[Elecraft] FS: pre-made NUE-PSK modem cable
Hello Group, The following pre-made NUE-PSK modem cables are surplus to my requirements: 1 x Type 10 for K3; 1 x Type 23 for KX3 The cables were used a few times and in excellent condition. Price is USD 12 per cable including shipping to major cities of the world by airmail. If interested, please email me off the list vr2xmc at yahoo dot com dot hk If you buy both of them, then the total is only USD22 because there are some savings in shipping. 73 Johnny VR2XMC __._,_.___ Reply via web post Reply to sender Reply to group Start a New Topic Messages in this topic (1) Visit Your Group* New Members 2 • Privacy • Unsubscribe • Terms of Use . __,_._,___ __ 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] RadioSport Headset - Which Mic Element
The Heil Proset! I bought one, ridiculous price for poor quality! This is the only headset that has ever broken on me.

Re: [Elecraft] KX3 Extended VFO temperature compensation procedure
Anybody else having issues with non-linear oscillator changes around 40C? I've done the extended temp calibration 3 times (each time takes about 2 hours), and someplace between 38C and 42C the calibration goes crazy. Up to that point as the temperature gradually increases the tone shifts lower. But around that 38-42C spot it start rapidly shifting up in tone and down in tone (frankly all over the place). When you actually use the KX3 it is obvious that there is something bad happening around there because you can hear signals start to wildly drift around in the receiver as the rig temp moves through that range. That makes me think that the values obtained by the calibration process are not accurately reflecting true changes in internal oscillator frequency. I contacted the factory. Their best advice was to do the calibration again but use an electronic heat source (like a 50 ohm dummy load) under the KX3 with a variable power supply running the dummy load to get a more linear temperature increase. I haven't done that yet, but my three prior attempts have had a pretty linear temperature increase (one changing the rig temp about 1C per minute from 15C up to 60C). 73, Bob, WB4SON __ 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] KX3 Extended VFO temperature compensation procedure
I noticed something similar last night when doing this. I've not operated since so I don't have any experience with the result. At temp of 45 deg or thereabouts the tone started back up. But it didn't rapidly shift or do anything bizarre, just increased slowly as the temp went to 52 deg. Then I locked in the compensation; have to do RefCal today. I was surprised that the tone didn't just keep going down until temp reached 52 deg. It would be good to know if this is normal or I need to redo the temp comp procedure (hopefully not). 73, Phil w7ox On 3/18/14, 7:37 AM, Bob wrote: Anybody else having issues with non-linear oscillator changes around 40C?

Re: [Elecraft] KX3 Extended VFO temperature compensation procedure
Glad to know I wasn't the only one. In my case the issue around 38 to 42C is a big deal because that is where the PA sits when running JT65. So it makes that mode unusable. If the odd break didn't happen until 52C I'd be all set. And it was definitely hopping all over the place (sometimes rising, other times lowering, and in larger step changes than I was seeing before). I'm not so sure this isn't a problem with the radio locking onto a harmonic of the tone as it shifts lower and lower in pitch.

[Elecraft] Al-572 and KXPA100
Regarding keying another amplifier from the KX3/KXPA100: There is a problem currently being addressed beyond the (electrical specs of current and voltage) capacity of the PTT line to key another amplifier. Currently the KXPA100 cannot be used to key an amplifier with slow frame relay TR switching. The SWR detection cicuitry in the KXPA is too fast to allow the external amp (non-QSK) to go to transmit without tripping out on ANT FAULT. If you want to drive an amplifier with non-QSK relaying you will have to use manual PTT to key the amplifier to transmsit before giving it any RF power. I understand our Heros at Elecraft are working on incorporating a menu adjustable timing delay to allow VOX keyng without the ANT FAULT problem.

Re: [Elecraft] KX3 Extended VFO temperature compensation procedure
Mine didn't do anything so wavering as yours and it changed at a higher temp. So I wouldn't expect to see much effect while operating, since it was at high temps, above 42C. My concern is if the calibration is off. If it was a simple linear fit then it could be. If a table look up or more complex fit then it should still be good at a normal operating temp range. 73, Phil On 3/18/14, 8:18 AM, Bob wrote: Glad to know I wasn't the only one.

Also -- I haven't done any digital/data modes with my KX3 as yet, and may not (have a K2/100 and a K3/100 which may be more favorable for that than a barefoot KX3).

Re: [Elecraft] Al-572 and KXPA100
This isn't a problem with the KX3's SWR detection circuitry. If it is detecting a high SWR, it's because the KX3 is producing RF output before the t/r relay has closed and the relay is hot-switching. The SWR detection is doing its job and protecting the KX3 and the amplifier! The solution is either to speed up the amplifier's relay or add some more delay before the start of RF generation after the assertion of PTT by the KX3, as you say.

Re: [Elecraft] K1 construction manual for Rev D and earlier
try here: http://www.elecraft.com/K2_Manual_Download_Page.htm#K1 look for: K1 Manual (.pdf)(5.1MB) K1 Owner's Manual, Rev I, April 15, 2011 then look on page 48 of the pdf (page 47 in the manual) where it says: quote Transmit Offset Adjustment Locate the offset test switch (S2) on the bottom of the RF board. Place it in the TEST position. You should hear a tone in the headphones; its pitch is equal to the transmit offset. If you don’t hear a tone, try rotating C13 (back left corner, near the key jack). Using the menu, locate S T P (sidetone pitch), and go into edit mode to turn on the sidetone. You should now hear two tones: the sidetone and the transmit offset tone. If the sidetone is very weak or very strong compared to the transmit offset tone, use the S T L menu entry to adjust the sidetone volume. Note: The receiver is muted in S T L edit mode, so you'll have to return to S T P after making any change to the sidetone setting. Adjust C13 so that the transmit offset pitch is as close as possible to your selected sidetone pitch. The two will seem to merge when the pitches are matched. Exit the menu, and set S2 back to the OPER position. If necessary, use the C A L menu entry to calibrate the operating frequency on transmit (see page 41). /quote On 3/18/2014 12:53 PM, ke...@arrl.net wrote: Does anyone have a PDF of this older manual, in particular the section on setting the transmitter offset?

Re: [Elecraft] K1 construction manual for Rev D and earlier
Ken, Sorry, I do not have an older K1 manual. If anyone has a pdf copy, I would like to have it too. I can tell you how I set the TS offset on these older K1s, but it does take a few extra pieces of gear. I use a signal generator (another transmitter working into a dummy load will do) to produce a signal and receive it (zero beat) at the K1 sidetone pitch on both the K1 and a monitor receiver. Then without touching the K1 VFO or the monitor receiver, I transmit (into a dummy load) and set the TX offset so the pitch is the same on the monitor receiver. I do play the monitor receiver into the soundcard and view the audio pitch using Spectrogram to make certain the pitch is the same, but you can do the same by just zero-beating the signal in the monitor receiver - tune the TX offset capacitor until it is zero best. 73, Don W3FPR On 3/18/2014 1:53 PM, ke...@arrl.net wrote: Does anyone have a PDF of this older manual, in particular the section on setting the transmitter offset?

Re: [Elecraft] KX3 Extended VFO temperature compensation procedure
I have been following this thread with interest. Given our change in living arrangements, from a house with plenty of space for antennas to an apartment with no place for antennas, we are forced to do mobile and portable operation. In that case we can no longer easily operate our K3/P3 and have been considering getting a KX3 instead.

[Elecraft] KX-3 Receive Problem
Greetings, I am attempting to help a ham friend with his KX3 (s/n 631) which has a low receive issue. He says that the receiver became almost deaf after upgrading the firmware to the latest issue. I noticed that the radio had been dropped and the BNC connector is not square with the case. My friend says the low receive issue popped up a long time after the radio was dropped. I opened up the case and checked the BNC center pin to the ANT connector on the ATU and it looks and measures OK at 0 ohms. This KX3's options are: ATU and Roofing Filters. I applied my old XG-1 generator (7.040 MHz), 50 uV position to the ANT jack and the S-meter reads appx S2 w/ PRE Amp ON. With PRE Amp set to OFF, I can barely hear the tone. The KX3 is set to CW mode and I use the CWT to tune it in. This test was performed with the ANT tuner in the bypass mode. I verified the level of the XG-1 by applying it to my Icom transceiver which reads S-9. My own KX3 reads ~ S-8 with PRE Amp OFF. I rolled the software back to ver 1.61 / 1.23. I get the same poor receive results. I saved the radios Configuration, performed EEINIT parameter Initialization, then restored the config to the radio. No Joy- still low receive. I removed the Antenna Tuner and plugged the BNC jumper into the main board with no receive improvement. The KX3 seems to transmit well. I can transmit more than 10 watts into my OHR WM2 (terminated with dummy load). I have only tested the low receive issue on 7 MHz CW, but my friend says it is deaf on all bands. Maybe I missed a menu option to check. Any advice? Please.

Re: [Elecraft] KX3 Extended VFO temperature compensation procedure
At this point I wouldn't characterize my experience as a concern. So far as I can tell the calibration worked well, though I was surprised to see the tone vs. temp behavior above about 45 deg-C. My impression is that the calibration is done with a table, so such nonlinear behavior should not be an issue, so long as it is repeatable. The post by Bob, WB4SON early today in this thread described some crazy behavior which would concern me. Of more concern in such modes might be the power limitation at higher temps. There is some temperature at which the PA power will be limited. I don't know if that limit is of concern for JT65 operation or not. I know there have been discussions in the Yahoo KX3 group about different ways to add cooling to the KX3 for portable ops -- including fans, larger heat sinks with fins, and in one case leaning a cold cooler against the rig. 73, Phil w7ox On 3/18/14, 11:39 AM, Jack wrote: I have been following this thread with interest.

[Elecraft] Computer won't connect with kx3
I received my KXPA100 with tuner and hooked it all up. I use macloggerDX for logging and connection to my kx3. I plug the computer into the kxpa100 where it shows but the computer does not find the kx3. I check the serial port and it is the same I was using before. I downloaded the driver again and still not making a connection. I then tried connecting directly to the kx3 but still not finding it?

Re: [Elecraft] Computer won't connect with kx3
Roger, That sounds like you might have a bad KXUSB cable. You may have 2 of them, one which came with the KX3 and another that came with the KXPA100. Try both of them on the KX3 alone. If it works there, then introduce the KXPA100 to the same cable. Do not change USB jacks - often the operating system will change the assigned COM port if you change the USB port that the cable is plugged into. 73, Don W3FPR On 3/18/2014 3:23 PM, Roger Brisson wrote: I received my KXPA100 with tuner and hooked it all up.

Re: [Elecraft] KX3 Extended VFO temperature compensation procedure
Having run my KX3 in 40'C ambient temp just for ssb or cw and the odd bit of data and seem high pa temps and the kx3 folding back you absolutely have to consider better/decent cooling if you seeing pa temps consistently at this level. You trying to run at 10W non stop then wind the power levels down? Running at this level with high temps is a bad idea without better cooling. A simple extra external heatsink can be added to the current heatsink plate, with or without fan cooling and that should make a huge difference. Or Use the KX3 at 1-3 W and add a PA. 72 Dom M1KTA On 18/03/2014 19:19, Phil Wheeler wrote: At this point I wouldn't characterize my experience as a concern.

[Elecraft] Harris Platinum I TV amplifiers for 50 or 70 MHZ
Just in time for Es season!!!Add another 20 dB to your 6m or 4m signal! I just obtained some surplus (although like new - only used for four years before removed from service) Channel 3 (60-66 MHZ) amplifier modules. I have tested them all and they put out 900-1000w into a dummy load on 6m with around 10w of drive, so should work equally well on 70 MHZ (if you are in Region 1). I have not fiddled with the protection trimmers inside to see how high the power will go beyond the 900-1000w. I also have two driver modules that put out over 500w on 6m with less than 500 mW drive, in the event you have a very lowpower transverter or transceiver. In addition, I was able to obtain a number of Harris RF output connector cables and special plastic Power Connector blocks (with the built-in BNC power input connector, PTT line, plus the ground and B+ lines). Those will make it easier for those who don't want to do any mechanical alterations to the rear panel of the units.Note that you still will need to add cooling fans, a 48 to 50 VDC power supply, coaxial relays and a low pass filter. All the info has been updated on the web page here: http://www.bigskyspaces.com/w7gj/HarrisAmps.htm I am making them available for $400 each ($350 if you purchase two), F.O.B. Frenchtown, Montana. If you want the Harris RF cable and special plastic Power Connector, I will add them for $50 per unit, for as long as the supply holds out. Shipping, professional boxing and insurance in the continental U.S. is $100 per unit. Payment instructions are on the web page above, but PayPal is preferred. GL and DX!

Re: [Elecraft] RadioSport Headset - Which Mic Element
I've been using one of the RS-60CF headsets for several months. I got the electret microphone element, mainly because I've got an old Shure 444D desk mic I sometimes use, and I didn't want to fool with the radically different output level from the Heil dynamics. I'm by no means a dedicated phone operator, but the Radiosport mic has worked well in getting me heard through the sometimes raucous W1AW/* pileups and in a few contest sessions. Prior to getting the Radiosport headset I had been using a CM-500. It worked OK and I didn't need to change any level settings or EQ when I replaced it with the Radiosport mic. The Yamaha is certainly a good value for the money, but it doesn't come even close to the Radiosport set in terms of build quality, comfort and outside sound attenuation. I've found the RS-60CF (and the headphones only RS-20 variant) to be by far the most comfortable headset I've ever used. It's the only one that I've been able to use for the full 24 hours of Sweepstakes CW with essentially no discomfort. I know K9YC finds it uncomfortable, but as far as I know he's the only person I know of reporting this. YMMV. If you're concerned about whether you'll find it uncomfortable, perhaps you should see if you can find someone who has one he'll let you try out. You certainly should get great results with the electret mic feeding a K3. I don't think you'll be disappointed with the RS-60CF in any way. 73...

Re: [Elecraft] Computer won't connect with kx3
Correction Bob, The KX3 is capable of up to 38400 baud rate. Check the KX3 RS232 menu parameter. Yes, it defaults to 4800, but for firmware downloads, it is automatically set to 38400. Set it to whatever your control application is using. 73, Don W3FPR On 3/18/2014 9:51 PM, Bob N3MNT wrote: Check the baudrate. The KX3 used a lower baud rate.

[Elecraft] P3 marker B transmit freq.
Reading the P3 screen I see a station transmitting. I use Marker A (Green) to pin me on that desired station as soon as I tap the knob to QSY me to a desired signal. I listen to the station and they say UP so I know to hold in the MKR button to activate B ((Magenta) I see where the last transmission is and I place the Magenta marker at that location and tap: The Sub Rx goes to that frequency where the DX was last listening but sub is not engaged, it just sits on that frequency and does nothing with it. Problem is that if I don't then reach over and manually hold the split button on the K3 itself to have the K3 transmit on the DX listening frequency, I'll still keep transmitting on the DX transmit frequency because the K3 will not have gone split; its as if the procedure is halted half way and it shouldn't function this way, its not intuitive. If I'm going to the effort to engage Marker B to QSY its because I want to transmit on the Marker B frequency. What do I have to the do differently to force the K3 go split to transmit on the B freq when I tap on MKR B? Thanks, Gary KA1J --- This email is free from viruses and malware because avast!
