Re: [Elecraft] Transverter for 70cm?
BTW, I think DEM plugs Elecraft as well and offers tips on interfacing Elecraft with their transverters. I first heard about Elecraft while going throught he DEM website. I thought who the heck is Elecraft, never heard of them but eventually I figured it out! Mark , George Be carefull with the DEM EKT1 interface , is has no Vrfdet circuit. K2 does not work well without it , ofcourse no power regulation with the K2 power potmeter , but also CW sounds bad . Better to use the original K60XV. 73 Nanko PA0V ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Elecraft Growth Metric
Hi All, Sunspot count is low and I'm at a bit of a loose end. Latest version of QST arrived. Check the Elecraft advertisement - it has grown again. So my question is: How long do you think it will be before Elecraft needs/has a full page advertisement?

[Elecraft] antenna suggestions?
Brian: If you have ANY metal nearby (e.g., railing), you could use the vise-grips mount and a hamstick, or better an Outbacker. The mount is basically a set of pliers with a stud welded on the tip. Using the Outbacker gives you the freedom to change bands simply by changing taps. This portable antenna system is easy to set up and move, works well, and is relatively inconspicuous. The great advantage is that it will be resonant on your operating frequency and not require a tuner. 73, Jim K5HO - Nunquam Secundum snip So - any antenna suggestions? Preferably something inexpensive and easy to build as I have almost no tools here. Some ideas I've been thinking about are a random wire (using the tuner), a homebrew buddipole, perhaps a magnetic loop to stick by the window, or a shortened vertical.

Re: [Elecraft] MH2 Microphone Discontinued
Hi The TenTec handheld microphone works great with the K2. It comes with a 4 pin connector that you will need to change to the 8 pin connector for the K2. This mike works fine with the 5.6K bias resistor from the 5 volt supply to the AF pin, just like the MH2. I have also used the TenTec desk mike on the K2, however it really needs 8-9 volts rather than the 5 volts provided by the K2. You can use the internal 9 volt battery or jumper over to the 8 volt supply in the K2.

I can't speak to the ATU issue of poor efficiency on 10/12 meters since I don't have a KAT100. The droop on 30-15 meters from the KPA100 suggests an issue with the bandpass filters. The KPA100 typically exceeds 100 watts output quite easily. The fact that yours doesn't suggests low supply voltage or a measurement error that is showing a slightly low output across the board. Suggest you look very closely at your bandpass filter components for the low bands. The KPA100 manual also has a procedure for checking the bandpass filters using an antenna analyzer, if you have access to one. Just for the record, here's what my K2/100 delivers at full power into a dummy load: 160: 112 watts 80: 108 watts 60: 110 watts (legal limit on this band is 50 watts erp, of course) 40: 112 watts 30: 107 watts 20: 105 watts 18: 111 watts 15: 106 watts 12: 104 watts 10: 106 watts at 28 MHz, 46 watts at 29.5 MHz That roll-off at the upper limit of 10 meters is normal I believe. Of course the difference between 100 watts and 112 watts in what another Ham will hear on the air is completely insignificant, but it demonstrates that the KPA100 will meet the 100 watt transmit specification across the HF bands.

[Elecraft] KPA800/1500 Power Question
Well, just to complain a little the KPA800 was not shown to the regular attendees at the Elecraft booth at Dayton. Darn, really wanted to eyeball it!! I hope my money is as good as that of the next guy. I was even considering how to squeeze it into my budget. Now my real question. Does anyone know what the AC power requirements are for both models. I'm bringing more power into my shack this summer and it would be great to know what power is required. I've heard a figure of 70+ percent efficiency but my thinking is closer to 40-50 percent.

[Elecraft] BL-1 and BL1-1 Balun Questions
Greetings folks; I started building the balun kit, and I am suffering a bit of confusion, that I hope to get some help straightening out here. 1. In my ignorance, I cannot tell whether I am building a 4:1 or 1:1 balun; though the included instruction sheets are almost the same (the BL1 refers to a Binocular Balun core - I assume the ferrite core with parallel holes, the BL1-1 does not in the parts lists, both refer to winding the balun. They both refer to winding three turns around the balun core. So, ignoring the question of what I ordered for a minute, how do I tell which I am building? 2. There seems to be no way to get three turns around the core with the wire length provided; the instructions show what appears as the wires starting on one side of the core, through, around so on, so that you end up with 3 windings visible around the outside edge of the core, starting at one side and finishing at the other. I seem to be only able to get 2 turns, leaving 1 on one side, and about 2 at the other, with the windings pressed fairly tightly to the core. If I take the prescribed 10 length, subtract the 1 off both ends, I am left with 8 with which to get the 3 turns, the circumference of which calculates for me to be 3*3 or 9... (I am assuming each turn takes 1 through, about .5 to make the turn, another 1 around, and another .5 to make the turn to go in, making 3 per turn) -.5 because the last winding need not turn and another .5 because the first through need not turn either, so 9 - 1, = 8, the remaining length, so it would seem to be in theory possible. But in practice, I am failing to be able to perform this feat. I am hoping there is some simple if you know it trick to get me rolling again. Thanks in advance! --Dave -- David F.

RE: [Elecraft] BL-1 and BL1-1 Balun Questions
Hi David: You asked about how to get the three turns on the BL-1 core. Three turns means that you see TWO loops of cable going down the outside to of the core on each side. (Remember, turns are *always* counted by the number of passes through the center of the core). For each hole, the wire starts at one end of the core, goes through the hole (that's turn 1), loops around the outside, back through the same hole (turn 2), around the outside the second (and last time) then goes back through the same hole (turn 3) one last time. Where it starts at one end you'll strip and solder to the terminals on the board near the coaxial input connector and where it ends at the opposite end you'll strip and solder the wires to the terminals at the output end of the BL1 board. I have a hunch you're trying to see three loops of wire around the core on the outside: that's why it won't fit and there isn't enough wire. That would make four turns! You wanted to know if you were building the 1:1 or 4:1 version. The ONLY difference between them is how the windings are connected at the output end of the board. If you hook the red and white leads to the circuit board pads as shown on the board - white leads to white pads and red leads to red pads, you'll have a 4:1 balun. If you want a 1:1 balun, connect the two white leads together and connect them to the pad marked WHITE nearest the edge with a number 2 on the board, then connect the two red leads together and connect them to the pad marked RED at the edge with the number 1 on the board. The inner white and red pads are not used. That's the only difference between the 1:1 and 4:1 versions.

[Elecraft] (no subject)
Hi all... I think I have a problem! With K1 I am having a problem and I think it is setting the power up for 5 watts. Without touching anything right now I have a SWR 1.1 and a output of 1.9 watts when I adjust the internal tuner. I have a 3KW tuner in the circuit and am using the bypass switch on the tuner and using the internal turner in the K1. I have read and re-read the manual on Page 54 where it tells how to set the power out put but possibly am not doing it right. I know I am using the out menu to adjust power. When I send CW however, I see 6 bars on the S-meter so I assume I am getting full output?? Any help will be appreciated. Right now I am going to the Panera Bread Restaurant and drown my tears in a 1/2 Greek Salad and sandwich! g BTW, I am using a 27 AMPHR battery which I use with my 706, and it is at present charged to 13.2 volts.

[Elecraft] KX1 Voltage
On page 62 of the manual, right side top, it states: You can connect any 7-14 V DC power supply or battery to J1, although you should use the minimum recommended voltage (8 V) when possible... Why does Elecraft recommend that the KX1 only be run with 8 volts? That's even less that a new set of Lithium batteries would produce. Any comments?

Hopefully, no one puts a brick on their key at a kilowatt output! Electric rates vary widely around the country too. Here our little local Utility charges a bit under 3 cents/kilowatt hour (our power comes from the Columbia River hydroelectric dams) and other places have quoted over 20 cents/kilowatt hour. It's tempting to run a kilowatt to a poor antenna in an attempted to get out better, but keep in mind that short antennas, such as one tends to have in cramped quarters, produce HUGE RF voltages, even at low power levels. Back in the 1950's some famous (or infamous) mobilers experimented with kilowatt mobile rigs. Keep in mind this was in the days of vacuum tubes. Such setups often used several generators attached to the automobile engine and a whole back seat area of the car filled with equipment (and the stories of stalling the engine by hitting the transmit button were true!). One of their frequent problems was that a huge corona discharge would often leap off of the tip of the antenna, producing huge distortion on the signal. You would never want to see that inside of an apartment or your attic! Another issue is the electromagnetic field itself. There are valid concerns with the effects on human health of strong electromagnetic fields, including the possibility of causing cancer. The ARRL has a lot of good data on this subject and it's covered in all recent ARRL Handbooks. In any case, the fields produced by QRO operation with indoor/temporary antennas are likely to cause very serious problems with all other appliances including lights, radios, televisions (even battery powered portables), microwaves, computers - you name it. At QRO levels, if a device runs off of electricity it's likely to be severely affected by a nearby antenna!

[Elecraft] Elegant PSK interface (KPSK2)
Hi Everyone, I'm curious if anyone has considered building a PSK interface into their K2 with a couple audio jacks coming out the back of the K2 (e.g. where the transverter is supposed to go on my #3421)? What I'm thinking about is building an interface that ties into the K2 (bypassing the front mike connection) with a more sensitive VOX built in - and with line-level type audio input/output. My aim is to avoid the messy cable situation I currently have with my PC laptop where I must use a USB-serial adapter to key an outboard interface, and a bunch of audio cables. Instead, it will be similar to the Ten Tec Argonaut V - and only require two audio patch cords between my laptop and the radio - with the rig being keyed by the built-in interface, and audio levels being controlled only on the laptop. 73, Daniel AA0NI ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KPA800/1500 Power Question
Jim Harris wrote: Now my real question. Does anyone know what the AC power requirements are for both models. I'm bringing more power into my shack this summer and it would be great to know what power is required. I don't know the actual power requirements, Jim, but I would expect overall efficiency of around 50%, taking into account the power supply and amplifier efficiency. However, if you are installing ANY high power amplifier, it's generally thought that a 20-amp 240V circuit is appropriate. This is probably more than you will need for a KPA800, which would probably work fine with 15 or perhaps even 10 amp service at 240V, but (depending on the length of the line to your service entrance) it probably means no. 12 wire, which is not a big deal. An electrician can tell you what you need to do to meet code in terms of wire size, type of conduit, type of receptacles, etc. What I did was install 20 amp breakers and use no. 10 wire to ensure the minimum voltage drop under load. I brought out 4 wires: two hots, one neutral, and one ground. The neutral is ONLY connected to the ground at the service entrance, noplace else. Most amplifiers only need the two hot leads and ground (there are exceptions). I use the hot-to-neutral connections to provide two 120v circuits for other shack equipment. I would not run a 1KW amp on a 120v line if I could avoid it, due to the greater voltage drop that would be incurred. I understand that the KPA800 is capable of 1000w or more output on CW (it's limited to 800w on SSB due to increased IMD at higher power levels). -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Quoting K2VCO: Let's say you have a 1.5KW amplifier. Overall efficiency might be 50%, so it draws 3KW key down. What does it draw key-up? Now let's say you operate 2 hours a day, 5 days a week. During that time, you QSO 50% of the time. During a QSO, you transmit 50% of the time and listen 50% of the time. You use CW, so your duty cycle is 50%. This will cost you 3KW * 10h * 0.5 * 0.5 * 0.5 = 3.75KWH, or, at the specified rate, about 48 cents a week, or $25 a year if you always use the amplifier and don't take a vacation. Actually a bit more. If the amplifier draws, say, 250 W key up (to keep the heaters hot, fans turning, and B+ caps charged) then you have an additional 8.75 hours x .25 = about 2.2 kWH. So the weekly total is really more like 70 cents a week. Of course in most cases merely leaving a few lights on a few hours each day will use more kWH in the course of a year. SSB will be cheaper. How do you figure? The duty cycles are about the same. SSB may even have a higher duty cycle if you turn the processor on. btw, the duty cycle of CW is about 44%: Consider the standard word PARIS. With all the spaces, it's 50 time units long. But the key is down only 22 of those times. 73 de Jim, N2EY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

I can't speak to the ATU issue of poor efficiency on 10/12 meters since I don't have a KAT100. The droop on 30-15 meters from the KPA100 suggests an issue with the bandpass filters. The KPA100 typically exceeds 100 watts output quite easily. The fact that yours doesn't suggests low supply voltage or a measurement error that is showing a slightly low output across the board. Suggest you look very closely at your bandpass filter components for the low bands. The KPA100 manual also has a procedure for checking the bandpass filters using an antenna analyzer, if you have access to one. Just for the record, here's what my K2/100 delivers at full power into a dummy load: 160: 112 watts 80: 108 watts 60: 110 watts (legal limit on this band is 50 watts erp, of course) 40: 112 watts 30: 107 watts 20: 105 watts 18: 111 watts 15: 106 watts 12: 104 watts 10: 106 watts at 28 MHz, 46 watts at 29.5 MHz That roll-off at the upper limit of 10 meters is normal I believe. Of course the difference between 100 watts and 112 watts in what another Ham will hear on the air is completely insignificant, but it demonstrates that the KPA100 will meet the 100 watt transmit specification across the HF bands.

[Elecraft] KX1 30m module - Hand capacitance effect?
Hi. I noticed last night that if I am listening to 30m and I place my hand on the case of the KX1 (anywhere on the case but especially over the 30m module), that the signals get a bit quieter. I'm wondering if it's a capacitive effect since the 30m module components are separated from the case by only a thin rubber foot... I have 26ft wire connected as an antenna and about 15ft as a counterpoise. I wondered if the 30m module wasn't grounded properly but I don't suppose it would work at all if the ground wire was broken (mind you if I remember correctly there are two ground hookups - maybe one has given out). Can someone else with a KX1 confirm this behaviour? It doesn't happen on 20m/40m. Thanks, Martin. VA3SIE. ___ Yahoo!

The RF from a QRO amplifier won't likely kill you like touching the terminals behind the safety cover of a circuit-breaker box will, but if you get onto high voltage RF you may wish you were dead. The pain of serious RF burns is deep and long-lasting. Permanent nerve damage is not unusual. Once I was working with a guy installing a large, self-supporting antenna on a ship when he got a burn on his hand from induced RF from a nearby broadcast station. We were using a container crane to position the antenna for bolting to the ship. I was on the ship and he was riding the crane with the antenna. When he reached across to position to base so I could drop the bolts in place, I saw the glow of an RF arc between the brass antenna base and the ship. He let out a howl that would have done the Wolf-man proud. I later figured out that the 200-foot high container crane, grounded at its base on it's metal tracks to ensure workers are absolutely safe from electrical shock, formed a giant loop antenna with the ship sitting in salt water. We were only a few hundred meters from the broadcast towers. It made a black mark about two inches long on his palm in a fraction of a second. He was in such severe pain for several weeks that is was very difficult to use that hand at all. Remember, that was just the induced RF from a nearby antenna. No direct connection at all. Several hundred watts from a Ham rig can be at least as destructive if you touch it. Also, I've seen arcs 6 inches and longer erupt from high-impedance points of a kilowatt transmitter antenna system across a dirty insulator. They not only pose a serious injury hazard, they can and will start fires. Temporary or indoor antennas are no place for QRO power levels. Like all high voltages the voltages resulting from high RF power levels need not be dangerous or harmful if treated with respect. Good insulators, decent distance between people and the antenna, and good safety procedures when working around the equipment make a kilowatt no more dangerous than QRP.

A 15 foot 'counterpoise' isn't an especially effective ground, so adding your body capacity often has a significant effect. If you were running high power, you might complain that the rig 'bites' with RF when you touch it while transmitting. Those effects are very frequency-dependent, which is why you only notice it on one band.

Brian, With a window you could deploy a homemade version of the BW window loaded antenna. It was a whip as long as you dare, and a base loading coil, which you can wind and tap for various bands. Put a counterpoise wire for say 33 feet on ground side of feedpoint at base of coil. Tap up on coil with coax to find 5 0 ohm match. A jumper shorts out parts of coil for various bands. If the whip is 6 feet you will find collapsible ones at some radio outlets. 72, Stuart K5KVH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The K1 uses the same cabinet design with 2D fasteners...but with countersunk screws. Either way, I also really like the enclosure design.

With my TS-950S, except for getting the top cover off, I can't figure out how to access ANYTHING.

Martin, VA3SIE asked: I noticed last night that if I am listening to 30m and I place my hand on the case of the KX1 (anywhere on the case but especially over the 30m module), that the signals get a bit quieter. I'm wondering if it's a capacitive effect since the 30m module components are separated from the case by only a thin rubber foot... I have 26ft wire connected as an antenna and about 15ft as a counterpoise. I wondered if the 30m module wasn't grounded properly but I don't suppose it would work at all if the ground wire was broken (mind you if I remember correctly there are two ground hookups - maybe one has given out). Can someone else with a KX1 confirm this behaviour? It doesn't happen on 20m/40m. - I'd suspect you are detuning your antenna by touching the case. A 15 foot 'counterpoise' isn't an especially effective ground, so adding your body capacity often has a significant effect. If you were running high power, you might complain that the rig 'bites' with RF when you touch it while transmitting. Those effects are very frequency-dependent, which is why you only notice it on one band.

[Elecraft] K1 Problem with Power Out on 30/40m
Hi there, I have a problem with my K1-4 on 30/40m. First I have to say that it was working before and I don't know what happened. Here is what I know: - Power out on 15/20 is ok. - Power out on 30/40 is 0.1W, probably less - I am losing the signal between DRV (1.5Vpp) and PA (0.1Vpp). Measured with Oscilloscope. - To be precise the signal is present at the base of Q7, but is extremely weak at the collector. - I checked Relays K7 and K8 manually. They work. - I checked T4. Ok. - I have a dummy load attached. Measured 50Ohms. - I checked L4-L6. 0Ohms. - Of course I checked solder joints/bridges What else can I do or check? What could be the problem? Thanks in advance!

Hi All, I think I have always liked it because it looks more military heavy duty with the round head screws. Reminds me of those what are they? ARC-5 receivers I think made of aluminum plate and plenty of screws. I honestly wouldn't like the K-2 styling one bit if it was put in a say a Kenwood TS-2000 like sleazy plastic case. Also I can't imagine the case with flat head screws. Alignment would need to be perfect or a sharp edge of a screw head would be exposed. I guess I just appreciate the practicality of the design of the entire shell. The screws are an integrated part of the design. I like it so much that I bought an EC-2 for my KAT10 and KPA100.

I have not noticed that effect. I have noticed that the VFO encoder is pretty noisy as you change frequencies on some bands but not others. Maybe you are getting encoder or synthesizer noise? Does the noise go away when the antenna is disconnected? Does the noise only happen when you change frequencies? Does the noise go away when you take the rig outside? Does it go away with a different counterpoise length? Mike KL7R When in danger, or in doubt, run in circles, scream and shout. -- Robert A. Heinlein __ Yahoo! Mail Mobile Take Yahoo! Mail with you!

[Elecraft] QRO in a QRP Society
A good point was raised in the KPA800/KPA1500 threads -- those in this community (probably many) who are accustomed to QRP power levels and have never messed around with QRO need to beware. We sure don't want any of our ham brothers/sisters hurt, and trust me, it does hurt (As a kid, I wasn't the fastest learner, but I did learn). I think the RF actually cooks your tissues and the effects take months to heal. And, it's always on your fingers ... those things you use the most. I would not consider an inside antenna with QRO power levels, and even at 100W, the voltages can be truly astounding. I once strung some bell wire around the living room of an apartment near the ceiling in a U-shape on push pins, and fed it with my S-line and a tuner. The end of the wire was at the top of the wood moulding around the sliding door that opened onto the patio. At first tune-up, a 2 RF arc jumped from the end of the wire to a drywall screw covered by paint screwed into the metal stud, and started the corner of the wood moulding on fire. Andrea and I were newly married. Everything you can possibly imagine about her reaction to this example of physics is both true, and also quite insufficient to describe the ensuing discussion about my radio habit, the safety of living with me, and how the kids we had yet to make might survive to adulthood with me in the house. Theoretically, the voltage at the un-fed end of an antenna is infinite, and Ohms law tells us the impedance is infinite too. Infinities don't really happen in our everyday world, but an impedance of perhaps 5,000 ohms on a lossy inside antenna is quite reasonable. 800 watts in 5K ohms yields 2KV at the end of the antenna.

RE: [Elecraft] S/N 5000
Not to beat the subject to death, but the K1 uses flush screws and there are absolutely no alignment problems or sharp edges. The workmanship on the K1 case is top quality. I can't imagine Elecraft accepting anything less. The K1 case goes together exactly the same way as the K2. Identical hardware. The panels are just smaller and the holes are properly countersunk. The reason the K2 has humongous, bulbous screw heads sticking out everywhere and the K1 doesn't has nothing to do with quality or design concerns. I believe Eric or Wayne said on here a few months ago that it is that way because they like it that way. Can't argue with that! I have both, a K1 and a K2. I've learned to accept things as they are. None of us are perfect. BTW, a few K2 owners who appreciate the MOMA-quality aesthetics of the K1 have countersunk the holes in their K2 panels and installed K1 screws.

(At Dayton, Eric advised me to contact Gary at the plant for help in nulling and calibrating the ATU, which I will do as soon as the dust settles from our return from the Hamvention). Great radio, Wayne $ Eric. Thanks for making my surgery recovery a whole lot less boring! vy 73 Rich K7SZ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] S/N 5000
Hi Eric, Sounds good. I need to look at the K1 case. Yes, bulbous or flat, what a difficult decision.

Re: [Elecraft] QRO precautions ??
Hello, I recently reactivated a Swan linear and an older Hallicrafter HT33A, When I exceeded about 500 watts on 40 or 80, the GFI breaker in the upstairs bathroom would trip and the electric bed also upstairs would start running. (A real No-No if the XYL was in it). I had a lot of bothersome RF in the shack from a 135' OCF antenna that didn't cause any problems at 100 watts. I also had a little TVI in the TV upstairs. Using an old linear, you miss QSK. However I solved all of these problems. On the GFI breaker, I replaced it; the new ones are RF resistant. I used an AC line filter I had in the shack and that fixed the electric bed problem. On the RF, I used all standard fixes: short grounds, better ground on the coax shield before coming into the shack. All helped but but it took a dozen or so turns of RG8X on a 2 gallon chlorix bottle where the coax came into the house to get rig of it completely. I installed two LPF filters in the coax from each linear to its tuner and that took care of the TVI. For QSK, I reactivated a QSK1500 external switching unit on the Swan and Omni-VI that gave me back QSK at anything less than 1500 watts.On the newer linears, some of them have QSK built in, so if you want QSK, buy a linear with it build in. I'm assuming the Elecraft linear has it. It goes without saying that you need heavy duty coax switches, RG8 or at least RG8X coax and even LMR-400 on long runs. You need high power antenna tuners, lightning arresters, heavy duty grounds and adequate power to the shack. I have a separate 220 v circuit going to the shack. Operating, you don't need a linear most of the time, especially on CW. Sometimes it's helpful on SSB particularity on 20, 40 and 80. Frankly, If I had to buy a new 3K linear (dollars), I'm not sure it would be worth it. You have to see what kind of operating you do. Of course, from Elecraft's point of view, if there are linears to be sold, a good, relatively inexpensive kit has a lot of potential. At 01:31 PM 5/26/2005, you wrote: With the possible eminent presentation of a VERY QRO amplifier to the Elecraft family, there is certain to be a number of us, with only QRP experience, jumping in and playing with gobs of RF energy for the very first time. Let's hear it from those with experience, some do's, don'ts and caveats that go along with running the legal limit. I hate learning stuff the hard way...
