing a stored CW message, but removing a programmable function assignment from one of the Mx buttons. The answer, as provided by KB8AP earlier today, would be to tap REC, then the Mx button in question, then REC again. By the way, the function isn't stored in the CW memory - it's a button override in firmware. The CW is still stored in the memory, and you can regain access to it as above. ~Iain / N6ML Dick Dievendorff wrote: Steef: You should be able to remove a CW message stored in one of the CW message memories with the K3 Utility.

Re: [Elecraft] Max-Gain MK-8
Well, maybe I'm being a little picky here, but the Arrow 2m/440m j-pole is not a j-pole antenna. Arrow calls it an open stub j-pole - but it's a new creation and borrowing the popular j-polename. Looking at the pictures - the vertical element which has the coax cable attached to it - well this item appears to be complete insulated from the rest of the antenna. Look at the parts list and there is a plastic sleeve/washer that insulates it from the rest of the antenna. I think the other vertical elements probably do nothing at all except to make it resemble a jpole? Or maybe these additional elements are parasitic elements - similar to a yagi's elements. How does this antenna work? I don't know. That's why I didn't buy it. Instead I got a co-worker to teach me basic plumbing soldering skills to build a Super Cactus J-Pole antenna. It has more gain that a regular J-pole. Including soldering tools, I certainly paid more than buying the Arrow open stub j-pole - but I don't want an antenna I don't understand. The Super Cactus J-Pole works well on my Winlink 2m RMS station. Howard list1 wrote: I used an MK-8HD (50') for Field Day.

Re: [Elecraft] Big Coax on Dipoles
Re: 150:1 SWR. I have an inverted vee style dipole consisting of two wires fed in parallel at the feed-point, one cut for 80/75 (depending on some jumpers at the ends) and the other for 40-meters. The feed is at about 45 feet above ground and the low-freq dipole ends are at about 25' above ground. The wires are displaced horizontally (fanned) about 25 degrees from each other. I have a pretty accurate model of this antenna, that has be confirmed against actual measurements on the two bands using my N2PK vector network analyzer that was calibrated at the end of a 50' run of cable necessary to get from the antenna to ground. The tower is about 125' from the shack so the total run of RG-213 is about 200'. The modeled worst case SWR occurs on 20-meters where it is about 32:1. Including the transmission line loss decreases the SWR to under 5:1 over all of the ham bands from 80 thru 6 meters, with the worst case still being 20-meters. The worst case line loss is a bit over 8 dB, with 20 and 10-meters being the culprits. Since I have a HB three-element Yagi for 20, that band is not an issue and I can work all of the other HF bands using only my L4-B active tuner. I've also worked about 120 Q's on 6-meters using the K3 (no tuner) and have about 20 states worked and 5 DXCC countries, including a couple of JAs on that band using the same antenna. (Editorial mode on: The JAs were worked on Field Day and I worked them about an hour apart. The first one was still calling CQ without success when I worked the second. So the band was open for DX but no one (except me) was listening.) However, this is in no way an endorsement of using such a system as an all-band antenna, even one fed with ladder line. These antennas are at best compromises, with generally unknown performance characteristcs, and at worst not much better than dumy loads.

I have four fan dipoles suspended at 100-120 ft between tall trees (redwoods), all fed with RG8 or RG11. There is no problem supporting the big coax. The keys to success are robust mechanical construction so that you can establish high lateral tension. If one of the objects you're suspending from is a tree, one end needs a weight and pulley to adjust to wind conditions. I use 6.5 gallon water jugs filled with dry sand (roughly 95 pounds), and the trees are typically 140-220 ft apart. I use 5/16-inch dual woven poly rope, #10 solid copper, and robust insulators. Do they sag? Sure -- at least 10 ft on the long dipoles. Does it matter? No. One of the side benefits of the big coax is that my 80/40 fans (at right angles) work quite well on 30M, 17M, 12M, and 6M, thanks to the lower loss with moderate degrees of mismatch.

[Elecraft] K3 s/n 1169 21MHz band distortion
I have noticed whenever I used the transciever on 21MHz (rare since band conditons are so poor) a distortion of received signals. I listened to the transmitted signal using on other receiver(s) and it is quite noticeable. Especially when comparing the purity of the CW note on 14 and 28 MHz. The recieved signal distortion is difficult to describe. The amount of distortion varies from signal to signal. And it does not seem to be a function of received signal strength. I switched power supplies, no change. Switched from using an external antenna to a dummy load and no change in the sound of the transmitted signal purity. I think the best illustration of this would be for me to call a service technician and let them listen to it. That would at least let them hear what I am experiencing. Thank you for your assistance.

Re: [Elecraft] RTTY Dual PB
I have had issues with this alsoon several levels. One, hen I have used the feature, it seems the sensitivity of the received signal is diminished. Second, I have found that the power output reduces by about 10 to 15 watts. Not much, but still, something isn't right there. I have had no trouble using my 500 Hz roofing filter and going down to 200 or 300 Hz and working RTTY. The PB setting, although a great feature, has not flipped my skirt up. Something is not right. I have asked the questions about the power issue and they are looking into it. This has been several months.

Re: [Elecraft] K3 and amplifiers such as ALS-600
MRF150 as used in ALS600 has 17db linear gain at 30MHz, and +20db on 20MHz and below. The gain is reduced to 9-11db across the bands by swamping the input and by some feedback. It can be recovered by using smaller or no input resistor and by removing or reducing the feedback with a risk of some instability. Apparently ALS 600 does not suffer from instability. The data sheet for MRF150 cites IMD3 at -32db in a circuit without any feedback. Linearity is another issue.

Re: [Elecraft] K3 s/n 1169 21MHz band distortion
Hi Jack, Noise blanker settings can be remembered per-band, and very aggressive NB settings can cause distortion. Is it possible you have set the NB levels for the 21 MHz band to very aggressive settings (e.g. dsp t3-7 and/or IF wid7)? Press and hold the NB button when on the 21 MHz band to see what settings you have and compare them to the settings on other bands. Of course, turning the NB off for the 21 MHz band could tell you right away whether that's the problem or not. Just a thought. 73 -- Joe KB8AP On Jul 22, 2009, at 1:20 PM, Jack Colson wrote: I have noticed whenever I used the transciever on 21MHz (rare since band conditons are so poor) a distortion of received signals. __ 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] Keying A Small Amp With A K2
Hi All, I haven't been paying much attention to the conversation here about keying amps, etc. since I rarely use one. However, a situation has arisen which suggests I should have paid closer attention. I have a couple of small amps--an HL50B, and an HLA-150, that work well with QRP rigs for a little extra boost. The HL50B works best with the K2 (and other QRP rigs) as it has good RF sensing, and keys right up when you hit the paddle. The HLA-150, however, doesn't do quite as well. It supposedly has RF sensing too, as well as auto band switching, but on CW I find that it is just a tad slow in triggering. Accordingly, it tends to cut off the first dit or dah. That's about the only complaint I have about it though. With less than 10 watts of drive you can get over 100 watts out. The auto bandswitching works very well. The HL-50B puts out about 60 watts with 5 watts of drive. The HLA-150 has a keying line input jack for direct connection to a transceiver. However, the K2 doesn't have a keying line output that I'm aware of. So, my question to you amp gurus is what would be the best (easiest) way to make this work? I'd take my HL-50B, but I left it up in Oregon with my motorhome. I'll rectify that mistake the next time I get up to Oregon. Any suggestions?

Re: [Elecraft] LP PAN
Brett, Thanks for pointing it out. It was an old screen shot. I updated it to a more recent one as the package does provide frequency control. As for the bandwidth of the display, it's purely a function of the sound card. On Linux, the EMU-0202 sound device supports 44.1 KHz unless it's sent a USB command to change sample rate. I've worked with some other Linux folks around the world to help fix this, and the results should be coming out in new versions of the Linux ALSA sound system soon. Unfortunately, it doesn't seem to get past 96 KHz. (The Mac driver for the EMU-020 has this same limitation.) You can use quisk and the LP-PAN with a less expensive sound card such as the Griffin iMic or a 48KHz Creative USB product, all in the $40 range, and get a 48KHz bandwidth view coverage. If you're a CW or digital mode operator, that's pretty much all you need, and it's about half the cost of the EMU-0202. I don't know what Elecraft's plans are, but I believe there's room for both standalone display devices and shack computer integrated devices. Quisk is an option for those of us who have the LP-PAN and use Linux in the shack. Leigh/WA5ZNU On that screen shot is that + and - about 20Khz? Shouldn't the system be able to pull off 192Khz total width? It would also be really slick if the waterfall was labeled with absolute values rather than relative ones. Honestly the only reason I haven't purchased an LP-PAN is because all the computers at the house are running Linux. However I'm also VERY hopeful that the Elecraft bandscope when it comes out doesn't require a computer of any kind. I'm not certain on my feelings of requiring that the device needs a VGA monitor. I really hope that the thing is completely self contained and even better if it was a box with an LCD of some sort and fits nice right on top of the K3 and looks like it belongs there. I guess time will only tell ~Brett On Wed, 2009-07-22 at 13:27 -0700, Leigh L. Klotz, Jr. WA5ZNU wrote: Linux users can install quisk-lppan-k3. It's a far simpler user interface than the PowerSDR software. We're hoping to port it to Windows as well some day. It can control the K3 directly, or work through fldigi, which is a digimode program that itself runs on Windows, Mac, and Linux. http://wa5znu.org/2009/04/quisk-lppan-k3/ Leigh/WA5ZNU __ 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 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 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
