Looks like we've both had some fun with these antennas that have become quite popular in recent years. My interest in Mag Loop antennas started back in the early 1980s, and I have designed and built a couple of dozen over the years since, mostly as experiments to gain knowledge and experience, and several to help friends who lived under extreme antenna restrictions. The two pictures in this Dropbox folder show one incarnation of a mag loop that uses flat mill stock for the main loop, and a trombone-style capacitor for tuning: https://www.dropbox.com/sh/gqbzz60bcwkc54h/AACAjWK6JFfyLN9qcvq9oSrqa?dl=0 My capacitor design uses PEXX tubing for the dielectric layer (must be protected from UV), and has fiberglass stiffeners inside the sliding part. The PEXX allowed me to run up to about 300 watts. And the stiffeners hold the tubes in line at the low capacity end of travel to prevent misalignment (sloppy tuning). I long ago moved to all copper loops and vacuum variables to handle high power and obtain better efficiency. An example of a two-turn version of a 40-80m mag loop is on my QRZ.com page: https://www.qrz.com/db/KB0YH It uses 7/8" Heliax (the shield) as the main loop conductor. Kinda heavy, so some of my newer mag loops use 1/2" Heliax or soft copper tubing instead. Performance suffers a little, but no one notices the difference. Have fun and keep safe.

Re: [Elecraft] Experiences using a portable HF loop
On 4/21/2017 9:00 PM, Ron D'Eau Claire wrote: The very BEST magnetic loops are incredibly inefficient, yet like any "incredibly inefficient" antenna one can make amazing contacts on them when conditions are right. If you use the suggestion that the loop perimeter (circumference for a circular loop) be 1/10 of a wavelength, then efficiency is quite low - on the order of 10%. This is the guidance given for small receiving loops to get the best nulls. However, a transmitting loop can have a perimeter of up to 1/3 wavelength and still have a constant current throughout its length (within 1% per John Kraus). This constant loop current is what defines a magnetic loop. The problem is with resistive losses. The day we have room-temperature superconductors, we will have efficient small transmitting loops. Until then, only a few percent of the power applied is radiated. My loops are typically a bit short of 1/3 wavelength at the high frequency of the tuning range, and no less that 1/10 wavelength at the low end. The efficiency of a 3/10 wavelength loop, for example, is in excess of 90% provided the resistances are kept low. I typically use the outer (shield) of hard line for the loop conductor and a series vacuum variable capacitor for remote tuning. It is also possible to use multiple turns to reduce the size of a magnetic loop even further. There is an example of a 40-80 meter mag loop on my QRZ page that uses 7/8-inch hard line in a two-turn configuration. Even though only 4.5 feet in diameter, it works quite well when compared to a typical back yard inverted vee or low dipole, and it can be hidden in an attic, the back of a garage, or tucked out of sight among trees or bushes. 73, Gus Hansen KB0YH __ 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] Magnetic Loop Antenna Question
The length of hardline provides both an inductor (the shield) and a series capacitor (the center conductor to shield). It is an interesting experimental loop antenna, but not particularly versatilefor general use. There is a picture of my two-turn mag loop for 40-80m on my QRZ .com page. I wrote an article for antenneX several years ago describing this antenna, but it is behind the "pay wall" so I can't post it anywhere else. The main loop is about 4.5 feet in diameter formed by using the shield of 7/8-inch Heliax. The loop is remotely tuned over the coax by a DC motor-driven vacuum variable capacitor. The antenna can handle between 500 watts and 1KW depending on frequency if the VVC is stout enough (15kV at 60 amps). The driver loop is about 1/5 the diameter of the main loop diameter. 73, Gus Hansen KB0YH On 11/13/2016 11:57 AM, w7aqk wrote: Stan, Well, my first question was "how about the capacitor?".

Re: [Elecraft] K3 audio quality
Hi Jim, ... It's all very simple physics. Look at the size of the loudspeaker. Its low frequency output is limited by its size as a fraction of a wavelength. The K3 and K3S are designed as compact, light weight radios. The speaker used is quite good for its size. If you want big bass, you need a big loudspeaker (or at least one a lot bigger than the little guy in the K3 and K3S). BUT -- ham radio is NOT about high fidelity, it's about COMMUNICATIONS quality sound. Having the sub receiver doubles my listening pleasure. I use a pair of old RS Minimus-7 speakers with my original K3, and am using a pair of Jensen Powered Speakers (JPS 45) with my K3S. Getting excellent sound from both systems. Nearly a century ago, Bell Labs learned through a lot of research that all it takes for communications is smooth (flat) response between about 500 Hz and 3 kHz, and the telephone system was designed around that bandwidth. As a former Bell head (BTL in Denver) working on PBX systems in the 1970s I was exposed to the training for many telephone products. The plain old telephone service, POTS, was designed for a 3000 Hz bandwidth (300-3300). In the 1960s while earning my EE degree I worked in the broadcast business. Our main studio to transmitter link was an equalized line, but the backup circuit was a POTS line. Fortunately we didn't need to press it into service often, but on those occasions it sure sounded crappy by comparison to the usual AM 6 kHz or so eq'd circuit. And much more so when we added an FM station to the mix. 73, Gus Hansen KB0YH __ 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] Koss SB-45 Headset, update on comfort
Hi Jim, Electret and dynamic mics are equally good for ham radio. Use whatever comes with the headset you like and be happy. All that matters is that electret mics need bias turned on and dynamic mics do not. Do you know why Elecraft calls the power provided to an electret element BIAS? Unlike the large form condenser microphone elements that need both polarizing potential and preamp power, usually provided via a "phantom power" circuit, an electret element is permanently polarized. The power applied via the phantom circuit is actually providing only the drain voltage for the FET preamp in the electret microphone capsule, not any kind of biasing voltage. Of course we have similar terminology used in systems that provide control voltages or operating power to remote equipment: The so-called BIAS-TEE used to inject and extract power over a coaxial cable, for example. I haven't found any official documentation for these types of circuits that uses the BIAS moniker. Are there any references that you might point to?

If they stay up, they were too small. Nah, let's get Craig started in the right direction. When I got into ham radio in the 1970s I often heard the expression "if your antenna didn't fall down last winter it wasn't big enough." But that's kind of like saying "If you're driving on the highway and you don't crash you're not driving fast enough." I prefer to suggest that we should try to design and construct antennas well so that they stay up and work right. Putting a pulley and weight on the support of one end of a dipole suspended between two trees to accommodate tension changes from wind is an example of good technique. Happy antenna building Craig.

Re: [Elecraft] W1 versus WM1

The WM1 Computing Meter is a product of Autek Research. It is a very nice 20/200/2000 watt power/SWR meter with selectable average and peak reading capabilities. SWR and power are shown simultaneously on separate meters. This is a very good quality meter that I have used for many years. For my QRP work I also have the OHR WM-2 wattmeter. It, too, is a quality instrument, and it allows you to make accurate forward and reverse power measurements on 10/1/0.1 watt scales.

The ANT1 position is the one that is activated by the AC control voltage. 2) I mistyped the RFC/choke value. The value of the RFC in the remote switch box measured with an AADE L/C Meter IIB is 70uH in circuit. It is probably the same as the RFC in the control box that measures ~100uH. Also note that the current version being sold by MFJ/Ameritron uses the three-relay circuit with a modified layout of the connectors, which I assume is to minimize any impedance bumps. The two-relay version I mentioned in the previous post has provision for jumpers that ground the unselected ANTx connector center conductors. Neither of the three-relay version support this feature.

I'm running only 100 watts for this contest, but it can handle full legal limit with ease. This antenna system provides a minimum VSWR of about 1.4:1 at resonance (28.5 MHz) due to the slight mismatch (75 vs 50 Ohms) and less than 1.7:1 at the 10 meter band band edges. 73, Gus Hansen KB0YH __ 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] K2 with the W2 Wattmeter kit
Hello Ray, ... thinking of getting the Elecraft W2 wattmeter kit. Good choice. I believe the W2 is really designed to interface with the K3 but will it also work OK with my K2? Works with any transceiver. The RS232 interface is for f/w updates and data displays via an attached computer. If so, do I position it before or after the tuner? Depends on whether you are using a rig's internal tuner or something external. In my station the W2 is installed between the KPA500 output and an external tuner that I use with an all-band doublet. The K3's KAT3 is bypassed in this arrangement. 73, Gus Hansen KB0YH __ 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

Still haven't looked into repairing the Astron, but understand it is not an uncommon failure. I had a similar failure with an Astron 18 amp supply. It would work well for a while then cut out under load intermittently. The problem was a wire connected to the circuit board that was making mechanical contact, but had never be soldered. After soldering the wire, I checked all the other solder connections and touched up a couple that looked marginal. All has been well since.

My questions are : 1. practically speaking, apart from huge traditional wire antenna, are there any other antennas of managable size (also reasonable efficiency) which can be easily set up under distress situation? I built a magnetic loop that covers the range of 160-80 meters. It consists of three turns of 7/8 hard line as the loop conductor and a remotely controlled vacuum variable capacitor for tuning. The antenna is just a tad over six feet in diameter. It can be tuned down to about 1.5 MHz with a 500 pF vacuum variable. With a longer loop conductor (either more turns or larger antenna diameter) and a 1000 pF VVC, such an antenna could get down to the 600 meter band. The instantaneous bandwidth is quite narrow (~2 kHz), suitable for CW and data modes, but not SSB. 2.to make communciations of say within 200-300km, what ERP is required? I have worked all over North America from Colorado (~2000 mile range) with this antenna running only 100 watts during several contests, and daytime regional coverage is typically out to about 200 miles using 500 watts. The antenna hangs from a tree branch with the bottom of the loop about 8 feet above ground. 3.for a segment of 15Khz, voice communciation seems quite restrictive. How efficent will it be under digital mode (not CW) such as Pactor? The three-turn mag loop typically has a 10-15% transmitting efficiency at the low end of its tuning range if it is built well, and the nulls along the loop axis help in reducing at least one noise source, providing acceptable S+N/N performance on receive. - Johnny, I can send you a picture of my 160/80m version of this mag loop if you want.

Re: [Elecraft] High End Paddles
Darrell Bellerive wrote: That seems to run contradictory to what I read in this thread and on eHam. So, do those of you who have used both the BY-1 and Hex Paddle agree with Bencher's views? Is the BY-1 really better for those using a light touch? I tend to be a bit heavy-handed with the paddles. Having both a BY-1 and a Hex Key I prefer the Hex Key. It stays put on the table and has a great feel. And it doesn't lift and separate the way the BY-1 does if you apply any upward pressure to a paddle. My Hex Key is the Bencher brand -- got it before Elecraft started selling the paddle under its label.

I don't have an electronic keyer. I want to practice sending on a pc. What else do I need to buy ??? an electronic keyer and serial cable ???Jesse Nicky wrote: Jesse, To use a PC for sending code practice you will need an electronic keying circuit to convert the dot and dash closures of the paddle into an on/off signal that drives an oscillator at a pitch and volume that is pleasing to your ear. When I was writing Learn C Now for Microsoft, I wrote a C program that used two pins on a parallel port for the keying input and some sound routines to generate the tone. It worked, but didn't make the cut due to space limitations and concerns that it was too geeky for the intended audience. I can't lay hands on it now -- lost to the dust-bin of history. However, you are very close to having what you need with the K2. Forge ahead with Part 3 and you will be able to use the K2's built-in electronic keyer for practice. 1) Set up the keying input for paddles: Tap MENU and select INP by rotating the tuning knob. Press and hold MENU to get into EDIT mode and select PDLN (normal) or PDLR (reverse). Tap MENU twice to get back to normal operation. 2) Then with the rig in CW mode, activate the TEST mode by pressing and holding the MODE button. When you want to get on the air for real, press and hold MODE again to return to OPERate mode. If the default sidetone pitch and volume aren't right for you adjust those parameters using MENU/EDIT actions for ST L and ST P settings.

Re: [Elecraft] What's Happening at the Elecraft Dayton Booth? New Products, Building Demo, T-Shirts, Amp and More.
In addition, we'll be previewing one of our new solid-state auto-tune linear amplifiers (KPA1500). Pictures of the above can be seen at: http://www.elecraft.com/news.htm Nice to see the amplifier. Looks great! One little problem. Either the caption on the photo page (and the reference above) is wrong, or the amp has been mislabeled (it shows KPA800). Is it reasonable to assume that the two amps look nearly identical? I hope you sell a lot of them.

Re: [Elecraft] What's with the new amplifier?
On 2/14/06 11:46 AM, Jeff Stai [EMAIL PROTECTED] wrote: ps: I think the Alpha does have an antenna tuner...? Hi Jeff, The 87A doesn't have a built-in antenna tuner. The output network can comfortably match about a 2.5:1 VSWR range as I recall from the one I had back in the early 1990s, but I had to use an external tuner to use the Alpha with my wire antennas.

Re: [Elecraft] RANT front end protection
On 2/8/06 3:14 PM, Gil Stacy [EMAIL PROTECTED] wrote: I have seen advertised front end protectors recommended for use when utiilzing a separate antenna for receive. Does the K2's RANT option on the 160 board offer sufficient protection for use with a separate preamp and RX antenna or is it prudent to use a front end protector such as designed by KD9SV? Thanks, The K2 is the only current production HF transceiver that I know of that has the front-end saver built in. The RECEIVE ANTENNA RELAY, K2 on the K160RX board, disconnects the RX antenna during transmissions. If you're running a standalone station, no problem. In an SO2R or other multi-station contest environment (or if you have a big gun station next door), you will probably need to take additional protective measures. Your best bet is to get a copy of Managing Interstation Interference by W2VJN (George of INRAD fame). He does a great job of describing the problems and solutions.

Re: [Elecraft] ATU problem
On 11/14/05 5:27 PM, Slater Tubman [EMAIL PROTECTED] wrote: I have in ATU installed. When I attempted to tune the rig, I got a Lo P reading. First time I ever had that. The ATU manual says that POWER setting is too low. I get the same result, regardless of the power setting, regardless of the band, regardless of the antenna. Is old age getting me, or have I overlooked something very basic, or what? Any advice will be appreciated. Hi Slater, Check to see if you have the rig set to TEST mode instead of OPER. You change this setting in CW mode by using the VOX button. If it is in TEST mode the rig doesn't transmit and the diagnostic message is Lo P when you try to run TUNE. (It happened to me once after I did some practice sending with a new Hex Key paddle.)

RE: [Elecraft] K2 - VOX - Straw Poll
I am asking for feedback from SSB operators on VOX operation on the K2. a) Do you use VOX ? Yes, about 95% of the time when running SSB. The microphone I use is a homebrew boom-set that has an electret element. It has plenty of output and triggers the VOX quickly and reliably. I would very much like the K2 to have a dedicated vox on/off control. Having to cycle through the menu, especially on a hold type button, is a pain. It is hard to eliminate a sneeze or other sounds not intended for transmission. b) If not, why not ? I turn VOX off if I'm operating in a noisy environment, such as portable operations when the planes from a nearby airport are taking off in my direction. 73, Gus Hansen Email: [EMAIL PROTECTED] ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
