I'm getting this notation on my K3 3212 when powering up. The Manual says it
may be defective. If it is DEFECTIVE would this prevent the K3 Utility from working? How can I get a replacement? -- RC KC5WA <http://www.qsl.net/kc5wa> ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

My manual says the KIO3 may be defective, not the K3. Read the instructions there about operating without KIO3.

Tue night severe T'storms came through the Monroe, LA area. I lost my
computer the the Comcast link. After that is when the ERR IO3 made itself known. I'm sermising I receive a spike through the RS232 cable. Is this possible? My antenna were disconnected along with power. -- RC KC5WA <http://www.qsl.net/kc5wa> ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Here is all that I found:
I lost my computer Tues night through the Comcast cable link. When installing the K3 Utility in the new computer I found that it is not commuicating with the K3. I have ERR IO3 on K3 3212 on power up. The N1MM contest logger does not communicate with the K3 either. I surmise that the KIO3 is damaged Just contacted a station in OHIO and the K3 seems to be preforming properly.

Besides other grounding and lightning protection, which have been covered
very thoroughly here several times, I have a last line of protection on the RS-232 input to the K3. It's manufactured by (for?) Tripp-Lite and sold as a model DB9. I'm not suggesting that it replaces any other lightning or surge protection, but for $15 or so, it made me feel better. Amazon sells them (what a surprise!): http://www.amazon.com/Tripp-Lite-DB9-Protector-Suppressor/dp/B00006B81G/ref= sr_1_1?ie=UTF8&qid=1304176459&sr=8-1 or http://tinyurl.com/3d882eq . I also have them on my SteppIR controller, HAL DXP38, and Green Heron controller too. Some will probably say they are a waste of money, assuming you have a good protection system, but at $15 each, redundancy made sense to me.

In my experience, a wide variety of things is possible. For example,
last summer (2010) I lost one channel of my router (out of 4 in use) to a lightning strike, and my wife lost her entire computer (fried MoBo) to the same strike, even though she was unplugged from the mains...she was plugged into a CAT6 line from the router, but NOT the same channel that fried. The weird (interesting?) aspect to this is that the cable TV run that serves us is fiber optic up to the street entrance. This implicates the coax line from the street entrance to the house (buried at least 1' underground) and the house wiring itself. During this event, my computer was plugged into a plug strip and into the same router, but was turned 'off,' and a dozen or so pieces of ham gear were plugged into antennas and mains ('off' again), not one of which was damaged. This particular strike was perhaps 150 yards away at the end of the street. My tower is grounded through two No. 4 cables and 8 foot ground rods. As has been stressed on this list server, the effects of a near strike can be quite quixotic. I once got a good jolt (actually more of a strong 'tingle') when leaning against the metal frame of my garage door and a strike occurred across the street. Faraday's Law holds, but where? The equivalent circuits are not always obvious...time for more tinfoil hats...read the archives.

Yes...absolutely possible and in fact probable since your computer was taken out. Lightning > cable > computer > KIO3. This has been an ongoing problem with U1 on the KIO3 Main board and Eric has promised a mod to fix it but I haven't yet seen it appear. Here's how to check U1: http://mailman.qth.net/pipermail/elecraft/2011-April/148361.html If U1 measures bad, you likely need a new KIO3 Main board since U1 has finely spaced pins. 73, Bill P.S. Now I disconnect all RS-232 or USB ports in addition to all antennas and power. The last time this happened to me the problem was apparently induced by EM fields from a nearby strike. |

In 2005 lightning struck a tree across the street from our house, and traveled through the crown of the nearby trees and across our roof. Stuff that was damaged included a TV set, the sound chip from my son's laptop, my Mark V, my 2-meter radio, the microwave oven, and -- the control panel of our sprinkler system.

RC,
Yes, it does sound like you zapped the RS-232 interface in the K3 along with the computer. Contact with [hidden email] is in order - they can give you your options for getting it fixed. 73, Don W3FPR On 4/30/2011 9:55 AM, Robert 'RC' Conley wrote: > Here is all that I found: > I lost my computer Tues night through the Comcast cable link. > When installing the K3 Utility in the new computer I found that it is not > commuicating with the K3. > I have ERR IO3 on K3 3212 on power up. > The N1MM contest logger does not communicate with the K3 either. > I surmise that the KIO3 is damaged > Just contacted a station in OHIO and the K3 seems to be preforming properly. > RC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Is there a filter one could build into the connector shell ? or buy a
plug-in filter in an adaptor? David G3UNA > RC, > > Yes, it does sound like you zapped the RS-232 interface in the K3 along > with the computer.

alternatively, would the use of a usb->232 adapter instead of a direct rs232 connection help prevent this ? I wouldn't mind zapping a 15 EUR usb dongle.

Probably not.
As long as there's a conductor of any sort the strike energy will get passed along somewhere. All you'll be doing is sacrificing a USB-serial adapter and not saving anything. At my former QTH, out in the country, I was limited to dial-up Internet which meant modems. I lost at least 3 modems to nearby lightning strikes, one of which took the computer motherboard, all on-board Ram, the video card, and one of two hard drives with it. All of that was destroyed by the simple phone line connection. Nothing else in the house was destroyed so the surge didn't come in on the power connection. The lightning strike that did this mayhem was 200 yards away and blew up the maple tree it hit. It also induced a large surge in the phone lines hanging from the pole next to it.

So, complete and large-gap galvanic isolation is all that could save your
hardware, unless you know in time to remove the RS232 plug all together. Fibre optic coupling sounds favourite, not even a screened cable to conduct the energy.

1. Unless you have a shielded power line coming to your house, it's unlikely the lightning surge you describe would appear on the telephone line yet go "undetected" by the power lines.
2. The most probably cause of the damage you describe is that the power line ground / entry point, and the telephone line ground / entry point to your dwelling were not the same. I believe your modems (and the other PC hardware they were connected to) were destroyed by the _difference_ in the lightning-induced common mode voltages on the power lines and telephone lines at the point where they connected to your PCs. I, too, have suffered this kind of damage -- damage limited to those devices that are bridged across power and telephone lines. The solution is to bring both (or all) utilities into the house at the same entry point (and your antennas and control lines, too, of course), and to make sure the grounds of everything are tied together at that point. You want all your electronics equipment tied together in low-impedance fashion (at lightning frequencies -- i.e., in the 1+ MHz range) so that everything rises and falls together with the surge on the utility lines. Adding other protection (UPSs, surge suppressors, etc.) may be helpful but most of that stuff will be overwhelmed when the two utilities feeding your PC and modems are not surging in unison.

Mine come to me under the lake I'm on. But my phone lines used to come in at one end of my house, and the power lines at the other. They now come in right next to each other -- both still buried all the way. It cost me an excavation contractor to dig a trench for the phone company to move the telephone line to come in where my power cable entrance is, but after experiencing two separate $3000+ losses in earlier years, I figure the cost was well worth it. Now all utilities (AC power, landline telco, and satellite TV cables) enter the house within two feet of each other, and their grounds are tied together directly below the AC power meter. The grounds for all my feedlines and outdoor antenna control cables are at this point, also. The most expensive things in my shack (or maybe my entire house, now that I think about it) to replace are my K3 and my amplifier. The K3 and associated computer are fed off the same UPS, as are all accessories that have any connection to the K3 or amp (rotator control boxes, 12V DC supply for antenna switches, etc.). I use WiFi to connect all my PCs (but especially my radio computer) to the outside world (including my home printers). For my desktop PCs that don't have WiFi built in, I use inexpensive little NetGear USB WiFi adapters. I want no surprises from "sneak" wiring paths coming to my radio equipment. Most of my ethernet cabling that I installed ten years ago is currently unused. The amplifier isn't buffered from surges by a UPS. The best I can do there is my whole-house surge suppressor across my AC mains plus having all my grounds in the shack tied together plus having all my exterior wires and utilities grounded at the same entry point to the building. (Well, I could unplug the amp, I suppose.) Today only three things in my home "bridge" the power and phone lines: my fax machine (which I manually plug into the telephone line only when I'm sending or expecting a fax), the base station for my cordless telephone system, and my satellite TV receiver. The cordless base is inexpensive to replace, I wish my fax machine would blow up so I would have an excuse to get a decent one, and except for HGTV and Wipeout I wouldn't miss the satellite TV at all. We've had at least four major lightning storms come through this area in the past two weeks (probably more than we had all last summer!) and there were definitely some nearby hits (one second or less from flash to sound). Nothing seems to have skipped a beat here.
