[Elecraft] T1 ATU Battery storage tip
This last weekend I finished construction on my T1 auto-tuner. The manual recommends that for transport that you reverse the battery in the storage compartment. I tried that and was not real comfortable with hearing the battery flop around as I walked around with the T1 in my fanny pack. I have inserted a small strip 1" of magnetic tape with an adhesive backing into the battery compartment. So far it does not seem to have any adverse effect on the T1's performance. The magnetic tape is the type you can find in small rolls at any hobby or craft shop. For what it is worth I figured I would pass on the tip. 73, KI4DGH Chuck Gehring ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I'll get the XG2. My understanding of the peaking is, you're using antenna noise to do the peaking, so by definition a good peak means it's more sensitive on receive. So, "weak on receive" must mean in comparison to something else. For me, the something else was an FT-817, which hears stuff the KX1 doesn't. Breaking news, it's got a pre-amp, and I understand has a pretty hot little receiver. I don't think the KX1's receiver is going to make anyone give up their full-sized modern rig for receiver duty. I think the KX1 is a "milder" receiver, which means you're more likely to hear the folks who can hear you too. I think the proper way to go about this is to look up the specs on the KX1 and see how many uVolts this thing is supposed to be able to pick up in the different bands, then using a signal generator or XG2 etc., see if your KX1 performs to spec. You have me interested in doing this also, and I have my KX1 #2 (sold the first one, sadly) coming in the mail any day now. 73 de Alex NS6Y PS - Prior proper preparation prevents piss-poor performance!

RE: [Elecraft] S meter question
Ken, I usully use the XG1 and check the S-meter with the preamp off on 40 meters - if the AGC Threshold is set for optimum receiver performance, and CAL S Hi and Lo are set the S-meter usually comes right in at S-9 with the preamp off. Yes, the manual is non-committal on this point, so I take that as an indication that either way may be right, the S-meter is not an absolute device, the point for S-9 varies all over the place from one receiver manufacturer to another anyway, so other than being useful as a relative measurement, I personally don't worry about the absolute calibration, but I set it as close as possible for other's K2s that I work on. In other words, do what suits you best. 73, Don W3FPR > -Original Message- > > I found the XG2 manual and the K2 manual a bit ambiguous on the > issue of weather to do CAL S-Lo and S-Hi with the preamp on > or off. > > I guess that it's a bit of YMMV but I've found if I set the S meter > with the preamp on, then I get no background signal above 20m. > > OTOH, If I do it with the preamp off, then the S meter seems too > "hot" below 30m.

RE: [Elecraft] S meter question
Ken, KG0WX asked: I found the XG2 manual and the K2 manual a bit ambiguous on the issue of weather to do CAL S-Lo and S-Hi with the preamp on or off. I guess that it's a bit of YMMV but I've found if I set the S meter with the preamp on, then I get no background signal above 20m. OTOH, If I do it with the preamp off, then the S meter seems too "hot" below 30m. I suppose that is a hint not to run the preamp below 30m? Help? - The preamp is only needed only under certain circumstances. It is there to ensure you have adequate input to the receiver to overcome the internal noise so your weak signal capability isn't limited by the K2. Tune to a spot where there's no signals, just normal background QRN. Set your filters for the narrowest bandwidth you ever use. Turn off the preamp and adjust the volume to hear the background QRN. Remove the antenna. If the noise level dropped when your removed the antenna, the weak-signal capability of your K2 is limited entirely by external noise, not internal receiver noise. The preamplifier is not needed. Using the preamplifier on bands where it is not needed increases the volume of signals but it also compromises the dynamic range of the K2. The K2 has excellent dynamic range, so you can generally get away with using it and never suffer any negative consequences, but it's not needed. Still, it's best to use the AF gain to control the volume in your phones or speaker. With normal Ham antennas you'll likely never need the preamp below 20 meters, and even 20 may not benefit from it. Very low gain antennas such as small loops, etc., that you might use for a separate receive antenna may benefit from using the preamplifier on lower frequencies while some excellent antennas may eliminate the need for the preamp even on bands above 20 meters. At the other extreme, you may be better off with the attenuator switched in on the nosier, lower frequency bands such as 160 or 80 meters. The "S-Meter" gives you a visual display of relative variations in signal strength. Trying to use it to measure a specific voltage at your antenna is an exercise in futility. It can do that under specific circumstances if you adjust your S-meter using something like the XG signal generators, but that's not its main purpose and, as you've discovered, it can be frustrating. If you hear a faint, just barely perceptible signal, it's S-1. If you hear a signal you judge to be extremely strong, it's S-9. If the S-meter doesn't agree, it's the S-meter that's out of calibration . When a company manufactures something like a receiver, it's necessary to run a series of tests before the finished product is shipped to be sure everything is adjusted and working as expected. For "communications receivers" having an S-meter, that meant that some sort of simple, "go, no-go" alignment and test was required. Various companies adopted an arbitrary standard signal level to feed into the receiver which the technician would use to set the S-meter to a reading of S-9. Collins, among others, adopted 50 uV for this signal level. It's a purely arbitrary level and is essentially meaningless in general use. The XG2 and XG3 generators let you do the same with your K2. It doesn't really matter if the preamplifier is on or off. It only matters that the meter agrees with your ears .

RE: [Elecraft] Airships...
You may get your chance to haul your KX1 or even a K2 aboard a dirigible yet. Friedrichshafen, where Count von Zeppelin built his famous airships from the LZ 1 that flew in 1900 to the huge Hindenburg in the 1930's is once again producing dirigibles. The company, Zeppelin Luftschifftechnik, is currently focusing on dirigibles for tourism, but plans include airships for long international flights after gaining the necessary regulatory approvals. The prototype Zeppelin NT has an aluminum and carbon-fiber skeleton that is lighter than the Zeppelins of the past, and a skin of Tedlar foil and polyester fabric that is lighter, stronger, and more water resistant than the cotton-based fabrics of the old airships. I haven't kept up with all the latest from Friedrichshafen, but I recall a news article that a Zeppelin was purchased by DeBeers to use for diamond exploration work in South Africa. Their website is http://www.zeppelin-nt.com/index.htm After working years in which my job entailed being regularly jammed into an aluminum cigar and launched through the air on trips that often lasted 10 or 15 hours, the image of traveling on a Zeppelin at a leisurely pace that allows my internal clock to keep up with the sun is mighty appealing. It's sort of like the difference between making a cell phone call and working friend on CW. Each has its place, even if one is "old technology". Implemented using modern materials and engineering, it can give the "old technology" new life - sort of like Elecraft does for "radio communications" Ron AC7AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Airships...
You all can fly in a modern-day Zeppelin, if you go to Friedrichshafen, the home of the original Zeppelins and the biggest European hamfest. Tourist flights are available, and the airship is very interesting technically. And the ride is very smooth and quiet. http://www.zeppelinflug.de/pages/E/diedzr.htm 73, doug ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] S meter question
I found the XG2 manual and the K2 manual a bit ambiguous on the issue of weather to do CAL S-Lo and S-Hi with the preamp on or off. I guess that it's a bit of YMMV but I've found if I set the S meter with the preamp on, then I get no background signal above 20m. OTOH, If I do it with the preamp off, then the S meter seems too "hot" below 30m. I suppose that is a hint not to run the preamp below 30m?

Re: [Elecraft] Blimp
I can relate to porpoising in a blimp. Friends of mine were volunteer pilots of the Fujifilm blimp, and I got to fly it twice. There's a yoke control for pitch and rudder steering, and to keep it flying level, you are always moving the yoke slowly--often to full extremes--to counter the natural unstable wanderings of the nose in two axes. Even without any boost, moving the garage-door-size elevators and rudders at the 26-knot cruising speed was not difficult, but it sure isn't anything like flying an airplane. The British AKS-600 Fujifilm blimp was the largest blimp ever manufactured, and the company is out of business now. --Dave Martin, W6KOW, K2 05120 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I can imagine 160 meter (or any other band) aeronautical mobile, but remember, it is the operating flight captain's decision as to whether you or I can deploy an antenna, or operate a radio from an aircraft or airship. His decision will be strongly influenced by ICAO and FAA directives on this matter, and company policy. Since I can't even turn on my cell phone until past international security when arriving in another country, I doubt that you will get approval to turn on an amateur band transmitter while looking downward from above.

[Elecraft] FYI RS232 Connectors (was serial port remote control)
Don et al, For my previous job, I had copies of all of the EIA and RS specifications for serial interfaces. The original RS232 specs call for the 25 pin connector (DB25). The current version (-E or -F I think) also introduces the high density 26 connector (looks like SCSI-2, but that's whole other set of specifications!). The DE9 was standardized in EIA-574, and I think originally appeared in the IBM PC-XT or some other early version. The 8 position modular plug is specified in EIA-561. RJ45 is the common name, but that designation is really only for a specific application and wiring pinout, and since we're using the proper names for the D-Sub connectors, well... RS232 is one of the few specifications to actually define mechanical (connector), electrical (voltage levels etc) and functional (TXD, RXD, RTS etc) parameters. The DB25 also appears in RS530, which is a mechanical/functional spec only, the electrical spec can be RS422 (a balanced interface) or V.35 (balanced data and timing, unbalanced control), or any other signal you want. I can't remember if 561 and 574 are also complete specs, but I think they are. 73, Dave AA3EE >From: Don Wilhelm <[EMAIL PROTECTED]> >Date: Mon Mar 27 16:10:46 CST 2006 >To: [EMAIL PROTECTED], elecraft@mailman.qth.net >Subject: RE: [Elecraft] serial port remote control of K2 question >This question gives me cause to post my occasional RANT for the protection >of your K2. > >CAUTION!

[Elecraft] Airships...
The US Navy had a number of disaterous episodes with LTA vehicles (USS Macon & USS Akron) and they were using helium. Too bad the US and Germany were at odds, the combined engineering skills might have left us with a more elegant means of travel. All the accounts I've read of the Graf or Hindenburg have them as the prefered means to travel the Atlantic (if you could afford it). It's amazing how the Hindenburg (perhaps the Nazi ties) has killed the airship travel industry for decades, even tho' the lose of life in HTA vehicles was, even at that time, much higher. There is a move in Europe to reintroduce tourist flights on these elegant airships, hopefully it will catch on. I'd jump on the opportunity to fly in one. Of course, I'd love to fly a Saturn V as well ;o) One may be possible some day soon... Can you imagine 160M Air Mobile? Cheers, Julius n2wn --- I suspect that airships, like Morse code, "shortwave" radio and a lot of other technology some folks assume are obsolete will be with us for a long, long time yet.

RE: [Elecraft] serial port remote control of K2 question
Nick, That is the implementation I have chosen for protection against accidents, YMMV. The hardest part of accomplishing that is removing the male #4 pin from the mating connector. Actually I can understand little advantage in using a non-conductor, a chunk of wire works fine too, but certainly a toothpick works just as well. For those who do not understand Nick's comment, this is one method of keying the AUX IO connector on the K2 - simply put a block in pin 4 of the connector mounted on the K2 (or KPA100) and remove pin #4 from the mating connector. This prevents plugging in a cable with an unmodified connector. There are other methods of accomplishing the keying that involve modifying the connector shell - cut a notch in the male connector and solder a projecting wire on the female. 73, Don W3FPR > -Original Message- > > > Don Wilhelm wrote: > > CAUTION!
