[Elecraft] K2 10m sensitivity
I have just received a new old K2 here. It has most of the important mods, AtoB upgrade, and is working as well as it can, as best I am able to determine. The alignment is fine, and it puts out OK on all bands. I have not been able to find any posts about the sensitivity on 15m-12m-10m being not so great. On 40m-80m-160m it is what I would expect. 20m it's just OK with wider filters, but there is plenty of internal noise with the narrower filters. I don't have a microvolt source to get a precise reading. But with a 5 el yagi on 10m, band noise completely covers internal noise on my Yaesu. On the K2, I can hear the band noise, but the internal noise is rather more than I like. Even strong signals don't move the S meter much, and that is after I have tweaked the settings, and adjusted the AGC threshold. I know audio filtering will help with this. I also did the mod to increase the gain of the RF preamp. I wonder if anyone else sees the 10m sensitivity as a problem? Is there perhaps a wider bandwidth transistor to use in place of the 2n5109?

[Elecraft] K3 general coverage RX with KBPF3
how is the sensivity with KBPF3 for RX outside of HAM bands? Is KBPF3 (and KFL3A-6K) a good invest or is a better way to buy a special radio for BCR RX (eg. like Perseus or PMSDR)? __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] K3 Board Re-seating Guidelines
I'm having a couple of interrmittent K3 problems, both of which have lead to suggestions of reseating the boards. The oldest problem is the VFO A lockup that an early warranty trip back to Elecraft came back with problem not found, probably cured by FedEx jostling on the way. That has occasionally re-appeared, but a new problem (intermittent hum related to mic/headphone connection to MK2R+ interface) has started up. Is there a document or any instructions on disassembly/board reseating? I didn't build the K3, I've Googled and search Elecraft.com. The K3 Assembly Manual doesn't seem to cover it, I've found guides for installing the DSP board and some AF stage upgrade guides that have disassembly instructions for those particular actions but wondering if there is a reseating guide floating around out there somewhere.

More to the point, and maybe I'm missing something very obvious, wouldn't having as good a receiver as possible be nothing but good for portable, compromise antenna operation?

[Elecraft] Re K2 10m sensitivity
My K2 has 0.1uV sensitivity for 10 dB signal to noise on 10m with pre-amp on, or 0.16uV with pre-amp off. The K2 has quite low gain compared to many radios and often needs the pre-amp switched in for the higher bands, also have you checked the alignment? There are various tables of measurements on my web site at: http://www.astromag.co.uk/k2/ 73 Dave, G4AON K2 #1892, K3 #80 I have not been able to find any posts about the sensitivity on 15m-12m-10m being not so great.

Re: [Elecraft] KX3 vs. K3 and other rigs?
I think part of the problem when discussing 'good receiver performance' is in the definition. In a trail friendly radio I expect a receiver that is able create a readable signal with a very inefficient antenna. To me a TFR doesn't have to worry so much about blocking locally produced strong signals. I wouldn't expect a TFR to do well as well as a K3 at a multi-transmitter contest site such as Field Day.

Re: [Elecraft] K3 general coverage RX with KBPF3
My K3 has around 10 dB worse image rejection when operating outside the ham bands with a KBPF3. Sensitivity is mostly OK except when using the main (TX) antenna socket were the sensitivity drops off below 1 MHz and is about 20 dB less sensitive on 500 KHz. If you use the KXV3 transverter interface the sensitivity isn't reduced. I also have a Perseus, which is really good but of course requires a computer. If you are seriously into broadcast band listening the Perseus offers the neat trick of allowing you to record 1600 KHz chunks of frequency to replay later, which means you can record the whole of long and medium wave overnight and listen the following day. 73 Dave, G4AON -- how is the sensivity with KBPF3 for RX outside of HAM bands?

Re: [Elecraft] K2 10m sensitivity
The 10 meter sensitivity of the K2 is normally quite good. I would suggest checking the tuning of the bandpass filters. When tuning the bandpass filters, remember that they are shared by 2 bands, and you must tune the inductors first, and after that, tune the capacitors. Do 10 meters first, then 12 meters -- do 15 meters first and after than do 17 meters. Set the K2 power to 2 watts, connect a dummy load and adjust the proper bandpass filter element for a peak in the power output. If the power increases dramatically, exit tune and then re-enter to drop the starting power back down to the 2 watt level. After adjusting the bandpass filters to a peak during a transmit (or tune), they are properly tuned for receive too. You will need to buy or borrow a calibrated signal generator to make any definitive measurements of the sensitivity. It is difficult to make a judgement based on antenna noise alone without some instrumentation. The Elecraft XG3 is a great tool to do exactly that - it has controlled output levels and can be used to make MDS measurements, and you can use it to properly set your S-meter. 73, Don W3FPR On 6/6/2011 3:36 AM, Alastair Couper wrote: I have just received a new old K2 here.

Re: [Elecraft] K3 Board Re-seating Guidelines
John, There is nothing specific to re-seating. If you use the existing board assembly steps in reverse, then put it back together again, you will have accomplished the re-seating. Normally, you do not have to re-seat all the connectors - just the ones involved in the problem, and it normally involves the DSP and Front Panel boards. The replacement steps for the upgraded DSP board should have all the information needed to do that task. 73, Don W3FPR On 6/6/2011 6:46 AM, John K3TN wrote: I'm having a couple of interrmittent K3 problems, both of which have lead to suggestions of reseating the boards.

Re: [Elecraft] KX3 vs. K3 and other rigs?
Here are a couple of additional factors to consider. 1. Increasing the output power to 20 or 30 watts would have an impact on either the weight of the KX3 (more batteries needed to maintain a desired battery life) or the battery life (the existing batteries would not last as long at the higher power level). 2. It is much easier to add an external power amplifier, if desired, than to significantly improve receiver performance at a later date. 73, Dave, KQ3T On 6/6/2011 12:25 AM, juergen wrote: Hi Kristinn What i dont get is why people expect so much performance from a so called portable rig.

[Elecraft] P3 Fixed Tune Mode
I think this is a very good idea. My preference of course would be if the window on the P3 would track/scroll as you move the VFO, keeping the VFO frequency centered, a la Icom. I realize that this would mess up the waterfall... So dont allow it when using the waterfall or a split spectrum/waterfall display! Just allow it when the unit displays only the spectrum display. The difficult thing would be to manage the fonts and the graticule... I dont know if there is enough processing power in the P3 MCU to deal with this. I would also like to add my vote for the ability to monitor my transmitted signal (without having to unplug the serial port) on the P3 display. But most of all, I would like to see a factory approved modification that would allow me to place the P3 on the IF output of my KRX3 so that I could monitor another band, say 10 meters, for signals while working a run on, for example, 20 meters. This output could be switchable from the K3 panel (Main RX/Sub RX). An even NEATER trick would be to split the screen to two displays, one the spectrum of the main, the other the spectrum of the sub. I would even accept a 50% screen refresh penalty for this feature, sort of like the spectrum display works on Orion. Knowing when the second band has signals on it without the cluster... *THAT* would really be a terrific thing to me!

Re: [Elecraft] And/Or Options
Wayne, If a VHF option is possible, but would require some substitution, is it possible to have it be an alternative to the internal battery option instead of the ATU? Maybe I'm in the minority, but to me, the internal ATU is much more valuable than the battery option. External power is much less problematic than a good ATU. I'm pretty sure that, if I had to pick between the ATU and a VHF option, I'd drop the VHF idea. I suppose, though, the ATU wouldn't be operational on VHF anyway, so perhaps that is why you suggest it as the alternative option?

Re: [Elecraft] P3 Fixed Tune Mode
Lu, Isn't tracking the VFO the way the P3 works when in Tracking mode ? Am I misunderstanding you? BTW, the split screen with inputs from both receivers is a great idea!

Re: [Elecraft] KX3 vs. K3 and other rigs?
I will start by stating that the Texas DX Society has found the Kenwood TS-480 to have a receiver that is adequate for DXpedition and Field Day work. As contest director of TDXS I am in complete agreement with this finding. I know only what has been published on this forum about the KX3 which leads me to believe that the KX3 will probably have a better receiver than the TS-480 and approach that of the K3. The architecture of the KX3 promises to be a good deal more flexible that the TS-480 with a control head and remote transceiver. The TS-480 is not in the picture for a back pack operation. My opinion is that the KX3 will be a great winner if it equals the TS-480 because it is more flexible. If it is as good as the K3, that is even better. If any design team is capable of K3 performance in a flexible package, it is Wayne, Eric, et. al. and I am eager to see how they come out. They are very brave to give us the preliminary peek we now have and I am eager to see the final product, but not so eager that I want them to release it before they are ready.

Re: [Elecraft] KX3 vs. K3 and other rigs?
Hi Dave The point you make about the added complexity is valid. However from a communications effectiveness point of 20 watts is a much more realistic power level, especially for SSB QSO's. Most of the Mil Manpacks use this output power level. I operate portable using mil HF manpacks with the power varying between 20 and 30 watts. I also have a SGC2020. 95% of the time on the first call I can get through and have the standard cookie cutter qso's and move on. If you try and do the same with 10 watts its very frustrating and much more of a struggle. These are NA Q's not local stuff. 5 to 10 watts is good power level for CW. For SSB 20 watts is far more effective, even with simple whips. Everyone will say its only 3db, however that 3db makes a huge difference when using simple antennas especially on SSB. While the AMP might be the answer, looking at the projected images and size, it will be a huge hassle carrying another box around. If you consider the size of Yaesu FT857, which runs a full 100 watts of output and its design is very neatly integrated into a tiny package, the KX3 with an external amplifier will be awkward by comparison. A FT857 with some AA batteries was carried to the top of Mount Kilimanjaro by HB9BXE. The operator successfully had many qso at 20 watts of output. He probably would not have packed a KX3 and amplifier if it was available then. I dont see why a duplicate of the KX3's PA could mot be offered as a piggy back box with another set of 8 batteries. I would rather follow that option than the 100 watt linear option. It certainly would be a lot smaller and portable than the 100 watt PA. I am sure many homebrewers will explore this option. Anyway time will tell. There is always the hombrew/modification option.

Re: [Elecraft] KX3 vs. K3 and other rigs?
Back in the late '60's I helped develope and test the first RACAL military SSB Manpack (basically 3-8 Mhz). It used an flexible tape whip approcimately 10ft long. This was end loaded using a permeability tuned circuit internal to the rig. Although it worked well, I don't believe there is enough room in the KX3 for such a circuit. Also, the antenna was mounted directly on the face-plate to minimize losses (Hah!) I'm pretty sure the PCB mounted antenna socket on the KX3 (a guess!) would not be able to take the stress. As for if your can't hear them... etc., my K2 could hear the rare DX but, with my low backyard dipole, most of the time I couldn't work them... but it was still a thrill to be able to hear them. My best qrp SSB dx (to date) with 5W + dipole is Beijing on 20M.

Re: [Elecraft] And/Or Options
The KXAT3 will have the same matching range as the KAT3. The only difference is the power-handling capability, and the use of latching relays so RX-mode current drain is zero when not actually tuning the L- network. 73, Wayne N6KR On Jun 6, 2011, at 7:57 AM, John Ragle wrote: This is exactly correct!

Re: [Elecraft] Elecraft Digest, Vol 86, Issue 14
Yay! Make it bolt to the underside of the KX3 with a cavity for a skookum battery of our choice and you've got an instant winner for tactical SSB. An effective ATU would need to be part of the design; something that would tune a modest-size whip. I still maintain that 10W - even with speech compression - is not enough for SSB. Part of the problem is that many 'home base' stations suffer from high manmade noise levels. Operating portable in the bush with a hot receiver it may seem like they should be able to copy us because their 100W signal is S9, but if their noise is S8 and the bush radio is only 10W ... Practical tests communicating between bush camp and home consistently proved that 10W CW was clear copy every night, but SSB was hit and miss. 25 watts would have made all the difference. I would have been totally happy with cw, except the other hams in my family are morse-challenged.

Re: [Elecraft] KX3 vs. K3 and other rigs?
World-class contest stations are a different animal. If the extra 3 dB adds an extra 0.1% to the contact total, that could easily be the difference between winning and coming in number 2. But for the average ham a 0.1% increase in your total contacts is such a small difference that you would never even notice it.

Agreed. And at that level of competition, operator skill makes a much bigger difference in score than 3 dB of power. Sadly, many who try to compete at that level just don't seem to understand this.

Re: [Elecraft] KX3 vs. K3 and other rigs?
The KX3 (K3 Extremely Portable is how I think of it) does have 3db of additional power compared to the intended market: 5w QRP portable. The portable QRP market is where Elecrafts' roots lie, after all, so it should be no surprise that the KX3 is aimed at that target. Having an optional external 100w amplifier makes it practical for field day and other mobile operations, too, and perhaps some really constrained home stations where even a small K3 will not fit.

Re: [Elecraft] (no subject)
Another (possibly cheaper) mathematical computation system for doing signal processing is Mathematica by Wolfram. Mathematica is used quite a bit in the academic world for a very wide variety of computational problems. With regarding to signal processing there is support for various types of DSP implementations supporting image processing, sound processing, and RF signal processing. But, a professional version of Mathematica is about $2500 these days. At least, that is what we pay for it at work. I do have my own copy at home, actually two copies, for the At Home edition which costs only $295. Everything I can do on the professional version at work I can do with the At Home edition. There are only a few limitations of the Home Edition of Mathematica and so far I have not run into any of them. The license limits you to one Home edition per computer so I have purchased one copy for my Apple Mac laptop and one copy for my desktop iMac-24. Yes, I use both systems even to do Mathematica stuff. By the way, I also have the professional (or, commercial) license to Matlab which I have used for some contract work a few years ago. I still play around with it from time to time but my first love is Mathematica. I have also played around with Mathcad which although is nice and has some cute features for documentation, it is not anywhere close to the capability of Mathematica. So, at $295, the Mathematica Home Edition is quite a good buy. So, if you want to experiment with Mathematica you might consider the Wolfram Alpha web site at http://www.wolframalpha.com. The command entry window on Alpha will accept most (if not all) Mathematica commands that you can type in. For example, to integrate the six(x) function, just go to Wolfram Alpha and type in: Integrate[Sin[x],x] In the command above, capital letters are important and the use of square brackets [] is important. If you want to play around with some of Wolfram Alpha features, start by typing in your name, just your first name like Phil, Roger, Dick or whatever. 73, phil, K7PEH On Jun 6, 2011, at 3:36 PM, John Ragle wrote: For a while, I have been trying to add to my library a book on DSP that was mid-way between cookbook and pure theory.

[Elecraft] Elecraft [K3] Macro Mess
I've read the K3 Programmer's Reference and the K3 Utility (V1.4.4.25) Help. Perhaps a programmer can understand it, but it offers me no step-by-step guide as to how to construct a Macro. So I suppose I'll limit myself to Macros others have written - but I based on the following experience, I have no confidence that I can assign them to a M-Key. I tried to implement a simple Audio Mixer Command, !bed3, that was listed in an October 2009 posting. I edited Macro 1, gave it a name, and wrote it to the K3. I entered the CONFIG Menu and selected Macro. I pressed 1, and the then the M3 key to assign it to the M3 Key. When I pressed the M3 Key, the name I'd assigned to the Macro was displayed, but the Macro did not execute. I could execute it from the K3 Utility, but not from the M3 Key. A subsequent READ MACROS FROM K3 showed that !bed3 was assigned to the Name I'd used for MACRO 1 I know the Audio Mixer functionality is now on the CONFIG Menu and this exercise was unnecessary, but I wanted to try something that was simple. I'd sure like to know what I did wrong? I doubt my ability to assign ANY Macro to an M-Key. Further, I have no DVR and tapping any of the M1-4 buttons returns NO DVR. The K3 Utility Help says to restore standard memory recording functions to tap the REC Key followed by the M-Key to be restored. The only way I could restore my M3 Key to returning a NO DVR Message was to send Blank Macro named NO DVR and then assigning that to the M3 Key. I would expect the restoration procedure to have done this. I have little confidence that getting the message to coincide with the other M-Keys makes that Key behave as the others. Also, several times after I'd written the Macro to the K3, the K3 MAIN Audio was muted. The S-Meter read full scale, and there was no audio. Cycling power restored operation but it was an unpleasant occurrence. 73 * Dave, W9ZRX __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
