Re: [Elecraft] XV144 transverter firmware
Hi Bob, Thanks again for your quick response, don't know if you're part of the Elecraft team, if yes then congrats for that, excellent products with like everywhere some deficiencies to be corrected. One of these into your XVxxx transverters are the local oscillators which these days are out of scope of the actual technologies, specially due the digital modulations requiring much more stability than a single XTAL (even equipped with a heater). I'm going to replace the Xtal oscillator of my XV144 with a clean 116MHZ PLL synced 10MHZ, place a small smd PAT-2+ or 3+ (2 or 3db depending of my stock) pad behind the mixer LO input as I'm not sure the 50Z adaptation is perfect, and adjust the LO level at its maximum between 17 to 20dbm according the mixer datasheet to increase the IP3 to the max possible with this ADEX-10H mixer. I know these transverters have been designed many years ago for the k2 line, may be now it's time to revamp them a bit with some new technologies to improve their performances at a level of some other competitive products. For me the main advantage of these transverters is the interfacing/switching management within the k3 line and the nice packaging within the line but the RF performances are becoming a bit obsolete.

Re: [Elecraft] Microphone Qusestion
I use three different types of microphones on the K3, all with similar results - - Heil Goldline with H4 and H5 elements, for use in ham shack - Yamaha CM500 headset, for when the ham shack gets noisy - A cheap-o computer headset, very lightweight, for field work The main control to use in set up is the TX EQ. There are good guidelines from others on how to set the band gains up. Using the EQ, all three mics sounds about the same. For the EQ, I set the bottom three bands as low as they'll go (-16 dB), then bring it up to 2 dB at 400 Hz, and have some midrange gain through 3.2 KHz. The energy below 400 Hz is not useful for intelligibility. Others can advise you on exact settings, because they're audio pros. Their advice is worth following, imho. 73, matt W6NIA On Sun, 05 Jul 2015 06:59:42 -0500, you wrote: New to the Reflector and new to Elecraft with a K3S on order, what is suggested for a microphone.

Re: [Elecraft] Microphone Qusestion
Someone suggested the Heil PR 781 as a good choice. The Heil PR-781 is grossly overpriced. Any quality dynamic mic will work very well with the K3/K3S. For a hand mic look at a Kenwood MC43S (connector matches the K3) or Shure 514B or 596B ($43 at BH Photovideo). For a stick mic to be mounted on gooseneck/boom, look at a Shure PGA48 ($35 at BH Photovideo). If you need an off the shelf amateur mic, the Kenwood MC60A works fine if you keep the internal preamp turned off (otherwise it requires a minor rewiring of the mic plug). Other manufacturers communications/paging mics can be substituted for the Shure but they are a good value for reasonable quality. 73, ...

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.

Re: [Elecraft] Microphone Qusestion
I use a Shure 514B - bullet proof handmic with no switch noise and excellent audio properties. Tailoring of the TX EQ completes the job. Hint: Have one or two trusted friends listen to your signal while adjusting the EQ - they know your voice and what you should sound like. Too much help will just muddy the waters. Want a good desk mic? Anything you can put in an arm will do (gets it off the desk) - and the EQ does all the rest. No need to spend mega dollars (that is what you have a K3/K3S for).

Re: [Elecraft] KRC2 relay control
Byron is on the right track here. The best way to control the KRC2’s ACx pins is to do it through the K3’s menu. The KRC2 is listening to the K3 to get band and status information, and not necessarily to a computer. So setting the state in the K3 will cause it to be changed in the KRC2. Take a good look at the K3’s MN command, specifically MN049. I suspect that testing with the K3 Utility’s command pane will quickly show you the correct command to do what you want. From there is is a pretty simple matter to plug the command into N1MM+. By the way, the K3S/K3//KX3 Programmer’s Reference has been seeing a lot of update activity recently. If you haven’t downloaded the latest, you may be missing out on some interesting stuff.

Re: [Elecraft] K3 Autotuner malfunction
After getting some data, and considering what others had to say, the answer seems to be that there is no malfunction. The behavior that I am seeing is likely because the mismatch with the antenna is marginal. At least my K3 is not very sensitive to VSWR less than 1.5:1, and it reports a VSWR of 1.0:1 when other devices are measuring something more. In general it reports a lower VSWR than any analyzer I have tried. Addressing my problem on 40 meters, there are good values in the tuner memories for the whole band, but if I change from the high end of the band to the low end, the VSWR sensed by the K3 is not so bad, and I suspect that the K3 doesn't bother to switch to the values in memory for the new frequency. I might like to see less than 1.5:1.0, but the K3 isn't bothering with it. On 80m, my antenna actually does need a bit of tuning. There has been some trouble auto-tuning to get a good match with the tuner around the part of the band where the tuner capacitor needs to switch from the antenna side to the transmitter side or vice versa. This is just a theory, but possibly the K3 sensing of the match is more sensitive depending on which side the capacitor is on. Maybe it makes a mistake sometimes when the SWR is relatively low, like less than 3.0:1. The capacitor seems to end up on the antenna side when there would be a better match if it switched to the transmitter side. I may mess around on 80 and see if I can learn anything else or confirm this. Regardless, my tuner works, and if you use it correctly, there is barely a hiccup.

Re: [Elecraft] Microphone Qusestion
Microphones have to suit your voice. No, microphones need to be reasonably flat without excess low frequency response, particularly when worked close. Beyond that the K3/K3S TX EQ and noise gate are all anyone needs to achieve excellent sounding audio with any voice. Start with TX EQ set to -16, -16, -6, 0, 0, +3, +5, +6 and touch up the 200 Hz band for your particular voice. Increasing level at 200 Hz will provide a bit more low frequency response at the cost of some punch and intelligibility (low frequencies waste transmitter power). For the DX sound, change +3, +5, +6 (3 dB per octave pre-emphasis) to +6, +10, +12 (6 dB per octave). Both the low and high frequency adjustments may change a bit depending on the response of the microphone. A communications (e.g. paging or radio) mic will need less pre-emphasis as some is built into the mic element. A recording mic will need even more low cut because of proximity effect (bass build-up). 73, ...

Re: [Elecraft] XV144 transverter firmware
Hi Don, Thanks for your response Don, the design of these XV transverters which have been done many years ago for the k2 line is something I understand perfectly. Since this time the technology has moved up, this is the reason why I decided to improve mine. However once more the design of the packaging (flat, light, pretty... ) and the integration into the k2/k3 line is excellent, this daisy-chaining is perfect, avoiding externally complex and ugly cabling. The shame is there is no 23cm transverter into this XV line, probably I'll integrate one of my 23cm transverters into an XV144 I'll depopulate keeping the IF and control logic parts. My goal is to replace my IC910H (2m/70cm/23cm) with the k3 plus XV series, but with improved performances. You're doing an excellent job guys (Elecraft team), continue going up, we love this.

Re: [Elecraft] Microphone Qusestion
The point is that nobody can tell the difference on the air between a $35 Shure PA48, a $65 Heil HM-12, $155 Heil PR-781 or even a $390 Yaesu MD200A8X for that matter. We've all wrapped a Solo Cup or cut off paper towel tube around a Shure 444 or Kenwood MC50, etc. if we've been licensed long enough. Many of us have soldered capacitors in series with the mic lead over the years as well in order to fix audio deficiencies in older rigs that did not have effective TX EQ or proper preemphasis - that doesn't take anything away from those mics. However, the TX EQ in the K3 is probably the most effective, simple to use option and it certainly makes the audio racks and W2IHY every expensive surplus. 73, ...

Re: [Elecraft] KRC2 relay control
A bit more on this. Sending MN049; to the K3 puts the K3 into the Menu mode with the KRC2 item selected. The VFOA display will show the status of the KRC2 ACC pins, read directly from the KRC2. You can then issue UP; or DN; commands to change the KRC2 ACx pin setting. It will advance (or decrement) by one for each UP (or DN) issued, rolling over when it gets to the end of the sequence. You can read the LCD with the DS; command to tell what the AC state is. Issuing MN255; will get you back to normal operations. Be sure to refer to the K3S/K3/KX3 Programmer’s Reference to get the details as to how to issues these commands, they can be a bit convoluted, especially when playing in the menus. If you are adding the commands to N1MM, you probably want to use 2, the first to turn on ACC1: MN049;UP;MN255; the second to turn it off: MN049:DN;MN255; This can be a lot more involved if you use the AC2 or AC3 pins as well, and using the KRC2 with AC binary coding (jumper W4 installed) makes things far more complex. Note that external control of the ACx pins requires use of the AUX I/O connection to the K3/K3S. The KRC2 does not have any commands to change the ACx pins using the serial port, nor does the transceiver have the ability to make that request using the serial port instead of Aux I/O. - Jack Brindle, W6FB On Jul 5, 2015, at 10:47 AM, Jack Brindle jackbrin...@me.com wrote: Byron is on the right track here. The best way to control the KRC2’s ACx pins is to do it through the K3’s menu. The KRC2 is listening to the K3 to get band and status information, and not necessarily to a computer. So setting the state in the K3 will cause it to be changed in the KRC2. Take a good look at the K3’s MN command, specifically MN049. I suspect that testing with the K3 Utility’s command pane will quickly show you the correct command to do what you want. From there is is a pretty simple matter to plug the command into N1MM+. By the way, the K3S/K3//KX3 Programmer’s Reference has been seeing a lot of update activity recently. If you haven’t downloaded the latest, you may be missing out on some interesting stuff.

Re: [Elecraft] Microphone Qusestion
My two bits… I use the Elecraft MH2 microphone and it suits me just fine. Although, I do admit to being mostly CW so the mic is not the most important part of the hobby. But, I get very good audio reports and even though I agree with all the comments about using TX EQ to make adjustments, I have actually never done that. I keep putting that off. Maybe I will do that soon. But, like I said, the MH2 is very good in my opinion and it has several advantages: nice PTT button on the mic is my preferred mode of operation and it does not take up space on the desktop because I just scoot it out of the way where it hides most of the time. 73, phil, K7PEH P.S.

Hi Tom, I'm taking these off Bob's hands, mostly for the KXV3A. I'll eventually get the new version, but I've been meaning to update my old pre-B module for years, and I've already got the preamp. I plan to upgrade my K3 as much as possible, since I got it cheap used and can justify what it'll cost me to upgrade it vs. buying a similarly configured K3S at $4500, but I'm going to take my time doing it, and I'd rather have the new KIO3B I/O board than the KXV3B right now. (I'd need to put $2K into my K3 to reach the K3S replacement cost, so I've can certainly do some upgrading.) I haven't figured out what to do with the KSYN3.

Or at least save your pennies. But how many times in the history of the K3 could this board have failed —short of storm damage. I look at the old synth on the shelf mocking me with its bright shiny aluminum shell and the only thing that keeps me from tossing it the trash is guilt so I wait until the next county mobile electronics collection when I get rid of my other old electronics, batteries, CFL bulbs, paint, etc. But, if someone wants it, tell me a really great thing you will do with it, promise to send me a picture of the completed project and I’ll even pay the US postage (note that if you just want the nice piece of aluminum, that doesn’t qualify).

Re: [Elecraft] K3: Old KSYN3 and KXV3A Boards
Ah behold the misplaced modifier :) Seriously, I would LOVE to hear if anyone takes Bob up on that offer. I have my old synth and I cannot imagine a case where someone would need one of these. If you had a failure now and needed to replace it, you would surely just replace it with the new one. Or at least save your pennies. But how many times in the history of the K3 could this board have failed —short of storm damage. I look at the old synth on the shelf mocking me with its bright shiny aluminum shell and the only thing that keeps me from tossing it the trash is guilt so I wait until the next county mobile electronics collection when I get rid of my other old electronics, batteries, CFL bulbs, paint, etc. But, if someone wants it, tell me a really great thing you will do with it, promise to send me a picture of the completed project and I’ll even pay the US postage (note that if you just want the nice piece of aluminum, that doesn’t qualify).

Re: [Elecraft] XV144 transverter firmware
Pierre-Francois, F5BQP: Substituting the xtal LO with a PLL will solve the frequency drift issue. One caveat is making sure the PLL has low phase-noise as that affects ability to handle strong adjacent frequency signals when trying to copy weak signals (which is why you are using JT65). One of the shining parameters of the K3 design. I had DEMI transverters long before I acquired my K3/10 (and KX3) so have continued to use them. I have heated xtal osc on 144 and 222 but use a PLL on 432, 1296, and 3400 MHz. Recent re-design by DEMI has improved xtal LO frequency stability while the xtal oscillator has excellent phase-noise performance. I see about 7 to 10 Hz drift on the 101 to 194 MHz xtal oscillators in the new L-series of DEMI transverters. But LO's for higher bands multiply the xtal oscillator frequency which also multiplies drift. For 432 and higher I found using the N5AC ApolLO PLL's worked well in DEMI transverters. The N5AC Apol series is not the lowest in phase-noise so that could be a real concern for those doing VHF-plus in high density RF environments. So one should consider phase-noise when deciding on a PLL. W1GHZ has a new VCXO design that exhibits lower noise than a PLL. Of course this is for the experimenter ham who DIY. I do think there will be a increasing use of PLL in VHF and higher equipment due to demands of digital modes and need for better frequency stability on the higher bands. One issue is the need for an external 10-MHz reference. That is not hard to embed into current equipment. I did that for a 432-MHz transverter customer. 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] Microphone Qusestion
A little OT, but Joe is sooo correct. Starting college, I worked at an FM station as a member of the TX engineering crew and a board op. I had the sign-on shift 3 days a week and was the only one there ... and I should probably include I was 16 and the engineering crew had minimal adult supervision. The mic at the board was the iconic prismatic RCA velocity mic, quite big and I found that, if I crawled up to it real close while reading the sign-on script, I sounded like a 45 yr old bass, highly experienced announcer instead of a 16 yr old teenager. I think this is true for most mic types, that velocity mic just may have been the extreme case. While bass is nice on a 50 Hz to 15 KHz hi-fi broadcast channel playing classical music [think 1812 Overture], you don't want that on a comm channel. K3 TX EQ is extremely effective in tailoring the audio from most any mic. I wonder how it would do using a Bell T-1 carbon element from an old black telephone? 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 7/5/2015 11:13 AM, Joe Subich, W4TV wrote: Microphones have to suit your voice.

Booting up KX3 and KXPA100 with external DC and then unplugging the external DC from KX3, KX3 continues to drive KXPA100.

Re: [Elecraft] K2 w/100W amp has temperature related xmit shutdown
Jim, That sounds like the classic problem that is produced when the KPA100 diodes D16 and D17 succumb to static coming from the antenna. The K2 has a loss of power control and will try to transmit at the maximum power possible. You would see that if you connect an external in-line wattmeter and set the power knob to somewhere between 20 and 40 watts - I suspect the actual power output would be in excess of 120 watts. You will also likely see HiCur messages - and that is causing your shutdowns. You can 'take my word on it', or you can use an external wattmeter to verify that you have no power control and the power output is always at the maximum the K2/100 can deliver. Replacement of D16 and D17 in the KPA100 is in order as the first step. There are other failure points in the KPA100 power output reporting to the base K2 MCU that can cause similar responses (failure of KPA100 U6), but the most common problem is D16 an D17 which can be damaged by static charges on the antenna feedline. If the problem does resolve to the failure of D16 and/or D17, you might want to consider measures to prevent future failures. Put a DC path across each antenna feedline to bleed off static. A non-reactive 5k to 50k resistor will do fine. Then disconnect antennas from the K2 when not in use - a switch to connect the K2 to a dummy load is ideal. 73, Don W3FPR On 7/5/2015 7:28 PM, wa4ywm wrote: I have a K2 serial no. 4729 with the 100W amp which I have been using for almost 10 years.

Re: [Elecraft] KAT500 won't tune the 6 meter antenna
Yes. Check the KAT500 specs on page 2 of the KAT500 manual. The tuner is limited to matching no more than a 10:1 SWR in the HF range, and lower at VHF. Note that this is specified for 500 watts of power, so you may be able to get a little more. 13:1 indicates a very bad match, however. You will be burning up most of your TX power in the coax between the tuner and the antenna. By far the best thing you can do is to fix the antenna so that is presents a much better impedance to the feed line (and thus the tuner). Doing so will get much more of that precious power into the air. - Jack B, W6FB On Jul 5, 2015, at 3:15 PM, George Rebong ke6t...@gmail.com wrote: My KAT500 doesn't tune my 6 meter antenna.

Re: [Elecraft] K3 and 48,000 Hz Digital Issue
Nobody??? Am I the only K3 owner using a Tascam sound card and a Mac to run WSJT-X?? Jim Bennett / W6JHB Folsom, CA On Jul 4, 2015, at 12:30 PM, James Bennett w6...@me.com wrote: I posted this on the WSJT-X Yahoo group and still no resolution. Hoping that perhaps someone on this reflector might have some thoughts on the problem. It isn’t a real “problem” per se, as I can certainly use my system as it is, but just wondering about this “quirk”. Here is my post: I just recently upgraded from WSJT-X 1.4.0 to 1.5.0 and have a question about something in the User Guide. I'm running on an iMac, OS X 10.10.4, an Elecraft K3, and my sound card is a Tascam US-125M. I am able to use the K3 and the new version of the software but have an issue with the documentation procedure…. The WSJT-X user manual says to use the Apple Audio MIDI Setup utility to configure the sound card to 48000 Hz, two channel, 16 bit. I have been using the above configuration at 41000Hz with no problems. When I try running at 48000 Hz, the radio does not go into transmit mode. If I switch it back to 44100 Hz, it works OK. The specs for the US-125M indicate that it should work up to 48000 Hz. When set to 48000 Hz, I’m able to get the usual decodes, but can’t transmit. I’ve got it set for the K3/KX3, and CAT control. Any idea why I'm limited to 44100 with this configuration and why 48000 fails to work?

One caveat is making sure the PLL has low phase-noise as that affects ability to handle strong adjacent frequency signals when trying to copy weak signals (which is why you are using JT65). One of the shining parameters of the K3 design. I had DEMI transverters long before I acquired my K3/10 (and KX3) so have continued to use them. I have heated xtal osc on 144 and 222 but use a PLL on 432, 1296, and 3400 MHz. Recent re-design by DEMI has improved xtal LO frequency stability while the xtal oscillator has excellent phase-noise performance. I see about 7 to 10 Hz drift on the 101 to 194 MHz xtal oscillators in the new L-series of DEMI transverters. But LO's for higher bands multiply the xtal oscillator frequency which also multiplies drift. For 432 and higher I found using the N5AC ApolLO PLL's worked well in DEMI transverters. The N5AC Apol series is not the lowest in phase-noise so that could be a real concern for those doing VHF-plus in high density RF environments. So one should consider phase-noise when deciding on a PLL. W1GHZ has a new VCXO design that exhibits lower noise than a PLL. Of course this is for the experimenter ham who DIY. I do think there will be a increasing use of PLL in VHF and higher equipment due to demands of digital modes and need for better frequency stability on the higher bands. One issue is the need for an external 10-MHz reference. That is not hard to embed into current equipment. I did that for a 432-MHz transverter customer. 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.com Hi Ed, For this improvement I've an EXCELLENT PLVCXO 116MHz which is used intensively in Eu by microwavers, the PN is excellent, even more, I've measured it very recently with an APPH AnaPico source analyser ( www.anapico.com ) . I'm going to build an external enclosure box where I'll include the 116MHz LO for the XV144, the 404MHz LO for the XV432 and a small internal 10MHz distribution amplifier . I'll not remove the existing LO of the XVs, just two SMB bulkhead on the back panel for the in/out LO (SMA are too large for the remaining space), so it would be possible with a small smb jumper to come back to the original LO. There is not enough space inside the XV box to include the PLLCXO without depopulating the initial oscillator, and I don't want to do it. Will need to know the RAL paint number of the XV enclosures, if someone knows it I will appreciate. I would have preferred a XV empty enclosure but I doubt I could purchase one to ELECRAFT so I'll repaint my own enclosure (will not purchase another XV just for the box... Lol...) Concerning the 10MHz most of my radio equipment are driven with the same GPSDO 10MHz distributed from the cellar to the tower for microwave transverters going to be installed soon on the tower itself and to the shack for the radios. The lab has another GPSDO or a rubidium PRS10.

[Elecraft] K3 Getting AFSK RTTY mode to Stick
Has anyone experienced this? I have tested using DXLabs Commander directly and through LPBridge, N1MM direct and through LPB and the results are the same. Put the rig into AFSK A 45 BPS using the software, check data mode using the DATA MD button and it is correct. Press AB button twice, the frequency is transferred but the A B all never comes up. Swap operating VFOs and the mode is now DATA A, swap operating VFO's again (Should now have the original frequency and mode of AFSK A 45 BPS) the mode is now DATA A. Further testing reveals that this will occur just by changing VFOs using the A/B button. If you set the mode using DATA MD and the VFO B knob then Press AB button twice the frequency and mode is transferred to the B. More testing shows that changing the mode using DATA MD and the VFO B Knob actually changes the mode in both VFOs/Receivers. I then tried setting the mode in both VFOs using the following commands in a DXLabs Commander Macro. (The PC020 is to give me 20Watts output) 'k31;md$6;dt$1;bw$0040;is$2210;md6;dt1;bw0040;is2210;PC020; This sets the VFO A to AFSK A 45 BPS, if I put the VFO B/Sub receiver commands second then VFO A resets to DATA A. Please what am I doing wrong? I would like to be able to select RTTY and have both VFOs in AFSK A 45 BPS. Please no responses saying I should be using FSK.

Re: [Elecraft] Microphone Qusestion
Hi think Jim and Joe nailed it with regard to Mic (sound) and associated cost. Heil do nothing for me. The price turns me off and as others have stated the K3 EQ is there to allow us all to use a sensibly priced Mic with good quality resultant audio which is what we all want. (Thats an assumption on my part ok) I won't rant about the WI2HY. I will say i have yet to hear a station using this type of audio that was adjusted to give good audio. My ears are c#@p but a wide signal is still a wide signal and awful audio is still awful. Piercing audio may cut through, but ripping off my headset when they call sends me to the coffee machine and medicine drawer. It does not get a reply from me. I use a CM-500 and an MH2 and sometimes an old Turner +3. Never had any complaints and I was born with a less than a DJ quality pitch. Oh well, thems the breaks eh?
