[Elecraft] Serial Number 133
Last night at 11.50 my youngest daughter left for England and the family was sad, but .. 29 minutes later my new baby arrived in Perth !! so all was joyous. It was ordered in the early hours of 29th April and was delivered approx 8 months and 23 days later, a perfect gestation period. I picked it up this morniong and can report father and bub doing well getting to know each other ! Serial number is 133 and its a fully assembled, 100watt , complete with ATU bouncing bundle of health. Just need to get the settings right on the mic and will be on air tonight. It was supposed to be a birthday present in July but turned out to be a great Xmas pressie instead. Thanks to Lisa for her patience with my persistant enquiries and to the Elecraft team for such a fine radio... and isnt the receiver quiet !! 73 from Perth Western Australia and a very happy Xmas to all.

[Elecraft] External automatic antenna tuner
Gentlemen: I don't recall any questions (or answers) about having the K3 initiate an external antenna tuner, like the LDG RT-11 or perhaps one of the Icom or SGC external tuners. Did I miss this in the myriad of postings? I don't see it on the Yahoo forum or the FAQ. So the questions are: will the K3 be able to use the tune button to initiate an external antenna tuner? If so, what are the particular pins on the accessory jack to supply this tune button-initiated action? Can this occur on one coax output while still using (or not using) the internal tuner on another? Can it use an external tuner if the internal one is not installed? Will the K3 VFO (or it's memories) remember that tuner (internal or external) and antenna connector output the next time it's chosen?

[Elecraft] K2 K60XV IF Selection Option Question
I'm using my K2 with a recieve converter for the 600m band, currently interfaced via the receive antenna port. I recently installed the K60XV accessory to my K2 in preparation for use of the K2 as the IF on both transmit and receive on 600m. The problem: I discovered the firmware offers IF band selection down to 7 MHz. My converter uses a 3.5 MHz IF, a real advantage for image rejection with the RF input at 505 to 508 kHz. Can anyone on the reflector describe what may be involved with changing the selections available with the K60XV? Does it involve a firmware change or is there another work-around? If a firmware change is needed, how do I go about doing that? Any help or advice is much appreciated. I plan to use the K2 to operate digital modes under the 600m experimental license, WD2XSH/12. 73 Mike AI8Z WD2XSH/12 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Lousy Tx audio reports using K2
-Original Message- ...A previous message on this list mentioned that if you key the transmitter in CAL FIL mode, at least for an SSB FL1 filter, the signal is looped back to the receive side, through the filter. That could allow you a way to adjust the filter settings while listening to your own voice to see for yourself if it sounds bassy. -- I didn't know about that. When I adjusted my K2, I used a Drake 2B receiver to receive my own transmitted signal. I fed the audio from the Drake into my PC through a good sound card. I then transmitted with the K2 into a dummy load while I listened on the 2B. The recording showed me exactly what another person would have heard and I was able to fine tune my filter adjustment for my voice mic. I then put the mic away and haven't used SSB since :-).

[Elecraft] Re: OT - K2 Keyer problems
Kevin, Cold temperatures can aggravate and reveal marginal solder connections and socket/pin problems. I would recommend that you re-check all the soldering on the Control Board and re-seat the microprocessor in its socket to see if that helps. I doubt if you will find any device failures at the temperatures you are encountering - if the temperatures are below freezing, then you may be having marginal devices fail to work properly, but at 40 deg F, I doubt if any devices will fail - particularly those that read the control settings. Since you report that the speed changes are actually displayed, that says that the microprocessor *thinks* the pot setting has changed. There is a possibility that the speed pot itself is experiencing a failure at low temperatures and a pot replacement is in order. If you have ever used a control lube on your speed pot, then there could be a coating inside the pot element that is temperature sensitive, or such a lube coating may be something residual from the manufacturing process. Those are the only possible causes that I can think of at the moment. 73, Don W3FPR Kevin Rock wrote: Recently I had my K2 (#2511) upgraded with the A to B mod kits. I have had some odd experiences with it since then. When I get up each morning I need to stoke the fire to warm the house up. Sometimes the morning temperature is in the high 40s (F). Normally it is in the low 50s range. Not long after breakfast, both mine and Sam's, I am on the air working into Oklahoma. The shack temperature today was 55 when I started. My keyer was set at 23 wpm but the speed kept jumping all over the place. The display would show the new speed but only after I had flubbed a few characters due to the speed change. It would drop to 19 or jump to 28 wpm randomly. By the end of the contact (60 minutes) the shack temperature had risen to 58 and the variations had lessened somewhat but they were still occurring. Do you, or anyone else, know what may cause these random speed variations? Is it the new firmware, the temperature, or some random thing? 2.04P 1.09 is the reading at start up to give you some idea of the firmware version. Before the upgrade it would jump very rarely. Now it jumps more often. However, due to the change in seasons the rig is going through larger temperature cycles than it had been. I am nowhere near the wood stove so it does get pretty chilly back here. Once I take down my Christmas tree I'll move back up into the front room but for now I need some way to limit the speed cycling. Should I turn the rig on an hour before I get on the air to help it stabilize? Cover it with a tea cozy? Put a space heater under it? Take down the tree and move near the wood stove?

Re: [Elecraft] K3's Transmit Inihibit function (TX INH)
Wayne wrote: Hi all, I've just added the TX INH function and its associated menu entry to the K3. Just in case you have no clue what this is: it provides a way for an external station controller to determine which of two or more transceivers can have access to resources such as an amplifier. It's typically used in multi-op contest situations. By popular demand, the TX inhibit level can be *either* active-low or active-high. Thus the TX INH menu entry has three settings: OFF (no TX inhibit) LO=INH (a logic 0 inhibits transmit) HI=INH (a logic 1, 5 V, inhibits transmit) I'm testing this feature right now, and it should be in the next production firmware release. Thank you, Wayne, that's excellent. One final detail: if any external device is using the TX INH input as a Clear To Send handshaking signal, then hopefully the CTS signal will be interpreted as Clear To Send NOW, and the K3 will respond with the absolute minimum of internal delays. (Sorry to beat this horse again, but I'm asking now because it affects a project that is already in the detailed planning stage. When the K3 arrives, I'll measure the TX/RX delays myself, of course.) -- 73 from Ian GM3SEK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Lousy Tx audio reports using K2
Eddy, It is important where you set the audio passband. Normally, there is no lack of high frequency response with the 2.6kHz bandpass. Using Spectrogram to set the SSB filters, I normally recommend that you set markers at 300 Hz and the filter width plus 200 Hz - or in your case, 2800 Hz. Center the FL1 (OP1) passband between those markers and try it out. With most voices and microphones, those settings are correct, and wil work quite well for receive as well. For FL2, I use the variable filter and set it 300 Hz less than FL1 - it is important to measure the actual width with Spectrogram since at wide setting the numbers shown by the K2 are usually incorrect. Set the low frequency corner of all the SSB filter passbands at 300 Hz to maintain intelligibility as the filters are narrowed. If you are 'netting' with other hams at a specific frequency, you should check your dial calibration - if you are not tuned to the actual frequency of the other hams (because your dial calibration is off), it could be that your audio is OK, but you are placing your transmit frequency a bit high or low. The K2 Dial Calibration article on my website http://w3fpr.qrpradio.com can give you the procedure for obtaining good dial calibration. If filter alignment as I have outlined does not solve your problem, you may have a microphone that is lacking in response at the higher audio frequencies, but the MH2 usually has a bit of boost for the highs - you might want to see if one of the locals near you has an MH2 that you can compare with. 73, Don W3FPR Eddy Avila wrote: Happy Holidays All, Getting lousy SSB tx audio reports on K2, SN 3345.

We could then use one of the K3's spare output lines (say DIGOUT1) to switch the relay under firmware control, per-band. There would be one wire running from the AUX I/O connector to the BL3, and you'd need to power the relay from the K3's switched 12 VDC accessory output.

[Elecraft] Re: 12 VDC Output
Joe, We just measured the voltage at the 12V ACC output on three K3s. DC into the K3 APP connector was 13.80 in all cases (measured at the APP connector, K3 powered ON, in receive mode).

Re: [Elecraft] DSPPerformance of K3 vs 756 Pro III
I have to second this. The K3 DSP is what DSP should be; the filters are very sharp, yet even at the lower bandwidths (down to 50 Hz) they don't ring excessively. It really shines with the noise reduction function (NR). Firstly, the NR level is adjustable so you can tune it for the minimum necessary for the situation, but even at its most aggressive the ONLY artifact I have noticed is a slightly hollow bottom of the well sound with NO degradation of the information be it ssb or cw. Lyle has out-done himself on this!

W4sc wrote: Adding TX Inhibit was a great feature to have. Looking at the details though it seems this function is NOT available when the transverter interface is enabled. Hi Ben, As I'll be explaining in the next edition of the owner's manual, the XVTR ON signal is just a DC voltage that's present when the K3 is turned on. It doesn't turn on only when you're on transverter bands, and really should be called something else (like Hey, I'm on!). It behaves the same as the related pin on the K2's 9-pin connector. If you need to use this pin on the K3 for TX INH, instead, you can still get a functionally equivalent XVTR ON signal by using the K3's switched 12 VDC (at the accessory output RCA jack). Just connect it to pin 9 of the transverter control port. You can use a series resistor, say 1 K, since very little current is required at the transverter to turn its MOSFET power switch on. I'll be including full details for the K3 to transverter interface in the manual. Sorry for the delay. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Lousy Tx audio reports using K2
Eddy, Since you mentioned a lack of highs, I doubt that the low-frequency response mod will help much, but you certainly can try. What is more important is the place the low frequency corner of the FL1 passband close to 300 Hz. If you do that, when you tune an SSB signal so it sounds right in your K2, you will transmit on his frequency (because you tuned his voice to fall into the 300 to 2800 kHz range where it sounds best to most ears). If you OP1 filter is set 100 Hz high or low, then you can still receive by skewing the frequency (you really will not know you are doing that, but it happens that way), but then when you transmit, you do not sound right to the person on the receiving end. When I set up a K2 that is in here for repair, I listen not only to the received signal, but I listen to a transmitted signal on another receiver. I have found that the 300 Hz filter corner (-3 to 6 dB point) is the one most important factor in making transmit and receive line up properly. 73, Don W3FPR k6sdw wrote: Good stuff Don!

Re: [Elecraft] External automatic antenna tuner
Forrest I also requested this a few months ago. The K3 doesn't support external tuners very well. Not only can it not trigger an external tuner or be triggered to tune mode by one, but it doesn't drop to a safe power level on tune like the K2 or other rigs. No promise of delivery on this. BTW - the KRC2 is no help with this either So the questions are: will the K3 be able to use the tune button to initiate an external antenna tuner? If so, what are the particular pins on the accessory jack to supply this tune button-initiated action?

Hi Bob, Both a drop in TUNE power level and an external ATU trigger signal are on my firmware list. I'm trying really hard to do everything at once; someone recommended cloning. Anyone having expertise in this area should contact me directly. Do I get a per-unit discount if you can clone me twice?

[Elecraft] New K3 Firmware Update (MCU rev 1.53, DSP rev 1.47)
Hi all, We've just posted updated firmware on our FTP site. Be sure to install the latest version of our firmware downloader (K3 Utility), revision date 12-9-07, before you do the upgrade. Here are the changes in this revision (within K3 Utility, use Help/K3 Firmware Release Notes): MCU 1.53 and DSP 1.47, 12-19-07 * TX INH menu entry added (Transmit Inhibit). This can be used in multi-transmitter stations to control access to station resources such as amplifiers or antennas. Default is OFF (no inhibit function; pin 7 is then an output used as XVTRON). If set to LO=INH or HI=INH, operator must supply an external TTL or open-collector/open-drain driver (a pullup to 5V is required in this case).When the rig is inhibited, the TX LCD icon flashes slowly (same as TX TEST mode). Using transmit-start switches (XMIT, TUNE, ATU, M1-M4) results in a brief TX INH message on VFO B. The key, keyer paddle, /PTT, and TX via PC commands are all nonfunctional. * S-meter linearization above S9 has been improved. (Much greater accuracy is possible via an automated calibration algorithm. This is still in development.) * LINE IN function now behaves correctly on power-up. * Receive filter controls (SHIFT, WIDTH, etc.) and switches (XFIL, etc.) are locked out during transmit. * TRANSVERTER SUPPORT: 1. The XVn OFS menu entry is functional (+/- 9.99 kHz offset, per transverter band). 2. Elecraft XV-series transverter address is being sent via the auxBus. 3. M-V and V-M now work with transverter bands. 4. Direct Freq Entry works between HF and transverter bands. Examples of direct freq entry on transverter bands: 144, 144.2, 144.23, 144.235. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Lousy Tx audio reports using K2
Don... When you cite the -3 to 6dB point, do you mean to say -3 to -6dB? That is to say, that the corner of the filter response, presumably falling at the -3 to -6dB point should be positioned at 300cps. Is this a correct interpretation of your recommendation? Thanks. ...robert At 12/21/2007 16:51, Don Wilhelm wrote: Eddy, Since you mentioned a lack of highs, I doubt that the low-frequency response mod will help much, but you certainly can try. What is more important is the place the low frequency corner of the FL1 passband close to 300 Hz. If you do that, when you tune an SSB signal so it sounds right in your K2, you will transmit on his frequency (because you tuned his voice to fall into the 300 to 2800 kHz range where it sounds best to most ears). If you OP1 filter is set 100 Hz high or low, then you can still receive by skewing the frequency (you really will not know you are doing that, but it happens that way), but then when you transmit, you do not sound right to the person on the receiving end. When I set up a K2 that is in here for repair, I listen not only to the received signal, but I listen to a transmitted signal on another receiver. I have found that the 300 Hz filter corner (-3 to 6 dB point) is the one most important factor in making transmit and receive line up properly. 73, Don W3FPR k6sdw wrote: Good stuff Don! I'm concerning doing the G3RXQ mod to the KSB2 and see if that helps with the low-freq response. 73... Don Wilhelm wrote: Eddy, It is important where you set the audio passband. Normally, there is no lack of high frequency response with the 2.6kHz bandpass. Using Spectrogram to set the SSB filters, I normally recommend that you set markers at 300 Hz and the filter width plus 200 Hz - or in your case, 2800 Hz. Center the FL1 (OP1) passband between those markers and try it out. With most voices and microphones, those settings are correct, and wil work quite well for receive as well. For FL2, I use the variable filter and set it 300 Hz less than FL1 - it is important to measure the actual width with Spectrogram since at wide setting the numbers shown by the K2 are usually incorrect. Set the low frequency corner of all the SSB filter passbands at 300 Hz to maintain intelligibility as the filters are narrowed. If you are 'netting' with other hams at a specific frequency, you should check your dial calibration - if you are not tuned to the actual frequency of the other hams (because your dial calibration is off), it could be that your audio is OK, but you are placing your transmit frequency a bit high or low. The K2 Dial Calibration article on my website http://w3fpr.qrpradio.com can give you the procedure for obtaining good dial calibration. If filter alignment as I have outlined does not solve your problem, you may have a microphone that is lacking in response at the higher audio frequencies, but the MH2 usually has a bit of boost for the highs - you might want to see if one of the locals near you has an MH2 that you can compare with. 73, Don W3FPR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3/100 #137 has arrived in Toronto Canada
Factory assembled K3/100 was ordered 1 May 2007. Received 21 Dec in Toronto Canada. It was shipped 19 Dec by UPS Worldwide Express and was held up in customs for a few hours and thus missed its scheduled delivery (20 Dec). It seems that this customs officer had assumed that VE3QF was a business and that there should be some duty charged. I explained to UPS (the broker) that it was a shipment to a private person and the contents consisted of Amateur radio equipment. I also quoted a customs tariff number (8527.39.10.00). That may be an old number but in the end the K3 was cleared. I did not see any reference to Amateur radio equipment or any customs declaration form on the box. This could have been removed by customs but usually a copy is kept with the shipment. I unfortunately don't have much experience with customs clearance. I would suggest that the call-sign be put after the name and not on a separate line. For Canada the key words are Amateur radio equipment. This means duty free. The radio was double boxed and arrived in perfect condition. First impression is very positive and definitely worth the wait. I had good reports on our 10M net. My thanks to the Elecraft team. Merry Christmas and a successful New Year. 73 Tony Fegan VE3QF ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
