Re: [Elecraft] KSB2 P1 Wiring Questions
There is a new item from MFJ that people may find helpful when interfacing a mic to the K2. Its an MFJ-655 mic equalizer/conditioner/preamp that is supposed to interface any mic to just about any rig. It takes two types of mic connectors and the jumpering is done in the MFJ-655. You can use the standard setup with 2 pin jumper blocks in the K2 and not have to make any changes there. I don't have one but I think I will buy it soon. Read about it on the MFJ website. 73, Harvey KN6VP - Original Message - From: "Don Wilhelm" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; Sent: Tuesday, April 04, 2006 7:26 PM Subject: RE: [Elecraft] KSB2 P1 Wiring Questions Folks, My advice on mic wiring - unless you must use the mics with multiple rigs, wire the mic configuration header for the Elecraft mics, and then change the wiring at the mic plug to match the Elecraft configuration.

However, on p. 18 under Kenwood mics, there's a note: "Do not connect pin 5 unless mic has internal preamp," and another, "Leave pin 6 of the mic unconnected." I plead ignorance--does the MC-60 have an internal preamp? If it does, according to the manual I should connect signal pin 6 to mic pin 5. 2) I've read a posting that mentions leaving the bottom slide switch on the MC-60 "off." Done. Wonder if this negates the warning listed above and I should just leave signal pin 6 ("5V") unconnected? 3) The MC-60 has two impedance settings, 50K and 500--is there a preferred setting with the K2? 4) Any suggestions for wiring an 8-pin female mic plug from the RS 33-1187 that'll be compatible with Kenwood P1 settings?

[Elecraft] Confessions of an idiot
Or the subject line could be why good house cleaning is a must. On Saturday I posted a message concerning my KAT100-2 not achieving a good SWR. I had the bottom off all weekend, reflowing solder, re-calibrating the SWR bridge. Pulling my head out. Two kind souls responded to my post, but neither offered the correct solution path. Even The Gary didn't point me to the correct path. Man last night I was depressed. And then I found it. I'm not an electronics guy, but I can play "Wayne Says" pretty good. Where I was building the stuff was on a birds eye maple table that normally hosts the Drake C-Line. I removed the C-Line and put a canvas cover over it to protect the table. When tinning toroids cr*p falls down. A miniscule piece, perhaps a 1/16 x 1/8 somehow got on the top of the board and was shorting C22. (Sorry don't know the metric for the VE/rest of the world.) Pull out the pick and remove it and the KAT100 was dead on. And I was looking on the bottom of the board not the top. It wasn't until I brought out the DVM and magnifiying glass to look at resistances across the toroids from the top that I discovered it. My confession will most likely cause my old pal WD9DHI to give me grief at the Cedarburg fest, well so be it. But if it helps one other person to avoid my angst it would be worth it. Bottom line - check both sides of the board. And stay clean. 73, Joe N9JR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2IO and BeaconSee
Sverre I used to run BeaconSee very successfully with my K2 and it's KIO2. It did switch the K2 to the various frequencies without a problem. Note the following from my post on the subject some time ago: There is a little trick to driving the K2 that might not be obvious... if you don't instruct the K2 to use VFO A, then issue a frequency for VFO A (expecting the K2 to change to that frequency), it will only do so if VFO A is currently in use. This gives the appearance of an intermittent fault. The syntax that works correctly is to command the frequency by the following string: FR0;FA0001410; FR0 selects VFO A, FA000xxx tells VFO A what frequency to select. To use VFO B, issue the command: FR1;FB0001410; Depending on application, issuing K20;AI0; ahead of the commands may avoid confusion and doesn't do any harm. Note there are no spaces between commands in the string. The above works well with BeaconSee, the default "Kenwood" setting sometimes worked but lacked the VFO A/B command so could foul up if you had previously used VFO B. Just rename the Menu Label in BeaconSee to &Elecraft. 73 Dave, G4AON ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

On Sunday morning I stood up very urly to get some DX on 40m band but even there had no luck. But OK... after several tries I have been very glad to work WA8REI with his only 500 milliWatts on the 20m band; explained the rules of EQP to UA1AJ so I could log him too on the 20m band. A short while before the end of the party the 15m band was really open, I could listen a lot of Sout American stations loud and clear and worked N3DRK on 15m for EQP. But ok -- I think this year's EQP took place really in a "valley" of propagation conditions so things may only get better next year. Again N3DRK and others helped to stay up while chatting on the elecraft IRC channel. Next year I hope to be qrv with 100 Watts out of the KPA100 so that more stations may hear my signal.

Very true, but compared against WWVB and GPS, WWV/WWVH/CHU reception achieves the poorest accuracy as a time and frequency reference due to the inherent variability of ionospheric propagation. NIST claims WWV/WWVH time reception to be accurate to within 1 to 20 ms. WWVB reception is accurate to within 0.1 to 15 ms. NIST's Frequency Measurement and Analysis Service, which is GPS-based, is accurate to within 20 nanoseconds. This precision is due in part to the fact that NIST itself monitors the GPS signals while FMAS measurements are made, and so the readings taken are, in fact, traceable to NIST's atomic standards. Obviously, this is well beyond the accuracy most hams need in their shacks, but modern soundcard based weak signal and SSTV modes are demonstrating very clearly the increasing importance of being able to send and receive highly accurate, stable, and well timed signals. I suspect that trend will continue. 73, de John, KD2BD Visit John on the Web at: http://kd2bd.ham.org/ . . . . __ Do You Yahoo!? Tired of spam? Yahoo!

The frame averaging and the "sanity checks" that take place in firmware take several minutes _under good reception conditions_ to complete. WWVB reception quality normally improves at night due to better D layer signal propagation (and naturally lower noise levels). While every amateur text I've come across states that the D and E layers disappear at night, they, in fact, do not. They rise to higher altitudes and remain ionized through background cosmic radiation. It is this lightly ionized D-layer that makes LF reception possible beyond the normal range of surface wave propagation at night. Oddly enough, I have my K2/100 building experience to thank for discovering this. 73, de John, KD2BD Visit John on the Web at: http://kd2bd.ham.org/ . . . . __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [Elecraft] K2, LP-100 and HRD etc
The LP-100 Plot software does this already if you use DXlabs Commander (freeware) or TRX-Manager. It doesn't matter what rig is selected, it will work with any supported rig. You set the start and stop frequencies and step size, then hit Run. The program controls the rig and gathers the data. You can select the parameters to plot either before or after running, and save the plots to a file in CSV format for later recall or export to a spreadsheet. It may be possible to add HRD, but I don't see a linking component for them that accepts all the incoming commands needed. You can see a screen capture of the LP-100 Plot software at www.telepostinc.com/lp100.html, along with a comparison to a couple of antenna analyzers I own as well as my HP87510A VNA. 73, Larry N8LP Mike Walkington wrote: All, It seems to me that is should be possible to write a piece of software that controls the K2 transmit frequency (steps it up in increments), reads the LP-100 SWR, power etc, and produces plots for each ham band of frequency versus SWR, power etc. It would sure be nice if this was built into HRD.

Michael N9BDF wrote: I know that this issue comes up from time to time. I ran across this comparison of materials on the Web and thought some might find it useful. www.qrp.pops.net/w7el.htm --- Interesting info! The Elecraft kits are designed to avoid the need to attach the toroids to the PCB with any sort of material other than the leads themselves. Doing so may disturb the properties of the coil and reduce performance or cause the unit failure altogether. The kits are also designed so that the leads from the toroids will drop in to the proper pads *if* they are wound exactly as shown in the manuals (turns going in the directions shown, spaced as shown, and so on). In some cases it is essential the windings be positioned exactly as shown for the unit to work. In the KXB3080, for example, two inductors consist of a pair of windings side-by-side on a single toroidal core. On 80 meters a relay connects the windings together to form a larger inductance. If those windings are not wound as shown in the drawings and photographs, the inductances may not add causing the rig to fail to operate. Often there's a lot more to a coil than what meets the casual eye. That's why there are so many pictures showing them wound exactly as they need to be in the manuals.

Re: [Elecraft] WWV Clocks -- It's really WWVB
Twice a year, I take my clocks out to the back porch and out of my shack/office. That is around the time of DST/ST switches. The rest of the year, my "Atomic Clock" from LaCrosse is always in perfect sync to the ability of my eye to detect. I always do it after the switch because I never remember to do it before the switch!. In central NJ, FN20rg, in eight years of owning this clock, I have never once had this procedure fail: back porch with full western exposure, one night, the clock resets and from then until the next change over, it keeps great time. After acquisition, it seems to do some kind of matched filtering for "what it expects" to stay synchronized and gets better Eb/N0 performance as a result. I have repeated this every time I need to replace a battery or change ST/DST. Bob N4HY John Magliacane wrote: Hi Craig. We have a total of 8 "automatic" WWV synched clocks of various types...

Despite your short distance to WWVB, you still might be experiencing poor reception due to local interference sources. Computer monitors, switching power supplies, AC operated motors, and thunderstorms tend to generate a lot of 60 kHz noise. All three NIST stations transmit DST, leap year, UT1, and leap second information bits. With regard to DST flags transmitted by WWVB, NIST Publication 432 states: "Daylight saving time (DST) and standard time (ST) information is transmitted at seconds 57 and 58. When ST is in effect, bits 57 and 58 are set to 0. When DST is in effect, bits 57 and 58 are set to 1. On the day of a change from ST to DST bit 57 changes from 0 to 1 at UTC, and bit 58 changes from 0 to 1 exactly 24 hours later. On the day of a change from DST back to ST bit 57 changes from 1 to 0 at UTC, and bit 58 changes from 1 to 0 exactly 24 hours later." With this in mind, poor or inconsistant reception might explain some of the effects you've recently seen. I'm 1622 miles east of WWVB and own a WWVB-based frequency standard / UTC clock of my own design.

[Elecraft] 24-hour UTC Station Clock.
When I got back into the hobby last fall I needed a clock. I looked at some fancy ones but ended up buying a radio shack travel alarm clock. It displays 24 hour time, is easy to read & set and even has a thermometer built in so I can see temps like 58F at the operating position. I think it cost less than $20 - I don't recall. It is one of those great little accessories that I'm really glad I bought.

[Elecraft] MFJ clock (was Interesting tidbit..)
> ...an MFJ clock ... > Kinda stupid for an > Amateur Radio product. Model MFJ-123. Sums it up for me right there. I bought one of their "Deluxe Iambic Paddles" last year when I built my K1. It uses a split post to cinch down on the threaded contacts. Problem is that it's not possible to cinch them down tight enough to really hold the contacts in place, so you end up having to adjust the contacts between every exchange. I sent it in for repair/replacement under warranty and they sent me a new one. It has the same problem. It's a design flaw, not a problem with the individual product. I bought a March R-3a at Dayton last year (http://www.qsl.net/k4qu/). I realize there's a significant price difference between the two but given that the MFJ is a paperweight and the March is a keyer paddle, the issue for me isn't price, it's the product's ability to perform in the function for which it was designed.

Impossible to say, without defining "it". If "it" is: "timestamp is 6 monotonically ascending integers when displayed backwards* modulo 100", it will happen next year at 02:03:04:05:06:07. If "it" is: "timestamp is the first 6 integers in order when displayed backwards* modulo 100", it will happen in 100 years, as Earl suggests. If "it" is: "timestamp is the first 6 integers in order when displayed modulo 100", it will happen in 2101 just after 5AM. (01:02:03:04:05:06). * Backwards, LSD to MSD: ssmmhhDDMMYY.
