But it would be nice to be able to compare and see how the enhanced mic audio and what not are done as the series 1uF caps from W9AC are still in place... Brett, On Rev. D of the Main DSP Board, mic coupling cap C28 was increased from 0.1 uF to 1 uF. On the alternate mic path, R24 and R26 were scaled from 1K to 10K while keeping C36/C37 at 1 uF. A 10x scaling increase in series resistance has the same net effect on the low-frequency turnover point as does a 10x increase in series capacitance. Line In was affected the same way with an increase at R18/R20 from 1K to 10K while keeping 1uF of series capacitance. The 10K + 1uF combination is good for keeping circuit Z and low-end audio response reasonable while minimizing SMT parts size and cost.

Re: [Elecraft] K3 needs survey -- firmware and application software
If it's not too late I would like to add another couple of requests. 1) Add Accukey emulation so I can send CW with the K3. 2) Since the new DSP mods extends the bandwidth down to minus DC, implement phasing detection to improve the opposite sideband rejection. Even without the bandwidth extension, the SSB opposite sideband rejection is not the greatest.

Many of the most-requested changes were made over the past several months, keeping pace with the demands of the fall/winter contest season. (A few that come to mind: switch sequence automation via macros, improved DVR interaction with PTT, main/sub audio mixing, improved NR, lockable transmit controls, and many enhanced remote-control commands.) As we head into 2010, we'd like to refresh the master firmware list based on your input. Items already on the list have priority, of course, but this is a great opportunity to let us know what else is missing or could be improved. Our goal is to make the K3 as easy to use as possible, while providing the advanced features you need for specific operating situations. We're also planning a renewed effort to assist application software developers. If your ideas for improvements involve changes to both K3 firmware and a favorite application, we'll pass it along to the developers and work with them closely.

[Elecraft] [OT] High SWR on 20 and 40
Hello, I have been trying to troubleshoot my antenna system, and have been trying to avoid the dreaded high swr post, but I've run out of ideas, so I'm turning here. First let me explain my system. 67' dipole fed by 16' of window line. That's connected to an Elecraft balun. From the balun, there's a short piece of coax going to a barrel and into the basement (through a piece of cement backerboard. From inside the basement, there is another piece of coax, about 12', connected to the barrel, and going up into the bedroom directly to a K2 with an autotuner. Before the K2, I was using a Yaesu FT840 with an MFJ tuner. After tweaking the window line length and the actual length of the dipole, I never really had a problem with SWR (well, according to what the MFJ was saying, which may or may not be totally accurate.) Usually 1.5:1 or under on all bands. With the K2/KAT2 in place, the SWR reported by the tuner is all over the place. The only one that gets less than 1.5:1 is 30m. Most bands are pretty random, anywhere from 3:1 to 7:1. However, on 20 and 40, it generally does not get below 9.9:1. I've tried 4 different lengths of coax between the barrel (inside) and the rig... 3', 6', 12' 20'. I've tried a couple different lengths between the balun and the barrel on the outside. When I attach the balun directly to the K2 I get 1.3:1 on all bands (most are 1:1.) With a short piece of coax between the rig and the balun, I get the same results. I've also attached my dummy load to the barrel on the outside of the house, and tested it from the shack, and I saw 1:1 no problem. I totally understand the concept that if A works and B works, A+B doesn't necessarily work. I understand it's a whole system. But I've tried so many different combinations of coax on each side, and don't understand why my SWR is basically infinity:1 on 20 and 40, when they seemed to match reasonably with the old system. I have not tried different lengths of window line between the dipole due to the fact that I had it perfectly trimmed for my old system. But I have plenty of it and would be open to trying anything. Just trying to get the most I can out of my modest 10W. :) Any suggestions would be appreciated! 73, Dave K8DJW -- View this message in context: http://n2.nabble.com/High-SWR-on-20-and-40-tp4401077p4401077.html Sent from the [OT] mailing list archive at Nabble.com. __ 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
Re: [Elecraft] [OT] High SWR on 20 and 40
Dave, Is that a 1:1 balun or a 4:1 balun. Usually a 1:1 works better, but whichever balun you are using, try the other one and see what happens. Do you have an antenna analyzer? or can you borrow one? If so, what is the impedance at the end of the coax? Both the resistive and reactive components please - just the SWR does not provide much information on how to advise you to proceed. You may be better off eliminating the coax entirely and running the window line all the way into the shack. 73, Don W3FPR djmd wrote: Hello, I have been trying to troubleshoot my antenna system, and have been trying to avoid the dreaded high swr post, but I've run out of ideas, so I'm turning here.

Re: [Elecraft] [OT] High SWR on 20 and 40
I think he would be better off throwing away the window line and eliminating the tuner. Cut the length of the dipole for resonance on 40M and then add a 20M dipole in parallel at the feed point. There will be some interaction, which can be lessened by orienting the dipoles at right angles to each other or at least getting some angular separation. Conventional wisdom (not always correct) says to use a 1:1 current balun at the antenna. With only 10W you don't want to be throwing it away in lossy tuners and mismatched transmission lines. Wes N7WS ps. The only tuner I use in my shack is the pi-net in my L4-B. --- On Fri, 1/15/10, Don Wilhelm w3...@embarqmail.com wrote: From: Don Wilhelm w3...@embarqmail.com Subject: Re: [Elecraft] [OT] High SWR on 20 and 40 To: djmd d...@fuse.net Cc: elecraft@mailman.qth.net Date: Friday, January 15, 2010, 1:45 PM Dave, Is that a 1:1 balun or a 4:1 balun. Usually a 1:1 works better, but whichever balun you are using, try the other one and see what happens. Do you have an antenna analyzer? or can you borrow one? If so, what is the impedance at the end of the coax? Both the resistive and reactive components please - just the SWR does not provide much information on how to advise you to proceed. You may be better off eliminating the coax entirely and running the window line all the way into the shack. 73, Don W3FPR djmd wrote: Hello, I have been trying to troubleshoot my antenna system, and have been trying to avoid the dreaded high swr post, but I've run out of ideas, so I'm turning here. First let me explain my system. 67' dipole fed by 16' of window line. That's connected to an Elecraft balun. From the balun, there's a short piece of coax going to a barrel and into the basement (through a piece of cement backerboard. From inside the basement, there is another piece of coax, about 12', connected to the barrel, and going up into the bedroom directly to a K2 with an autotuner. Before the K2, I was using a Yaesu FT840 with an MFJ tuner. After tweaking the window line length and the actual length of the dipole, I never really had a problem with SWR (well, according to what the MFJ was saying, which may or may not be totally accurate.) Usually 1.5:1 or under on all bands. With the K2/KAT2 in place, the SWR reported by the tuner is all over the place. The only one that gets less than 1.5:1 is 30m. Most bands are pretty random, anywhere from 3:1 to 7:1. However, on 20 and 40, it generally does not get below 9.9:1. I've tried 4 different lengths of coax between the barrel (inside) and the rig... 3', 6', 12' 20'. I've tried a couple different lengths between the balun and the barrel on the outside. When I attach the balun directly to the K2 I get 1.3:1 on all bands (most are 1:1.) With a short piece of coax between the rig and the balun, I get the same results. I've also attached my dummy load to the barrel on the outside of the house, and tested it from the shack, and I saw 1:1 no problem. I totally understand the concept that if A works and B works, A+B doesn't necessarily work. I understand it's a whole system. But I've tried so many different combinations of coax on each side, and don't understand why my SWR is basically infinity:1 on 20 and 40, when they seemed to match reasonably with the old system. I have not tried different lengths of window line between the dipole due to the fact that I had it perfectly trimmed for my old system. But I have plenty of it and would be open to trying anything. Just trying to get the most I can out of my modest 10W. :) Any suggestions would be appreciated! 73, Dave K8DJW __ 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
Re: [Elecraft] K3 Audio monitor delay
I've not noticed any significant delay in the TX monitor, and I know I would find it disconcerting if it was there. Not sure if TX EQ, or some other option, might introduce such a delay. The delay is due to: audio input anti-aliasing filter in the A to D, TX AF filtering, phase shift network, interpolation filter (conversion from 12 kHz sampling rate to 48 kHz sampling rate) , post-IF clipper filter, decimation filter (conversion from 48 kHz sampling rate to 12 kHz sampling rate), reconstruction filter (part of the D to A). We thought it best to allow you to hear the effects of the IF signal processing, so delays are unavoidable. Most people do not notice as the K3 uses filters optimized to minimize delays. Note that Tx EQ adds zero additional delay. Like the Rx EQ, the Tx EQ just adds more constraints to the AF FIR filter generator. There may be opportunity to further redice delays by combining some filter functions. One of the items on my list of background tasks :-) 73, Lyle KK7P __ 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

Re: [Elecraft] K3 needs survey -- firmware and application software
2) Since the new DSP mods extends the bandwidth down to minus DC, implement phasing detection to improve the opposite sideband rejection. Even without the bandwidth extension, the SSB opposite sideband rejection is not the greatest.

Re: [Elecraft] Advantages of Factory Assembed Tested K-3 vs. a Kit?
I think the K3 goes together much better then a PC. I built my K3 a week ago and I am still in awe of the precision of engineering that went into that K3 kit. Parts went together smoothly just as if they were designed to do that -- of course, which they are but the fit was perfect. There is only one little wish and that is I wish for slightly smaller fingers for just one or two steps in the K3 kit building process. Now, this was really not a problem but it was a bit tight but still what I would call easy. I mean, no sweat on my brow for this job at all. Alignment? What alignment? I used the K3 Utility program -- your alignment steps consist of hitting a few buttons on the K3 Utility screen! Simple as 3.14159+. And, it is probably just as simple to do it from the screen but a little more time consuming. 73, phil, K7PEH On Jan 15, 2010, at 2:23 PM, James Sarte wrote: Hi Dick, Alignment of the K3 is performed either by using a computer utility or via the front panel.

Hi Dick, Alignment of the K3 is performed either by using a computer utility or via the front panel. You don't have to adjust anything. Also, assembly of the K3 is like putting a PC together.

Re: [Elecraft] Advantages of Factory Assembled Tested K-3 vs. aKit?
I would imagine, judging from the ads, that a factory built K3 may have a slightly higher resale value but that doesn't matter to me since I doubt I'll ever sell mine! Also, since I saved nearly $400 building it that's probably a wash anyway. I sure enjoyed assembling the radio and it definitely gives me a sense of pride and even attachment to my K3.

Re: [Elecraft] K3 needs survey -- firmware and application software
If I use my XG2 as a source into the K3 and set the SSB BW to the default settings for my 2.8KHz 8-pole filter (100Hz to 2.9KHz) the signal which is S9 at its peak is still S7 at zero beat. A 100 Hz beat note on the wrong sideband is still S3 and a 200 Hz beat is S1. The equalizer has no effect of the s-meter. If I run this same test on my TS-870, even with the lower pass band set to zero, there is no opposite sideband, nada, zip. That's because the '870 uses the phasing method of detection in addition to crystal and DSP filtering. I am no DSP expert but I have been told that this would be pretty easy implement in DSP. So why not do it?

[Elecraft] Hats
I don't think I would want just a K3 hat. I would really like an Elecraft hat. I have a number of their shirts and wear them at Field Day and to the ARES meetings. The problem with having a K3 hat is the folks at Elecraft would also need to order K1 hats, K2 hats, KX1 hats, plus hats for each of the accessory kits. An Elecraft hat would make much better financial sense for them to order and give to their cadre. Remember: Elecraft makes many more rigs and kits than just the K3.

I don't see how the detection method would affect it. I just ran the same test. With my 2.7KHz filter I got S6 at zero beat, otherwise the results were much the same as yours. I admit it doesn't look too impressive, but I don't have anything else to compare it with. The S meters on other radios tend to be a lot more sensitive over the range up to S9 (i.e. fewer dB per S-point) which would make the opposite sideband rejection *look* better.

[Elecraft] First report about my new Yamaha CM-500
Well folks,finally after 2 months wait my boomset from Yamaha,arrived this afternoon. It look and feel very professional,the headset is big enough to cover my ears completeley,it isolate me from the outside world,they feel confortable. When I plug it into my K3 front panel phones jack,my first impression was WOW!! this sound great,for years I was using the Sony MDR-V150 that are sold in local audio stores for $20 and I thougt they were the best in the market,they really sound wonderful with any radio but these Yamaha leaves in the dust my old Sony,the audio quality is awsome,if you hear AM broadcast stations the lows are deep solid without any distorsion,even on ESSB If you find some one transmitting that wide,you enjoy that sweet sound. Now comes the mic,it needs 3V DC power,it comes with a little plastic case where you insert a couple of AAA batteries to feed the mic,then I connected it to the rear mic input and trough the quick config menu set it to rPH and bingo,nice TX audio,the gain is much higher than any of all the mics I have been using with my K3,so I had to lower the mic gain to just 10 and comp to same level,VOX works very easy with this mic,I set lastly the mic EQ and my audio goes very well balanced from 100 to 3000 hz. Its 00:30 UTC in SE FL now,I am on 40M if anyone will like to hear me on the air with it I will be available all night,just send me a direct email. I can tell that for just $38 this is a great investment that will put Heil to think about how to improve their mics or at least make them more afordable. If you have not order one of these,don't hesitate,do it.

Re: [Elecraft] [OT] High SWR on 20 and 40
It's the BL-2 switched balun that I have been using, and have tried both modes. Forgot that detail. I have also tried one of those baluns built from PVC - can't remember the manufacturer. It's a 1:1 as well. Same results. No analyzer yet, but I really should think about getting one. Planning on a lot of antenna experimentation this year. I have actually thought of eliminating the coax. I'm not sure if I can use the same route as the coax, with the metal window frames, gas pipe, water pipes, all nearby in the basement. But what about going right through the brick? I would not be opposed to doing something like this. And re: your follow up - all the testing was done with the KAT2. I have never disconnected it. I also should have mentioned that I do plan on using this antenna system with my old radio as well. Only 10w on the K2, but 50 or so with the Yaesu as well. (mostly digital and CW.) Don Wilhelm-4 wrote: Dave, Is that a 1:1 balun or a 4:1 balun. Usually a 1:1 works better, but whichever balun you are using, try the other one and see what happens.

Usually 1.5:1 or under on all bands. With the K2/KAT2 in place, the SWR reported by the tuner is all over the place. The only one that gets less than 1.5:1 is 30m.

Hector, Glad you like it. I have been using mine for months. But with the K3 rear input, you do not need the battery bias box. The K3 will supply the bias you need.

Re: [Elecraft] First report about my new Yamaha CM-500
I just received my CM-500s and am using the rear mic jack. Works fine that way with lo gain, bias on. As Jim reported, the mic has a lot of gain. It's quite bassy compared to the Heil but the EQ takes care of that. I opened the package and 10 minutes later I'm all set. The ear pieces are nice and large. Comfy so far.

Re: [Elecraft] monitor delay
I just consulted with my wife about this. She is a speeth pathologist and audiologist. There is actually a slight benefit to be gained by delaying the monitor signal ever so slightly. The benefit is you hear yourself a bit more accurately than if there were no delay whatsoever. The reason is called bone conduction. Plug both of your ears securely with your fingers and talk. You can still hear yourself, and this is due to the bone mass between your mouth and your inner ear conducting sound. When you're adjusting your transmit audio you don't want bone conduction interfering with how you really sound. Although the best method remains having someone else listen to your transmit audio while you speak, you can help your brain tune out the bone-conducted sound to a degree if the sound reaching your ears is delayed a little bit. This is a happy side effect of the delay in the monitor.

On Fri, 15 Jan 2010 19:29:33 -0500, DOUGLAS ZWIEBEL wrote: Maybe most people simply don't complain? ALL digital systems have some delay (known as latency) for two reasons. First, there must be A/D and D/A conversion. Second, any DSP system requires some processing cycles to do what it does. The amount of latency (in msec) depends on the sampling rate, the bandwidth, the number of bits, the speed of the processors, how much processing is going on, and to some extent, the skill of the programmer. If both radios use DSP, their latencies are additive. We humans don't notice the delay unless we have something to compare it to. That can be the live sound of our own voice, or the audio from your transmitter monitored in another receiver. And we're sort of used to delay -- it takes time for sound to travel through the air, roughly 0.8msec per foot (varies a bit with temperature). The internet has a lot of latency -- 50-100msec is typical. This is one of the key issues with a remote station, and it makes contesting from a remote station a real challenge. Internet latencies are additive to the velocity of propagation, and are due to the TCP/IP protocols used to route data packets and the communications between equipment that routes those data packets. 73, Jim Brown K9YC __ 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

Re: [Elecraft] Hats
Who pays for hats that are given away? In the end, the customers do, of course. Elecraft has small, informative, cost effective magazine ads that maximize the return on their advertising budget by targeting their niche market. They don't have broad product lines as the Japanese companies do, so they don't have to appeal to such a broad spectrum of customers. I'd prefer they focus on making the radios that meet our needs and continue to deliver outstanding support than spend money on hats. All of my Yaesu hats sit on a shelf in the closet. Now if they want to have caps made and sell them as Ten-Tec does, that's fine. Jim N7US -Original Message- I don't think I would want just a K3 hat. I would really like an Elecraft hat. I have a number of their shirts and wear them at Field Day and to the ARES meetings. The problem with having a K3 hat is the folks at Elecraft would also need to order K1 hats, K2 hats, KX1 hats, plus hats for each of the accessory kits. An Elecraft hat would make much better financial sense for them to order and give to their cadre. Remember: Elecraft makes many more rigs and kits than just the K3.

Re: [Elecraft] K3 needs survey -- firmware and application software
I was going to say, all of that being complained about, can be set any way you want. Try the SHIFT control on the front panel. Set the crossover *anywhere you want it*. The SHIFT setting is remembered by mode. Being able to hear down there was specifically requested by some who do not share your tastes. In the past the firmware would NOT ALLOW that degree of downward shift. Now both of you can now set it like you want it. 73, Guy.

A 100 Hz beat note on the wrong sideband is still S3 and a 200 Hz beat is S1. The equalizer has no effect of the s-meter. If I run this same test on my TS-870, even with the lower pass band set to zero, there is no opposite sideband, nada, zip. That's because the '870 uses the phasing method of detection in addition to crystal and DSP filtering. The S meter measures the amount of signal that gets through the filters. I don't see how the detection method would affect it. I just ran the same test. With my 2.7KHz filter I got S6 at zero beat, otherwise the results were much the same as yours. I admit it doesn't look too impressive, but I don't have anything else to compare it with. The S meters on other radios tend to be a lot more sensitive over the range up to S9 (i.e. fewer dB per S-point) which would make the opposite sideband rejection *look* better. I think you can move the filter further away from the carrier by playing with the offset values in the filter setup. - Julian, G4ILO.

[Elecraft] Kit or not to kit
Puting the K3 together is the only way to go. As stated in previous emails, when a mod comes up, you already have a good idea on how to do it. For example I put in the new DSP board. I did have the assembly book infront of me. Short of losing a few parts and cracking a knob. It was long, but simlpe. I am 59 years old, making kits takes me back.

Re: [Elecraft] [OT] High SWR on 20 and 40
The 16 feet of window line makes me wonder if you're not trying to do a half-size G5RV, but got the top dimensions wrong. It would be 51' (instead of 67 which is REALLY bad on 20 meters), or a little longer, say 54' if you wanted to load on 17m and 12m. My K2/10 and the auto tuner will match most anything, but your lengths are not anything I would do on purpose for multiband : ) On Fri, Jan 15, 2010 at 7:49 PM, Don Wilhelm w3...@embarqmail.com wrote: Dave, If you did not disconnect the KAT2, then please tell us the setup (all the connections) when you have SWR readings below 1.5.

Do you have an antenna analyzer? or can you borrow one? If so, what is the impedance at the end of the coax? Both the resistive and reactive components please - just the SWR does not provide much information on how to advise you to proceed. You may be better off eliminating the coax entirely and running the window line all the way into the shack. 73, Don W3FPR djmd wrote: Hello, I have been trying to troubleshoot my antenna system, and have been trying to avoid the dreaded high swr post, but I've run out of ideas, so I'm turning here. First let me explain my system. 67' dipole fed by 16' of window line. That's connected to an Elecraft balun. From the balun, there's a short piece of coax going to a barrel and into the basement (through a piece of cement backerboard. From inside the basement, there is another piece of coax, about 12', connected to the barrel, and going up into the bedroom directly to a K2 with an autotuner. Before the K2, I was using a Yaesu FT840 with an MFJ tuner. After tweaking the window line length and the actual length of the dipole, I never really had a problem with SWR (well, according to what the MFJ was saying, which may or may not be totally accurate.) Usually 1.5:1 or under on all bands. With the K2/KAT2 in place, the SWR reported by the tuner is all over the place. The only one that gets less than 1.5:1 is 30m. Most bands are pretty random, anywhere from 3:1 to 7:1. However, on 20 and 40, it generally does not get below 9.9:1. I've tried 4 different lengths of coax between the barrel (inside) and the rig... 3', 6', 12' 20'. I've tried a couple different lengths between the balun and the barrel on the outside. When I attach the balun directly to the K2 I get 1.3:1 on all bands (most are 1:1.) With a short piece of coax between the rig and the balun, I get the same results. I've also attached my dummy load to the barrel on the outside of the house, and tested it from the shack, and I saw 1:1 no problem. I totally understand the concept that if A works and B works, A+B doesn't necessarily work. I understand it's a whole system. But I've tried so many different combinations of coax on each side, and don't understand why my SWR is basically infinity:1 on 20 and 40, when they seemed to match reasonably with the old system. I have not tried different lengths of window line between the dipole due to the fact that I had it perfectly trimmed for my old system. But I have plenty of it and would be open to trying anything. Just trying to get the most I can out of my modest 10W. :) Any suggestions would be appreciated! 73, Dave K8DJW __ 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 No virus found in this incoming message.

[Elecraft] [OT] High SWR on 20 and 40
Dave, Thanks for posting this. I'm going through the exact same exercise with my KX-1 KXAT1 and Icom703+. Glad to know I'm not alone. The Icom is able to tune just fine and when I switch the KX1 does not tune all bands – not on 40M. The KX1 tuner is optimized for shorter lengths of wire. I too wanted to use one antenna for both radios. I wonder if the K2 is optimized for a shorter wire? I find the more coax I insert between the 4:1 balun and radio the better the Icom tunes and performs and the opposite for the Elecraft -- it then loses 80, 40, 30 and barely tunes 20. It’s really odd. I get perfect SWR with a dummy load and KX1. I'll try a few things over the next few days per Elecraft. But will be very interested in what you find. Is the window ladder line 450 ohm? Does Elecraft give guidance on how the tuners are optimized? Eighth to quarter wavelength? I want to be sure as you do that the max power goes out.

[Elecraft] K3 initial resistance check on PPs at 1.9K ohm.
I have a low resistance on the power poles for my first resistance check and R36, but U12 and U13 are OK. I disassembled the sides and front panel, checked for missed masking tape or other issues,reassembled everything, and have repeatable low results. I verified resistance measurements by checking known resisters. Low12VDC PP connectors. Required: 3K ohms Measured: 1.85K ohms LowR36 and ground. Required: 150 ohms, measured: 100 ohms OKU12 and ground. Required: 500 ohms, measured: 1.85K ohms OKU13 and ground. Required: 150 ohms, measured: 2.50K ohms I think this is telling me I have I started with a multi-range DMM, but discovered an intermittent probe and had to use a single range (x1K ohm scale) analog meter. Will try to get a replacement tomorrow. Any suggestions for possible causes will be appreciated. This is my third kit (Rock-Mite, K1 and now a K3).

Re: [Elecraft] [K3] IF output
Ok so I decided to do the IF mod as the P3 will be ordered when it comes out and I'd like the increased sensitivity. I'm copying elecraft and K3 support cause I wanted to ask a simple question (as well as share the results). First my question, I didn't have any 13K ohm resistors in 0805 size. So I put an 0603 resistor on the same pads. Will this be ample or should I replace it with an 0805 for power rating reasons? I made measurements before and after the modification and collected results which I figured I'd share. Signal Generator was a Rhode and Schwartz (sp?) model number unknown. This signal generator was uncalibrated. However the spectrum analyzer I was using was a very recently calibrated N9020A which our cal report gave a clean bill of health and an absolute accuracy of 0.009dBm at -50dBm. Agilent didn't specify the accuracy at -70 but it was getting tighter as the amplitude went lower. I did not engage the preamp in the analyzer. I was making my measurements at -70dBm as its a common ham amplitude. I injected the signal at 7.040Mhz (cause I use that w/ my XG2 a lot) @ -70dBm. This input was verified on the spectrum analyzer at the end of my cable to calibrate cable losses out of the system. I then measured the output at the IF OUT port at 8.215Mhz. Before PreAmp off: -88.2dBm PreAmp on: -77.0dBm After PreAmp off: -77.9dBm PreAmp on: -66.9dBm Looks like there is a tad bit of loss with the PA off (7.9dB) but then again there is 3.1dB of gain with the PA on... Hopefully this jives with intended results. If not hopefully its a useful data point.

Re: [Elecraft] KFL3B-FM
