Re: [Elecraft] OT GENERAC generators
This is an issue where systems engineering comes into play. I live in the Santa Cruz mountains, where we lose power for a few hours or a few days a few times a year. Causes include storms that drop limbs onto power lines, disruptions because sections of the grid are shut down to support fire fighting, or because line. So far, (8 years) we haven't encountered an earthquake, but that will set up longer outages and other issues. We heat and cook with propane and have no Air Conditioning -- our electrical loads are home appliances like refrigerators, lighting, home entertainment, computers, and well motors. I've moved everything but the well motors and big electrical loads (like a microwave) to one side of 120V, and can run it quite nicely from a Honda 2000i running in econo mode. That drinks very little petrol, and we let it rest when we're sleeping. Internet, local WiFi, and other crucial systems are backed up with batteries that are float charged with wall warts and can run for days. In my shack, everything but computers and power amps run on big batteries that are charged by solar. We have a much bigger 240V Honda that can handle the well motors and drinks a lot more gas. 90% of our outages are handled by the 2000i, and we fire up the big one only when we need more. The well has two pumps -- one that pulls water up 100 ft to the tank, and another that pressurizes the system. Our water tanks are a few tens of feet above the house and hold a lot of water, so we can go for a while without running the pressure motors and well pumps. Not a lot of pressure, but enough until we need to take a shower. Laundry can almost always wait. We haven't used A/C since we left Chicago in 2006. I suggest that anyone contemplating a generator do this sort of system engineering. 73, Jim K9YC __ 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

[Elecraft] Zerobeat issue
Was on 40 meters trying but unable to zerobeat a CW carrier with my K3, and noticed that the gradations in tone from this signal were not continuous but were in intervals.

Re: [Elecraft] Lost text decode on P3/SVGA
Hi Paul. First you have to make sure you have the lower area visible on the external monitor. If not, turn it on in the SVGA section of the P3 menu. Next, be sure that you can see decoded text on the K3 lower display. If not, turn it on by holding the CWT button and rotating the VFO B dial until it says ON. Then adjust the threshold accordingly with the VFO A dial. My threshold is on 3. And finally, if you are decoding RTTY make sure your DATA MD is AFSK A at 45 bps (not 75 bps). 73, Mike K2MK Paul VanOveren-3 wrote Some how I lost the text decode on the P3, can someone please tell me how to turn it back on?

[Elecraft] Lightning Damage at W3BW
Hi guys: Lesson learned! I should not be attempting remote ops to my station on Maryland's Eastern Shore during the summer months. We get lightning strikes, and I got creamed a couple weeks ago. Everything was hooked up, and I am now having to replace my Orion 2800 rotor, and repair or replace my Green Heron RT-21 rotor controller, my TopTen band decoder, my Alpha DAS band decoder and some PolyPhaser lightning protection gear at the tower. The PolyPhaser failed to protect the rotor, and the rotor and relay lines from the tower run 350 ft. to my house. I needed protection at both ends. I will be a long time coming back from this. Now for the Elecraft part of this long whine... The good news: The K3 and the KPA500 survived. The bad news: The KAT500 is not behaving. It is not going through its normal tuning cycle, and the one or two times it did, into a dummy load, it left all the SWR lights on. That is not normal. if the K3 shows SWR= 1.1, the KAT500 should show the same. I can connect to the KAT500 from the PC using the KAT500 utility program, and that is all normal. I loaded in the last set of good parameters. This made no difference. Anyone have any troubleshooting steps to suggest? And, my W2 Wattmeter is completely dead, no lights at all. Or only a brief flash of all the top line of yellow lights, and then nothing. I cannot talk to the W2 using the utility program. I have no idea if the directional coupler survived. Same question --- where do I begin? I will try to send both to Elecraft for repair, but if there is something simple I can do here, that would be great. Thanks for any help you can provide. 73 de Brian *Brian F.

[Elecraft] Best Way to Make a 1/4-Wave Reference Wire?
I'm fooling around with custom portable Vertical array antennas for portable and DXpedition use. I was wondering if anyone in our list Brain trust had a favorite way to cut wires to a (reasonably precise) 1/4-wave length. (Yes, I can measure and No I don't want to model, I want to field test and calibrate.) What I want to do is have an elevated vertical (say base at 8'-10'), and add a temporary 1/4-wave reference counterpoise wire with a 20-degree downward slope. Then, use this set-up to adjust whatever physical items I'm using for the vertical element to get a 1:1 match, calibrated to the radials length. I want to end-up with a balanced antenna that is resonant and does not require a tuner (given that I'll have some minor adjustments to fine-tune the antenna's match at different locations). So, theoretically, the vertical could be made of 6-inch diameter aluminum tubing (not likely in the field), insulated or non-insulated wire of any size, or whatever. I'm also curious about and I to be able to see what the differences are in the lengths of antennas based on what materials of different types and sizes that I use. Ideas??? Thanks. 72/73, Craig W.

Re: [Elecraft] Best Way to Make a 1/4-Wave Reference Wire?
Interesting project. My generalist, non-expert suggestion. There are many variables you must consider, not the least of which are the electrical properties of the components, such as the length, velocity factor, diameter, resistance in circular mils, inherent impedance and capacitance of any conductor or radiator, the effects of any dielectric present, capacitive and inductive coupling with other objects in the vicinity, and many other factors. I am a big fan of verticals, but I usually work in the other direction: I set the length of the vertical element, and adjust the length and angle of the radials to effect a good match, but, it sounds like you want a set, or multiple sets, of known radials as an ersatz control group, against which you will judge the effects of different vertical radiators. I suggest you consider and measure / record all the factors you can, and build a set of control radials for your experiments, and use them for each individual experiment, and see what happens. You cannot control or account for all factors, but unless you start someplace, you will go no place. Build a set of radials and use them as a reference, and see what you get... assess the data... regroup... re-formulate ... and determine what to do next. I suspect the guy to ask is Rudy Severns, N6LF, who is the guru of vertical antenna testing. Happy days, good luck.

I'm happy with my 4-band module. Works great. And added backlight yesterday: A very nice rig. A six-band module would be good if you wanted 80-40-30-20-15 and one other band. I've never operated QRP on 80, except PSK31 with the PSK-80. Usually too antenna challenged when portable for QRP on 80, and at home QRN is bad a good part of the time.

Re: [Elecraft] How reliable an internet connection is needed for A K3 remote to work well?
Mike, Think of it as tuning up on top of an existing QSO. You're using Google's bandwidth, but not in any way that supports Google. If lots of people tune up on top of Google, they have to address the unwanted traffic, or throw money at the problem (buy more bandwidth). Courtesy suggest that you can dial off a bit, and still tune just fine. A traceroute from my workstation goes through Verizon DSL, through Alter.net (belonged to MCI last I knew) and then to Google's network -- 11 hops through 3 networks. Pinging Google means I'm measuring the performance of ten routers, Google's web server, and the wires in between. So let's say I'm measuring loss between here and Google, and it's at Alter.net. I call them and say your network is dropping packets and they say can I have your customer number? If I call my provider (Verizon) they refer me to their SLA (Service Level Agreement). This is a consumer DSL line, so the SLA says provisioned casually which is internet-speak for we promise that it might work some of the time. If you're trying to figure out the performance of your connection (and diagnose/fix problems) you want to know what happens in the first few hops. You want near zero packet loss and low latency and jitter, and you can work with someone you pay if there is an issue. Beyond that, you can only hope. Speaking as someone who ran an ISP for a couple of decades, I'm most interested in the first router past my facility. Looking at the traceroute to Google, the 1st is my local router, 4th hop answers ping, the 5th doesn't respond to pings at all, and the 6th belongs to someone other than Verizon. I'd ping the 2nd or 4th. Does that help? 73 -- Lynn P.S. I'm not a big fan of Google, but the same applies to MSN/Microsoft, Yahoo!, or any other well-known site that is likely to be up at all times.

Re: [Elecraft] OT GENERAC generators
Clearly YMMV, and we're all trying to solve different problems. My gasoline generators were a constant maintenance hassle because the AC power was so reliable that they were very rarely used, and I was constantly cleaning varnish out of the fuel system. My loads were small enough that a portable (100 pound) propane tank was more than adequate. If you have an outage every couple of months, then you aren't going to have trouble with stale gas. Also, if you plan on siphoning fresh fuel from your car, make sure you can get past the anti-siphon baffle. My favorite solution for intermittent backup is at http://priups.com. Enough to make me think about buying a Prius. 73 -- Lynn On 7/26/2014 7:12 AM, Brian Alsop wrote: I suggest one look into the details of how propane is sold in your area before buying a propane fired generator.

Re: [Elecraft] Best Way to Make a 1/4-Wave Reference Wire?
Hi Craig, What you are describing is an antenna in the dipole class, an antenna with two poles. Similar to an inverted vee rotated by 225 degrees. The half wavelength for the sum of the two elements will determine the resonant frequency. The total length will be near the classic 468/MHz = length in feet. The easy way is to make the antenna a little longer, measure the resonant frequency with an antenna analyzer, then scale to the desired frequency, for example, for 14.05 MHz. 468 / 14.05 = 33.3' make each element 1/2 of 33.3' plus about a foot, or 17.5' each. Using an antenna analyzer, measure the resonant frequency, it should be close to 13.4 MHz. Divide the measured frequency by the desired frequency, for example 13.4 / 14.05 = 0.954. Multiply the start lengths by the ratio, 17.5 * 0.954 = 16.7' for each of the two lengths. The above antenna will require a current mode Balun, for example the Elecraft BL2. Also, when modeling the gain pattern, it has about a 3 dB front to back gain ratio. The front being the side with the horizontal wire. I hope this helps, John KN5L On 07/26/2014 08:27 AM, CRAIG W BEHRENS wrote: What I want to do is have an elevated vertical (say base at 8'-10'), and add a temporary 1/4-wave reference counterpoise wire with a 20-degree downward slope. __ 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] XV144 IF input levels and schematic manual Rev C April 2006
Those levels are the MAXIMUM drive that should be used with each corresponding jumper settings. Once the jumpers are set, the Input Attenuator pot can be adjusted to set the desired output power. If set for the +39 dBm input, the attenuator is inserted into the 28 MHz transmit path and the 28 MHz gain stage Q6 is bypassed. The +24 dBm setting bypasses both the attenuator and the Q6 stage. The 0 dBm setting inserts the Q6 gain stage and bypasses the attenuator. If one is concerned about heat from the 3 watt resistors in the attenuator, it is only a problem when the +39 dBm input level is selected. If one is using a K3 with the KXV3 (or KXV3A), set the jumpers for the 0 dBm max input, set the chosen K3 XVn PWR menu parameter to L 1.00 and set the XV144 JP1 to pins 1-2 and JP2 to pins 2-3 (for separate TX and RX coax on the 28 MHz IF). Then transmit with the K3 power set at 1 mW and adjust the XV144 Input Attenuator pot for 20 watts output. The K3 power knob will then control the drive to the XV144 and thus the desired output level. 73, Don W3FPR On 7/26/2014 11:21 AM, John Lawrence via Elecraft wrote: Hi Jim The version of the manual I have clearly shows on page 8 the three levels in mw and watts based on jumper settings.

Re: [Elecraft] OT GENERAC generators
While this is getting to be long, I think this excerpt from a generator manufacturer sums it up best. Generator set exercise Generator sets on continuous standby must be able to go from a cold start to being fully operational in a matter of seconds. This can impose a severe burden on engine parts. However, regular exercising keeps engine parts lubricated, prevents oxidation of electrical contacts, uses up fuel before it deteriorates, and, in general, helps provide reliable engine starting. Exercise the generator set at least once a month for a minimum of 30 min. loaded to no less than one-third of the nameplate rating. Periods of no-load operation should be held to a minimum because unburned fuel tends to accumulate in the exhaust system. Whenever possible, test the system with actual building loads in order to exercise the automatic transfer switches and verify performance under real-world conditions. If connecting to the normal load is not convenient for test purposes, the best engine performance and longevity will be obtained by connecting it to a load bank of at least one-third the nameplate rating. Be sure to return the generator control to AUTO at the conclusion of any maintenance.

Re: [Elecraft] Best Way to Make a 1/4-Wave Reference Wire?
Craig, OK, so you want to have an electrical quarterwave resonator and electrical quarterwave radials. I would suggest that you first cut two radials - make them a bit long and put them up at the height and slope that they will eventually be used. Connect these two radials as you would a dipole - then measure the resonant frequency. Adjust the length as needed to resonate at your desired frequency. Note that these wires being close to the ground will not conform to the usual cutting formula of 486/frequency in MHz, so start plenty long. Trim the same amount from each end to keep both radials the same length. You should now have 2 wires each an electrical quarterwave long in the position they are to be mounted. Once you have those two radials tuned - disconnect the one connected to the coax center conductor (leave the one connected to the coax braid). Connect the center conductor to the vertical radiator and adjust the radiator length for resonance. You will find this procedure in ON4UN's Low Band DXing book. He does use a buried radial field to adjust the length of the radiator, but I assume you do not have one of those handy. OK, you have the vertical and one radial tuned for certain - remove that radial and check that the other radial is also correctly tuned - adjust its length as needed. If you plan more than 2 radials, tune each of them (one at a time) to resonate with the previously tuned vertical. When all have been tuned, you may connect all the radials together. If you want a simplified process that yields essentially the same results (for practical purposes) - put up the vertical radiator cut to the normal formula. It may not be exactly a quarter wave, but it will be 'close enough' - yes it may produce something like a slightly off-center fed system, but it will not be so far off center to make much difference. Now connecting each radial (again one at a time) trim the length of the radial to make the resonance point at the frequency you desire. Disconnect that first one and continue with all the other radials planned. When finished with all of them, connect all the radials together. That is my standard procedure for tuning elevated radials. With elevated radials, only 2 are required to cancel the horizontally polarized radiation - if they are placed 180 degrees apart. 73, Don W3FPR On 7/26/2014 9:27 AM, CRAIG W BEHRENS wrote: I'm fooling around with custom portable Vertical array antennas for portable and DXpedition use.

(Yes, I can measure and No I don't want to model, I want to field test and calibrate.) What I want to do is have an elevated vertical (say base at 8'-10'), and add a temporary 1/4-wave reference counterpoise wire with a 20-degree downward slope. Then, use this set-up to adjust whatever physical items I'm using for the vertical element to get a 1:1 match, calibrated to the radials length. I want to end-up with a balanced antenna that is resonant and does not require a tuner (given that I'll have some minor adjustments to fine-tune the antenna's match at different locations). So, theoretically, the vertical could be made of 6-inch diameter aluminum tubing (not likely in the field), insulated or non-insulated wire of any size, or whatever. I'm also curious about and I to be able to see what the differences are in the lengths of antennas based on what materials of different types and sizes that I use. __ 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

Hi Fred, Question 1 is easy because you already guessed the answer. Question 2, not so easy. The available display resolutions for the P3 SVGA adapter can be seen in the SVGA manual. On a general note, a modern LCD monitor will be able to serve double (or triple) duty because they all seem to come with multiple inputs these days. If your PC has 2 or more video outputs you can set up the secondary monitor to run on its DVI or HDMI input from your PC. Then you can push a button (or toggle a menu function) on the secondary monitor to either display the P3 SVGA input or the DVI or HDMI input from the PC. That's what many of us do. But you would not use it for N1MM or some other critical application as you would need that full time on your primary monitor. You might put your VE7CC cluster program on the monitor shared with the P3. 73, Mike K2MK k6dgw wrote 1.

Re: [Elecraft] IF OUT question
Jorge, If you are talking about the K3 IF output, there is nothing to activate. Connect a known working receiver tuned to the K3 IF frequency of 8.215 MHz and you should be able to hear the same signals as the K3 is hearing - you may have to tune a couple kHz in either direction to find it, but the signal should be present. If you have a signal generator connected to the K3 input, the signal may be easier to find because it should be the only signal present. If you have an older K3 (prior to September 2009), you will likely want to add the IF Output Buffer Gain Modification which increases the signal level at the IF output by more than 10 dB.

[Elecraft] OT Thanks
Thanks to themany who responded tomy question about Generac generators. It is highly likely that wewill purchase awhole house model before next winter; sizeto be determined after consultation with my electrician. The best choice here in rural Nova Scotia is propane. Natural gas is not available and probably never will be. We already have a propane cook stove and it is wonderful. The generator will have its own tank.

[Elecraft] XV432 Demon Exorcism Operations
Hi Gang, I have an XV432 that is giving me fits. While my XV222 works FB with my K3/KXV3 combo, or any other IF rig for that matter, the XV432 has only worked well with my FT817 and 5W drive. While getting stuff together for the August UHF Contest, I now cannot even run the XV432 with the K3 because as soon as I select it, the radio locks up. The display is on but the buttons on the radio do nothing. The only remedy is to put the power cord from the radio and disconnect the I/O cable. Does not matter which of the 2 transverter ends on the cable I use. Again, the XV222 is FB and 432 won’t work. Some Googling turned up NT4RT who gave a paper at the 2012 SVHFS conference on a bunch of mods for the XV432 to make it work better. Lots of ground via connections, connector rework stuff and loads of changing signal paths by scraping solder mask and cutting traces. All very involved. I have the paper in my Evernote account and will share if you have not seen it, pending NT4RT’s approval. I’m not sure it he wants it to be “public”. My unit has the errata items performed along with an input filter at the TX1 connection described by a DL ham IIRC. So, here are my questions. 1. Is anyone using their K3 with the XV432 in original as-built condition with good success? No self oscillation or other issues? 2. What mods did you make to tame the demons, if any? I’m to the point where I need to decide: A. Fix this one which may take A LONG TIME. But that gives me a K3/XV222 and 432 for 6/222/432 in the rear position of my rover with one headphone, one key, yada yada. B. Ditch the XV432 and use my FT100D as my 6/222/432. This is a pain because running on 6 and 432 key 222. I’ve run into problems doing this and it really requires that the XV222 be turned OFF except when in use. I suppose I could build a switch that would power up the XV222 when I’ve selected the 28MHz band on the 100D. C: Build another XV432 and use the current one for spare parts. Your ideas are greatly welcome. -- 73, Mark K2QO __ 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] XV432 Demon Exorcism Operations
Mark, I cannot identify exactly with your problem statement (K3 locks up), but I can give you a few suggestions that may help if you are willing to experiment a bit. First of all, you can try putting a low pass filter between the XV432 and the K3 low power TX output. The one I use is a Mini-Circuits BLP-30+, but any LPF with a cutoff in the 30 to 36 MHz range should work just as well (it would not hurt to include in the coax to the other transverters as well if the IF cables are daisy-chained). The purpose is to eliminate any 432 MHz energy from getting back into the K3. Normally the symptoms are only that the transverter TX output is 'fooled' into thinking there is 28 MHz power when actually there is very little - but your symptoms seem to be more severe. It may be worth a try in any case. The 2nd is the power output module in the XV432 itself. That module was changed about 6 months (maybe a year, my memory for dates is short). The older module was an SAU82L and the new module is E600120 RA30H4047M1 High Power Module. The new metal shielded module prevents self oscillation as well as having much better linearity than the older module. My suspicion is that 432 MHz energy is getting back into your K3 and causing the difficulties. Check your XV432 output connector - it *must* be mounted with the flange on the outside of the rear panel. Also check that the paint has been removed from all the XV432 panels where they contact the 2D connectors. The is important for proper shielding of the XV432. While that is applicable to all the XVxxx series transverters, it is critical for the XV432. 73, Don W3FPR On 7/26/2014 8:15 PM, Mark Adams wrote: Hi Gang, I have an XV432 that is giving me fits.

[Elecraft] KX3 Menu options and defaults
I recently purchased a used KX3. I want to check the menus to see if anything has been changed by the previous owner. Is the menu list current in the online manual dated February 2013? I know that firmware updates have been issued since that manual was written. Thanks for any help! 73 Keith N8CEP __ 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
[Elecraft] Elecraft CW Net Announcement
Good Evening, Summer is back here in Oregon after a chilly, wet week. All the plants look well watered and the fire danger is low again. Many of the different types of berries are coming into season. This is a good time to find a black bear. Mountain lion sign is around now too. When I walk in the woods I kick up a few grouse, some California quail, and a deer now and then. Hopefully I won't disturb a mountain lion snoozing with her cubs. Propagation has been up and down but the sun has not been helping much. Some sunspots have come back around after their transit of the back side of the sun. Solar flux has been rising for the last few days too. Thirty meters has been open during the afternoon and evening. With the W1AW and DX stations there is a lot of activity on that band. Please join us tomorrow. 14050 kHz at 2200z Sunday (3 PM PDT Sunday) 7045 kHz at 0100z Monday (6 PM PDT Sunday) 73, Kevin.

Re: [Elecraft] OT GENERAC generators
That makes sense and I actually like to run with the house load on the gen. I have a manual transfer switch so I run about 5-minutes to allow engine to warm up before applying a load in test runs. Tend to be shorter if there is an actual power outage. 73, Ed - KL7UW At 11:29 AM 7/26/2014, Mel Farrer wrote: While this is getting to be long, I think this excerpt from a generator manufacturer sums it up best. Generator set exercise Generator sets on continuous standby must be able to go from a cold start to being fully operational in a matter of seconds. This can impose a severe burden on engine parts. However, regular exercising keeps engine parts lubricated, prevents oxidation of electrical contacts, uses up fuel before it deteriorates, and, in general, helps provide reliable engine starting. Exercise the generator set at least once a month for a minimum of 30 min. loaded to no less than one-third of the nameplate rating. Periods of no-load operation should be held to a minimum because unburned fuel tends to accumulate in the exhaust system. Whenever possible, test the system with actual building loads in order to exercise the automatic transfer switches and verify performance under real-world conditions. If connecting to the normal load is not convenient for test purposes, the best engine performance and longevity will be obtained by connecting it to a load bank of at least one-third the nameplate rating. Be sure to return the generator control to AUTO at the conclusion of any maintenance.

I know most just park their lawn mower over winter with gas in the tank. But an expensive gen set needs a little TLC to keep running well...like changing the oil and filters (oil and gas). We have enough outages that fuel is not stored longer than a few months (and I use stabilizer). 73, Ed - KL7UW http://www.kl7uw.com/http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: mailto:dubus...@gmail.comdubus...@gmail.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecrafthttp://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htmhttp://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net/http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.htmlhttp://www.qsl.net/donate.html Message delivered to mailto:farrerfo...@yahoo.comfarrerfo...@yahoo.com 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.com __ 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
