[Elecraft] Re： K3: USB port - give the guy a BREAK!
Hello Doug, I concur with you and it is no harm to voice out our wishes here. In fact, what Elecraft promoting is 'respond to customer's needs', this is the reason why we regularly have beta version firmware. In our K3 or K2, we have paid for good support service and response from Elecraft direct. Everyone in this reflector says that and Icom / Yaesu / kenwood cannot do that. I also would like to have USB port if it were practical to do so. Of course, i won't pay US$100 for that option. cheers, Johnny VR2XMC - 郵件原件 寄件人﹕ DOUGLAS ZWIEBEL doug...@gmail.com 收件人﹕ Elecraft Reflector elecraft@mailman.qth.net 傳送日期﹕ 2010/11/19 (五) 5:56:45 PM 主題： [Elecraft] K3: USB port - give the guy a BREAK!

Re: [Elecraft] K3: USB port - and SteppIR antennas
Who really needs a USB port on the K3? The converter works perfectly well... Yes, it may be possible to replace the K3IO board with one having a USB port. BUT: What are those of us using SteppIR antennas which track the K3's VFO supposed to do? The SteppIR requires an RS232. Or shall we ask SteppIR to implement a USB port in their control unit as well? Would that be worth it? IMHO, it wouldn't. I'm quite happy with the serial port and converter. 73 Richard - HB9ANM - Richard - HB9ANM -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-USB-port-give-the-guy-a-BREAK-tp5754717p5755076.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

Re: [Elecraft] K3: USB port
I can understand why a lot of old timers want to stay with serial port for the K3. Many people just don't like change. The simple fact is the world has moved on Something like 15 years ago. USB is the standard and a product like the K3 which In many ways is cutting edge should move on also. When was the last time you saw a new computer with serial port or a floppy drive? It can't be that hard to change to USB. There are plenty of $10 items that support it So it must be cheep. I figure it is a lack of will on Elecraft's part.

However, that does not get you audio ... To do audio, you would need not only the USB converter but a hub and USB Audio CODEC (e.g. PCM8902 or similar). Then Elecraft would need to build controls for the USB CODEC (ADC/DAC) and do all the other software support - further burdening the K3 CPU. After all that, all you've done is move the USB soundcard, USB to serial converter and USB hub into the K3 and added a whole new level so support burden - providing operating system specific drivers for each version of Windows (along with the cost of signing drivers with Microsoft), specific drivers for each version of OS-X, and specific drivers for each unique version of LINUX. By the way ... depending on the USB Audio chip set (ADC/DAC) and USB hub, you might find yourself needing specific drivers for each chip (Audio, hub, control) *and* EEPROM to customize, control and serialize each of those chip! After all of that you have not provided any new capability for the K3. Other than adding at least $100 per unit in hardware, development, and ongoing support costs the only thing this exercise will accomplish is to relieve a relatively small number of users of the need to purchase a KUSB and allow them to keep their sound- card free for iTUNES. For all the rest, you have increased the cost of the K3, added an entirely new level of complexity to the rig, and perhaps required that the user purchase new hardware to use their rig with computer control. 73, ...

Re: [Elecraft] Yamaha CM500
All: I have the Koss headset that Joe W4TV illustrates from New Egg. It cost me $23 last year from Full Compass (Yet another headset? But it was on Sale! I couldn't resist!). Mine is labeled SB-40. Its absolutely and EXACTLY IDENTICAL to my CM-500, in every detail, except for one important thing. The mic capsule. The mic capsule on this headset is dynamic and is absolute and pure junk. However. A Heil capsule and holder from the BM series of headsets fits PERFECTLY on the end of this headset's flexible boom. I have several old BM-5 and BM-10 headsets in my junk box. I love them. Light and comfortable, you can forget you're wearing a headset. But they are notorious for breaking the little plastic clip that holds the metal boom on the headset, and the open air design, while extremely comfortable, doesn't lend itself to noisy SSB multi op environments... So in search of a solution, I took a close look at the Koss headset and found that its a simple matter to remove two screws from the mic holder on the end of the boom and it comes right off, leaving the capsule dangling on two wires! Unsolder the Koss mic capsule. Place it right in the garbage can... Unscrew the pop screen, unsolder the capsule and then remove the capsule holder from the metal tube boom of an old Heil BM-5/10 headset by gently twisting it off of the tube. With a Dremmel tool, widen the BM-5/10 mic holder's boom hole a little bit so it fits snugly on the Koss boom (add some epoxy if you feel safer with gluing it on, I don't, what if it cracks?). Then, slide a 1/2 inch of shrink tube on to the Koss boom and install the Heil holder, thread the wires through, and heat the shrink tube to hold the Heil capsule holder onto the flexible boom (and make it replaceable by cutting the shrink tube off with a xacto knife if you need to later). Finally, solder your choice of Heil capsule (in my case, a DX-4) onto the wires. Replace the pop filter by screwing it back on. PRESTO!

The reason we went with RS232 initially is that many hams are still using PCs that have only RS232 ports. Those who prefer to use USB can use an inexpensive USB-to-RS232 adapter. There is no difference in I/O performance between the two methods. Just wanted to revisit this topic and find out if anyone has heard anything more regarding a possible USB interface for the K3. I know it's not for everyone, but for myself and perhaps others out there, the ability to carry all data, including audio on a single cable would be convenient. Right now, I'm using a Keyspan USB to RS232 adapter for data, along with two separate stereo cables for audio. I don't have any real complaints with that setup, but could be problematic when transferring the rig around from computer to computer. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net 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 -- 73 de James K2QI President UNARC/4U1UN __ 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] P3 Wow!
My new P3 arrived yesterday, and I like it a lot! It's very easy and intuitive to operate. As someone who spent part of his career doing spectrum analysis (of sound and vibration), I don't know why I waited so long to acquire this fine accessory for my K3. I still need to do the IF output modification on my K3 for full sensitivity in the P3 display, but am still finding the visual display useful for combing through DX pileups. 73, Chuck NI0C K3 s/n 1061, P3 s/n 444 __ 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 Wide AGC threshold
As a new K3 owner, it is entirely possible I am treading ground already well trodden. My apologies should this be so. While waiting for delivery of an Inrad 500Hz roofing filter, I have been accumulating experience with S/N 4904. I am enjoying my new rig greatly, although I confess to finding an odd thing or two puzzling. One of these relates to the level at which wide AGC has been set. My primary shack transceiver is a home built, G3XJP designed Picastar, which has a similar architecture to the K3 but is based upon the much older Analog Devices ADSP2181 and AD1885 AC'97 codec. Unlike the K3 with its multiple choice roofing filter bandwidths, my Picastar uses a single 4kHz wide roofer in all modes. The thing puzzling me is that I find de-sensing by strong signals within roofer b/w but outside DSP b/w far more noticeable on the K3 than on Picastar. I expected the opposite to be true given the Picastar codec has only a 16 bit ADC whereas the K3 has 24 bit. A quick measurement reveals K3 wide AGC threshold around 70dB above MDS whereas on Picastar it is closer to 80dB. With Star's 16 bit ADC this equates to around 10dB headroom whereas the K3's 24 bit ADC implies headroom in excess of 30dB. On the face of things it would appear some 20dB of extra defence against strong signals in the no man's land between roofer b/w and dsp b/w has been sacrificed. I am wondering why? Perhaps I am missing something? Thanks.

Re: [Elecraft] K3 Wide AGC threshold
That's not the wide AGC. It's the defensive hardware AGC that is in the actual IF string after the roofing filter before the analog to digital converter (ADC). It's function is to limit the level presented to the ADC as you surmise. It is also primitive, easily seen in the schematics. Handling strong signals without any AGC pumping, using an SSB roofer ahead of a CW DSP bandwidth, I doubt was a design goal of the RX. What you experience is common for those without a CW roofer. There was some variation in how the K3 handled this which was up in beta firmware very early on, and various settings were evaluated by the community. I'm sure you can find the blow-by-blow back in the archives. 73, Guy.

Re: [Elecraft] K3: USB port
Hi Rick, I would suggest the Keyspan USB to Serial adapter over the KUSB. With the KUSB, I always had problems with it when using programs like HRD or DM780. I believe that was due to the drivers being used. OTOH, the Keyspan unit works very well and does not seem to add any additional noise into the equation. It also seems to be well shielded from stray RF. 73, James K2QI On Fri, Nov 19, 2010 at 11:26 AM, Rick Prather k6limae...@gmail.com wrote: Sorry James but sometimes sitting in pile up that is out of control brings out the worst in us!

Guy Thank you for putting me straight on the terminology. Perhaps I can rephrase my question. The hardware AGC appears to be set at a level which precludes effective utilisation of the 100dB+ DR of the DSP system.

Handling strong signals without any AGC pumping, using an SSB roofer ahead of a CW DSP bandwidth, I doubt was a design goal of the RX. What you experience is common for those without a CW roofer. There was some variation in how the K3 handled this which was up in beta firmware very early on, and various settings were evaluated by the community. I'm sure you can find the blow-by-blow back in the archives. 73, Guy.

While waiting for delivery of an Inrad 500Hz roofing filter, I have been accumulating experience with S/N 4904. I am enjoying my new rig greatly, although I confess to finding an odd thing or two puzzling. One of these relates to the level at which wide AGC has been set. My primary shack transceiver is a home built, G3XJP designed Picastar, which has a similar architecture to the K3 but is based upon the much older Analog Devices ADSP2181 and AD1885 AC'97 codec. Unlike the K3 with its multiple choice roofing filter bandwidths, my Picastar uses a single 4kHz wide roofer in all modes. The thing puzzling me is that I find de-sensing by strong signals within roofer b/w but outside DSP b/w far more noticeable on the K3 than on Picastar. I expected the opposite to be true given the Picastar codec has only a 16 bit ADC whereas the K3 has 24 bit. A quick measurement reveals K3 wide AGC threshold around 70dB above MDS whereas on Picastar it is closer to 80dB. With Star's 16 bit ADC this equates to around 10dB headroom whereas the K3's 24 bit ADC implies headroom in excess of 30dB. On the face of things it would appear some 20dB of extra defence against strong signals in the no man's land between roofer b/w and dsp b/w has been sacrificed. I am wondering why? Perhaps I am missing something? Thanks.

[Elecraft] P3 behavior with REV-button in use
I am searching the SPLIT pileup by pressing the REV-button and listening to the up frequency range by turning the same time the big VFO knob to find the listening QRG of the DX station. Unfortunately the P3 behaves the following way: 1. Center frequency display does not change but spectrum display jumps to the split QRG. I do not like the jump in the spectrum. 2. The VFO B cursor does not change. After releasing the REV-button I have to turn the VFO B knob slightly to see the right position of the VFO B cursor.

Re: [Elecraft] K3: USB port
Since the day it first powered on, my K3, #3192, has featured full USB radio CAT/keyer support with dual channel embedded audio I/O. All I need to do is plug a single USB cable in to any computer for all of this functionality with any popular logger/rig control software. Totally painless and plug and play on any recent MS OS, from Win2k to Win 7, on laptops, desktops and even netbooks (I've tried them all). What is it? Its called The microHAM microKEYER 2 :) Paperclip reliable, no RF pickup, works with Dynamic or Electret mics, dual receive compatible for dual RX RTTY, keys CW, RTTY, PSK, HellScrhiber, THROB, Stream, (in fact, every digital soundcard mode I have ever tried), built-in DVK, and CW memories, Two Tone test signals and features a setup/management GUI you can use to customize it. Dont want to use the computer? Its also a self contained keyer with a built in WinKey chip. It also can display your other VFO/KRX3 frequency in its LCD display when the display on the K3 is being used for other things, like RIT or CW Decode. And it impersonates a Icom rig, allowing you to directly interface to things that use the CI-V bus natively; helpful in my all Icom club environment when I bring in my K3 to use the microHAM antenna switching system... everything works just like the 7700 or Pro2's were connected to the Station Masters without any reprogramming! Just plug the CI-V cable in and go! Folks, you've just spent over 3 grand on a high performance radio...

After all that, all you've done is move the USB soundcard, USB to serial converter and USB hub into the K3 and added a whole new level so support burden - providing operating system specific drivers for each version of Windows (along with the cost of signing drivers with Microsoft), specific drivers for each version of OS-X, and specific drivers for each unique version of LINUX.

The reason we went with RS232 initially is that many hams are still using PCs that have only RS232 ports. Those who prefer to use USB can use an inexpensive USB-to-RS232 adapter. There is no difference in I/O performance between the two methods. Just wanted to revisit this topic and find out if anyone has heard anything more regarding a possible USB interface for the K3. I know it's not for everyone, but for myself and perhaps others out there, the ability to carry all data, including audio on a single cable would be convenient. Right now, I'm using a Keyspan USB to RS232 adapter for data, along with two separate stereo cables for audio. I don't have any real complaints with that setup, but could be problematic when transferring the rig around from computer to computer.

[Elecraft] OT: QST's review of the Yaesu FTDX5000MP
Hello Nate, In relation to your comments about IC7600, I would add the following: 1. There is 'manual notch within AGC loop' in IC7600. This function is very useful when I use it to notch out a strong offending carrier right adjoining to my wanted desired weak signal. Since the notch is within AGC loop, the wanted weak DX signal will pop out right from the noise ground after the carrier is notched. The desense of AGC by the strong carrier disappears at the same time. I did an A/B comparison of the above during the recent CQ WW SSB contest. 2. When we calculate the cost for comparison, we have to add P3 to K3 to bring it in line. Bearing in mind, IC7600 only costs US$3,250 in Hong Kong I am still running my K3 but just plainly spell out the fact as above. cheers, Johnny VR2XMC www.qrz.com/callsign/vr2xmc - 郵件原件 寄件人﹕ Nate Bargmann n...@n0nb.us 收件人﹕ elecraft@mailman.qth.net 傳送日期﹕ 2010/11/16 (二) 8:14:42 PM 主題： Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP * On 2010 15 Nov 21:49 -0600, Luis V.

That's not say that some of their later products weren't good, just that they had lost their edge, especially to Yaesu in the early '90s. And Larry, you're right, from a technical perspective, the 590 receiver schema is really Goofy! It strikes me as rather odd as well. I suppose that the Kenwood engineers and management have their reasons, but wow! When I read preliminary information on it, I came to the conclusion that it was more complicated than it needed to be. Elecraft's well targeted market niche is being attacked from above by the FTdx5k and from below by the 590 and to a lesser extent, the Eagle. Most of the erosion will be in the lower side of the equation. Main K3 competitor is really the IC7600, and technically it leaves a lot to be desired and is not as customizable, but undercuts K3 in price and it has the Icom mystique by association. Icom has done a masterful job at brand identity. And here I thought ICOM stood for I Can Only Monitor! ;-) To be fair, I've only owned two Icom transceivers over the years, an IC-290A 2m all mode that was the first commercial rig I bought in 1985 and later a 4AT HT. Both served their purposes well. Early on I would fall into the Kenwood camp for HF gear and later Yaesu for all my gear. In fact, I was all Yaesu until I received the K3 last month. I liked the idea of performance that rivaled the big boxes in a size near that of my FT-890AT. Watching this list and seeing Elecraft's interaction with its customers won me over. So the K3 niche is still rather exclusive, but eroding a little bit. I'll agree the K3 is niche, but I'm not sure it's saleas are eroding. Of course I don't have sales figures, but it would appear that at least 100 more have sold since I got mine on the air about a month ago which seems healthy for a niche product that is positioned toward the high end of a niche hobby. Considering as well that the overall economy is not doing as well as when the K3 was introduced, I'd say it's doing quite well. I'd also submit that as mentioned earlier in this thread that there are those who would not be comfortable buying a K3 for their main transceiver as they feel more comfortable going with a product from one of the brand names. I can understand that as it took me a while to accept the idea as I spent several months evaluating Elecraft as a company before I took the plunge. The established players are known quantities while Elecraft is still building its reputation in the larger amateur radio community. I'm a bit of a risk taker on things like this so I suspect I'll receive some questions about the K3 at tonight's club meeting. Elecraft is a lot like Honda in the mid 70's. Pick the niche, build a solid product and back it with uncompromising service, winning one customer at a time. I take for granted you're referring to Honda cars. In motorcycles, they were a juggernaut at the time. Which allowed them to bring products like the CBX to market.

Re: [Elecraft] K3: USB port - and SteppIR antennas
HI The USB/Cable adapter + RS232 is, at least, a solution which ensures a perfect compatibility for the future of any operating system. Unfortunatly an USB port is dependant on the willingness of the manufacturer of the chip. Not an RS232 port that you can use on any system. To understand, I suggest you try an ICOM IC-1500 (which features only an USB port) under W7/64 bits!... But you are right right : RS232 ports are obsolete; but if an USB port is a good solution for a cheap webcam, it is not a solution for long life equipement like transceivers since it is compatible with a limited number of systems. In my humble opinion, the way to go is a TCP/IP port with all parameters accessible from any browser on any system... and with a bonus... remotely (like a cable/dsl modem). It is strange that none of the current manufacturers develop such system (except TenTec with the OmniVII but with limited capabilities since it does not include a web server). Logging control should not be a problem with a TCP/IP server. 73, Laurent F6DEX - Laurent F6DEX -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-USB-port-give-the-guy-a-BREAK-tp5754717p5756656.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

Re: [Elecraft] K3: USB port
I would like to think that as hams we were technologically savvy enough not to just want change for change's sake. Unless you have a laptop for the shack PC (in which case the question why? springs to mind) there is no problem with using RS232. I have a 4 port serial card in my shack PC and all of them are used. This leaves my USB ports free for things they really are needed for, such as 3 external USB sound cards (yes I have 4 radios connected up to my shack PC - try doing that with a laptop. And yes, I am an old timer.) Having an RS232 port does not deny those who want to use USB from doing so. It just means the cable you use isn't a passive cable but has a bulge at one end with the USB interface chips in it. RS232 also gives you the option of using nice one USB cable interface options like the MicroHam products if that better meets your needs. It's about giving people choices about how they interface their radios instead of assuming that they just want to connect it to a PC. What is so bad about that? Dan Copeland wrote: I can understand why a lot of old timers want to stay with serial port for the K3. Many people just don't like change.

Re: [Elecraft] K3: USB port
I have another solution (sort of tongue-in-cheek) for those who want the USB directly on the K3 rather than converting it to serial out of the computer. Attach the serial end of the USB to serial adapter permanently into the K3 RS-232 connector, and if you need more cable to make the run to the computer, just use a USB extension cable. On a more practical side, it permits use of the SteppIR Y cable, or any other device that is similarly designed to listen in on the RS-232 communication, I think that is a solution to answer all needs - many K3 owners also run the SteppIR, and I hope they are not among those who clamor for native USB support in the K3. Those who want to use USB can then connect between the computer and the K3 (via the captive adapter) with a USB cable, and those who are more inclined to not mind running an RS-232 cable can do so easily by connecting their USB to serial adapter directly to the computer. I think this is more in the choice of cable than it is an RS-232/USB question - Yes, if the K3 has a native USB port it brings along all its problems - see the W4TV post. RS-232 is not device dependent, USB IS device dependent, and that is the real difference. I see the problem as a computer problem (no RS-232 ports), and NOT a K3 problem (there are good adapters available). When the Universal Serial Bus becomes actually universal, and not device dependent, I will likely change my mind, but right now, the only really Universal Serial Bus is the RS-232 serial port. Your definition of Universal may vary from mine. Until the support code for generating RS-232 signals disappears from operating systems, I will continue to use them - I think desktops are more suitable for the hamshack computer than a laptop - they are less expensive and more reliable -as an example of one with 2 serial ports, see the IBM ThinkCentre M52 9210 Desktop Computer for $179.95 at Tigerdirect.com, Add a monitor for $100 and you have a dedicated hamshack computer with real serial ports. 73, Don W3FPR On 11/19/2010 2:20 PM, Lu Romero wrote: Since the day it first powered on, my K3, #3192, has featured full USB radio CAT/keyer support with dual channel embedded audio I/O.

Re: [Elecraft] Fwd: K3 Wide AGC threshold
There was some writeup I seem to remember that there were some conditions where the lower threshold worked better. If one does NOT PREFER using wide bandwidth to tune CW, the current stock setting IS better for some reason that I can't give you. My CW contesting use makes wide filters simply useless for CW. There is ALWAYS a 35 over S9 signal up 350 Hz from me, no doubt due to some natural law related to entropy. To get him out of my bandpass and copy the calling S minus 3 QRP basement noodle antenna station that accidentally disconnected his noodle and doesn't need it yet, I need BOTH the DSP and the narrow filter. Your current filter situation would be simply hopeless. You will love it when you finally get it. 73, Guy.

Hi Bob...spoken like a former Orion user! You're absolutely correct...but it's actually much better than it was originally. Why? I have no clue. 73, Bill Hardware AGC threshold change (HAGC Mod Kit) http://www.elecraft.com/K3/k3_app_notes.htm (scroll nearly to the bottom) SMD HAGCMDKT instructions Both through hole and SMD parts are included. Users can install either set of parts. Some users prefer tuning the band with a wide filter bandwidth selected (for example, using a 2.7 or 2.8 kHz SSB filter in CW mode rather than a 500 Hz or narrower filter). Strong off-frequency signals (above about S9+5) that are inside the crystal filter passband can then activate the hardware AGC circuit, reducing the level of desired signals. This modification raises the hardware AGC threshold from about S9+5 to about S9+25 to +30. The new threshold still protects the DSP's analog-to-digital converter, while providing better receive performance when wider crystal filters are used. This is not as significant an issue when using narrow CW filters (500 Hz and below). -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Wide-AGC-threshold-tp5755595p5756731.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 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
Well, as a recent convert (September), I agree you made a fine choice. I ran Icom IC-765's for the last 20 years (all cw) and, while I still think the 765 is one of the finest cw radios ever made, the filtering of the K3, and the excellent sub-receiver, are a significant step up. I wrung it out in cw Sweepstakes and it performed up to expectations. I don't know what you had before, but you'll love the K3 performance (which is, as you no doubt grokked from this site, a moving target ;-) and you'll be constantly challenged by the near-infinite collection of features buried in the menus.

No, you probably don't realize that Spectrogram uses the default audio input device and that Windows systems commonly default to the computer's built-in microphone. You are probably getting nothing more than acoustic coupling between the K3 speaker and the computer's mic. This assumes that you have not intentionally configured the K3 and computer to use a cable between the K3 Line Out jack and the computer's Line In jack and made that the default.

I have just received a new Kenwood MC 60A desk microphone and I need some help setting it up.I am using it with the K3. I understand that two of the pins are different for the power to the preamp. How necessary is the preamp and should one change the plug from pin 5 to 6 on the mic? If one does not will using the batteries enable the preamp? What settings have users found good in terms of gain and compression on the k3 and eq settings with and without the preamp for the MC60A? I found that without installing the batteries while listening through headphones in the test mode turning on the switch to the preamp seemed to boost the audio. I do not understand what is happening without changing the wiring on the mic and not installing the batteries. Also, is it best to use the high or low gain setting on the k3. and which setting are best with or without the preamp. I have the bias off on the K3 and the impedance set to low on the MC60A.

Re: [Elecraft] kenwood MC-60A
Eric, Go to http://homepage.ntlworld.com/rg4wpw/mc60a.html. G4WPW has done a great job of documenting many, many microphone pinouts and transceiver pinouts. What I observe with the Kenwood MC-60A is that pin 6 is unused, so it should not be a difficult task to change the mic plug - just move the wire from pin 5 to pin 6 and you have it wired for the Elecraft pinout. The schematic did not show a provision for batteries, but if it does not include a disconnect for mic plug pin 5 when the batteries are used, it may cause problems for the K3 - just guessing based on a lack of proper information. The best way to set up the gain for any mic is to do it as instructed in the Elecraft K3 manual rather than just copying someone else's settings; You can use TX TEST. Turn the compression to zero Watch the K3 ALC meter while speaking into the mic and adjusting the mic gain. When you have 5 to 7 bars illuminated that is the correct setting. If the range is high, and the mic gain number is low, try the low setting to obtain a less touchy adjustment range. Once set, just leave it that and forget it for that mic. After setting the mic level, bring up the compression to whatever level you want - 10 dB is normally suggested for general use. Try the above setup steps for all the different settings on your microphone, and select the one that works/sounds the best. 73, Don W3FPR On 11/19/2010 8:28 PM, Eric Lanzl wrote: I have just received a new Kenwood MC 60A desk microphone and I need some help setting it up.I am using it with the K3.

Use the high gain setting (fP.H) on the K3 and don't bother with the preamp. If you do that you don't need to worry about rewiring the mic plug. 73, ...

Re: [Elecraft] Yamaha CM500
No problem, Jim: Its not that I cant make the Electret CM-500 work on the Orions at NQ4I (I have the bias box), its just that the mic sounds really bad on that rig, no matter what I try to do with the rig's EQ, or what little EQ capability is in the rig (They are Orion 1's). These Orions are really bassy. I have diddled with the carrier shift and transmit bandpass and have gotten the rigs to sound pretty good, but there is still a lot of difference between the radios (there are 8 of them), even with the same exact settings. I have been volunteered as the audio guy up there. Of all the mics we have tried (and we have tried a lot of them), These Orion 1's seems to really like the DX4 capsule. Recently, Rick has begun installing W2IHY EQ Pus units, and these seem to make the Orions sound quite good. The IHY compressor is leagues ahead of the TenTec internal processor. This along with some transmit bandwidth contouring has really unmuddied the stations. There are EQ Plus units on 20 run and 40 run now, with 80 run coming soon, then 15 run. I will keep that circuit in mind for other uses, maybe with an Icom 7700. -lu-w4lt K3 # 3192 Date: Fri, 19 Nov 2010 11:15:02 -0800 From: Jim Brown j...@audiosystemsgroup.com Subject: Re: [Elecraft] Yamaha CM500 To: elecraft@mailman.qth.net Message-ID: 4ce6ccb6.70...@audiosystemsgroup.com Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 11/19/2010 5:48 AM, Luis V.

Before and after the contest, I may want to work SSB, so I made a simple connector adapter for my CM500 mic (8-pin mic plug, one resistor, short length of coax, to female TRS 1/8-in jack). Last night, I checked it out with the MP that's still in my closet as a backup rig. I had to turn down the mic gain a LOT, but K6XX tells me that it sounds fine. The resistor goes from the 8VDC pin on the mic connector to the MIC hot pin on the connector. I think I used 4.7K or 6.8K.

[Elecraft] USB to Serial Issues
I've noticed a number of post (hundreds maybe?) about folks having one problem or the other with serial to USB converters. I've had good luck with mine, a Belkin, but others have complained often about Belkin, and other types as well. I think the main problem is the computer itself, but that's a pure guess. In any event, for this and other reasons, I started keeping an eye open for a laptop with a serial port. It's not that I was having problems, but I couldn't help holding my breath every time I did an update to my K3. Actually, on one or two laptops I have had, there was a problem. Anyway, recently I spotted a deal on Buy.com for a Dell laptop (refurbished) which actually did have a serial port. To be honest with you, I haven't seen a laptop with a serial port for eons! This is a Dell D630, and it was less than $300 as refurbished. I've had good luck with refurbished products, so I decided to give it a try. It arrived today, and I had waited to update my K3 to the latest beta pending its arrival. It went like clockwork. Everything else seems to be working just fine as well. Point is, if you are really getting frustrated with USB/Serial converters, maybe this is something you might consider as well. I'm dedicating this laptop to my operating position. The serial port will be better anyway, for things like updating firmware, rig control, etc. Not a lot of glitz on this computer (no webcam, and a smaller hard drive), but it certainly seems to be a good choice for just dedicating it to ham radio operation. It does have a dual core processor, so it's not slow. I have been using a netbook (my XYL usurped my other bigger laptop), which I still like very much for travel, etc., but this really seems like a better arrangement--not sure why I took so long to come to that conclusion. The other thing I'm noticing, is that this computer is a bunch more stable. I think netbooks are just underpowered processor wise. They are great for the road, but that's about all. So, while I have been able to update my K3 with a netbook and USB converter, I think this will be a lot more dependable overall. Bottom line is this--if you are having problems doing your ham apps, it might be your compter is too old, or underpowered. Finding a laptop with a serial port isn't all that easy, but they are out there--much to my surprise. Hopefully I didn't buy a problem, but I think it will work fine. If either of those problems are what you are experiencing, check out the bargain basement on these websites from prominent dealers. A refurbished product usually has undergone a good bit of individual examination, so I feel fairly confident that it will perform. If the basic product was junk, then I'm toast! But I suspect it will turn out reasonably well. At least it has so far with my experience in such products.

Re: [Elecraft] USB to Serial Issues
Dave, Yes, I believe a dedicated hamshack computer is in order in this day and age. I will only disagree with you on one point - the choice of a laptop instead of one of the low profile desktops. Desktops are more reliable and are repairable if they go belly up. Besides, I hate the laptop keyboards - they drive me insane. If I use a laptop with an external keyboard and mouse, I might as well use a desktop computer. At this price point, there are a lot of refurbished and off-lease computers out there (both laptop and desktop) that can serve as a dedicated hamshack computer. I have found the IBM (Lenovo) off-lease computers to be a good value and have been quite reliable. I have 3 of them in use on my home network and there are 5 more that I support on my church network. They just keep chugging along and seldom give problems. Most are available with at least one (often 2) serial ports and Windows XP Pro. For those who are Linux oriented, some can be available at 2/3 the price without OS. Look around the web - Google is your friend - whichever you choose, laptop or desktop, a computer dedicated to the hamshack is not an enormous expense, and if you have a home network already, it just makes sense (to me anyway). 73, Don W3FPR On 11/19/2010 9:24 PM, David Yarnes wrote: I've noticed a number of post (hundreds maybe?) about folks having one problem or the other with serial to USB converters.

Re: [Elecraft] USB to Serial Issues
I have had zero trouble with a Quatech SS-USB-100 USB-to-serial in any application. That said, I'm using an Edgeport USB to four serial port adapter now on my Lenovo T400 (WIN-XP Pro) laptop. I have updated the FW in my K3 dozens of times with this setup. And I use LP-Pan or VSPE to run my SDR-IQ, N1MM, MMTTY and the K3 at the same time on one port and another logging program on my TS-870 with another port. Another option to consider with some laptops is a docking station. Some have legacy parallel ports, serial ports and additional USB ports. I would use the one for the Lenovo, but the security lock on the thing takes too much room. I have used docking stations on older Toshiba Tecras, in fact I still have an old 386 that I use with my N2PK network analyzer.

Re: [Elecraft] K3: USB port
I dare to argue with the below statement. I see several advantages in using laptop in the hamshack. They require less space They are usually less noisy both electrically and acoustically They do not need separate UPS And they are not that expensive after all. 1.6 GHz Atom processor netbook can be had for around 300 USD here and more then enough for everything needed in the hamshack (unless you need it for Skimmer or SDR) That does not mean that I support switching from RS232 to USB. I have Expert 1K-FA that is wired to listen on RS232 of my K3. Therefore I prefer we stay with RS232 for the time being. 73, Igor UA9CDC operating systems, I will continue to use them - I think desktops are more suitable for the hamshack computer than a laptop - they are less expensive and more reliable -as an example of one with 2 serial ports, see the 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

If you would choose a tower configuration desktop and place it on the floor under the desk (or mount the low profile desktop vertically), then the monitor, keyboard and mouse take up less real estate than a laptop. 73, Don W3FPR On 11/19/2010 11:03 PM, Igor Sokolov wrote: I dare to argue with the below statement. I see several advantages in using laptop in the hamshack. They require less space They are usually less noisy both electrically and acoustically They do not need separate UPS And they are not that expensive after all. 1.6 GHz Atom processor netbook can be had for around 300 USD here and more then enough for everything needed in the hamshack (unless you need it for Skimmer or SDR) That does not mean that I support switching from RS232 to USB. I have Expert 1K-FA that is wired to listen on RS232 of my K3. Therefore I prefer we stay with RS232 for the time being. 73, Igor UA9CDC __ 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] FTDX5000 Design Flaw
There have been a lot of comments on the reflector about the QST review of the FTDX5000. However, no one has noted a significant design flaw in the transmitter that shows up in the review. Refer to Figure 3 that shows the composite transmitter noise. It shows a noise level of -130 dBc/Hz from 10 kHz to 1 MHz (and probably beyond). This transmitter when combined with a full power amp could wipe weak signals in an entire amateur band for anyone living within a few miles of the transmitter (see the math calculation below). While a number of other transceivers have this problem, I wouldn't expect a top of the line $6K radio to have such lousy composite transmit noise. This problem is created either in the radio's synthesizer or its transmit amplification chain. The K3 was specifically designed to minimize composite transmit noise. The K3 QST review showed a transmit noise level of -155 dBc/Hz at a 100 kHz offset. This is 4 S-units less noise than the FTDX5000 at the same offset. This is not a theoretical calculation. I know of one case of composite transmit noise where an amateur transmitter wiped out weak signal reception across an entire ham band in a receiver located several miles away. -John KI6WX CALCULATIONS Assume that we have a FTDX5000 transmitting CW on 20 meters followed by a 1.5 kW amp. The transmit power is +62 dBm. At a 100 kHz offset, the transmit noise is -68 dBm/Hz. Assume that the FTDX5000 transmit output is fed to an isotropic radiator (0 dB gain) on top of a hill and we have a receiver also with an isotropic antenna in a valley with line of sight to the hill. For directional antennas, the sum of the antenna gains depends on where they are aimed and could be greater or less than the 0 dB in this example. For the moment, we'll place the receiver 1 mile from the transmit antenna. The path loss between the transmit and receive antennas is 60 dB, which implies the receive power of the transmit noise will be -128 dBm/Hz. The normal atmospheric noise on 20 meters is about -144 dBm/Hz, which means that the transmit noise will be 16 dB greater than the normal background noise. This noise will be spread across the entire band whenever the FTDX5000 is transmitting. If it is transmitting CW, the receiver will hear noise modulated in Morse code. If it is transmitting SSB, the noise will vary with the voice modulation peaks. The receiver would have to be more than 6 miles away for the noise to drop to background levels. Another way to look at this problem is how many S-units would the show up in a 500 Hz receive bandwidth. The total power in the noise is -101 dBm in the 500 Hz bandwidth. S4 is -103 dBm, so the noise would be about a S4 signal level. Each time you halve the distance to the transmitter, the noise will increase by 1 S-unit. If you live 1000' from a FTDX5000, you could see a noise level of S7. You can reduce the noise by using a narrower filter, but you would have to drop down to a 100 Hz filter to reduce it by 1 S-unit. This calculation was done with the transmit antenna on top of a hill so we could use free space radiation to calculate the path loss. If both antennas are on a flat surface of earth, the path loss will be somewhat greater, but the exact magnitude requires using antenna radiation software such as NEC-4. __ 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
