Re: [Elecraft] OT National Hearing Test
Nope. I’m in the evil, ugly TV news business. I plead guilty to promoting things I find interesting and this was one — it is a hearing test based on ambient audio interference and sequences of three numbers progressively buried in the noise. Not unlike what we do everyday in amateur radio. Based own your answers, you get an average result. Mine: a little hearing loss on both ears. Slightly concerning because the XYL (or Gawd I used that term — surely lighting will strike!!) says I do not hear her all the time. Then again, I used an iPhone. I will try again with a dedicated land line. It is genuinely an interesting listening experiment.

[Elecraft] K3S + SteppIR Controller+ MacLoggerDX
If you’re running a K3 or K3S with a SteppIR controller and MacLogger DX, I’ve got a question for you: RS232 frequency data from my P3 is split with a Y-cable between the SteppIR controller and the Elecraft KUSB cable that runs to my Mac Mini. However, to allow MacLoggerDX to initialize with the K3S, I must briefly disconnect the SteppIR controller (MacLoggerDX finds the K3S no available), allow MacLoggerDX to initialize with the K3S, and then re-connect the SteppIR controller to the Y-splitter cable. Anyone have a work around? They do share frequency data very efficiently once initialized.

[Elecraft] Fwd: OT Mystery QRM Help (Video)
A bit more: I watched this mystery QRM pretty closely for an hour Friday evening as 20 meters closed for the day (by 6:30pm PST). The cadence of this noise changed. It slowed. Then faded away with the band. I’m scratching my brain to try think of a mechanical device that would create that kind of rhythm. And as always as I check 20 meters at 11am Saturday, there is no sign of the QRM. Will listen again late afternoon today. May experiment moving the DB-11 around to see if it is directional. > Begin forwarded message: > > From: David Ahrendts > Subject: OT Mystery QRM Help (Video) > Date: January 22, 2016 at 6:16:36 PM PST > To: "elecraft@mailman.qth.net" > > Stumped.

Re: [Elecraft] Filtering RFI from LED & flouresence Dimmer Switches
Thanks to all who have posted on this thread. Very informative. I have an entire house full of Lutron dimmers — all servicing halogens — circa 2001 design (pre-LED). And being a green guy with solar panels on the roof and plug-in hybrid, I was considering LEDs for the whole house. Will step very carefully now because of this discussion.

Re: [Elecraft] OT Apple Airport Extreme RFI
That did it. Many thanks, Steve. I took it a couple of steps further also. Got out a bunch of snap on ferrites and made a couple of one turn wraps on the AEX power cable. Further, I had intended on installing the MFJ 1164B AC Line RFI Filter (a 4-plug rugged RFI filter with a separate external ground), so I plugged it into a separate AC circuit and that combination made the AEX happy. 500 watts no problem. Like so many people, I have several Mac computers, two printers, an audio system, lamps, misc. gear all in proximity to the K3S and KPA500, and even though I do run a separate AC line for the ham gear, the non-ham gear is powered with a hodgepodge of power strips and extension cords. Clearly I need to get those in order also. So, case closed — happy to advise anyone who might have the same issue on my steps to resolve it.

Re: [Elecraft] OT 20M Moving QRM (Video)
Thanks, everyone, for weighing in. I’m armed with $95 of ferrite snap ons and chokes and two MFJ heavy duty AC filters! Saturday I plan to carefully re-design all of the AC wiring in my office/shack which is, admittedly, a hodgepodge of extension cords and power strips with at least 5 wall warts. I suspect the offending switching PS runs the brand new LG display used with the K3S SVGA. It’s a small, light little thing. Runs very hot. Most likely will be replacing it with a linear wall wart or something cleaner. I found this article that explains the differences between linear and switching power supplies: http://www.clever4hire.com/special-articles/home/ac-dc-power-supplies---using-wall-warts Will report back.

Re: [Elecraft] RFI resistant Monitor
Gerald, I’ve been on the RFI noise hunt for several weeks with my system. Added the SVGA with a very nice LG 23-inch LED monitor (M45 23M45D). Perfect size to fit above the K3S and P3. I’ve managed to lower my noise floor to typically well below S1, and do notice the LG producing a tiny high pitched noise from it’s switching power supply. I would use my 12V PowerWerx, but the LG switching PS produces something like 27 volts. I’m confident I can reduce the tiny noise some more.

Re: [Elecraft] RFI resistant Monitor
May I encourage everyone to study the excellent work from Jim Brown, K9YC — he weighed in here and you’ll see his link below. I’m also taking his suggestion after careful study to replace the parallel zip line red-black cable with shielded twisted pair cable (18 AWG ) with the Anderson Power Poles connectors. The theory being that anything twisted will resist RFI while parallel cable invites it and generates it. A fist full of ferrites helps also. Getting surgical, but it really helps.

Re: [Elecraft] New K3S
K3S #10125 was born Saturday, July 25th, 3pm. It’s companion PX3, yesterday. Still calibrating, but I just wanted to send five stars to everyone at Elecraft on yet again another wonderful experience in kit building. So much detailed thought goes into packaging, the assembly manual, and of course, the style and design. If you’re new to Elecraft and you’re exploring building a kit, just know you are expertly guided through the build process by thee best people in this business. I do admit I confused a 4.0mm spacer with a 4.8mm spacer, but that was in hour 7 of the build. I’ll forgive myself for that! :—) Five stars people. Bravo, bravo, bravo.

[Elecraft] K3S Power Up Audio Pop
Audio experts: I have a pair of AudioEngine 2 powered speakers servicing my beautiful new K3S (an excellent combo). On K3S power up and power down, there is pretty major audio surge pop that, I am sure, is not healthy long-term for the powered speakers. Can anyone suggest a small speaker connection modification to prevent or lessen that power up pop? It occurs to me the simplest thing to do is to power up the K3S and then power up the speakers.

[Elecraft] Multiple KUSB Connects

Re: [Elecraft] Multiple KUSB Connects
Yes, Phil, you’re probably right. Probably over-think here. But there are KAT500 parameters that can be more easily managed in real time with the KAT500 Utility, so I thought I’d give it a try. Dunno, in the bigger picture, might this be he precursor to the idea of software control or software monitoring of Elecraft devices? Maybe. My problem is when I connect five KUSBs they all have 10-or-12-digit names that I have to go through manually to find my device that I want to control (I know, I know, poor me!!!). AND they are power hogs. Mac OS X shuts ‘em down: too much power suck combined. So, you need a powered USB hub to connect a few. > On Aug 24, 2015, at 7:11 PM, Phil Wheeler wrote: > > Hmm ..

Re: [Elecraft] Multiple KUSB Connects
My friends, thank you for your many responses to this question. Clearly I’m not the only one thinking of multiple semi-permnanent KUSB connections to multiple Elecraft devices simultaneously. Lesson: all things are not equal when you select a USB powered hub. Among the responses that I found most valuable was this one sent directly from N1HO, Bayard R. “Brandy” Coolidge — much thought has been put into his USB to Mac setup — sharing it here with everyone: I just upgraded my shack from an Acer Netbook (1.66 GHz 32-bit, 2GB memory) to an early 2015 Macbook Pro Retina 13" at 2.7GHz with 16GB memory (and 250GB of SSD). I had used a powered USB hub from an "office superstore" that ran at USB 2.0 speeds, and had Sabrent USB/serial cables (which explicitly use FTDI chips) running to the K3 command port, the KPC 3+ (which went to another rig for VHF packet use), the Trimble Thunderbolt GPSDO's NMEA port, plus the SignaLink USB's cable. When I upgraded to the Mac, I also shucked the old USB hub in favor of a Sabrent 4-port USB3 hub. I'm running Windows 7 Home Premium under Parallels 10, and the Mac is running Yosemite with all the latest updates. (The Acer Netbook ran Windows 7 Starter). I've had this setup running for a couple of weeks now, and I'm extremely pleased. In fact, just yesterday I swapped out the SignaLink for an Asus Xonar U5 sound card, which Jim, K9YC recommended on the list - it works perfectly. Last night, I was able to take the rMBP, an old Alinco handheld, the KPC3+, the special cable to run from the Alinco to the KPC3+ and one of the USB cables with me to an ARES meeting. It all plugged in and played WITHOUT having to fuss with COM port designations, etc., etc. Came home, spent 5 minutes (maybe) reconnecting everything and all came up smiling. That said, I don't quite know what to tell you except that one thing that helped maintain some sanity with my old hardware configuration was to mark each and every cable and every USB hub port and never, ever plug them in "wrong". Otherwise, Windows would go off and assign a new COM port number to a given cable and I'd end up chasing my tail. I'm a retired UNIX software QC engineer, so my tolerance for that sort of baloney is minimal. One thing that bit me frequently, and took me months to finally nail down, was that for whatever reason, Windows would insist on spontaneously downloading, installing, and running a Ballpoint Pen device driver for the Thunderbolt, basically taking over for the mouse, resulting in all kinds of cursor movement and "clicks". I had to figure out how to outfox it, get into Device Manager and disable that driver. I later found a brief discussion on the Time-Nuts mailing list about it, and a few other guys had had the same problem and disabling under DM was apparently the only viable solution. (The Thunderbolt runs at 4800 baud). That said, I've been amazed that I was able to pull everything last night, go to the meeting with just the KPC3+ and then reassemble perfectly. Since you're going to be dealing with multiple K3s, and will probably want to run them both/all at 38400, you may go nuts trying to figure out which is which. Remember that the K3 Utility does display the serial number in the title bar, and you'll need to assign a different COM port for each rig, so I think some patient labelling and record keeping could help there. I rarely run the Utility anyway - only long enough to download and install firmware - so I don't (personally) see the need to run two copies simultaneously. However, you will need to figure out how/where to store the configuration files for each rig separately; I can't remember what the normal default file locations are offhand. But it should be possible to bring up the Utility and manually change its COM port so that it's talking to Rig B instead of Rig A. (Or there may be a configuration file for the Utility as well, so that it knows what COM port, etc. to use or it may be possible to invoke a specific COM port on the command line, in which case you could create two desktop shortcuts, one pointing to one rig's COM port, the other to the other - Lady Heather, the control program for the GPSDO does that, as do many other applications). BTW, under Parallels, you can force it to grab the various ports, including the external "sound card", away from OS X and assign them quasi-permanently to Windows, so that Windows will always be able to drive those devices. Again, I'm NOT a Windows expert, but I do hope that this provides some clues, and if you have further questions, please feel free to e-mail me, and I'll try to help. Very 73, Bayard R.

Re: [Elecraft] Multiple KUSB Connects
Interesting, Jack. K3S to KPA500 to KAT500 and a W2 to MA5B typically 1:1.2. Perfecto! Connected the just received KUSB-KPA500 cable to the amp and to a USB port on my Apple Thunderbolt 27.5 display running with the MacMini. Downloaded KAT500 Utility and checked to see I have current firmware. I did. Saved the config. Left the cable in place. Did a low power (amp in stand-by/amp in stand-by) 20M tune just to check if the KAT500 needed to adjust. Every red light lit up on the amp. Did not dare engage high power. No red lights on the KAT500 or the W2. Removed the KUSB cable and all was back to normal. Has to be RF traveling back through the new cable to the KPA500. Let me duplicate the situation again taking great care to separate the KUSB cable from any coax, and I’ll report back. David A., KC0XT > On Aug 26, 2015, at 2:46 PM, Jack Brindle wrote: > > I do.

Re: [Elecraft] Multiple KUSB Connects
Jack, reporting back, as promised: I could not replicate my red light experience tonight. Carefully keeping the KUSAB-KPA500 cable well away from any coax, I connected as I did yesterday to the Apple display and Mac Mini. Did a TEN WATT xmit (KPA500 in stand-by). All green lights. Same for 20 watts. Engaged OPER at 25 watts. Produced 500 watts from the KPA500. Smooth as silk. I clearly laid the KUSB right smack on top of the power out coax. No other explanation. So, case closed. And in the words of the very wise moderator of this list, Eric Swartz, (he’s thinking of this right now), “let’s close this discussion on Multiple USB Connects.” Thanks much.

[Elecraft] OT - High Power?
What do you regard as “high power?” Is our beloved KPA500 at 500 watts a high power device? Or do you have to have a big Alpha at legal limit?

[Elecraft] Elecraft Mac People: KUSB Issue
What can ya do to keep your fabulous Mac OS X device (in my case a Mac Mini) from kicking off the KUSB when it goes to sleep? Trying to keep MacLogger connected to the K3S via it’s KUSB for several days at a time (like Labor Day weekend). It appears to get kicked off for inactivity as a power drain which requires (I know, poor me!) re-starting the Mac Mini to re-initialize the USB port with the KUSB. Not a big thing, but maybe there is a way to refresh the USB devices connected (a Mac issue). Anyone?

Re: [Elecraft] Elecraft Mac People: KUSB Issue
Many thanks for the half-dozen direct responses off list. Most of you run a powered USB hub for the KUSB (or several). May I ask what type/brand powered hub are you successfully using with your Mac device for the KUSB or multiple KUSBs? It appears the chip in the KUSB can be interpreted as a real power hog, and the Mac Mini, MacBook Pro, iMac will protect against unusual drain. It just shuts off the USB port after a little warning. A powered hub would certainly remove that load from the Mac. I will also admit to being one of the million or so Mac beta testers and we’re currently on OS X El Capitan beta Version 10.11 (15A278b). And believe me, there have been/are plentiful Mac sleep-wake issues before they finalize.

Re: [Elecraft] K3S + FLDIGI + Mac Mini
Gentlemen, thanks. Answered my own question moments after posting. And I am in awe. With ONE USB cable on the K3S, you have rig control, audio in and audio out. Short answers: 1) In FLDIGI config, Hamlib, find your port and initialize it. That’s rig control. 2) In FLDIGI config, Audio, select PortAudio, USB Audio Codec for both Capture and Playback. 3) Select FLDIGI mode PKTUSB which moves the K3S to DATA mode. Otherwise it likes to default to USB. 4) On the K3S, MIC control becomes Line level and mine likes to be around 6 before tripping too much ALC. The P3 showing a clean PSK31 signal. Sweet. Now, my Mac Mini is a beta tester for Apple El Capitan, and version 10.11 Beta (15A278b) is a little buggy with FLDIGI. Many screen freezes which I’m sure will be ironed out in time. There was this cautionary issued on 9/11: http://www.machamradio.com/blog/2015/9/10-fldigi-and-upgrading-to-os-x-1011-el-capitan <http://www.machamradio.com/blog/2015/9/10-fldigi-and-upgrading-to-os-x-1011-el-capitan> Thanks, as always.

Re: [Elecraft] Final attempt at SOS !!!!
David, you’ve gotten some great advice here. In the last year I’ve built: KX3, KPA500, KXPA100, PX3, W2, KAT500, K3S and a P3. Best advice I can give is to make a place/space where you can separate all of the parts into understandable cups or trays, or something of your choice, and then label them. You’ll be dealing with lots of small screws and nuts and washers. Many look a like, but they’re not. I used my wife’s muffin trays — couple of them — and then you can quickly separate everything before you begin assembly to make sure when they call for a specific screw and a specific washer, you’ll know where they are in an instant. Know the Elecraft assembly manuals are very good. Really first class. They do ship a black-and-white manual, but I believe the download PDF is a color manual which does help in some rare instances. Best of luck with your K3S. Do not hesitate to reach out on this list or directly. Happy to assist.

Re: [Elecraft] KX3 + iMic Sound Card = Wild Scan
High fives to everyone who helped a dig-newby get up and running. Happy to say FLDigi is cookin’ on the Mac Mini using a SignaLink sound card and a home brew cable to the KX3-KXPA100. Thanks especially to Dave, G0WBX, who provided detailed help. Had my first PSK QSO LA to Alberta last evening. Love digital with the KX3.

Re: [Elecraft] sudden change in drivers for Griffin iMic used for PSK & RTTY
Julie, I can’t speak for the Windows side of this(I’m a Mac), but in my recent experience in coming up to speed with digital for the KX3, I too acquired an iMic, but ended up using my older SignaLink sound card with a modified home brew cable (which works wonderfully for FLDigi). The iMic’s were hard to find. Apple has discontinued selling them. Amazon was in “1 left” status. And Ebay was sparse.

Re: [Elecraft] Using external sound card for digital modes
My friend, I had the same type of problem in bringing the KX3 up to speed for digital. The rig would begin wildly scanning when connected to an Mic sound card. My solution was to use my old Signalink sound card instead with a home brew cable. Does a very nice job. In trouble shooting the iMic (which I never got to work), someone mentioned checking the mini-plug type. Remember the KX3 microphone plug is a tip-ring-sleeve plug (TRS). Presumably a mono or stereo plug would cause unexpected things to happen. My two cents for you.

Re: [Elecraft] Using external sound card for digital modes
Also, part of the magic of using FLDigi and a SignaLink card is that the software does all of the work by design. The KX3 remains in SSB mode for PSK or RTTY, so it becomes a quick cable swap to plug in digital or plug in a microphone. > On Jan 29, 2015, at 8:40 AM, David Ahrendts wrote: > > My friend, I had the same type of problem in bringing the KX3 up to speed for > digital.

Re: [Elecraft] Hot KXPA100 Amplifier
Would second all of this fine advice. I run the KX3 + PX3 + KAT100 into an Ameritron ALS-600S. And those clamp on chokes are essential. Using them liberally, and also making sure all the control mini-cables come no where close to the high-power coax outputs or the output from the KX3. Tidy things up nicely. Keeps the RF going where it should go.

Lynn, I have used and was very happy with the PAE-Kx33 https://proaudioeng.com/products/pae-kx33-ac-power-supply/ <https://proaudioeng.com/products/pae-kx33-ac-power-supply/> However, I acquired a few more Elecraft devices (PX3, KAT500, W2, and a relay for a larger amp), so I consolidated all of the 12VDC devices using a Power Werx 30 amp (more than enough) power supply http://www.powerwerx.com/power-supplies/ <http://www.powerwerx.com/power-supplies/> with Anderson Power Poles and the red/black zip line. Very neat. It was Elecraft’s recommendation to use a single amp rather than several smaller bricks. They use Power Werx in the field. Appears the single DC amp is the quietest and cleanest.

Re: [Elecraft] Ham enthusiast arrested
Super secret documents now reveal that Elecraft intends to skip the K4 and K5 and move straight to the K6. “Twice as big as the K3 with twice the knobs, and really big screws!” the design team said in a draft announcement scheduled for release in a drought-stricken central California town on April 18th. “Huge…really huge,” one observer with inside knowledge said while emphasizing the K6 will be water-cooled and peddle self-powered with enough reserve to power several other devices simultaneously including an optional ham-equipped self-driving autonomous Tesla specially designed with Levitation Mode for those occasions when you just need a 500 foot legal limit perch to break through that pile-up with Asiatic Russia.

Re: [Elecraft] KX3 And SignaLink USB
Hey Dale, I’m successfully using FLDigi on a Mac Mini, the SignaLink USB device and the KX3/PX3. Use the RED TRS (tip, ring, sleeve) mini-plug (or any similarly wired cable) and plug one end (the straight plug is my preference) into the SPKR output of the SignaLink device, and the other end (right angle mini-plug) into EARPHONE plug on the KX3 — this is receive line. For the transmit line, you may have to home build, but it is easy as pie. In my case, I have an RJ-76 out of the SignaLink device into an adapter that connects to a right angle TRS mini-plug which plugs into the KX3 MIC plug — this is the transmit line. I prefer using the SignaLink device because it does a wonderful job of isolating the KX3 from the Mac Mini (I think that’s important), and it regulates input and output levels really well. I do place a cheap external speaker on the SignaLink box, AUX output, so I can simply hear the digi-data back and forth in the background at a really low level. Happy to provide any guidance off list including photos, etc. The home brew transmit cable cost six-bucks, a modified MIC cable.

[Elecraft] AFX MD Delay
Wayne and Eric, this is fabulous audio design and I really love it on my KX3 and, I’m sure, on my yet-to-be-shipped/built K3S. It appears to be more than just a delay/reverb effect. Am I hearing just a delay left-to-right? Quasi-stereo? Or…? In any case, it is quite effective. Feels three-dimensional. Not flat. Very nice. Especially with phones.

Re: [Elecraft] KX3 - KPA100 communication problem
A fine issue this is, Bernie. Couple of questions: 1) Tell us about the connection to your computer. What type? How are using the computer with the KX3/KPA100/PX3? 2) Have you checked the software settings for the KX3 Utility, the KPA100 Utility and the KX3 Utility? All good there? 3) And just for the heck of it, have you tried swapping KUSB cables in the event one of those may be the culprit? Just my two cents.

Re: [Elecraft] Microphone Qusestion
Bob, you’ll get a hundred suggestions on this list, but the Heil PR781 is a superb choice. Or the Heil Gold Elite. I use the PR781 with the W2IHY EQPlus and 8-band EQ and the combo of the already top notch mich and EQ are superb. Additionally, pushing that fidelity into Elecraft’s ESSB (up to 4kHz) produces an extraordinary result. Best wishes. Happy to demo for you — contact me off list and we can set up a 20M QSO.

[Elecraft] KX3 and the Heil Gold Elite Michrophone
Friends, you are an incredible group of amateur radio enthusiasts, and I am so looking forward my KX3 kit and it’s companion KXPA100 arriving next week. I’m transitioning from the Kenwood TS-480HX (no complaints about it at all) where I use Bob Heil’s Gold Elite michrophone (little bit of a base boost to really impress people, and a switch that allows you to narrow up the audio to push through pile-ups). Heil does not have a KX3 cable or an adapter for the Gold Elite. Does anyone use a Heil microphone with the KX3? Many thanks. This list, BTW, convinced me to get on board.

[Elecraft] KX3 + KXPA100 and ACC1
KX3 serial 6-thousand something is born. Very impressed. What a tight little machine. Maiden QSO last evening using the KXPA100 @ 110 watts. This is a very efficient combo: under 5 watts easily excites the KXPA100 to it’s max. Here’s my question: the KXPA100 cable takes up the ACC1 and ACC2 slots. I would really like to use one of the software spectrum displays (maybe iSDR for the iPad, or a Mac equivalent). However, they require ACC1 out. Can ACC1 be split somehow for two devices?

Re: [Elecraft] KX3 + KXPA100 and ACC1
Indeed it is! Thanks for answering a newby. Now, another question for all of you: is there any complication that typically develops when running the 100 watt KXPA100 into a higher power liner amplifier. In my case, an Ameritron ALS-600S. I am aware of the switching cable phono plug on the KXPA100 that has to connect to the Ameritron external on-off relay. > On Oct 23, 2014, at 10:05 AM, Matt VK2RQ wrote: > > The ACC1 port is split out on the KXPA100 itself -- plug your PC into the > "PC" side ACC1 port on the KXPA100, and the KXPA100 will forward any KX3 > commands to the KX3 (ie. it is basically a "daisy chain" connection topology) > > 73, > Matt VK2RQ > >> On 24 Oct 2014, at 3:38 am, David Ahrendts > <mailto:davidahren...@me.com>> wrote: >> >> KX3 serial 6-thousand something is born.

[Elecraft] KX3 & KXPA100 into Ameritron ALS-600S
I want to run my just-born KX3 and it’s 100-watt companion KCPA100 into a high power linear, my Ameritron ALS-600S. But we have some issues. For instance: the combo easily produces 600 watts CW. But, on SSB it far too easily trips the Ameritron load fault, or the KXPA100 high SWR shut down. This rather acts like RF feedback. Maybe I just need to follow better RF hygiene here (higher quality coax cables, making sure RF does not loop back on a power cable, etc.). Any collective wisdom appreciated.

Re: [Elecraft] KX3 Questions
Larry, I assembled a KX3 and it’s companion KXPA100 amp 3 weeks ago, and it is an outstanding combo. I’m replacing a Kenwood TS-480HX (an outstanding device also) which I ran with an Ameritron ALS-600S 600-watt linear. With some balancing and shielding I will be able to run the KX3 + KXPA100 into the 600 watt linear. So, I have my super compact QRP radio that I can put in my back pack and sit on a lawn chair with a Buddy Pole on top of a mountain, or the high power base station on my desk at home with the mini-beam. Cake and eat it too. The KXP3 pan adapter for the KX3 arrives today — my weekend project. I’ll suggest the roofing filter especially for CW. Did not get an antenna tuner for either the KX3 or KXPA100, but might reconsider that later, since I have an auto-tuner for the big linear. Had no interest in using the KX3 on 2M and actually for the cost, you could probably find a very nice 2M rig. Assembly suggestion: they provide you with a lot of little teeny tiny screws. Get a cupcake pan or ice cube tray and separate all the parts and label them. Very difficult to tell a 5/32 screw from a 1/4. Tweezers help. And the customer support is extraordinary.

Re: [Elecraft] KX3 Audio Compressor
Thanks, Gary. I will study up on this. With my really hip (and very effective) headphones, the difference is quite pronounced. I too have always gotten “great audio” comments using the Heil with my about-to-be-sold TS-480HX and TS-480SAT, and I would run pretty full on compression in as full a fidelity as the unit would produce. It was often described as “punchy” and would always push through a pile-up. I fully get the idea that in major contesting, fidelity is not the concern — you wanna be heard. But can’t ya have it both ways without sounding “thin” and “tin-ee.” David A., KC0XT > On Nov 11, 2014, at 8:40 AM, Gary - NC3Z wrote: > > This has actually been a topic of several discussions on the KX3 Yahoo group. > If you look at the KX3 on a spectrum analyzer you will see that when the > compressor is turned on that the TX BW goes from about 2.8KHz to 2.4KHz.

Re: [Elecraft] KX3 Audio Compressor
Wayne, I am loving the KX3, KXPA100 combo and have it now balanced and operating virtually 100% into an Ameritron ALS-600S. And the Dr. Dre’s, I am cooking! :—) On the audio thread, I also noticed a huge audio difference between the Heil Gold Elite and the Elecraft MH-3. While the Heil was a producing a beefy, rich audio presence, the MH-3 was present but quite thin by comparison. I know these are subjective comparisons and there is no doubt the audio shaping has been successful for lots of people, I’m just compelled to raise the bar a little bit on audio shaping. Just my preference for routine contacts. Love the rig.

Experimented yesterday for a few minutes with ESSB (carefully avoiding weekend contesters), and it raised a fundamental question: As bandwidth is broadened, is effective radiated power diluted? In other words, will 500 watts with a 2.6MHz signal be more effective (stronger, punchier, more DBs transmitted) than 500 watts with a 4MHz ESSB signal?

Yes, KHz, of course. Didn’t have the courage to consume 4KHz :—) but I did answer the Elecraft net call at 1800z at 3KHz. > On Nov 17, 2014, at 10:29 AM, Phil Wheeler wrote: > > I think you meant KHz, not MHz, David :-) > > My thinking is that the narrower "communications quality" signal would be > more effective. > > How did you find 4KHz with none of those contesters on it?

Well put, Al. Thank you. More watts per Hertz! > On Nov 17, 2014, at 10:48 AM, Al Lorona wrote: > > Your intuition is correct, David.
