Re: [Elecraft] K3: Why can't I use my 1.8kHz filter for SSB TX?

The AM transmit filter must be 6 kHz and the FM transmit filter must be 13 kHz. Any other settings will result in failure and a ERR TXF (Error TX Filter) message. See the Errata sheet that shipped with your K3. 73, Don W3FPR To the best of my ability to discern, this does not indicate the reason for the limitation. In fact, the phrase until further information and the fact that ESSB uses a different filter than traditional SSB indicates to me at least the possibility that there may be firmware reasons for this limitation (like BFO alignment on TX and RX), not that there aren't also possibly hardware reasons (like carrier rejection, etc.). If someone knows the theory of the radio's operation well enough to help me understand the limitation, I would like to be enlightened. So yes, I did look for the answer in the reflector archives and no, this is not a request for Elecraft to take valuable time out from their other activities to react to my personal wish list. __ 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 and W2IHY EQ Plus!
Hi all! Anyone using a W2IHY EQ Plus with the K3?

[Elecraft] Hybrid Power Supply--is this a bad idea?
I've been running my CW only K2 using the hybrid power supply designed by Fred (K3GQ) at Gamma Research. This tiny power supply packs a big punch because it is loaded with about 5 farads of capacitance. The capacitors provide the high current surges needed during the high-power portions of the duty cycle, but recharge during low-power portions of the duty cycle. You can read more about this thing at http://www.gammaresearch.net/hps-1a.html. In all ways, I've found this power supply to be an excellent piece of work (and I haven't noticed any RF hash). Now that I've added the KPA100/KAT100, in a separate EC2 enclosure, I'd like to continue to run this power supply. But I'm wondering if anyone thinks this is a bad idea. The potential problem lies in the fact that the power supply is in a sense not well regulated. While it never provides a voltage 13.6 V, the voltage sags on TX as the capacitors discharge. Fred has designed this power supply so that it can power most rigs at 100W (CW or SSB, but my work is only CW) before the voltage sags below ~12V for normal CW/SSB duty cycles. I've measured the voltage sag at the output of the power supply with an oscilloscope and find that when I send CW at 15 WPM into a dummy load at 100W with my K2, the power supply sags as low as about 11.9 volts on TX. Of course, the voltage recovers quickly between the dahs and dits as the caps recharge, but again, never even momentarily goes below ~11.9 volts. Also, as I noted above, the power supply never provides a voltage 13.6 volts. I could acquire and attach an o-scope trace, if that would help anyone make up their mind. I'm wondering how this rapid supply voltage variation might affect the K2? I've not noticed any problems, but I'm not that bright.

Re: [Elecraft] Hybrid Power Supply--is this a bad idea?
Since you're using CW, I think the only possible ill effect of the voltage variation could be a pulling of one of the VFOs causing a chirp on your signal, if the K2 voltage regulation isn't good enough to take care of it (which it probably is.) The best way to be sure is just to listen to your signal in another receiver. - Julian, G4ILO.

Re: [Elecraft] K3: Why can't I use my 1.8kHz filter for SSB TX?
The key problem is that when you want to use other than a 2.7 or 2.8 kHz filter for receive, you must still tie up one of the remaining 4 filter slots with either the 2.7 or 2.8 kHz filters in order to transmit. If there were 7 or 8 filter slots in the radio, or one slot dedicated to transmit, this would not be a problem. In my case, I have a 200, 500, 1000, 2.1 and 6 Khz filter installed.

Re: [Elecraft] Hybrid Power Supply--is this a bad idea?
Key-down tuning for QRO is a no-no, as is RTTY. They spec the power supply at 22 amps -- 25% duty cycle -- or 5 amps continuous. 12.5 volts times 5 amps is 62.5 watts. If one figures in the usual 50% efficiency of transistor rigs, that's 31 watts brick on key, a figure that will be need to set as a tuning power limit in an auto-tuner rig. Probably better to say 25 watts continuous and enough to drive an amp that drives with 50-60 watts, IF the amp can be tuned at half power. Otherwise, tuning the amp would require a pulser or string of dits. For a suitcase situation it would be ideal, just back the power off. What I don't understand is why they didn't double up on the cap, upsize a few things and get it to 22 amps 50% duty cycle. But in its current miniature version, I've toyed with the idea of deconstructing the power supply and reconstructing it inside an EC2 with a KPA100 as a companion to my going-to-stay-that-way 10W battery K2. 73, Guy K2 #1239 K3 #1239 On Mon, Jan 25, 2010 at 7:55 AM, Douglas Furton d...@inbox.com wrote: I've been running my CW only K2 using the hybrid power supply designed by Fred (K3GQ) at Gamma Research.

Re: [Elecraft] K3: Why can't I use my 1.8kHz filter for SSB TX?
I see where you are coming from, but with a 2.1 why bother with the 1000 roofing filter (that's a question, not a criticism), since for casual operation the DSP should suffice. But since you DON'T have a 2.7/2.8 installed, how are you tricking the system? You telling it that the 2.1 is a 2.7? Why do you have to remove one of the filters I want to use? In my lineup I have 250, 400, 1.8, 2.7, and 6. For casual CW I frequently use width at 800 (thus invoking the 1.8 roofer) around 500 Hz. For digital I use 2.7 width and let the computer watch the entire bandwidth. Some time ago I asked why one did not transmit CW through the narrow filter to limit bandwidth. I never quite got that answered. Some speculated that had to do with products of phase distortion in the narrow filters. I don't recollect an official answer. My personal *guess* at this point is that it has something to do with FCC type acceptance. 73, Guy.

Re: [Elecraft] Hybrid Power Supply--is this a bad idea?
What I don't understand is why they didn't double up on the cap, upsize a few things and get it to 22 amps 50% duty cycle... It should be possible to parallel another 5 Farad of C by adding a DC connector to the Gamma supply. For higher duty cycle operations, just plug the added C into the new DC jack. For lower duty cycle, the added C would be left unplugged. Real estate is pretty tight inside the Gamma supply. Probably the best attempt may be a coaxial DC jack and it cannot be accidentally reversed with the existing Molex output connector. The Gamma supply works very well with the K3 and the inclusion of more C would probably make it even better under higher duty cycle operations.

Re: [Elecraft] K3 and W2IHY EQ Plus!
Hello Goran, I use the W2IHY Dual Band Noise Gate with my K3 and am very happy with it. If you only want to adjust the audio spectrum you can always use the built-in TX EQ in the K3. However, I have never bothered to adjust the equalizer inside the K3. My primary goal was to eliminate the high level of background noise from my VHF amplifiers when I operate SSB mode. Before I had my K3, I used a Heil HC5 element with the W2IHY, but now I use the Heil Proset K2 headset with my W2IHY and K3. My mic setting on the K3 is for the Rear Panel (where I have the W2IHY plugged in) with no bias. This K3 setting is also the same setting I must use if use the HC5 alone (however, I must change the setting to add bias if I use the Proset K2 directly). I set the K3 option for the TX GATE to OFF. Back in 2008, I was excited to learn that Elecraft was incorporating an internal noise gate into the K3, since I had hoped it would permit me to get rid of the external W2IHY unit. However, when I tried to use the internal TX GATE built into the K3, I would always get reports of distorted audio. Since I went back to the old reliable W2IHY Dual Band Noise Gate (over a year ago), I have only received excellent audio reports. I have not heard any comments from Elecraft regarding plans to develop a more effective internal noise gate. Therefore, if your interest is in using a noise gate to produce quiet TX audio, I highly recommend the W2IHY unit. GL and VY 73, Lance On 1/25/2010 8:37 AM, Gordan Hribar wrote: Hi all!

Have you tried turning down the mic gain and working it close? Talking louder? Problems like this can be easily solved by inverse square law -- that is, loudness drops by 6dB each time you double the distance from the source, so bringing the mic MUCH closer to your mouth than to the noise source improves the signal to noise ratio a lot. You can also improve the signal to noise ratio by using a directional mic, like the one built into the Yamaha CM500 headset. Before I found the CM500, I used an EV RE11 mic. You can also reduce background noise by placing sound absorbing materials on walls and other surfaces in the general vicinity of the noise source. The fans on my Titan amps are a bit noisy, so I let them sit on a 2-inch thick piece of sound absorbing foam. That kills vibration-coupling of the noise to the operating bench. I work the mic at 1-2 inches, using nothing more than the EQ built into the K3, and critical listeners tell me there's no background noise. 73, Jim 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

My daughters (3yo and 7 yo) and I are continuing the K2 build. Both daughters are now capable of holding the soldering iron and the solder during soldering. They take turns now: one holding the solder and the other holding the iron. Both are sitting on my lap when soldering is done. Needless to say, the 7 year old is steadier than the 3 year old but both are capable. No obvious cold solders and Dad occasionally reflows the joint when suspicious. I am having them do only resistors/capacitors. No semiconductors. I haven't tried having the 7 year old hold both the solder and the iron at the same time but will try in the next few days.

Clamping on onto a cable simply adds that 150 MHz resonance to the common mode circuit. That's great if the RFI is on 2M, but next to useless if it's on 20M. To make a choke work on 20M, we must wind multiple turns through the ferrite to more the resonance down to 20M. For a typical ferrite clamp-on, that's about 5 turns. You can't do that on the boom, but you can do it on the cable.

Hello Lance. In addition to excellent built-in EQ, the K3 TX audio chain has a built-in noise gate that I find to be excellent at reducing or eliminating background noise on SSB. You might want to give it a go.

[Elecraft] Looking to build a better power supply from an old one
I have an old off brand linear power supply that is inop - it was a freebie. I would like to re-build it with a modern circuit as it was regulated with a zener and I would prefer an ic based regulator. The transformer is fine. I would like to find a circuit board I can populate with - parts. I can build a kit just fine but I'm lousy at breadboarding a circuit from a schematic. Does anyone know of a place I could find something like that for a 20 amp regulated linear supply? 73 Bill NZ0T -- View this message in context: http://n2.nabble.com/Looking-to-build-a-better-power-supply-from-an-old-one-tp4455950p4455950.html Sent from the Elecraft 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
[Elecraft] W2IHY/K3
Hello Gordan, I have the W2IHY connected to my K3 and it does a great job. It is not necessary, however. I bought the IHY to use with my Orion II and a very old dynamic microphone, a ElectroVoice EV664. The only reason I use the IHY with the K3 is that I can just reach behind the IHY and move one switch and be transmitting with the same mic on either the K3 or the Orion II. It is simply a matter of convenience, that's all. I have a very cheap computer gaming headset that I use also with the K3 and it sounds great...lots of DX/Contesting punch... Hope this helps... 73 Tom CX7TT __ 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 and W2IHY EQ Plus!
Hi Gordan, I originally used my K3 with a Heil Goldline and the W2IHY EQ box. I received great reports. But I needed some space on the desktop, so I pulled the W2IHY box, added the Heil PR781 mic and did virtually the same EQ tweak within the K3' menu. Same results, great audio reports, less clutter. The W2IHY is a great product and Julius is wonderful with his support. I'll add the IHY box to my backup rig and continue to benefit from it. 73, Terry, W0FM -Original Message- From: Gordan Hribar [mailto:t93x_gor...@yahoo.com] Sent: Monday, January 25, 2010 2:38 AM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 and W2IHY EQ Plus!

Re: [Elecraft] K3 and W2IHY EQ Plus!
Thanks for the suggestions about mic presence Jim. Yes, the mic on my headset is set so it is directly in front of my lips - as close as it can be without touching. The problem I have here is that the amplifiers are directly behind me, so the mic is also aiming that direction when I am talking into it. However, the W2IHY Noise Gate is extremely effective, works well, results in excellent audio reports and I am very pleased with the current setup. As far as I am concerned, I do not currently have any problems with my current setup. 73, Lance On 1/25/2010 5:23 PM, Jim Brown wrote: On Mon, 25 Jan 2010 15:40:17 +, Lance Collister wrote: My primary goal was to eliminate the high level of background noise from my VHF amplifiers when I operate SSB mode. Have you tried turning down the mic gain and working it close? Talking louder? Problems like this can be easily solved by inverse square law -- that is, loudness drops by 6dB each time you double the distance from the source, so bringing the mic MUCH closer to your mouth than to the noise source improves the signal to noise ratio a lot. You can also improve the signal to noise ratio by using a directional mic, like the one built into the Yamaha CM500 headset. Before I found the CM500, I used an EV RE11 mic. You can also reduce background noise by placing sound absorbing materials on walls and other surfaces in the general vicinity of the noise source. The fans on my Titan amps are a bit noisy, so I let them sit on a 2-inch thick piece of sound absorbing foam. That kills vibration-coupling of the noise to the operating bench. I work the mic at 1-2 inches, using nothing more than the EQ built into the K3, and critical listeners tell me there's no background noise. 73, Jim 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 -- Lance Collister, W7GJ (ex: WN3GPL, WA3GPL, WA1JXN, WA1JXN/C6A, ZF2OC/ZF8, E51SIX) P.O.

Re: [Elecraft] Hybrid Power Supply--is this a bad idea?
Key-down tuning for QRO is a no-no, as is RTTY. They spec the power supply at 22 amps -- 25% duty cycle -- or 5 amps continuous. 12.5 volts times 5 amps is 62.5 watts. If one figures in the usual 50% efficiency of transistor rigs, that's 31 watts brick on key, a figure that will be need to set as a tuning power limit in an auto-tuner rig. Probably better to say 25 watts continuous and enough to drive an amp that drives with 50-60 watts, IF the amp can be tuned at half power. Otherwise, tuning the amp would require a pulser or string of dits. For a suitcase situation it would be ideal, just back the power off. I have been using the small supply with my K3 all the time. No distortion or clicks heard or reported on SSB and CW at 100 watts out. A very neat package when combined with the SPE 1KFA lineal amplifier, that needs so little input power that even RTTY at 500 W out is of no consequence to the Gamma Research power supply limitation. 73 Reinaldo, YV5AMH __ 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: transmitted RF feedback with condenser mics?
Hi Jim, Well, the ferrite bead may not be self-resonant on 20 meters, but it still provides SOME impedance to the common-mode current. I found experimentally that it did help. And lots of people use these snap-on beads to good effect even in situations where multiple turns (which of course would be better) are not practical.

Clamping on onto a cable simply adds that 150 MHz resonance to the common mode circuit. That's great if the RFI is on 2M, but next to useless if it's on 20M. To make a choke work on 20M, we must wind multiple turns through the ferrite to more the resonance down to 20M. For a typical ferrite clamp-on, that's about 5 turns. You can't do that on the boom, but you can do it on the cable. The original poster of this question emailed me this morning telling me he had solved his problem by re-cabling the coax between his rig, amp, and antenna switching, so the source of his RF was probably a badly terminated coax connector. 73, Jim 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 __ 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: transmitted RF feedback with condenser mics?
Brian, I know a guy in Sonoma, CA, whose porch lights come on (dimly) when he transmits on 160!! Fortunately, my main problem (on 20 meters) seems not to touch the DSL, WiFi, etc. system. Fingers crossed. I think one of the hidden problems we all have is resonance with phone lines, household wiring, or metal weatherstripping, etc. The RF may be coming directly from the antenna, and no amount of RF proofing in the shack is going to help much then. Maybe move the antenna? Maybe try putting 0.01 RF-bypass capacitors ACROSS the phone line at the jack where the DSL modem plugs in. Probably wouldn't hurt the DSL or POTS signal much, and might bypass the RF. Maybe it isn't even common mode.

Re: [Elecraft] Hybrid Power Supply--is this a bad idea?
Hi, The Gamma is my primary PS on my K3 (don't own a K2). Never had a problem with it since I've been using it almost a year now. That being said, you have to understand its limitations: SSB, it's great and gets out 100w; AM, reduce power down to 70w-80w; Digital modes some high speed CW can drag it down if you don't lower your ERP a bit. You might try uping your CW speed if you can :drunk:! Once again this is with my K3, K2 might be different. The dual voltage capability of the Gamma was one of its biggest selling points for me. A side note - 25 amp breakers/fuses are a good idea to install on the power lines to the radio since there is no breaker/fuse in the unit itself. - You're gonna have to answer to the Coca-Cola company. -- View this message in context: http://n2.nabble.com/Hybrid-Power-Supply-is-this-a-bad-idea-tp4453756p4456890.html Sent from the Elecraft 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

[Elecraft] Fw: K2 PA repair kit
Afternoon all: K2 #6272 is alive and well once again. Had a heck of a time getting the Q7 Q8 installed. Kept seeing a short to the heat sink. Turned out the corner of the tab on Q7 had a raised area and a slight sharp spot that was cutting through the thermal pad and shorting to the heat sink when the screw was tightened in the tab. Fixed that and all back together. 14.5 watts out on 40 meters into a dummy load with 2.42 amps draw. Much better. 10 meters shows 12 watts out with 3.15 amps draw. RX and TX working fine on all bands and the KAT2 doing it's job just fine. K60XV is not on the board at this time. Jumpers are in place for now. I did test voltage on the base of Q7 Q8. Both showing .63 volts while tuning. Now that the base K2 is up and running, it's time to tackle what ever ails my K60XV.. No solder bridges at 8T so I'm diggen in to see what gives. Thanks to all for your suggestions / help: 72Jerry N0JRN The K60XV should not reduce the base voltage at Q7 and Q8. BUT, since it is, remove the K60XV, put a jumper wire from pin 3 to pin 5 on J13 and stick the leads of a small value capacitor (4.7 pF is ideal) into pins 1 and 3 of J15. The K2 should operate normally except for 60 meters with that jumper/cap combination in place. The 0.64 volts is within range, even though it is a bit on the high side of what I normally like to see. As far as the K60XV problem, if your K2 has a serial number less than 3000, while you have the heat-sink removed, check the cut that was made on the 8T voltage line to pin 6 of J13 (see the K60XV installation instructions). If the cut was not complete it would interfere with the K2 power control as well as dragging the 8T voltage rail down. If your K2 is later than SN 3000, look for a solder blob making a bridge to the 8T voltage rail near J13 pin 6. 73, Don W3FPR __ 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

This corresponds to about 10 W output when using the K144XV. * COARSE TUNING WITH XVTR OFFSETS: Fixed problem with VFO display when using COARSE tuning steps in combination with a non-zero transverter frequency offset (CONFIG:XVn OFS). * IMPROVED FM RECEIVE: FM demodulation algorithm refined to reduce signal distortion. * FM SQUELCH: No longer opens briefly during memory recall. * ANT3 REMINDER WHEN K144XV SELECTED: If you switch to a band configured for use with the Elecraft K144XV internal 2-m module, “ANT3” is flashed to remind you to use the separate BNC antenna jack provided on the fan panel, rather than ANT1/2. Other new features and improvements: * NR (NOISE REDUCTION) ON/OFF: This is now saved on a per-band/per-receiver basis (same as NB). NR ADJ (noise reduction setting) is stored independently for each mode. * TX MESSAGE MEMORY ERASE: To completely erase a transmit message buffer, tap REC, then M1-M4, then CLR. Note that erasing a CW/DATA memory will not erase a DVR Message assigned to the same M1-M4 switch, and vice-versa. * ERR PTT ERR KEY (rig keyed at power-up): These error conditions no longer lock out the POWER switch. * DELAYED MEMORY RECALL (MV): In CONFIG:MEM 0-9, tap '1' to select MV NOR or MV DLY. NOR is the default, resulting in “live” memory recall as you rotate VFO A. In the DLY case, the receiver is not updated until you tap MV a second time to exit memory recall. You may prefer “DLY” if you have external gear that switches as the K3 changes bands. * 40-M TX RANGE EXTENDED TO 7.650 MHz (12 W MAX): TX near the first I.F. has always been disabled from 7.550 to 8.990 MHz to protect the 8.21 MHz trap on the KAT3 or KANT3 module. At power settings of 12 W or lower, the upper limit is now 7.650 MHz, allowing use of some additional MARS channels.

Re: [Elecraft] K3 and W2IHY EQ Plus!
I received the same reports as Lance (distorted or gravelly transmit audio) from local hams listening to my SSB signal when using the K3 noise gate feature, as compared with having it turned off. I simply opted not to use it any more, since I wasn't getting complaints about too much background noise anyway. What is interesting to me is that this noise gate audio problem even exists, given Elecraft's usually careful engineering practices. Since I know Lance is a 6-meter guy -- as I am -- I'm now wondering if the distortion experienced when using the noise gate maybe only exists on 6 meters. To be fair, I haven't tried using the noise gate in the most current release of firmware, so there's a possibility that this problem got fixed somewhere along the way. But I wanted to verify Lance's experience with it, FWIW. Bill W5WVO -- From: Lance Collister w...@q.com Sent: Monday, January 25, 2010 8:40 AM To: Gordan Hribar t93x_gor...@yahoo.com Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 and W2IHY EQ Plus! Hello Goran, I use the W2IHY Dual Band Noise Gate with my K3 and am very happy with it. If you only want to adjust the audio spectrum you can always use the built-in TX EQ in the K3. However, I have never bothered to adjust the equalizer inside the K3. My primary goal was to eliminate the high level of background noise from my VHF amplifiers when I operate SSB mode. Before I had my K3, I used a Heil HC5 element with the W2IHY, but now I use the Heil Proset K2 headset with my W2IHY and K3. My mic setting on the K3 is for the Rear Panel (where I have the W2IHY plugged in) with no bias. This K3 setting is also the same setting I must use if use the HC5 alone (however, I must change the setting to add bias if I use the Proset K2 directly). I set the K3 option for the TX GATE to OFF. Back in 2008, I was excited to learn that Elecraft was incorporating an internal noise gate into the K3, since I had hoped it would permit me to get rid of the external W2IHY unit. However, when I tried to use the internal TX GATE built into the K3, I would always get reports of distorted audio. Since I went back to the old reliable W2IHY Dual Band Noise Gate (over a year ago), I have only received excellent audio reports. I have not heard any comments from Elecraft regarding plans to develop a more effective internal noise gate. Therefore, if your interest is in using a noise gate to produce quiet TX audio, I highly recommend the W2IHY unit. GL and VY 73, Lance On 1/25/2010 8:37 AM, Gordan Hribar wrote: Hi all!

[Elecraft] K3 v 3.76 NR Release Notes
After loading v 3.76 the noise reduction setting reverted to F1-1, and this setting sounded good in the SSB mode. The only NR change stated in the firmware release notes was NR (Noise Reduction) ON/OFF. This refers to turning the NR on and off by band and mode. Nothing is said about any other tweeks. Were there other tweeks to NR? Thanks.

[Elecraft] K3: ATU but a bigger version
I really like the way that the K3 ATU works. It has that nice push my button and I will tune for you feel to it. But, it is so small. OK, kind of kidding here but it would be nice to have a big legal limit version of this tuner. Sure, a separate bigger box container. I don't really like some of the auto-tuners that I have seen that are in automatic mode and retune behind the scenes (so to say). I like to have some control over my auto-tuner. So, is there any hope that Elecraft might someday build a big 1500 watt capable ATU along the same style as the ATU in the K3? Knowing Elecraft, it would be highly configurable with firmware controlled features and options.
