RE: [Elecraft] Conception of a K2
John, Welcome to the Elecraft ranks. I know you will enjoy building the K2 and enjoy operating it even more. I built my K2 S/N in 1998 and have used it a lot, mostly portable. If you are even contemplating adding modules to it, get the rework eliminators. Some of the add-in modules require the removal of components. With the rework eliminators, those components go on plug-in boards that are "place holders" for the add-in modules, so when you are ready to install an add-in, you simply unplug the rework eliminator and plug in the add-in module. The parts to be removed are located on the rework eliminator.

Re: [Elecraft] Conception of a K2
John, I suggest that you obtain a good lamp with a magnifying glass attached. Mine has a round florescent lamp that fits around the lens. This provides plenty of light and the magnification really improves you productivity. I am not saying that the K2 is too small - just that time has taken a toll on my eyes!! Another item that may help is a vice to hold the circuit boards while you are installing components and soldering. I do not consider this as important as the magnifying lamp.

[Elecraft] NAQCC August Sprint
This Tuesday evening, the North American QRP CW Club will be holding its monthly sprint. Here are the particulars: Date and time: Wednesday, August 15th, 0030-0230 UTC (Remember that's Tuesday evening here in the USA) That's 8:30 - 10:30 EDT, 7:30 - 9:30 CDT, 6:30 - 8:30 MDT and 5:30 - 7:30 PDT. Bands - Frequencies: 80M - 3555-3565 kHz (Be courteous to FISTS operating on 3558 kHz) 40M - 7039-7050 kHz (Avoid W1AW on 7047.5 kHz). 20M - 14059-14065 kHz. General: A particular station may be worked once on each band. Operate CW only. All licensed amateurs are invited to participate, but only those operating QRP (5 watts or less) are eligible for awards. Call: CQ NA Exchange: RST - SPC (State Province or Country) - NAQCC Nr. (non-Members substitute power level for NAQCC Nr., e.g. 5W, 1W, etc. Be sure to add the W.) QSO Points: QSO with a Member, 2 points. QSO with a Non-member, 1 point. Multipliers: Each USA state Each VE province Each country except W/VE All multipliers count only once in the contest. Bonus: If you use only a straight key for the entire sprint, multiply your score by 2. If you use only a bug for the entire sprint, multiply your score by 1.5. If you key with anything other than a straight key or bug, there is no bonus multiplier. Categories: SWA - simple wire antennas - for those using a simple wire antenna per NAQCC definition. GAIN - gain antennas - for those using other than a simple wire antenna. Special Award: The purpose of having a special award is to perhaps award a certificate to someone who knows they can't win one of the regular 1st/2nd/TNW certificates, but would still like one of our beautiful NAQCC certificates to display in the shack.

[Elecraft] PWR control
Last weekend I used my K2 in combination with my own designed/build 44 Mc transvertor for meteor-scatter QSO's. Last week I finished my "audio interface / sequencer" to give me "isolation between PC and K2 / save my preamp when running a high power amplifier" respectively. The K2 has the K60XV option installed to give me a separate RX input and a low power IF drive (controllable by the front knob) on 28 Mc. The system worked well except one detail. The drive power was very unstable which causes the output to change between 250 - 1250 W (even walking around in the shack gave me these power changes). When TX-ing I had to adjust the power knob each period (30 sec). It happened many times that I increased the control knob but power goes went or vise-versa and jumped back again. I used RF-clamps to see if I could find a "hot spot" but it all looks like direct pick-up from the K2. It seems that the power control circuitry is rather HF sensitive (for 144 Mc). The power LED-bar of the K2 (S-meter) showed the change in power accordingly. Anybody else with this experience? And a remedy may be (to prevent re-inventing the wheel)? 73's, Evert PA2KW ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 saves me $100
Here's a benefit of a K2 I had not thought about. My Carvin power amp went "bad". OK, I killed it by running it in bridge mode while hooked to two speakers. Carvin wanted $120 flat rate to repair it. Instead I ordered 2 output transistors and, using the skills and tools left over from building the K2, installed the new transistors. The amp works fine. Parts cost me $12 including shipping. So instead of spending $120 for someone else to do it, I did it for $12. And this wasn't the first time I've save money because of the K2. The bass amp I donated to the local high school became intermittent. I found the issue (poor solder joint - imagine that) and fixed it. So there are benefits of having build a K2 that extend even beyond the realm of ham radio! - Keith N1AS - - K2 5411.ssb.100 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] ESSB- What About Pactor III?
I'm sure that will change now that it has been mentioned. As the elecraft community are largely builders and experimenters, the closed aspect of Pactor-III doesn't generate the interest that would otherwise drive the discussion. As a protocol, Pactor-III is trying to increase the throughput of a data transfer and it is reasonably successful under the right conditions. The usefulness versus the cost in bandwidth is another issue. The bigger problem is WinLink 2000 and how it is used. Proper amateur practice requires monitoring the signal to ensure you are not interfering with existing communication. The issue arrises from the WinLink operators who fire up radio connected to the computer and let it go. Frequently, they aren't even listening and WinLink cannot "hear" anything that isn't another WinLink end-point. Everything else is "noise" which WinLink addresses by retrying until it succeeds. Similarly, if the widebanders were only using their capability when they weren't impacting others, there wouldn't be the strong response. -- Clark B.

Many digimode enthusiasts do get annoyed about PACTOR robot stations. But mostly the digital modes each keep to different areas of the digital sub-band and there is not very much conflict - unless you're using some new mode somebody has just written a program for, in which case you aren't welcome anywhere. :) Excepting contests, there is not usually any trouble finding a clear frequency to operate on in the digital sub-bands. The number of phone users is probably orders of magnitude greater than the number of data users so the potential for trouble if a new wider band sort of phone catches on is far greater. -- Julian, G4ILO K2 s/n: 392 K3 s/n: ???

RE: [Elecraft] Is the K3 capable of ESSB?
These concerns about using excessive bandwidth are all certainly legitimate,
but history suggests that anyone seriously against using more
bandwidth/signal in crowded bands needs to take a different approach or
their concerns will not be heard.
The same sort of arguments I'm reading in this thread - efficient use of
spectrum - has come up before when a wide-band mode was proposed for 40
meters: a mode that would allow each station to use the bandwidth currently
used by four, five or even more signals currently on the band.
Editorials and letters ranted against the terrible waste, the destruction of
Amateur radio and ruination of a great Ham band if this new mode were
allowed.
Nonetheless, it was and the 40 meter AM 'phone' band segment opened in the
USA in the 1950's ending that band's 300 kHz of CW-only operation.
"Efficient" CW operators had to get out of the way. Their one consideration
was that they could, legally, operate in the phone segment while the phone
operators ("phony Hams" some called them back then) were restricted to their
sub-band.
Elecraft has taken what I think is a very conservative and reasonable
approach to providing ESSB capability. They have designed the K3 to limit
the ESSB signal to no more than 6 kHz. In one post some time ago, Wayne
mentioned that it would likely be "less" than 6 kHz. Some SSB operators may
feel that's too wide, but 6 kHz is used by double-sideband AM operators on
those bands today. So, for those who want to try ESSB, they won't be using
any more spectrum that the current crop of double-sideband AM operators.
Keep in mind that running ESSB is useless unless *both* stations in a QSO
are ESSB capable. The receiver in a conventional SSB rig simply cuts the
signal down to a normal SSB bandwidth. And the K3 will not run ESSB unless
the optional 6 kHz filter is purchased.
Anyone who has followed Elecraft over the years knows that they have been
very conscious about ensuring their transmitters are exceptionally clean,
meeting or exceeding both current regulations and the current practice for
signals on the Ham bands.
For those who are serious about preventing the use of ESSB on at least some
bands, history suggests that an argument other than "efficient use of the
spectrum" will be needed.
I operate CW 99% of the time. It's by far my favorite mode. I'm gratified to
note that bunches of CW ops do not "set up shop" in the middle of the phone
bands, even though they could do so legally to avoid the mayhem of a contest
or just because it might please them to do so. Traditionally, most Hams have
been considerate operators even if they don't agree with another's choice of
modes. That means doing the "right thing" even though one might disagree
intensely with others. I would hope that spirit continues.

[Elecraft] ESSB- What About Pactor III?
Everyone gets into such a high dudgeon about ESSB, but I see no one here complaining about PACTOR III, which is a proprietary mode which takes up the same bandwidth as a SSB signal, but is allowed in the "data" parts of the bands, INCLUDING 30M. Not only that, but it is employed by dozens of "robot" stations, whose purpose is to pass EMAIL on the Ham Bands. This is a lot more threat to the bands than a few experimenters playing with ESSB, since the ARRL is pushing the email forwarding, or "Winlink," as the "be all, end all" of Emergency Communications. And yes, you can probably run it with your K3. Just spring another $1000+ for a modem from SCS (a German Company) and you can get on the bandwagon. -- --- _____ / \ / \ / \ / \ / \ John L.

[Elecraft] KAT100 Question
I've looked at the online info for both the KAT100-1 and the KAT100-2 and I can't see what the difference is between them except larger enclosure. Is that (and maybe a cable connection or two) the only diff between the two? David King ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Yes, this should be doable when the KRX3 ships, although the field testers do not yet have KRX3s to test this scenario. You may be on your own to figure out the details of connecting the KRX3 secondary input coax to the ANT2 SO239. For example, if you didn't want to cut the plug off the KRX3 coax, you could wire a mating socket to the SO239. (Alternatively, you could install a BNC in the vacant AUX RF hole in the rear panel and use that for the KRX3 receive antenna instead of the SO239.) 73, Ed - W0YK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

If you live in a rural area there may not be many stations on the air within reach at that time. It might not be the same in a densely populated area, though. Unfortunately it's hard to make rules that allow something to be done only when it doesn't affect something else. Once you start to condone wide band modes on the LF and HF bands people will use them whether the bands are crowded or not. -- Julian, G4ILO K2 s/n: 392 K3 s/n: ???

Re: [Elecraft] KPA100 - Low Voltage output from High Voltage Bias Supply Circuit
Michael, Congratulations on finding the faulty diodes. The failed diodes indicate that you may have suffered a static surge of some type - disconnect those antennas when not in use. You have also confirmed that the MAX1406 at U8 is damaged - take it out and your KPA100 should work for you. If you do not have an immediate replacement for the MAX1406, remove it right now and the KPA100 will function as an amplifier just fine without it - of course the computer connection part of the AUX I/O will not function, but all else should work. 73, Don W3FPR Michael Haygood wrote: Don, I replaced D16 and D17 which fixed the HI CUR, HI REFL messages and lack of power control. However, I am still reading a low output voltage from the high voltage bias supply. When receiving, the high bias supply voltage at D1 cathode and R12/R11 is about 67 volts. I've further investigated the low voltage output from the high voltage bias supply as follows: 1. De-soldered the high bias voltage side of resistors R12 and R11, then remeasured the high bias output voltage - about 69 volts. I did this to ensure that nothing in the T/R circuit was draining the high voltage supply; resoldered R11/R12 back into the circuit. 2. Desoldered the D7 anode in the high voltage bias circuit, which connects to the VSS supply pin of the MAX1406 (RS232 Interface), then measured the high voltage bias output voltage at D1 cathode - measured 154 volts! Re-soldered the D7 anode back into the circuit and the high voltage bias supply dropped back down below 70 volts. The high voltage bias supply output should be between 90 and 150 volts. Is it possible that the MAX1406 is somehow draining this circuit? Seems strange that it would be because it cuts the output voltage more than 50% when the MAX1406 VSS is connected into the circuit. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
