Re: [Elecraft] JT65 requirements, and a possible external reference-locking option for the KX3

It also takes up about 100 times more space, which is the real problem. But back to JT65. If it turns out the KX3's temperature compensation can't provide the stability you'd like, we could design an external 10- MHz locking module for it. This module would be called a KX3EXREF -- the equivalent of the K3EXREF, which does the same job for the K3. The only drawback to such a module is that it would have to be installed in place of the planned 2-meter module. It would use the SMA connector as the 10-MHz input. Would this be of interest? 73, Wayne N6KR __ 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] Interpretation of P3 display
Hi Harold, On 6/8/2012 2:45 PM, Harold V wrote: I have a question for the group regarding interpretation of the P3 display of SSB signals. Primarily I use it to spot stations on quiet bands or spot openings on busy bands. But I am trying to gain a better understanding of what it is showing me regarding the quality of signals as well. I have my P3 set up to show the band width as a column and the span set to +/- 25. I have noticed that most SSB signals will remain within the bounds of the column. However, some SSB signals will exceed the width of the column and will resemble a pyramid, occupying several kilohertz above and below the column on voice peaks. The proximity of the station does not appear to matter as these observations apply to distant stations as well as local stations. Is this what is known as splatter? Is the station overdriving their transmitter or linear? Is their ALC or compression too high? Is the frequency response of their microphone too wide? Send a captured snapshot using the P3 utility. On the water fall I see stations there their signal goes well past other signals. Yes, I see similar and I would call it splatter. Especially when it is clear other stations are not doing this. Over driving something past their SSB filters.

[Elecraft] thunderstorm early warning.. was: Living with EMP
Hi Drew, I have been running a Boltek long range lightning detector that is part of a network of detectors for tracking storms. Gives me range and bearing on strikes.

Could not find a single cable with sleeve as ground for the three cables that connect to tip and the two rings. I have yet to find what I think is a nice right angle 3.5 mm TRRS plug. did get several with a clip on plastic cover that will not stay straight. Also on my SignaLink I put in a small DPDT switch that I used to turn on or off the PTT ( and for switching between 1200 and 9600 bps packet lines) so just put that in the PTT circuit and turned it off.

Re: [Elecraft] cables for digital/dayton
Hi Bob, One of the Elecraft guys said they did plan to provide some sort of jumper cables. Maybe even they could provide right angle connectors of the various types used on the KX3.

That sounds like good advice and therefore I will leave it disconnected as well, as I certainly will be using the CAT cable at the same time anyway. Yeah, the right-angle connectors I purchased from Mouser have plastic covers that snap in place, that the moment a wire is installed through the cover, it cover unsnaps. That is the biggest advantage to buying a pre-made cable -- they are insert molded and strain-reliefed. I know that Elecraft has their hands full, but providing right-angle adapter cables, and perhaps prewired molded connectors with short unterminated cables for the Mic might be a reasonable thing to offer as an optional purchased Connector Kit. As you said, none of the TRRS cables I have found have the shield tied to the shell, and the quality of the blank connectors is dubious at best.

Re: [Elecraft] K3 psk31 transmit problems
Hi Frank, Does the K3 show any indication of getting the audio signal from your computer line out ( or speaker out) cable? You can put the K3 into TEST mode and not transmit while you are checking levels. Also you need to adjust the line in gain of the K3 to show the 4-5 bars on the ALC meter then set the power control for what ever power you want, like 25 watts. See the instructions in the manual on how to set this up. It is different than how to use other radios. I also presume you have selected line in on the K3 audio source menu. If you have a working serial cable then you can tell DigiPAN which port to use and to use RTS or DTR. Then make sure in the K3 you have turned on PTT for one or both of those two signals. You can test this with the K3 in TEST mode as well. I use fldigi and flrig using a serial cable and using PTT via CAT to work PSK31. Far more capable program than DigiPAN and pretty easy to use. Free also. DigiPAN is a really old program though the MixW web site says a new version is being worked on. 73, tom n4zpt On 5/19/2012 10:59 AM, kf4clo wrote: Hi All I want to thank everyone for thier help-I still haven't resolved the getting Digipan to key the K3 using the line in-line out,lineout-line in,but I'm still working on it.

Re: [Elecraft] OT: Dayton New Equipment Show
Hi Joe, Guess we will have to await independent testing. The Flex folks seem to assert they have the equivalent of more than 24 bit when dealing with adjacent strong signals. From the Flex reflector... Just in rough numbers, you get a 1/2-bit for every divide-by-two decimation you do. If you are looking at dynamic range in a 500Hz bandwidth (this is what we typically do). The math I generally use to get there is log(f1/f2)/log(2)/2. I just think this way as a programmer (do everything in base 2). So if you take log(245.76E6/500)/log(2)/2 you get 9.4 extra bits when added to the 16 gives you 25.5 bits (152.7dB dynamic range). This assumes all 16-bits of the ADC are good which is probably not a good assumption. I'd have to pull out the notes and look at the data sheet again, but this should give you a rough idea. Hopefully I haven't made an additional duh today myself! Bottom line -- there's plenty of dynamic range. Also, if you are interested, we are using Xilinx DSP48E1 blocks which use an 18x25 multiplier and so Xilinx tools generate the on-board DDS as a 25-bit DDS by default --- again to preserve the SFDR of the receiver. We could add extra bits, but 25 are fine for the same reason.

Hi David, We ( Vienna Wireless Society) have had multiple Elecraft K3s our for our field day. Did not seem any more difficult that other radios we have had out. I think there is a locked setting to limit amount of messing up the settings. We usually had someone around that knew how to reset the radios. But we had that sort of issue with a TenTec Orion and a FT-1000MP previous years. So no worse experience with K3s than any other radio brought out with those that did not own one. We used mono-band antennas for 40m CW and SSB stations and multi band antennas for our other two stations. Had two sets of band pass filters but discovered the K3s were just fine without. We have also had a 3 band Spiderbeam up on a 15 meter mast for the non-40 SSB station which got us a nice signal to the West. we do not like multiband antennas in general. lately we have been using two element wire yagis pointed towards the West coast ( we are in Virginia). 73, tom n4zpt On 5/11/2012 12:29 PM, dm...@nexicom.net wrote: I will have my k3 at Field Day this year and would like a little advice.I will have the Yamaha cm500, a hand held mic plus a set of paddles.

Re: [Elecraft] Portable Antennas (near end fed)
My experience in a hotel room is they do not work well at all. Seems like you are inside a cage with RFI emitters all around you. Even high up in the hotel.

The thought is that one could test out indoor antennas in their own shack to see how various things work. Second thought, particularly with respect to small loops, I wonder if they would be useful to home use (primarily as a receive antenna assuming the presence of better outside antennas for transmitting) being easy to rotate by hand to try to null noise or QRM. 73 - Mike WA8BXN ---Original Message--- From: va3...@gmail.com Date: 5/11/2012 11:27:40 AM To: elecraft-boun...@mailman.qth.net; k6...@foothill.net Cc: Elecraft list Subject: Re: [Elecraft] Portable Antennas (near end fed) I for one am in a quandary on what to get at Dayton A buddipole, Alex loop, or g4tph.

Also had bandwidth set to 600 hertz and tried to dial the center freq up to 2KHz but would not go there. 1.78 was the max I think. ( rig in basement and I am up where my email computer is ). Also noticed that when I had it in USB and cut back the Hi Cut the audio at about 3KHz went from 3KHz roll off to something like 2 KHz roll off even though the reading was 2.9 KHz.

Re: [Elecraft] K3-PSK/RTTY Question
Hi Bill, For my K3 I do just as you say. A serial cable plus two audio cables connected to the line in/out of my computer sound card and my K3. Tossed my homebrew interface I used with my FT-1000 in the parts box. However my laptop does not have line in/out and so far the KX3 does not have line in/out. I get odd noise that looks like hum plus some scruff when I connect my KX3 directly to my laptop. It works but do not want to transmit the noise. So some sort of isolation and level adjusting is needed beyond just the computer sliders and KX3 mike gain and speaker level adjustment. Seems to me that is. So for my KX3 I just picked up the TRRS and TRS right angle connectors and plan to hook up one of my unterminated SL-USB cables ( short Ethernet cut in half) to play. Given the SL-USB is in my go kit anyway with my laptop. May use one of the inexpensive interface boards I found on eBay with a couple transformers and transistor switch. Or just grab some resistors and audio isolation transformers out of my parts boxes, i.e. dust off my old interface board. So yes, with the KX3 seems an interface is needed.

Re: [Elecraft] Problem with Elecraft's built in 2 meter
Thanks Julie, Strong and weak are then their audio levels? Given that you are listening to the repeater output the RF carrier level should be the same for some that are fine and some that are clipping. Are all the ones clipping on the same repeater? Perhaps then strong means loud means higher deviation but not so as to clip the repeater receiver since I presume the same talkers are fine on your 706. My 706 had pretty wide FM filters, something like 20-30 KHz wide. ( we used to have a local repeater that clipped with excessive input deviation.) Using your panadapter are the ones that clip clearly wider than 13 KHz? Or offset? Perhaps the repeaters being used by those talkers are older ones with wide filters that allow wide deviation input? So is a puzzle. Strong and weak alike are fine on my K3 with internal transverter but my local repeaters are all on 15KHz centers and do not seem to be much wider than 13-15KHz on my P3 ( or my LP-PAN or SDR-I/Q ). I am wondering then if you have a bad filter? 73, tom n4zpt On 5/3/2012 10:31 AM, Julie Royster wrote: Larry K4MWE and I are hearing lots of distortion (clipping probably) on the K144XV tuned to local repeaters for anyone with strong signals.

In contrast, the same repeaters sound just fine on our old Icom 706. We had hoped to be able to use the K3 for all bands. Has anyone else had this problem?

Re: [Elecraft] Fw: KPXA100 amp for KX-3
Some time last year Eric or Wayne gave an approximate idea of size and weight they had in mind back then. I am presuming the K2 and K3 amps/tuners are a good volume/weight predictor just need to be re-laid out for the KX3. the two together was something like 4 x 5 x 9 and 6 pounds as an idea back then I thought. 73, tom n4zpt On 4/30/2012 6:47 PM, Don Wilhelm wrote: Bob, Sorry, but none of that information is not yet available.

It will be but I doubt if the process is far enough along that the projections you are asking about can be available. I am certain Eric will correct me if I am wrong.

Re: [Elecraft] SMT and the K3 - Nerves
Hi Lee, I replaced that SMT resistor with the supplied SMT resistor. Was pretty easy. Cut the old one in half in place, then unsoldered the two pieces. Then made sure the solder on both sides was good and cleaned most off. Was not much there. then tacked the SMT replacement in place on one side. Then was just touch the soldering iron on the other side to flow the solder ( might have added a spot of fresh solder.) Then soldered the other side and all was perfect. There is also plenty room to put in the other resistor resistor with leads per the instructions. I had a pair of fine tweezers with a rubber band to hold the SMT resistor while I did the tack on one side. Seemed to work well. Not much solder at all is needed. 73, tom n4zpt On 4/19/2012 10:18 AM, Lee Buller wrote: I have SN 443 - an early model of the K3. It has been back to Aptos for updates.

So while you can get cables and and/or adapters that will fit they just won't work. I haven't received my SVGA card yet but in preparation I conducted an experiment with my PC using a DVI adapter. I connected the VGA output of the PC to the DVI input of the monitor using a DVI adapter on the end of the VGA cable. The monitor won't recognize the analog signal on the DVI input. So here's what I did. My PC has both a VGA and a DVI output. I used the VGA output from the PC to drive the primary monitor. I then used the DVI output from the PC to drive the secondary monitor. I then put a VGA cable on the other input to the secondary monitor and have it in position to attach to the P3 as soon as UPS drops off the card. I only use the secondary monitor to display the VE7CC cluster program and there is a front mounted button on the monitor to switch between the two inputs. If your PC has a VGA and DVI output you can do exactly what I did with your single monitor. The only difficulties incurred were trying to get the PC display program to properly identify monitor number 1 and monitor number 2. I fiddled with it for quite a while but I don't remember what I did to get it right. You should have no problem with only one monitor.

The cable has a DVI-A while monitor appears to accept either a DVI-D or DVI-I, I'm not sure which it is. I gained what little I know about DVI from the internet. It would seem the DVI-A (analog) is the only connector that will work with VGA. But I could be wrong. A second monitor would be nice but due to available space I would prefer just one.

Hi Julie, I have not seen another list response. Perhaps you got direct responses? The split mode is not necessary for a repeater. See page 29 of the manual. I dial in the repeater on one of the VFOs, switch to FM mode, then push the Alt key ( hold down mode key) multiple times until it switches to the + or - offset I want. When I key the mike the VFO displays the offset transmit freq then goes back to the receive freq when I let off the PTT. Separately is an offset setting but as I remember it was defaulted correctly.

Re: [Elecraft] P3 SVGA
Mine came yesterday. Is installed and working with power from a 1 amp position on the station power strip. I am using one of my older displays at 1024x768 and still very nice. Will swap in one of my other wide displays later that has multiple inputs. Picture in Picture might be nice here. Or might pick up an SVGA frame grabber and see if I can stream the P3 video. I think I would like to be able to switch the filter marker to the U that I like on the main P3 display. Also seems that the display calibration is off by about 5 dB from the main P3 display so need to go read about calibration. result is that if the main P3 display is nice looking the waterfall on the external monitor looks too light as I can not see signals I am copying just fine. Otherwise very nice. 73, tom n4zpt On 3/12/2012 9:36 PM, Ed Schuller wrote: As noted by others, it went together very quickly.

Re: [Elecraft] K3 Internal Tuner Question
Not sure I understand this. I did not think an SWR meter was supposed to work properly only when seeing 50 ohms restive. If the line is not flat it is terminated in to something other than the feedline impedance, i.e. not 50 ohms restive in this discussion. I would expect the SWR meter at some point in the feedline to be accurate under those conditions because it is supposed to measure the standing wave ratio of the feedline with respect to that 50 ohm resistive. If I then have an antenna coupler in the radio that is matching the transmitter to that non-50 ohm impedance why would the SWR meter change to inaccurately measuring the SWR? Putting the K3 into bypass or letting it tune should not change the SWR measures at some point in the feedline. The K3 may show 1:1 simply because it properly transformed the line impedance to 50 ohms restive. Perhaps I am missing something here. Sorry for continuing the discussion. 73, tom n4zpt On 1/2/2012 8:06 PM, Rick Bates wrote: Let me see if I can correctly state, with clarity for all to understand so this thread can die peacefully and we can move on (please?). The K3 puts out power into an internal tuner (if installed) and then to an SO-239 at the rear of the radio. If the tuner is in bypass, the impedance is very close to 50 ohm resistive at that connector. In this case, any SWR meter (bridge) downstream to the antenna will read the SWR (AT THAT POINT IN THE FEEDLINE which may/not agree with the K3 reading). If the tuner is NOT in bypass, the impedance at the same SO-239 will be +-10:1 of 50 ohms. Since any other SWR meter (bridge) between the K3 and the antenna is probably NOT seeing the expected 50 Ohm impedance, the reading of OTHER than the K3 meter will be called into question and more than likely wrong. Repeating, when the internal tuner is used, the K3 meter is the only one that is accurate.

Re: [Elecraft] K3 Internal Tuner Question
Thanks Matthew. I should not have spoken like that.

Re: [Elecraft] Maxwell's Equations.
Does not offend me Jim! Was just puzzled. The math is hard having forgotten most of that myself especially as I only barely understood it back in college 40 years ago.

Re: [Elecraft] Ethernet serial servers... Re: USB to serial angst
Hi Matt, Certainly. and not the point. Seems hard to use the USB adapter when my computer is next to me and the Ethernet to serial device is across town or across the country. You can get Ethernet based USB servers but they have the same latency behavior.

I have a pair of the RemoteRig units that I plan to use with my TS-480HX where I can keep my control head with me where ever I am and use the radio back at home or at the family cabin. Am hoping it will be OK for SSB and sound card digi modes. I see they now have the Elecraft K3 listed as supported. http://www.remoterig.com/ I am not using these ethernet serial devices with my K3s but rather with TNCs or repeater controllers or other serial devices that do not appear care about delays.

Re: [Elecraft] Ethernet serial servers... Re: USB to serial angst
Hi Matt, I had the same need for serial ports but discovered I could get inexpensive PCMCIA serial and parallel port cards that worked exactly like built in serial ports or the docking adapters that fit my ThinkPad laptops. So ditched the USB converters. Once I get to go set up the TS-480 out in Arizona then I will start getting a feel for the RemoteRig. Then consider it for my K3 here at home. But as the K3 does not have a removable front panel then would need a computer on my local end where I do not need that with the TS-480 or the other HF rigs with removable front panels. But this is getting off of a K3 topic. Agree completely on latency. Getting low latency on a remote station might be too much until we can set the service quality on the entire path. 73, Tom n4zpt On 3/16/2010 2:32 PM, Matt Zilmer wrote: Hi Tom, Sorry, maybe I didn't say some of what I should have. My reasons for using Ethernet are similar to yours, at least when it comes to the K3. IP can be routed, where USB and serial (alone) cannot. This gives us the option of remote operation, the main goal. Whether for a K3 or other devices, the advantages may be the same. I haven't tinkered with the RemoteRig yet, but I've been thinking about it. A complete at-least-voice solution for remoting is my eventual goal. I agree that remote keying is probably not an option. I haven't even bothered trying that... Was just trying to answer Don's question about latency. Because of the buffering, it is more an issue than with USB. Serial is probably best of all - a dedicated interface with little overhead. If I had a serial port on ANY computer, I'd be using it on the K3.
