[Elecraft] K2 S meter
I have an XG-1 and have calibrated my K2 accordingly. Sometimes, I run without the PREamp and this morning decided to see what effect that has on S meter readings so I could give more reasonable reports. I know a bunch of you have already done this but for what its worth: difference/correction (s units) 50uv signal PREamp on: S9 0 50uv signal PREamp off: S5 4 50uv signal ATTen on: S27 As a good contributor to the reflectors has often said, OK back in my cave! 73s, Jim, W4ATK K2 #4028 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] 48V, plus or minus, usually
It's that 50 volt 20 amp supply that's a killer! Actually, this voltage/current is very easy to come by, and relatively low in cost. The telephone industry uses this voltage and at high currents. Surplus is readily available, and often at prices less than the per-watt cost of a 13.8V high current supply. KS4VA often has such supplies at his commercial website www.valuesurplus.com ... he also sells new 1/2 Andrew hardline for 75 cents a foot!! (That's how I have an all-hardline feedline system installed here.) I have no commercial interest except to see a fellow ham with great deals do well! ;-) __ Do you Yahoo!? Yahoo!

[Elecraft] Re: Frustrated!

Hi Ed, Having built (and designed) many kits, I can empathize with your frustration at not being able to get part of it to work correctly. Please don't take a hammer to it quite yet -- it's really a great rig ;) The fact that it's working on the other bands means you're 99% there, and you really have successfully completed the kit. It sounds like you've tried all of the things I would try, initially, but here are some more recommendations: - The transmit mode signal-tracing procedure in Appendix E of the manual is very easy, and very effective at locating where the signal is disappearing. An easy to build RF probe is supplied with the kit. Chances are you can find out exactly where the signal is getting lost -- probably the band-pass or low-pass filters, but without tracing, you can't be sure. - If you build a simple test oscillator like that shown in Appendix E, you can inject a signal at the antenna jack, and trace it using the RF probe. To do this, switch to 20 or 30 meters, shut off the rig, then trace backwards with the RF probe starting at the antenna jack. My guess is that you have a short on the RF board in the 20/30-meter lowpass filter. Sometimes these shorts can be hard to find. If all else fails, please send the rig to Gary, our customer support engineer. He's seen just about everything, and I'm sure he can quickly fix it for you. If it turns out that the RF board was defective, the repair will be entirely on us. 73, Wayne, N6KR (principle designer of the K2) --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 Control Board U1 component number correct?
Hi folks - My K2 inventory lists Control Board component U1 as SA602AN. The actual part supplied is SA612AN. I assume this is a correct part but would like to verify before soldering to the board. I'd check with Elecraft support but it's the weekend - anybody know by chance?

[Elecraft] Atomic Clocks and Aluminum Siding
Atomic Clocks are great additions to the shack. But how, pray tell, does one get them to work inside a house with aluminum siding when you can't put it next to a window? I believe WWVB is on 80KHz, which is pretty low. Can one couple them to an antenna? thanks, dave belsley, w1euy ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] An amazing manual and building procedure
As I once again delve into building a K2 knowing little if anything about how they work I am again reminded of one of the truly amazing features of the K2 - the manaul(s) and building procedures. It takes a very together mind to create an assembly process that literally anyone can follow and even teach themselves to troubleshoot. The approach to kitting this radio is just as amazing as the capability of the resulting rig. Just had to say it once again! My compliments to Wayne, Eric, and I believe Lyle for such excellent manuals and organized building procedures! 73/Tim NZ7C ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Atomic Clocks and Aluminum Siding
Dave: From the 1 callsign, I expect that you are located in New England. If so, you're on the ragged edge of the normal coverage of WWVB. It is likely that the location is giving you as much trouble as the metal siding. Despite my 4 callsign, I am in New England (I live in Maine), and although my house is not metal-sided, my atomic clock (one of those solar powered MFJs with the big numbers) is located in the basement. What I have found is that the sync indication comes and goes. It often takes several days for the clock receiver to sync with WWVB. It will hold sync for a week or so at a time, but it occasionally drops out. However, I am in synch more often than not. The resulting time reading is surely accurate enough for most ham purposes. When you lose sync after having acquired it, the cock loses accuracy, but very slowly. When I listen to the NCDXF/IARU beacons, they are always start at the beginning of the second as indicated on my atomic clock even if it has temporarily lost sync. Personally, I would not recommend trying to modify the clock. In any case, before you start performing surgery on your clock, I offer a radical suggestion. Put the clock up in whatever position you want it to be for your ham operations, and just leave it. Do so for about a week. I suspect that there's enough signal leaking in through the door and window openings that the clock receiver will eventually (on the order of days) find the sync signal. If you cannot get it to come into sync within a week, then you probably do need an outdoor antenna. I'm sure that many participants in this reflector could come up with a practical way to build a 60 kHz external antenna and hook it to your clock. If I were doing it, I would look for one of the commercially made antennas that are designed for the time servers that some computer networks use. 73, Steve AA4AK At 11:03 PM 1/8/2005 -0500, you wrote: Atomic Clocks are great additions to the shack.

[Elecraft] Elecraft CW Net Announcement
Good Evening All, Another week in the new year has passed. We now have about 8 inches of snow with more on the way. Hopefully I can free the 40 meter dipole from the clutches of the fir tree overhead. It has drooped considerably under the snow load. I may have to shovel the roof once I am up there. But never fear I will attempt ECN/40. Hopefully the CME of Friday will have caused the ionosphere to awaken. But I do hope it has settled down a little after the jolt. The ladder line was supposed to peak out of the shack this week but other activities precluded that activity. Too much time in front of the computer and too little time outside. The snow is not helping things one bit. I hope to hear as many folks as I can tomorrow with the help of whomever can assist me. The East Coast was calling last week but I never heard you. I am sorry. Maybe one day I will become rich and put up a tower with a bigger RF catcher. One can always hope :) Please join us : Monday z (Sunday 4pm PST) 14050 kHz Monday 0300z (Sunday 7pm PST) 7045 kHz Visit our web site: http://ecn.visionseer.com/ for further details.

Re: [Elecraft] Atomic Clocks and Aluminum Siding
Why not just use a cheap GPS receiver instead of a WWVB receiver. It should work anywhere in the world, and give time keeping accuracy better than 1 microsecond relative to UTC. Most of the time location accuracy is around 10-30 meters, so equivalently the time error at a GPS receiver is 35 to 105 nanoseconds or so relative to GPS time that is maintained to within 100 nanoseconds of UTC. If you want to see the past week's relative error, try http://tycho.usno.navy.mil/gpstt.html. The Sprint PCS and Verizon networks, and probably others, are synchronized to GPS as well, but I have no source for the time keeping accuracy produced by your connected wireless phone.
