I wonder if what you are experiencing is simply the result of your K3's S meter being adjusted to read high on noise, coupled with the fact that its calibration results in something close to the standrard 6dB per S-point? I would suggest that you perform the S meter calibration procedure described in the manual. I am not familiar with the FT-1000MP but with many radios the S meter basically reads the AGC voltage and it takes a significant signal to shift it at all after which it shoots up at about 2dB per S point until it reaches the S9 level. - Julian, G4ILO.

Re: [Elecraft] Noisy K-3 Receiver
Hi Dick, I have both a K3 and FT-1000MP. I agree that the K3 can have a somewhat noisy behaviour leading to listening fatigue. I have the impression that the various F/W versions in the past gave different AGC behaviour influencing the noisiness. I played quite a while with the AGC SLP and AGC THR parameters in the config menu (TECH MODE ON !!). I am not behind the rig right now, but I remember decreasing the SLP and increasing the THR parameter tend to give a more old-fashioned analog listening experience. If you play a bit with these parameters you'll find out whether you can make your K3 sound more to your linking. In any case, on the weak signal side I can hear equally well on both radios. On the loud signal/crowded band side the K3 is much better, also due to the fact that I have both 500 and 250Hz roofing filters (which I let kick in at 650 and 350Hz respectively, something I can recommend to everyone to try). -- Enno, PF5X K3 #1263 RLVZ wrote: Hi Guys, I'd appreciate your thoughts as to why my K-3 receiver is so noisy.

Re: [Elecraft] Noisy K-3 Receiver
Dick, You are right about the s-meter of the FT1K. Under S8 it cannot be trusted. That is a fact. When I measured this on my MP a signal drop op 3 s-points resulted in going from s8 to s1 or so on the meter, so that's about the same as you see with yours. About the noise, I have done a comparison this morning. Both rigs sound different but my impression is that the rigs hear equally well. With the K3 on default settings, its produces a sound that I do not like. I tailored the RX audio with the RX-equalizer and it sounds more pleasant to my ears now. Setting the IF filtering takes care of the rest. Try playing around with those tools and see (hear) what you get then. 73 Arie PA3A __ 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] KPA100 another issue
Jerry, Have you done the KPA100 wattmeter balance (C1 adjustment) followed by the forward power calibration (R26)? If not, the KPA100 may be putting out a lot more power than indicated by the K2. If you do not have a good null on the C1 adjustment, you may as well stop and resolve that problem before attempting to go any further, it is a critical first step. Most likely causes for a failure to null are a problem with T4 or D16, D17 orientation or soldering problems in the area of T4. 73, Don W3FPR n0jrn wrote: Well, doesn't seem to my weekend. :-) While checking the output of the KPA100 ( during test and alignment ) completed the bias adjustment and began the transmit test.

Thanks Brian - the improvement in AUTO is very evident in my limited use so far. Really looking forward to the software for computer display! Brian Broggie wrote: Hot news! The latest W2 firmware rev (0.92) is now available on our ftp site. The easiest way to get it downloaded into your W2 is with our Elecraft W2 Utility program, available in three flavors (PC, Mac, Linux). Check out the Elecraft website for all the details! This new W2 firmware version has the following cool features... First, a fix: *SWR LED's FLASH RANDOMLY WHEN A SENSOR IS CONNECTED:* This turned out to be caused by corrupted data in EEPROM. This version checks for this and will correct it by restoring the data to default settings. And then some enhancements: SENSOR CALIBRATION VALUES EXPANDED: The calibration data for the Sensors is now saved both by Sensor type and the connector used by the Sensor. Among other benefits, this allows you to calibrate two of the same type of Sensors independently. FURTHER IMPROVEMENTS IN AUTO RANGE DISPLAY: We are continuing to improve the LED display in the Auto mode. In addition to editing algorithms, we are setting the LED and Serial Data Output modes to default as PEP, rather than Average Power. This can be changed at any time using the M (LED's) and N (Serial Data) commands We hope this latest version makes the W2 an even more useful and enjoyable wattmeter for your shack.

Re: [Elecraft] Noisy K-3 Receiver
G'day, The simple fact is that the faithful will always suggest that the K3 hears more, is more sensitive or is more transparent to band noise etc etc. Also you have to fiddle with the AGC, PRE, ATT and RF gain whereas other radios just sound nicer out of the box. I don't have a problem with fiddling with AGC and equaliser parameters to tailor the receive to my liking, but to have to do it to make it sound acceptable is another thing altogether. There is an often referred to AF filter module which installs on the main DSP board and apparently cuts out a lot of unnecessary high frequency audio. Sadly though often referred to it just isn't being made available despite very positive comment from some of those who have field tested it. The KAF2 filter for the K2 made all the difference in the world to listening to SSB.

Re: [Elecraft] Noisy K-3 Receiver
CONFIG: AGC THR may be set too high. Try a lower setting. I agree with Bill. He may also want to experiment with other AGC settings like AGC-F, AGC-S, AGC SLP and AGC HLD and AGC DCY. I found exactly what was described until I changed the AGC threshold/slope and equally important, the AGC recovery times to less aggressive values. I suspect that aggressive AGC values (even in default) may be causing the perceived increase in noise. He may want to prove to himself that the K3 is quite listenable with substantial audio dynamic range by changing to less aggressive AGC values. Then, increase accordingly. The default values are specified in the owner's manual so there's always the ability to re-set values if originals are forgotten. My AGC recovery times are set for minimum and for me, that's adequate, even under the fast setting. On some professional DSP-based audio processors, manufacturers have taken all the processing values, combined them into a single less/more virtual control so that all processing parameters work in tandem with each other. This works well for the person first opening the box and having a single control to get you 90% of the way there. Then, optimize the individual controls to best match various operating conditions. In the case of the K3, that's something like 8 menu controls dedicated to AGC, including the AF limiter function. Not everyone who purchases a transceiver is adept at AGC management.

[Elecraft] [K3] Diversity receive with limited space and RX Antennas
Greetings; I've researched the posts on this board regarding diversity receive in general, but have not found much information regarding the benefit (or lack thereof) of diversity receive with limited space and limited RX antennas. I'm considering adding the 2nd RX to my K3 for this purpose. I am on a small 1/4 acre lot, with a 38' tower roughly in the center of the lot with a tribander at the top. I have a G5RV in an inverted vee configuration with the apex near the top of the tower, and the ends running to opposite corners of the lot. I also have a multiband vertical, ground mounted with buried radials, about 25' from the tower. I may try adding a low (6' high) resistance-terminated receive antenna running around a portion of the yard. It will be close to the vertical at two points. Obviously, I'll have to configure an opto-MOS or something similar to disconnect the RX antenna when I'm transmitting, since my antennas don't have much physical separation. Does anyone have experience using diversity RX with a similar configuration? The addition of a 2nd RX with filters becomes fairly expensive- is it worth the cost in this antenna-limited situation? Thanks, and Happy Holidays.

Re: [Elecraft] K3 - PowerSDR-IF communication issue
Bill - My setup is K3, Clifton Labs buffer amp, EM0202. It wasn't plug and play for me, but it works great now. I found the info in Larry Phipps manual for setup and config of PSDR-IF extremely helpful. It's found on the Telepost Home page http://www.telepostinc.com/ Scroll down the home page to Setup and Config manual for PowerSDR-IF v1.19 / LP-Bridge v0.9976 betas - and open the .pdf. Larry's instructions assume you will be using the LP Pan instead of a Softrock, so your global offset and center frequency entered in the the Setup IF / IF Frequencies tab will be different than what he suggests. I use a global offset of -1710 and a center frequency of 8193500. Make sure you use the patched version of PSDR-IF v 1.19.0.2 ( I can email it to you) Some believe a USB to serial cable with FTDI chip will prevent some problems.

Re: [Elecraft] Noisy K-3 Receiver
Dick: You gave us the version of the K3 Utility. What version of firmware is in the K3. You will need to have the K3 Utility on and the K3 on with the pc connected to the K3. It should then show up in the tab for firmware below the section labeled Firmware version. Click on Check Versions Now If you see dashes in Installed.. column your PC is not talking to the K3. If much lower than 3.xx it is way out of date. Present version is 3.68. Click on Send all Firmware to K3 if the K3 utility shows less than 3.68 installed. You can also determine the version of the K3 Firmware by holding down the MENU button (CONFIG) on the K3 and selecting FW REVS with the B VFO knob. You may need to also rotate the A VFO knob to select uC so that it shows the main microprocessor FW version. KE0X RLVZ wrote: Hi Guys, I'd appreciate your thoughts as to why my K-3 receiver is so noisy. I'd really like to make this radio perform. The radio is Serial #603F (factory model) running 1.2.10.27. I purchased the unit from the original owner a couple of months ago so I don't know if it's always been this noisy but I do know it was the same before I recently updated software to 1.2.10.27. The radio is in immaculate condition and was never used mobile or bounced around. (it's a beautiful radio that looks like new!) I say the receiver is noisy based upon listening to dozens of different signals on: 40/20/15 m. and by doing numerous A/B comparison tests. The comparison tests were done with the K-3 Pre-Amp turned Off. (and tried with ATT on and off but mostly on to reduce noise). Radio 1: Yaesu FT-1000-MP w/AF Mod. A signal is peaking S-8 and with the no signal noise level is averaging S-1. Therefore, the signal is peaking aprx. 7 s-units above the noise based upon the MP s-meter and the signal sounds loud and is way above the noise level. Now I switch to the K-3: Radio 2: K-3 tuned to the same signal with PreAmp Off and is peaking S-7 but the no signal noise level is noisy S-4 to S-5. Therefore, the signal is peaking only about 2 or 3 s-units above the noise level based upon the K-3 s-meter. The result is that the MP has aprx. a 4 s-unit S/N ratio advantage. Thoughts: I realize that all s-meters read differently and the fact that the MP s-meter shows a 4 s-unit stronger signal above the noise level doesn't mean alot. But the fact is that the signal on the MP sounds MUCH louder with alot more headroom above the noise level. The K-3 receiver sounds so noisy even with the S-7 signal that it isn't enjoyable listening to and that's why I ran the comparisons because I couldn't stand all the noise. Switching on the K-3's NR, ATT, and/or adjusting the RF Gain does help some but the signal still sounds noisy compared to the MP. Based upon Reviews of the K-3 I believe that I must have an unusual K-3 noisy receiver problem. I'd sure appreciate your ideas on how I can get a better S/N ratio on my K-3.

[Elecraft] [K3] Diversity receive with limited space and RX Antennas
Hi Jason: Try a less expense approach first. If you don't already have it, add the KXV3A, I/O module, for $110 that will permit you to use a separate receive antenna on your main RX. If you like the performance of your receive antenna then you will be in a better position to determine, on your own, if diversity receive will be beneficial or not. And even if you do get the sub RX, the KXV3 is still highly useful for those times when you want to use your RX antenna on the main RX. 73, Mike K2MK AC7JW Wed, 16 Dec 2009 10:31:08 -0800 Greetings; I've researched the posts on this board regarding diversity receive in general, but have not found much information regarding the benefit (or lack thereof) of diversity receive with limited space and limited RX antennas.

Re: [Elecraft] Fw: Hardware Differences K3
We started shipping the current DSP boards, Rev C, approximately March 6th, 2009. Any K3 DSP board Rev C or later will have the extended low end audio frequency response h/w enhancement. This corresponds approximately to K3 serial number 2800, plus or minus 10-20. Since assembled -Fs and kit K3s flow through different manufacturing paths, there is a slight variance in s/n for the phase-in. If in doubt, check the DSP board Rev as noted above. These changes basically added additional h/w low end frequency response below 300 Hz. You need to also have the latest K3 f/w to take advantage of this. Of course, you can also tailor (and limit) your RX and TX response via the K3's IF Shift and B/W controls and by using the TX and RX Equalizer entries. A picture of the Rev label location on the DSP board and additional info is at: http://www.elecraft.com/K3/mods/dsp_rev_c_information.htm (The 'C', or later, revision letter at the bottom of the label is what is important.) We have added to our parts and mod kits page an option, K3DSPUPGD to swap out your current DSP for one upgraded to the latest Rev C changes. The cost will be $69.00 plus shipping.

Re: [Elecraft] K3 Amplifier Keying
Phil, You may want to isolate all three key lines using one of the many keying buffers available. At an absolute minimum, consider using three steering diodes if only using a splitting RCA jumper cable from the K3 to the amps, using one diode (e.g., 1N4007 or if necessary, a Schottky type) for each amp key line from the K3 with all the cathodes combined together and pointing back to the K3 amp key line. The ne-plus-ultra solution for selecting one of three amps from one of three rigs may be available in the very near future from W8ZR... http://www.w8zr.com/homebrew/StationPro.htm Paul, W9AC - Original Message - From: Phil LaMarche plama...@verizon.net To: elecraft@mailman.qth.net Sent: Wednesday, December 16, 2009 4:28 PM Subject: [Elecraft] K3 Amplifier Keying My K3 will be keying 3 amplifiers144...50 and HF.

Re: [Elecraft] K3 Amplifier Keying
Phil, While it is likely the K3 KEYOUT can handle that with no problem, I would not try to just 'tie them together'. Reason, the open circuit voltage for each amp may be different, and that will cause current to flow from one amp to another. I would suggest using either a switch (hard to remember to change it) or make up a multi-keying circuit that is driven by the K3 and provides 3 isolated keying outputs. An inversion stage with a pullup resistor on the input followed by 3 HEXFETs (like the IRF830 or IRL620), each driving a separate amplifier would provide all the isolation needed, along with plenty of resurve current handling capacity for most any amplifier which uses a positive keying voltage. One could also drive such a circuit from the KEYOUT-LP from the ACC connector (max of 10ma current sink) and use the K3 KEYOUT to key yet another amplifier. 73, Don W3FPR Phil LaMarche wrote: My K3 will be keying 3 amplifiers144...50 and HF.

Re: [Elecraft] K3 Amplifier Keying
Phil, The closest you're going to get to plug-'n'-play amplifier isolation is by purchasing a commercial keying buffer, one for each amp and split the K3 key line three ways to the input of one of these devices. The output from each device would go to its own amp. For three devices that's USD $90-$180 depending on the model + the cost of cables. http://www.theheathkitshop.com/page13/page13.html http://www.radiobooks.com/products/svkr.htm http://www.ameritron.com/Product.php?productid=ARB-704 By contrast, three silicon diodes can be purchased with pocket change and can be easily inserted into RCA plugs with just a bit of soldering necessary.

Re: [Elecraft] Fw: Hardware Differences K3
Hmmm, no mention of the (hardware) AF low pass filter in the announcement quoted below... can Elecraft confirm/deny? There is no documentation of the K3DSPUPGD option on the order page, and nothing in the K3 Alerts, Enhancements and Application Notes page either. Bob NW8L On Wed, Dec 16, 2009 at 1:56 PM, Steve Ellington n...@carolina.rr.com wrote: We started shipping the current DSP boards, Rev C, approximately March 6th, 2009. Any K3 DSP board Rev C or later will have the extended low end audio frequency response h/w enhancement. This corresponds approximately to K3 serial number 2800, plus or minus 10-20. Since assembled -Fs and kit K3s flow through different manufacturing paths, there is a slight variance in s/n for the phase-in. If in doubt, check the DSP board Rev as noted above. These changes basically added additional h/w low end frequency response below 300 Hz. You need to also have the latest K3 f/w to take advantage of this. Of course, you can also tailor (and limit) your RX and TX response via the K3's IF Shift and B/W controls and by using the TX and RX Equalizer entries. A picture of the Rev label location on the DSP board and additional info is at: http://www.elecraft.com/K3/mods/dsp_rev_c_information.htm (The 'C', or later, revision letter at the bottom of the label is what is important.) We have added to our parts and mod kits page an option, K3DSPUPGD to swap out your current DSP for one upgraded to the latest Rev C changes. The cost will be $69.00 plus shipping. Order placed via this page will start shipping approximately in 4 weeks, around Nov 9.

[Elecraft] K2 Spot Signal Strength
Hello, I don't have any trouble using the K2 SPOT switch when using the K2 as a transceiver. However, when using the K2 as a CW transmitter only (with a homebrew T/R switch and an older boatanchor receiver) the K2 SPOT function doesn't seem to put out any kind of signal I can hear in the boatanchor receiver, so I can't really spot the K2. I only use the K2 in this configuration occasionally, but wonder if anyone else has a recommendation for CW spotting with an external receiver? Is there a way to adjust SPOT strength? --Ed-- __ 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] K2 Spot Signal Strength
Ed, There is no easy way to do that. The K2 does not emit any RF when using the SPOT button, it just injects a tone into the audio. You could switch the K2 to a dummy load and tap the key, - don't forget to switch the K2 back to the antenna before transmitting if you want to make any contacts. 73, Don W3FPR Ed G wrote: Hello, I don't have any trouble using the K2 SPOT switch when using the K2 as a transceiver.

Re: [Elecraft] Noisy K-3 Receiver
I would like to hear more about the AF Filter Module. I didn't have any initial interest in the DSP board upgrade but maybe I would reconsider if I knew what the AF Filter Module did. Maybe someone who has upgraded could comment. 73, Mike K2MK Lyle Johnson Wed, 16 Dec 2009 09:45:58 -0800 There is an often referred to AF filter module which installs on the main DSP board ... My understanding is that this is part of the DSP board swap upgrade, and is in currently shipping K3s.

Same here. I ordered and got confirmation of payment but no hint of if or when it would ever ship so I sent an inquiry and Lisa said about 2 weeks. Maybe by Christmas?

[Elecraft] K3 Rev C +AF filter
Well I for one missed the AF filter part of the DSP upgrade. Not all K3 owners spend time on the internet and Elecraft web site in particular. So if anyone does know exactly what the AF filter does to enhance the receiver DSP over that what we have prior to it's release, would certainly help those of us who are in two minds about spending money to improve a radio costing very close to 5 thousand dollars. For those owners outside the US, ordering anything from Elecraft can become a considerable expense with shipping charges etc. 73's Gary Sent via BlackBerry® from Telstra __ 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] Regarding a carrying box for the K3
Back on November 13th, Dave, K1WHS, reported that he'd bought a military surplus aluminum box (item #138401) from www.colemans.com, and that he'd managed to satisfactorily shoehorn his K3 into the box. Following Dave's lead, I ordered three (3) of the boxes, one for myself, and two for other locals who also had K3s. I waited several weeks for delivery of the boxes, but to no avail. I called Coleman's and found that someone had dropped the ball... having taken my order, but failed to process it any further. The boxed went out that day and were received three days later. Today I donned my surgical mask and latex gloves, picked up the electric carving knife, and had my way with the energy-absorbing foam in one of the boxes. The 'surgery' went well, and much more swiftly than I'd have ever expected. I now have a very nice, and certainly VERY STURDY, aluminum carrying box for my K3, with the K3 firmly, and safely cradled within it's loving arms. If you're interested in seeing the final product, drop by my web site at www.n0ss.net and go to the K3-specific page. There you'll find a small PDF giving all the gory details. I think the purchase of the box is going to be very well worth the price AND the wait.

Re: [Elecraft] Elecraft W2 Interface Software now available.
Now this is the real deal! With the small window one can just leave it up all the time. I like having the reflected power in watts and SWR both. Now you can get an exact numerical power reading so you get the reading as accurate as the W2 circuitry can produce which Eric says exceeds the specification.

Re: [Elecraft] Regarding a carrying box for the K3
Hi Tom, Someone on the Elecraft reflector ordered the plastic box variant and was going to report back on that. As of yet I have not heard anything, but I suspect it is just as serviceable and even lighter than the aluminum cases that I bought. I looked at your website and it looks like you carved up the foam just about the same way that I did. Once you use a serrated knife, you can get quite professional results. I even used the cutout foam to raise the K3 as you did. (Great minds think alike) I was debating whether to hack up the foam in the top of the case for headphone storage, but decided for now to just keep the K3 in there by itself. I opted to flip the top foam over, so that it has no cutouts visible in it at all now. I have a remote hamshack about a half mile behind my house up a very bumpy woods road. I am constantly ferrying gear back and forth and these transport cases fill the bill nicely. Now I can throw the cases in the back of the truck and not worry that someone will drop a few turnbuckles or a power supply on my precious radio!! The case is ideal for a Caribbean mini DXpedition during the winter months too. I like the fact that it is waterproof. Yeah, I tested it with a garden hose. My brother also bought a metal case for his K3, but his unit had some stale foam that appears to need replacing. You can find new foam rubber at places that deal with upholstery refinishing etc. 73 Dave K1WHS - Original Message - From: Tom Hammond n...@embarqmail.com To: elecraft@mailman.qth.net Sent: Thursday, December 17, 2009 2:40 AM Subject: [Elecraft] Regarding a carrying box for the K3 Back on November 13th, Dave, K1WHS, reported that he'd bought a military surplus aluminum box (item #138401) from www.colemans.com, and that he'd managed to satisfactorily shoehorn his K3 into the box.

[Elecraft] Noisy K-3 Receiver
Dick, I've had the same experience as you describe. You will get some explanations here on the reflector that sort of make sense so I will not try to repeat them. What it comes down to for me is there is less usable S meter range and amplified background noise to contend with. A great receiver but having to listen to that background noise is disquieting. I think the noise/S meter relationship needs a solid review from engineering aimed at putting a bit of a knee at the bottom of the scale and in the process dropping the apparent noise level. A supersensitive receiver is great but when all it's doing is digging out noise it's of little value. I agree NR and related controls help a bit on the noise but it doesn't address the underlying situation. Many of us over-the-hill folks have a sensitivity to noise that younger people don't have so it may be hard for them to understand and appreciate our concern. Have a good day and 73. Jim, W0EM Date: Tue, 15 Dec 2009 23:44:26 EST From: r...@aol.com Subject: [Elecraft] Noisy K-3 Receiver To: elecraft@mailman.qth.net Message-ID: be9.65ac7dd1.3859b...@aol.com Content-Type: text/plain; charset=US-ASCII Hi Guys, I'd appreciate your thoughts as to why my K-3 receiver is so noisy. I'd really like to make this radio perform. The radio is Serial #603F (factory model) running 1.2.10.27. I purchased the unit from the original owner a couple of months ago so I don't know if it's always been this noisy but I do know it was the same before I recently updated software to 1.2.10.27. The radio is in immaculate condition and was never used mobile or bounced around. (it's a beautiful radio that looks like new!) I say the receiver is noisy based upon listening to dozens of different signals on: 40/20/15 m. and by doing numerous A/B comparison tests. The comparison tests were done with the K-3 Pre-Amp turned Off. (and tried with ATT on and off but mostly on to reduce noise). Radio 1: Yaesu FT-1000-MP w/AF Mod. A signal is peaking S-8 and with the no signal noise level is averaging S-1. Therefore, the signal is peaking aprx. 7 s-units above the noise based upon the MP s-meter and the signal sounds loud and is way above the noise level. Now I switch to the K-3: Radio 2: K-3 tuned to the same signal with PreAmp Off and is peaking S-7 but the no signal noise level is noisy S-4 to S-5. Therefore, the signal is peaking only about 2 or 3 s-units above the noise level based upon the K-3 s-meter. The result is that the MP has aprx. a 4 s-unit S/N ratio advantage. Thoughts: I realize that all s-meters read differently and the fact that the MP s-meter shows a 4 s-unit stronger signal above the noise level doesn't mean alot. But the fact is that the signal on the MP sounds MUCH louder with alot more headroom above the noise level. The K-3 receiver sounds so noisy even with the S-7 signal that it isn't enjoyable listening to and that's why I ran the comparisons because I couldn't stand all the noise. Switching on the K-3's NR, ATT, and/or adjusting the RF Gain does help some but the signal still sounds noisy compared to the MP. Based upon Reviews of the K-3 I believe that I must have an unusual K-3 noisy receiver problem. I'd sure appreciate your ideas on how I can get a better S/N ratio on my K-3.

Re: [Elecraft] Regarding a carrying box for the K3
For me shipping was about $18 which I thought was a bit too much to ship. So, I went on eBay today looking for a case/container for my K3. I found a padded case for a projector that I think will work for my needs. But, in my search I found the same aluminum case without the foam for $32.99 with free shipping.

Re: [Elecraft] Fw: Hardware Differences K3
I'm wondering the same thing myself as I've held off on the upgrade. I couldn't really come up with any outstanding reasons to improve something I didn't believe needed improving. Anyway, I'm open to reasons. If someone can give me a good one, perhaps I'll swap the boards out. 73, James K2QI -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of k...@aol.com Sent: Wednesday, December 16, 2009 4:05 PM To: n...@carolina.rr.com; elecraft@mailman.qth.net Subject: Re: [Elecraft] Fw: Hardware Differences K3 Thanks for re-posting the info.

Re: [Elecraft] Noisy K-3 Receiver
Ditto here as well, and that's comparing my K3 #2730 to a stock FT-1000. Wow, I thought it was just me. I never gave it much of a second thought, and just attributed the difference in noise floor/signal peaks to a more sensitive receiver. I've worked long pileups from 4U1UN and the FT-1000, and I don't recall ever having as much noise-related fatigue as I get when I use the K3. Please don't get me wrong; I'm not bashing the K3. It just seems the K3's noise characteristics seem stronger and perhaps a tad harsher than what comes out of the Yaesu. I hope that makes sense... 73 de James K2QI -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Harris Sent: Wednesday, December 16, 2009 10:33 PM To: Elecraft Email Subject: [Elecraft] Noisy K-3 Receiver Dick, I've had the same experience as you describe. You will get some explanations here on the reflector that sort of make sense so I will not try to repeat them. What it comes down to for me is there is less usable S meter range and amplified background noise to contend with. A great receiver but having to listen to that background noise is disquieting. I think the noise/S meter relationship needs a solid review from engineering aimed at putting a bit of a knee at the bottom of the scale and in the process dropping the apparent noise level. A supersensitive receiver is great but when all it's doing is digging out noise it's of little value. I agree NR and related controls help a bit on the noise but it doesn't address the underlying situation. Many of us over-the-hill folks have a sensitivity to noise that younger people don't have so it may be hard for them to understand and appreciate our concern. Have a good day and 73.

[Elecraft] K3 Noise on receive
H...I have a very low tolerance for noise, tininitis is a big reason, however I have been able to get good low noise receive by adjusting the weapons the K3 has installed. I don't use the internal speaker of course, but either my external speaker or headphones do not fatigue me and I recently spent 24 hours at the helm steering my way through pileups during a recent contest. Receive quality appears to vary greatly from one owner to the next as each of us have our own way of operating and settings for one person may not suit the majority . 73's Gary Sent via BlackBerry® from Telstra __ 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] Noisy K-3 Receiver
Hi Mike, I've fiddled with all of the AGC, PRE, ATT, RF, and DSP options on my K3, and still experience a relatively high noise floor - at least compared to an FT-1000 side by side. I never gave it much thought until these subject came up on the reflector.

I don't have a problem with fiddling with AGC and equaliser parameters to tailor the receive to my liking, but to have to do it to make it sound acceptable is another thing altogether. There is an often referred to AF filter module which installs on the main DSP board and apparently cuts out a lot of unnecessary high frequency audio. Sadly though often referred to it just isn't being made available despite very positive comment from some of those who have field tested it. The KAF2 filter for the K2 made all the difference in the world to listening to SSB.

Re: [Elecraft] Fw: Hardware Differences K3
Jim, Replacing the DSP board isn't that difficult; remove the front panel, and you'll see the DSP board attached to the rear of the FP via a couple of stand-offs and some screws. If you take your time, it could be done in under 30 minutes. If you ordered your K3 assembled or have never taken the FP off before, download the assembly manual from the website and you can see the required steps beforehand. 73 de James K2QI -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Miller KG0KP Sent: Thursday, December 17, 2009 12:54 AM To: Steve Ellington; elecraft@mailman.qth.net Subject: Re: [Elecraft] Fw: Hardware Differences K3 Is this a mod that can be done in the field?
