Re: [Elecraft] 6 meter RTTY Oink oink...
I'm a bit behind reading the digest so bear with me. I would recommend trying several of the WSJT digital modes. JT65a is designed for eme but JT6m was designed specifically for 6m. Look around 50.200 for digital modes and specifically 6m-eme. FSK441a is the meteor scatter mode (50.560). To find activity check into one of the 6m loggers like Ping Jockey or N0UK eme pages. ON4KST. I am hoping to have my 1100w 6m PA QRV by end of August to try eme. I will probably not have it ready for the Perseids Meteor Shower. 6m is heading into the doldrums until Nov/Dec Es season, so good time to try out ms on 6m. A small yagi and 100w will work ms. I am QRV with the K3/10+Mirage PA (125w) into 30-foot long 6-element yagi. 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-100w, 1296-60w, 3400-?

Re: [Elecraft] K3-KPA500 Pelican Case
...which Pelican case works well for toting the K3 and the KPA500... Depends on whether you intend to carry it on board, or give it to the airline baggage handlers to throw around. IMHO, if you carry a K3 on board, Rose's cases are the best. I have yet to do research on a shipping case for either. Let's hope the group has some practical experience.

Re: [Elecraft] [P3] P3 and K144XV
Thanks Alan, I will go back in and check the initial set up for the K144XV as well as the P3 and K3. Certainly some sort of widely different gain setting on 2m.

The reference level is per-band so you have to adjust it for each band you operate on.

Re: [Elecraft] Yet Another KPA500 Question
Yup, 270v times .707 = 191v to get max RMS RF properly blocked. Using E squared divided by R, gives you 728 watts blocked by 270 VDC on diodes for a well matched 50 ohm load. Various tricks increase this range, but that explains the order of magnitude. 73, Guy.

[Elecraft] P3: Span control logic
Hi all, especially the K3 Product Management folks: I now have some time behind the combination K3-P3, It is a wonderful combination. Like fishing with a fishfinder! Now my neighbor has definitive proof in writing (a screen snapshot) that he is indeed 6.5kHz wide when he cranks up that Macho Bass to impress his buddies on 14.250 :) The P3 is a wonderful addition to my station's capability, however, there is one ergonomic detail that drives me absolutely bonkers! I wonder if something can be done about it, as I may not be the only one with this issue. SPAN is equivalent to WIDTH to me. On K3, turning the WIDTH knob to the left (counter colockwise) makes the width of the bandpass NARROWER (smaller). Turning the knob to the right (clockwise) makes the bandpass WIDER. I have always loved how this works in this radio, it is logical and intuitive to me, from my background in video... Video Production Switchers (Vision Mixers for the Brits among us) Key Clip controls work this way, and my feeble mind is used to this convention after many years of mental conditioning. Equipment with similar controls (namely Yaesu rigs) are backwards to me. Having said that, on the P3, selecting SPAN and turning the knob to the left (counter clockwise) makes the span NARROWER, and turning it to the right (Clockwise) makes the span WIDER! Yes, I know... The VISUAL FEEDBACK from the K3 control matches the screen of the P3, which is good, but the INTENT of the action on the P3 SPAN control does not! The WIDTH of the marker WIDENS when you turn the knob counterclockwise, but the actual EFFECT of the action you are performing is BACKWARDS from the visual feedback, and also backwards from the K3 control that does the same thing! Its like on a sailboat... Deflecting the rudder tiller AWAY from you turns the nose of the boat in the OPPOSITE direction from the tiller deflection. The chosen behavior of these controls and how they interact with the action and visual feedback is just absolutely counter intuitive to me... Any hope that this can be made a user selectable behavior so we can all have our cake and eat it too?

Re: [Elecraft] P3: Span control logic
Lu, I am sorry, but you will have to divorce your concept of width with the SPAN of the P3. Instead of looking at the width of the signal, look at the range of the display - that is what SPAN has meant for many years to those familiar with spectrum analyzers - it is the difference between the frequency on the left of the screen and that on the right of the screen. Yes, the width of the signal being observed will shrink as the span is increased. The SPAN term has no relationship to the width of any particular signal, it is only the extent of the display frequencies on the screen. Alan, please do not change it - it makes sense to many (hopefully most) of us. Lu, you may want to think of SPAN as the opposite of WIDTH. I hope that helps.. 73, Don W3FPR On 8/7/2011 6:34 PM, Luis V.

Re: [Elecraft] P3: Span control logic
Don: Do you understand TV waveform monitors? When you look at a NTSC transmitter output waveform, the white level is on top and the sync tip is at the bottom. This is upside down, as the sync tip is peak transmitter modulation and white is low modulation. But the graphical representation was designed for a USER, who is tasked with adjusting levels on a camera, and not a transmitter, and it is easier, logically, to deal with the adjustments when white is at the TOP of the graphical representation instead of the bottom. I am quite familiar with spectrum analysers. And I can understand the issue you raise, because in spectrum analysers, yes, SPAN functionality as its illustrated on the P3 makes sense... within the context of a spectrum analyser! Yes, I understand what SPAN is; and if the unit was a actual stand alone spectrum analyser lab instrument, you would be completely accurate logically, because it wouldnt have the width control on the K3 to clash with. But its not a spectrum analyser lab instrument, it is a receiver accesory with a graphical display of the K3 signal reception conditions. We are showing the WIDTH of the filter in the picture representation of the K3 filter WIDTH. And it makes sense in the graphical representation of the action because as you turn the knob to widen the bandwdth, the picture icon widens. This behavior then clashes with the SPAN control, which shows a graphical representation of the WIDTH of the scan. Using the original logic as defined in the K3 WIDTH control, it is backwards from the established control logic of the K3 width control. It wont make me lose sleep, and I may ultimately adjust, but I am simply stating the clash of the control's behavior as applied to the usage of the instrument for its intended purpose. Since the logic of what we are doing here is to show the WIDTH of the spectrum we are displaying, the logic fails because when we turn to the left, it gets bigger and when we turn to the right it gets smaller, and, the following is important, it does this against the convention set by the K3 width control. However, if the width control worked like it works on Yaesu equipment, there would be no clash. I remember a similar discussion about the K3 Width control on the reflector a few years back and all the angst because it worked backwards. Simply stated; Product Management needs to choose a standard and stick with it across the product for the sake of the user! So, taking into account the K3 width control's logic, what's wrong with the option to make it either way, via a menu setting, other than time and resources?

I see no conflict for a *FILTER* knob if turned to the right (clockwise) towards the plus sign the filter widens (as indicated by the display on the radio) for the *SPAN* located on the P3 after the Span button is tapped the the P3's knob if turned to the right (clockwise) the span widens/increases the discrepancy is within your head and how *you* choose to interpret what the knob should be referencing to the entire display (frequency span) or the tiny little parts of the display that represent the filter widths within the entire display apples and oranges GB 73 K5OAI Sam Morgan On 8/7/2011 8:02 PM, Luis V.

[Elecraft] K2 Control Front Panel Resistence Checks...Do my numbers jive?
Evening Everyone, I am totally done with the control panel, and right at the resistance check part of the front panel on my K2. On some of my readings, I am not getting a reading at all. I have a Meterman multimeter. When the probes are crossed, 0.4 or 0.5 Ohms are considered zero or ground on my meter. I am getting some infinite readings on my meter, even on the 2000k Ohm setting. I just get a 1 at the beginning and nothing else...I am guessing that is infinite. I checked the board for unsoldered components, solder bridges, and the like, and found nothing. Here are the readings I am getting on both boards. Could someone verify that my numbers jive with what I should be getting? CONTROL P2-1==Infinite U5-5V==14.85k U4-8V==3.49k Q1 collector==Infinite Q2 collector==Infinite U3-8==1003k (would that be 1.003 M Ohms?)

Sorry, Lu ... I am quite familiar with spectrum analysers. And I can understand the issue you raise, because in spectrum analysers, yes, SPAN functionality as its illustrated on the P3 makes sense... within the context of a spectrum analyser! The P3 - or any panadapter - is precisely a spectrum analyzer. The span control has no relationship to the K3's width control (but I would have preferred the K3 Width control to have been labeled selectivity and worked backward G). So, taking into account the K3 width control's logic, what's wrong with the option to make it either way, via a menu setting, other than time and resources? Only if you're going to provide an option to reverse the sense of the Width control as well G. 73, ... Joe, W4TV On 8/7/2011 9:02 PM, Luis V.

Re: [Elecraft] K2 Control Front Panel Resistence Checks...Do my numbers jive?
David, Sorry to be crass, but if you do not understand (greater than) or a range of allowable resistances, I cannot be of much help. I examined the first 6 of your readings and found them to be within the values that are specified in the manual. I do not desire to go any further and check all your measurements. If you have readings that are out of the range listed in the manual, then I will certainly be responsive, but in those forst 6 readings, all seems to be OK. 73, Don W3FPR On 8/7/2011 9:34 PM, David Dietrich wrote: Evening Everyone, I am totally done with the control panel, and right at the resistance check part of the front panel on my K2.

[Elecraft] Elecraft CW Net Report for August 7th 8th, 2011
Good Evening, Two decent nets today. Twenty meters was fairly open and I could hear most folks really well. One guy from the Northwest Territories was booming in while only running 10 watts, VE8RT. Two were ESP but I dug them out: K0DTJ and WB3AAL. Ron was much worse than Brian but I got his call twice and a few other words. Other than that it was just a slight tone under the noise level. Forty meters was noisier than it normally is on 40 but I got N0TA in Colorado well enough to copy most of what he sent. That has not happened in quite a while. Lately 40 meters has been an Oregon California only band for me. Maybe as we slide to the late part of summer it will grow stronger. I have noticed lately the sun is rising later. I awaken in the grey of dawn instead of to the sun peaking over the mountain. It is also setting earlier. Weather has been monotonous lately. Pretty much the same high temperatures each day and the same lows at night. Not quite 70 and right around 50. For once I did not have the coldest daytime temperature. Brian came in with a 53 and foggy report. Even the folks in Canada have been warmer than it is here. On to the lists = On 14050 kHz at 2200z: W8OV - Dave - TX - K3 - 3139 N0TA - John - CO - K3 - 994 W0RSR - Mike - CO - K2 - 5767 K4JPN - Steve - GA - K2 - 1422 K1THP - Dave - CT - K3 - 686 K0DTJ - Brian - CA - K3 - 4113 AE6IC - Fred - CA - K3 - 2241 W0CZ - Ken - ND - K3 - 457 N0AR - Scott - MN - K2 - 4866 N5URL - Bob - OK WB3AAL - Ron - PA - K2 - 1392 N7KRT - Jeff - TX - K2 - 5471 AB9V - Mike - IN - K3 - 398 VE8RT - Ron - NT - K2 - 7176 On 7045 kHz at z: AE6IC - Fred - CA - K3 - 2241 K0DTJ - Brian - CA - K3 - 4113 K6PJV - Dale - CA - K3 - 1183 N0TA - John - CO - K3 - 994 A couple friends of mine stopped by this morning and commented on my wood pile. So I took them for a walk. I showed them the wind damage and all the trees yet to be cut. We ate a lot of berries along the way and kicked up a couple of deer. The deer only flushed a little way because it was around noon. They wanted to sleep so as we walked along we kicked them up again. I think they may be a little grumpy at me for awakening them :) It was a nice hike on a mild day. Then they left to scout a few other places on the mountain. They mentioned an elk wallow they had found last year and wanted to see if it was still in use. I guess elk roll in the mud to cut down on fly bites. Until next week stay well, 73, Kevin.

Re: [Elecraft] P3: Span control logic
Kenwood? On the TS-930 clockwise is widest in CW, counter clockwise narrows. In this case I think it is just as logical to state that, just as I reduce the volume by going counterclockwise I also reduce the bandwidth by going counterclockwise. Neither way is right or wrong it is just a learned preference. I open my own jars and my first radios only had barn door wide for bandwidth. 73, Bob K2TK ex KN2TKR (1956) K2TKR No, no, no...every filter control I've ever used (until the K3) narrowed the filter bandwidth as the knob was rotated clockwise.
