Re: [Elecraft] KX3 External Transverter and ATU TUNE disable option suggestion
Hi Don, Thanks for that. I was not referring specifically to the Elecraft XV series of transverters, as I have plans to rebuild my home built transverter for 144 MHz. So this was a general comment for those who want to use external transverters with their KX3, as I imagine quite a few may do given the high performance of the radio in such a small package. Some thought had gone in to supporting transverters by Elecraft with XV offset and XV H power limit and other very useful parameters that can be set, however having to use a large drive power of 4 watts and then attenuate it to a few mW for the transverter mixer is against the QRP principles, and for high duty cycle modes like JT65 is a non starter given the undersized heatsink on the KX3. One small change in the KX3 firmware to automatically put the ATU mode into BYPASS MODE when an XV is selected would solve this potential problem elegantly. Pretty please! 73 David Anderson GM4JJJ On 5 Jan 2014, at 03:55, Don Wilhelm w3...@embarqmail.com wrote: Dave, If you are referring to he Elecraft XV series transverters, then I suggest that you set up the transverter to use 4 watts input.

I can set the maximum power when using a transverter using the XV H in the KX3 menu, this is very useful, however I believe that the ATU TUNE button will still try and tune at approx 3 watts even though I set a lower maximum power of say 0.1 watts in XV H. I thought perhaps that when an XV was selected in the BAND that the ATU TUNE would be disabled, or the ATU always put in BYPASS mode but it is not. I know I can put the ATU in bypass mode, but I am bound to forget one day, and accidentally press ATU TUNE and cause damage to my transverter. I guess I have a feature request, make sure that ATU TUNE button does not transmit when a XV is selected (ATU in bypass mode) , it would also be nice if the ATU mode was band specific. __ 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] KX3 External Transverter and ATU TUNE disable optionsuggestion

Re: [Elecraft] K3 AFSK RTTY problem
Hi Ron and the group I hope you got your equipment to work on RTTY yesterday but if you didn't I have been there and done that several times. I didn't see anyone else respond so I will share some of my experiences. The first thing on all Windows systems newer than XP, Right click SPEAKERS than select playback devices, then communications and make sure to check DO NOTHING This turns off the AVC functions that are used by SKYPE and other similar programs. This may be causing your variations in level to the ALC. AFSK and FSKD use lower SSB on the Elecraft rigs while PSKD and DATA A use upper SSB. Your software must be set to match. My software was designed for other rigs and I must use INVERTED for AFSK or FSKD to make it work. Another variation I have seen to match some other rigs is TX INVERTED only. You should try the TEST position to see if you have the same ALC problem with no RF. It is possible to get RF feedback and or hum if there is a cable problem. I have also seen software do you a favor by switching to USB or RTTY after you have set up your transceiver. Needless to say this can cause unexplained problems until I can figure out what happened. I used FSKD in the contest yesterday to transmit and MixW to receive along with the N3FJP logging program. I used the following commands for F1 and F2. F1 kyw W0CZ W0CZ ;rx; F2 kyw 599 ND ND ;rx; . I also did some other F keys as desired. The rx; forces the transmitter to shut down right away after the message. I used the CATCMD function in the MixW macros but I think other software might have a similar method. If I use the K3 or KX3 utility than I use the COMMAND TESTER tab as the TERMINAL tab filters out all the commands. The MixW, MTTY and other programs often demodulate better than the utility for receiviing. I worked 161 RTTY contacts in the contest yesterday, all hunt and pounce using FSKD, in about 7 hours using 10, 15, 20, 40, and 80 meters. The antenna was my Hy-Gain Hy-Tower with radials. The station was the KX3 and the KXPA100-AT at 100 watts. Someone remarked yesterday that they had a new KX3 KXPA 100 station and they missed the P3 from the K3. I had the same problem and now use the iMic USB sound card from the I/Q jack on the KX3 and ROCKY software to give me a panadaptor display. It is not as nice as the P3 but it sure does work well for finding a contact either in a contest or for rag chewing. One final comment the KXPA100 has done everything I have tried so far. One caution though is PSK31 needs to be run at 50 watts or less because on that mode linearity becomes extremely important. If I operated in the RUN mode instead of HUNT and POUNCE it would also be important to cut my power back to 50 watts or less to prevent overheating the amplifier or the KX3. I hope these comments and suggestions are helpful. 73 and happy hamming in 2014 Ken W0CZ w...@i29.net Sent from my iPad On Jan 4, 2014, at 2:42 PM, Ron W3ZV w...@verizon.net wrote: I am trying to operate AFSK on 15m in the ARRL RU contest.

Re: [Elecraft] KX3 External Transverter and ATU TUNE disable optionsuggestion
David, I have a further thought about the difficulties of using the KX3 with an external transverter, if we reduce the maximum power output for the XVTR by using the XV PWR H setting to say a very low value (say the lowest which is 0.1 Watt), then is there a danger that the relative transmitted wideband amplifier noise will be higher than if we kept the power at say 4 Watts and then used a big attenuator on the input of the TX port on the transverter? All my previous experience with transverters have been with radios that had dedicated low power transverter RF out ports. Even then there were problems with thermal power drift, excessive drive levels due to lack of the normal ALC that radio normally depended on when using it on HF etc. I presume that there is no way to easily bypass the PA and driver stages within the KX3 to get lower drive power without reducing the TX gain. I have been looking at the KX3 schematics trying to work out where the as yet unreleased KX3 internal 2m transverter gets it drive from and at what level that is. Perhaps Elecraft may give us some clues or guidance. What would be neat, but it don't suppose we can expect Elecraft to do it, would be a board that would replace the planned internal 2m transverter, and would just act as a lower power transverter output from before the PA stages, on an SMA connector where the 2m antenna socket will be, with the main antenna BNC as a receive only port, (though that could be dangerous), perhaps a low power TX/RX on the SMA would be best. 73 David Anderson GM4JJJ On 5 Jan 2014, at 11:06, Dave d...@g0dja.co.uk wrote: I'll second Davids request.

Re: [Elecraft] KX3 External Transverter and ATU TUNE disable optionsuggestion
David, I don't know about the power control characteristics of the KX3 yet, but with the K2 without the K60XV option), more steady power control is achieved in the 2 to 10 watt range as compared to lower power levels. It all has to do with resolution - the power is set in 0.1 watt increments, and an uncertainty of 1 count can double or halve the power level at very low values, but that same uncertainty is much less at 2 watts and even less at 4 watts. For JT65 and other long transmission full duty cycle periods, the heat dissipation must be considered if you want to prolong the life of the finals - so use 2 or 3 watts. 73, Don W3FPR On 1/5/2014 2:42 PM, David Anderson wrote: David, I have a further thought about the difficulties of using the KX3 with an external transverter, if we reduce the maximum power output for the XVTR by using the XV PWR H setting to say a very low value (say the lowest which is 0.1 Watt), then is there a danger that the relative transmitted wideband amplifier noise will be higher than if we kept the power at say 4 Watts and then used a big attenuator on the input of the TX port on the transverter?

Hi everyone from cold, snowy Michigan. Yesterday, my K3 suddenly decided to have erratic receive audio. If I have the audio at the 9 o'clock position and start to turn it counter-clockwise to lessen the audio, the audio goes to half volume. I then brought up HRD and I can watch it on the software do the same thing. One thing...my external speaker was partly out of the K3 yesterday and I pushed it back in without turning the rig off. Had U1 blown, I would think I would have no audio Am I sending the DSP board in for repair? Thoughts?

Re: [Elecraft] Ham Radio Deluxe and KX3 Radio
AH, it's coming back to me! Many years ago Simon added the code so that you could use the Kenwood CAT code to key the radio. I've also seen the serial port thing done, but that needs either a second COM port or a special cable to be made up so that the keying to the CW jack is in the same socket as the COM port connection. Does the KX3 have the same commands for keying the CW circuits via the CAT interface like some Kenwood radios do?

[Elecraft] K3 - AFSK RTTY
What would a contest be if everything always worked like it did the last time in the contest. I use a minimalist RTTY setup: 2 stereo cables from LINE IN/OUT to LINE OUT/IN AFSK-A with PTT from VOX N1MM with one instance of MMTTY Basically, it worked fine, made over 700 Q's. At the urging of the club, I decided on the new SO Unlimited [i.e. assisted], and that worked OK too except: Every time I clicked on a band map spot, the radio went to FSK-D, and of course wouldn't key. I had the couple of usual N1MM lockouts and re-starting N1MM also caused this change to FSK-D. I'm running 4.58 FW, haven't loaded new in a long time, and N1MM is running 13.10.2, also haven't updated that in quite awhile, both have been working very well. I don't think this is a K3 problem, but wanted to check if anyone else using the minimalist configuration has seen this. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org Go SF! __ 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, Writelog] AF Level Reverting to 0 upon Context Switch
[Sorry for the cross-post; this is a matter involving both the K3 and Writelog.] During this weekend's RTTY Roundup, operating SO2V, I had a strange problem *sometimes* when changing TX focus via Writelog. I would be listening to both main and sub-receivers with TX focus on Main. If I toggled TX focus between Main and Sub, AF gain on the non-focus receiver would drop to zero. Touching the AF control ever so slightly would restore audio. It didn't matter whether I toggled focus by clicking a call in the other decoder window, clicking an Entry window field or using the EntryKbdXmitFocusDown function via a Keyboard Shortcut. Line Out audio to the decoders did not drop out. The problem persisted for several hours but eventually went away and both channels of audio stayed live through focus toggle events for the rest of Saturday. But Sunday morning when I fired up again, the problem returned. It did not seem to be a per-band issue as I saw the problem exist and go away on the same band(s). When it was mis-behaving, it did so on all bands that I checked and likewise when it was behaving. I believe I had Writelog Radio Menu | Headphones Normal and Headphones Latch set at all times. Writelog version 11.17E and K3 MCU version 4.77. Although this seems at first glance to be an obvious Writelog matter, it prompted *deja vu* feelings because a similar phenomenon (a bogus AF gain value) shows up when cycling a K3 Remote connection and has been attributed to a bug in K3 firmware, not yet fixed. Also, Writelog has dedicated K3 code to support SO2V using the two receivers and the K3 SPLIT function. That code is exercised whenever you toggle Writelog TX focus between Main and Sub-receivers. Any ideas?

Re: [Elecraft] K3 - AFSK RTTY
Here is one thing that will cause a similar problem: If you program a memory while DATA MD is X, then every time you recall that memory you will be put back into X, regardless of the DATA MD setting prior to the memory recall.

Re: [Elecraft] K3 - AFSK RTTY
In N1MM - Config - Configure Ports, Mode Control, Audi, Other - Mode Control ... make sure you have set the RTTY mode to *AFSK* and not *RTTY* if you are using AFSK. For more information read the very fine N1MM Logger on-line documentation. 73, ...

[Elecraft] Elecraft AF1 audio filter
Hello Elecrafters, Is this filter also useful in SSB in terms of giving more listening comfort? I like the selectivity of my K3 but still feel the audio of K3 in SSB is fairly harsh. Hence, I would wonder whether the elecraft AF1 filter will give any comfort to my ears. I do not know whether I am luck because I can still hear up to 14KHz. I also read some reviews about Idiompress SCAF-1 audio filter. However, apart from customer services, my limited technical knowledge cannot let me distinguish which filters will suit me better. Any advice from the elecrafters will be appreciated. 73 Johnny VR2XMC __ 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] KX3, Yamaha CM500 headphones and PTT switch
Hi folks, Newbie Dave with a KX3 and a brand new pair of Yamaha CM-500 headphones. I need a PTT switch. I’d like to build one. Is it as easy as wiring a momentary PTT, using the ACC2 port, the ACC2 I/O ON menu settings and a 1/8” mini jack? Read both the Elecraft manual and the Fred Cady book, still a little confused.

Re: [Elecraft] KX3, Yamaha CM500 headphones and PTT switch
Dave, The ACC2 will provide KEYOUT (for keying an amplifier, etc). You need KEYIN (or PTT). The PTT input is available on the mic jack. I made a special adapter for the CM500 using a 3 circuit 3.5mm jack. The tip and shell connect to the CM500 mic, and the ring and shell connect to a pushbutton switch that I use for PTT. It works very well. 73, Don W3FPR On 1/5/2014 11:15 PM, Esquer Dave wrote: Hi folks, Newbie Dave with a KX3 and a brand new pair of Yamaha CM-500 headphones. I need a PTT switch.

Re: [Elecraft] K3 AFSK RTTY problem
Yes, what you describes sounds like what happened to me when I switched to 80 meters. I did have to click the 'reverse' button on Fldigi to receive properly. Then when I tried to work stations, I got a lot of 'AGN.' I noticed the bargraph displays on the W2 watt meter kept flashing. I finally checked the DATA MD button and it was on 'AFSK A' instead of 'DATA A.' After changing it back to 'DATA A' and unchecking the 'reverse' button in Fldigi, I had no more problems.

I have 2 contacts in the last 2 hours. I am by no means a big gun, but I am usually better than this. Lineup is K3-KPA500-KAT-500. No problems on receive. Drive is set to produce about 350 watts from the KPA-500. SWR is below 1.5. As far as I can tell, baud rate, and shift are okay. I don’t think I am reversed. I know my signal is getting out, because I get a lot of AGN AGN. What disturbs me is that my ALC indication is rapidly jumping between 2 to 5 bars. This is not the 4 solid and 5 flickering. Power out on the KPA500 jumps between 300 and 400 watts. If anyone has a suggestion to get me back in the fray, I would be most grateful.

Re: [Elecraft] KX3 / K3 Antenna Sharing
One potential problem with the MFJ 4-way switch: It shorts the unselected positions to ground. If you are using it to switch between radios, transmitting on an unselected radio results in transmitting into a short circuit. I use it, but I try to be _very_ careful.

[Elecraft] Current use K3/10 vs. K3/100
Remembering the thread about how much current a K3/100 used when powered off, I decided to run a test as I installed the KPA3 in K3 #6299. The table below lists power use before (K3/10) and after (K3/100) 100w amp was installed. A monospaced font will help legibility. Test conditions: Direct connection to a 12v battery. RF and AF gain at zero. CW mode. No RS-232 connection. P3 power unplugged. IF out disconnected. MFJ dummy load. Tuned to 14.0475. Fluke 87 meter for current. Internal K3 meter for voltage. Straight key held down until current reading stabilized (c10 seconds.) K3/10K3/100 Measurement 0.1microA N/A V 4.1mA N/A V Power off idle current 873mA 12.1V 969mA 12.1V Receive 2.57A 10.8V 2.87A 11.0V Transmit 5W 3.19A 10.4V 3.53A 10.6V Transmit 10W The K3/100 uses 11% more power on receive, 12% more power on QRP transmit, and 11% more power on ten watt transmit. It may be worth removing the 100w amp for QRP battery field day like operations. Note that the PA temperature calibration changed the value by 3 degrees C. (This time I put a brewing thermometer next to the radio to act as the standard temperature. The last time I think I used the wall thermometer.) The MacIntosh K3 Utility did the Wattmeter calibration. As far as I know, these were the only changes to the radio's settings.
