[Elecraft] K3 Beta firmware rev. 2.82
In a recent message, wayne burdick n...@elecraft.com wrote ... K3 beta-test firmware revision 2.82 (with DSP rev 2.00) is now available. See release notes below. Many thanks for the latest firmware - all installed successfully and apparently working okay. In a future release, would it be possible for the Power Level RF indicator to show the mW power when using the K3 with the XV--- transverters? While accepting the limitations of the LCD display, it would be useful if the power meter read from 0 to 1.2mW. 73 -- David G4DMP Leeds, England, UK -- __ 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] Dynamic Mics on K3
Don Wilhelm ha scritto: Giulio, You did not say what microphones you were trying to use, only that they were 'dynamic'. Are you attempting to use Pro-Audio microphones? If so, check out the information provided by Jim Brown K9YC at http://haminterfacing.pdf/. Do your microphones have adequate output? Do they need Phantom Power? There can be many reasons you are not having success. How does the audio sound from the K3 monitor. You said you did the evaluation on 144 MHz, but what mode? If it is FM, then many have reported issues with 'thin audio' on FM, and Elecraft is currently working on improvement for that condition. How does the K3 sound with the microphones on SSB? Currently I'm using a Shure SM57 dynamic mic. The others are brandless or unknown. The mic doesn't need phantom power, but I agree with you that the output level of the microphone maybe is a little low. The tests I run were on SSB only, no FM or AM. The sound on the K3 monitor seems perfect (and that points the problem elsewhere, that is a test I didn't make until a minute ago). After a brief test on hf (listening on a K2) the audio seems fairly better than on 144 MHz. I've a feeling about the XV144 It seems that at a certain point in the IF path the signal become reduced in bandwidth, maybe the filters are a little off band 73 de Giulio IW3HVB __ 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] K3 Beta firmware rev. 2.80: Improvements to AFSK-A, DATA-A, SSB, AM, FM, DVR
hi Wayne, wayne burdick schrieb am 10 Feb 2009 um 15:00: * SSB/DATA-A/AFSK-A TRANSMIT POWER LEVEL: Power output in these modes now more closely tracks TUNE power. We recommend setting CONFIG:TXG VCE to 0.0 dB after loading this release, then adjusting only if necessary. * DATA MODE ALC METERING: ALC metering for DATA-A and AFSK-A modes has been adjusted to make the transmit audio level easier to adjust. As before, the recommended audio level for transmission is 4 to 5 bars. 3 bars will appear as soon the minimum required level for good S/N ratio has been reached. I tested the new firmware with my K3 + Ptc-2 TRX modem built inside the K3 and I think you have made a good improvement with the latest firmware 2.82. The output measured on my LP-100 meter is in a 5% range close to the power setting of the K3. I had to set the LINE IN GAIN higher than before, it is now at 20, before it was at 12. My output settings in the TRX-PTC modem are set to 1000mV for PSKA and 800 mV for FSKA. TXG VCE is set to 0.0dB This combination gives me the recommanded 4 bars of ALC. Throughput is good as far I can tell - I'll have to check this in the evening with better conditions to the RMS oe3xec which I can connect on 80m in distance of 280 nautical miles. thank you very much, that's what I like with you and the K3.

Re: [Elecraft] K3 Birdies
My K3, 10w Kit version haven't remarkable Birdies, but I am to order the second receiver unit KRX3. So my question is: is the new option responsible of more Birdies? thanks for any answer 73 I0cg Italy -- Message: 1 Date: Tue, 10 Feb 2009 09:09:35 -0800 From: wayne burdick n...@elecraft.com Subject: [Elecraft] K3 Birdies: firmware-based fix in progress To: Elecraft Reflector Elecraft@mailman.qth.net Message-ID: 59aa74da58ea67722f9def82c0e2a...@elecraft.com Content-Type: text/plain; charset=US-ASCII; format=flowed The K3 is a down-conversion superhet that uses high-level signal injection to achieve its excellent dynamic range. Short of adding many more pounds of shielding and elaborate cable dressing, there's no way to completely eliminate the few spurious signals that rise above the noise floor. These Fast-tuning birdies result from UHF harmonics of the signal sources that leak back into the main mixer. In some cases they combine and end up in either the I.F. or R.F./image range of the receiver. Typically, they involve 9th-order or higher harmonics of the VFO. That's what makes them fast: if you move the VFO 100 Hz, the pitch of the birdie will shift on the order of 1 to 2 kHz. While it is possible to attenuate some spurious responses by moving coax cables around, there is a firmware-based approach that we're working on. The general idea is to shift the 1st LO and BFO a small amount, simultaneously, when the VFO is tuned to specific frequencies. If the shift is small relative to the communications bandwidth in use, it will hardly be noticeable when the VFO is tuned over a mapped out spot in the tuning range. I have this new firmware nearly completed, and in early tests, it appears to work very well. Fast-tuning birdies that are mapped out pretty much disappear as the VFO is tuned over them. The upshot is that you can have your cake (outstanding dynamic range in a rig that weighs less than 10 pounds) and eat it, too (no annoying birdies). If you'd like to try a field-test version of K3 firmware that includes this new feature, please e-mail me directly. 73, Wayne N6KR --- http://www.elecraft.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

[Elecraft] K2/100 problem on 80 meters
From Don W3FPR But, if you have added the KPA100UPKT, I must ask if your upgrade kit included a new C31 capacitor of 0.22 uF value. Many KPA100UPKT kits did not include this capacitor until recently. If this situation fits your case, send an email to pa...@elecraft.com asking for a new capacitor... Sometime ago (around 2007), I ordered and received the KPA100UPKT upgrade kit for my K2/100 #5170, but never installed it. I will do it soon. After checking the (old) package and the manual page, I see that there are new parts in the instruction errata which I did not receive in 2007: 5 capacitors and a crystal... so will ask Elecraft for them before I start that upgrade.

[Elecraft] K3 to THP 1.5KFx connector
I researched the 5 pin DIN connector that is on the back of the THP 1.5KFx amp's Yaesu interface jack and have a part number. This will enable any K3 which has the pullup resistors for band data installed on the KIO3 through the ALC mod or factory cut in to output band data to the amp and have it follow band changes just like the K3 was a Yaesu transceiver. The SwitchCraft part number is: 12GM5M (presumably series 12GM, 5 pin, male) The Mouser part number is:502-12GM5M It is important to note that this is a male connector with 5 pins distributed around 240 degrees. The more common 5 pin DIN connectors have the 5 pins distributed around 180 degrees, these will NOT work. Wiring is straightforward from the DB15 connector to the 5 pin DIN. 4 signals plus ground. And ALC as a separate cable for those so inclined. www.zerobeat.net/mediawiki/index.php/K3_to_Tokyo_Hy-Power_HL_1.5KFX_amplifie r shows the wiring diagram; presumably a K3 with the pullup resistors installed internally does not need the external 5 volt source.

Re: [Elecraft] K2/100 problem on 80 meters
Pierre, Yes, there was an early version of the KPA100UPKT and only a few were shipped. You may not need all the added parts - they were added because some KPA100 owners had added mods to correct other problems, so the parts were added to allow any KPA100 to be restored to the standard parts. You will definitely need the new capacitor for C31, and you may need the new crystal. R4 should be changed to 100k if it has a different value New capacitors for C80 and C81 were included because some builders had changed them in an attempt to cure a low power situation on 20 and 17 meters. You should have new resistors to install at R19 and R20 - inductive resistors here were the real cause of the low power on 20 and 17 meters. If you had never changed C71 and C72 to reduce the click on unmute problem that some K2 owners experienced when the KDSP2 was installed, those capacitors will not be needed. 73, Don W3FPR Pierre wrote: From Don W3FPR But, if you have added the KPA100UPKT, I must ask if your upgrade kit included a new C31 capacitor of 0.22 uF value.

The EV 664 is the grandfather to the RE16 that I use, and is an excellent choice for ham radio. You should feed the 664 directly into the K3. Use the wiring in the Ham Interfacing link I just posted, and also the same TXEQ settings. With respect to wiring -- see page 47 of the tutorial, and note that pin numbers are shown for the Standard 3-pin XLR connector wiring used in pro audio. If your mic has a 4-pin XLR the wiring will be different. By the way -- the 4-pin XLR is NOT a Standard for audio anywhere in the world. You can find the mic wires by probing between the connector pins with an ohmmeter. The mic capsule (the two balanced wires) will measure as some low resistance value on the order of 50 ohms, AND you will hear a click if you put your ear close to the mic. I'm looking at the original data sheet for a 664. It has both high impedance and low impedance outputs. You want the LOW impedance output for the K3. For the connector that is built into the mic, pin 1 is shield, pin 3 and 4 are the balanced low impedance outputs. The 664 has some built-in equalization that boosts the highs an bit and rolls off the lows a bit. For that reason, you don't need quite as much TXEQ as for the RE16 that I'm using. For the 664, I would use about 3dB less cut at 50, 100, and 200 Hz, no EQ at 400 Hz, no boost at 2.4 kHz and about 5 dB boost at 3.2 kHz. 73, Jim Brown K9YC __ 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] Dynamic Mics on K3
With any pro mic, you should adjust the TX equalizer to reduce the level of the lowest audio bands and boost the level of the two highest bands. The TXEQ settings in my K3 are: Jim's settings look good for standard bandwidth SSB. For the K3's ESSB mode, I would rein-in on the EQ extremes, and try a cut at 200Hz. The 50-100Hz bands can be flat or even boosted slightly, depending on the response of the mic. At the high end, I would back off on the 3.2K setting to no more than +5-6 dB, again depending on the mic's response. Results will vary, but that's a good place to start with a dynamic mic. I'm not sure if anyone has measured the K3's TX ESSB distortion products between 50-100 Hz (sourced through the front panel mic connector), but backing off on TX output power and running a slightly elevated V+ may be the neighborly thing to do.

[Elecraft] Mic Audio Problems with K3 and DXD
This query goes to anyone out there who might be using a K3 with a TopTen DX Doubler. I recently got my new K3, and now have it and an FT1000MP connected to a DXD in a SO2R setup, using prefabricated cables purchased from TopTen, and a Heil Proset plus headset. All is well with the MP, which has worked fine with the DXD for several months. On the K3, ptt, key and earphones all work fine, but I'm having trouble with a strange rumbly, gravelly hash and feedback on transmit with the mic (also in test mode). The mic works fine when connected directly to the K3. It also works fine to the MP through the DX Doubler, but when I connect the mic to the DXD and then to the K3 via the cable I get hash and a rumbling windy sounding feedback, even with the monitor off. There is no hum on keydown when I do not speak. It's also clean when I whistle into the mic, but when I speak I get the hash and rumbling. I've confirmed its presence with on air testing. I've tried front and back mic connections on the K3. and both high and low mic gain settings on the menu. Bias is off. I've also tried adjusting TX EQ on the config menu. Again, it's perfect when connected directly to the radio, but bad when cabled through the DXD. I get identical hash on the K3 whether I'm connected to Radio 1 or Radio 2 connectors on the DXD . and the MP works fine on both. It would seem that the problem must be in the cable connecting DXD to K3, but the cable seems to check out OK. It has good continuity on all pins and all are isolated from one another except the common shield which is as it should be. I did note that the mic ground lead is not a shield, but just another wire inside the main cable? I added a shielded mic line with isolated shield to rule that out as a problem resulting in no change. Has anyone else experienced similar problems? If so, any suggestions?

[Elecraft] KAT3 auto select by high SWR?
I've been wondering if there is a setting I might have missed which tells the KAT3 to seek a better SWR as I change bands or go to different areas of a given band. I always have to tap the ATU-Tune button to have it adjust for a given location I am on, is there any setting I've missed to have the ATU automatically do this without my having to tell it to do so?

I agree with Paul that for ESSB, less equalization is appropriate. I would, however, still apply steep low cut at 50 Hz and 100 Hz to any pro mic, simply because there's no useful speech content in those bands, but most mics will produce popping and other breathe noise in that spectrum, and most shacks will have a lot of acoustic noise in that spectrum. All single-D mics (virtually all popular handheld vocal mics) suffer from proximity effect, so some low cut is also needed for the 200 Hz octave band with these mics. As to high frequency EQ -- this EQ compensates for the rolloff produced by the TX filter and the RX filter, so if you're transmitting through a wide filter, I would not use that EQ. That said, I consider ESSB to be quite wasteful of the limited spectrum available to hams. It's fine to use it when there's little activity on the bands, but those who are selfish enough to use it on a crowded band make me want to build and fire up an arc transmitter. 73, Jim Brown K9YC __ 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 configuration finalization plus diversity receive antenna question
Dear group, I'm just about ready to place my order for a K3 (hopefully by tomorrow.yay!) After some good discussions with list members, I think I've finally narrowed down my option choices: * K3/100 kit * KAT3 ATU * KBPF3 gen. cov. Module (1 unit, will be placed on SUB receiver) * KDVR3 Dig. Voice recorder * 500Hz 5 pole (2 units, one on each receiver) * 6KHz filter (1 unit, will be placed on main RF board for ESSB experimentation) * 13KHz FM filter (2 units, one on each receiver) * 40Hz filter matching for 2.7 and 500Hz filters * KRX3 sub receiver * KTCXO3-1 1ppm oscillator * KXV3 xverter interface * MH2 hand mic I'm mostly an SSB guy, but do play around with PSK31 and RTTY. I also like to listen to shortwave broadcast stations. The sub receiver will get the gen coverage module plus a 13, 2.7, and 500 filter. The 2.7 and 500 will be matched for diversity receive. The FM filter on the RF board will be used for 10m repeaters, while the FM filter on the sub will be used for broadcast reception. I don't know if anyone here has heard of the AOR LA-390 active loop RX antenna, but I'm thinking this might work well for my diversity experiments. I'm space limited, and this thing can be kept on my window ledge. http://universal-radio.com/catalog/sw_ant/2320.html I plan on using a Buddipole for my TX antenna connected to input 1 on the KAT3. The AOR loop antenna will be connected to the AUX RF BNC input. The loop antenna will also be used for SWL'ing. I'm assuming that the gen coverage module will function with the sub receiver using the AUX RF BNC input?

[Elecraft] Modulation on XV144 was: Dynamic mics on a K3
After a few good suggestions by Don, Jim and Fern I run a few more tests, coming at the conclusion that the problem was not the MIC, or its interfacing with the K3 or the radio itself. The audio on HF bands is simply perfect, with or without compression (and comp acts exactly as it should). But the problem on 144 MHz is still there, so the problem must be on the XV144. The Power supply is the same for both the radio and the xverter, tried switching and stabilized with no differences. I've no idea where to look.. Changing the drive power (I'm using the KXV3 module) does'nt produce any difference as well.

I'd hate to disassemble the sub receiver just to install a filter on the main board at a later date. 73, James KC2UEE __ 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] Modulation on XV144 was: Dynamic mics on a K3
Giulio, Unless the XV144 is operating in a non-linear region, it should not distort the SSB signal. Should be easy enough to check the linearity if you have a good power meter for 144 MHz. Go to CW and drive the transverter with 1/10 the normal power - it should have 1/10 the normal output - now increase the drive to 1/5 of normal and check again - continue until you have covered the entire power output range in increments. If the transverter output does not track the input level, check the XV144 PA bias adjustment. You might want to connect the KXV3 IF output to an indoor 10 meter antenna and listen to the 28 MHz output on another receiver with a short antenna (adjust to give an S-9 signal into that receiver). That will tell you if the 28 MHz KXV3 output is clean. 73, Don W3FPR Giulio Pico - IW3HVB wrote: After a few good suggestions by Don, Jim and Fern I run a few more tests, coming at the conclusion that the problem was not the MIC, or its interfacing with the K3 or the radio itself. The audio on HF bands is simply perfect, with or without compression (and comp acts exactly as it should). But the problem on 144 MHz is still there, so the problem must be on the XV144. The Power supply is the same for both the radio and the xverter, tried switching and stabilized with no differences. I've no idea where to look.. Changing the drive power (I'm using the KXV3 module) does'nt produce any difference as well.

Re: [Elecraft] Calibration of KXV3 module
This will not work. The HT antenna is almost guaranteed -not- to be 50 ohms, especially at the nominal 28 MHz output of the xv port. The only place this antenna will be even close to resonance is at its operating fequency (I'm assumung 144 or 432 MHz). And HT antennas are notoiously variable in their actual impedance, since it usually depends on the interaction with you body when you hold the HT. You need a 50 ohm resistive termination. 73, Eric _..._ -Original Message- From: Mark Bayern plcm...@gmail.com Date: Wednesday, Feb 11, 2009 1:49 pm Subject: Re: [Elecraft] Calibration of KXV3 module To: James Sarte kc2...@gmail.com CC: elecraft@mailman.qth.net elecraft@mailman.qth.net Will the stubby helical whip really be 50ohms at the freq out from the XVTR OUT jack?

Re: [Elecraft] 12v acc out
That means voltage is available at the 12V ACC socket when the K3 is 'switched on' - no relationship with transmit.

No K3 speak at all. 73, Don W3FPR greenacres...@aol.com wrote: New K3 #2626. Manual says 12v acc socket switched. That mean only on transmit or only when radio on you get 12v?

Re: [Elecraft] Calibration of KXV3 module
If you use a dummy load, you may wish to be certain it's okay for VHF. Some dummy loads which are primarily designed for HF frequencies become rather reactive on VHF. I think the length of the internal leads in the device had some inductance and/or capacitance to the mix and, therefore, below presented to the radio is no longer a pure resistance.

[Elecraft] K2-XV222 RFI Susceptibility Problems - a solution found
A couple of weeks ago I posted here regarding a problem whereby transmitting on my 6m rig cause my XV222 (connected to K2/K60XV) to key up. It appears that if any moderate amount of stray RF ends up on the tranmit IF line (probably due to imperfect shielding of the transverter rear panel jacks), this power is then detected by the power detector diode on the K60XV board, which then apparently triggers the K2 to switch the state of the 8R line. This then keys the transverter. No word yet from those in the know as to whether this firmware behaviour in the K2 is to be expected or not. Id be interested in hearing the results if anyone else wants to try injecting up to 1 mW of RF (HF or VHF...it shouldn't matter much) into the K2/K60XV XVTR OUT jack (while receiving) and checking to see what happens. I have found a solution which works at my home station. That is to put a filter in the transmit IF line which passes 28 MHz but does not pass 50 MHz. At present I have it mounted in an external box with a short coax cable to the XVTR OUT jack on the K2. I think it still needs a little tweaking to give a good match so that the K60XV will give full output in transmit, but the odd effects when I transmit on 6m have completely disappeared. I may still work on improving the XV222 shielding in case the problem is worse in my rover setup. 73, Steve VE3SMA __ Looking for the perfect gift?

Re: [Elecraft] K3 configuration finalization plus diversity receive antenna question
Hi Bruce, No, the 13KHz filter will be used for AM SW/MW/LW reception, not FM on the sub. The other FM filter on the main will only be used for 10m FM TX/RX. Here's an excerpt from a conversation I had with another fellow regarding the use of FM filters for AM broadcast reception: Just to make sure I understand you, the AM filter is only required if one desires to transmit in AM or use ESSB. Otherwise, AM reception like SW can still be piped through the 13KHz FM filter? Correct, I use the FM filter for listening to AM broadcast or SWL on a fairly regular basis. How does the audio of AM SW sound going through the FM filter? Bandwidth is obviously wider, so I'm assuming higher fidelity? Somewhat higher fidelity. The K3's DSP has a fairly sharp cutoff at 4200 Hz so you will never get more than that but the FM filter allows the full 4.5 KHz where the AM filter starts to roll off at 3 KHz but still has some audio response down the filter skirts. I hope that someday Elecraft will open up the audio in AM so we can hear 5.5 or 6 KHz which as good as it gets these days. Hope that helps to clarify. 73, James KC2UEE _ From: Bruce McLaughlin [mailto:bmcla...@bex.net] Sent: Wednesday, February 11, 2009 8:27 PM To: 'James Sarte' Subject: RE: [Elecraft] K3 configuration finalization plus diversity receive antenna question That sounds like a well-rounded package, although, I'm a bit confused by your plan to use the FM filter on the sub receiver for broadcast reception. The K-3 will not go to the FM broadcast band and I don't think you can get there using a transverter either. Also, the 13 kHz roofing filter, and the DSP are not really wide enough for broadcast FM. The 15 kHz deviation is such that I think you will have considerable distortion on a system designed for a maximum of 5 kHz deviation if it is recognizable at all. I could be mistaken about that, but you may want to check with others. I also wonder if you could save a bit of money by having only one 13 kHz filter installed on the main receiver. Assuming it will work for FM broadcast reception, unless you plan to listen to FM broadcasts for long periods of time, I would think using the main receiver for that purpose would probably be sufficient. It also could be used for FM transmission on the ham bands. As I am sure you know, you cannot transmit using the sub receiver. I have 2 K3s. The older unit has an FM filter installed in the main receiver. The newest unit has no FM receiver filter since my use of FM is likely to be very limited and certainly not at all until 10 meters begins to work again. But your plans may be different and you may have different needs.

Short of adding many more pounds of shielding and elaborate cable dressing, there's no way to completely eliminate the few spurious signals that rise above the noise floor. These Fast-tuning birdies result from UHF harmonics of the signal sources that leak back into the main mixer. In some cases they combine and end up in either the I.F. or R.F./image range of the receiver. Typically, they involve 9th-order or higher harmonics of the VFO. That's what makes them fast: if you move the VFO 100 Hz, the pitch of the birdie will shift on the order of 1 to 2 kHz. While it is possible to attenuate some spurious responses by moving coax cables around, there is a firmware-based approach that we're working on. The general idea is to shift the 1st LO and BFO a small amount, simultaneously, when the VFO is tuned to specific frequencies. If the shift is small relative to the communications bandwidth in use, it will hardly be noticeable when the VFO is tuned over a mapped out spot in the tuning range. I have this new firmware nearly completed, and in early tests, it appears to work very well. Fast-tuning birdies that are mapped out pretty much disappear as the VFO is tuned over them. The upshot is that you can have your cake (outstanding dynamic range in a rig that weighs less than 10 pounds) and eat it, too (no annoying birdies). If you'd like to try a field-test version of K3 firmware that includes this new feature, please e-mail me directly. 73, Wayne N6KR --- http://www.elecraft.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 Yahoo!香港提供網上安全攻略，教你如何防範黑客! 請前往 http://hk.promo.yahoo.com/security/ 了解更多!__ 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] Dynamic Mics on K3
Giulio, Your problem is easy to fix. I also use a Shure SM 57 on my K3. It is a professional microphone, and is Low Impedance. You need to use an in-line impedance matching transformer. I use a Shure A95UF with an adaptor cable I made myself. They are inexpensive and work very well. Companies like Shure, Audio Technica, Radio Shack, Sescom, and many others make them. Here is an example: http://www.coutant.org/matching/5.html I'm sure you can find them in Italy.

Re: [Elecraft] Dynamic Mics on K3
Giulio, I had a brain fade I just realized, I only use the Shure A95 transformer when driving the High Impedance input of my Collins. But that is something to keep in mind. The K3 input should accept the SM57 directly with the proper cable wiring. You are correct: your problem is not the microphone. By the way, I get very good audio reports with mine. Jim K9YC's suggestion to roll off the low end at 50Hz and 100Hz is a good one. The SM57 has quite a bit of proximity effect and you should keep your distance to at least 3 or more. I use a fairly large windscreen on mine as well. Enjoy!

Re: [Elecraft] Dead K2 After nearby power surge
Fred, In cases like yours, first step is to connect a dummy load to the K2 just in case it is trying to transmit - it is not good to enter transmit state without a load on the PA transistors. If it is a K2/100, remove the KPA100 and connect the dummy load to the BNC antenna jack on the lower rear panel. First thing is to check the state of the 8T and 8R voltage rails. Those are easily checked at the anodes of D6 and D7. If D7 anode has 8 volts on it while D6 anode has zero volts, then the K2 is in a transmit state. If both D7 and D6 anodes have 8 volts present, power it only briefly while making further checks lest some components overheat. If both 8T and 8R are present, you need to check the state of the RX signal at the gate of control board Q4 as well as the TX signal at the gate of CB Q3 - one should be on (about 5 volts) while the other should be off (near zero volts). If both of these are on, the microprocessor was zapped with the power surge, but if only one is on, the problem is a shorted Q3 or Q4 on the control board. 73, Don W3FPR Fred Keller wrote: I also just noticed that the power output transistors Q7 and Q8 are getting warm when the power is on.

Re: [Elecraft] terminal window in k3 utility
Gary, Yes, I believe you can do that. Set the K3 for PSK D data mode and tune the K3 (with a narrow filter) until you hear the PSK 'warble'. You can send using either the paddles or the text input area of the K3 Utility's Terminal tab. The decoded receive text will be displayed in the larger screen area. Be certain to select PSK 31 in the terminal window. If you succeed with PSK, you can also operate RTTY in a similar way - select RTTY in the terminal window and set the K3 for FSK D. Remember that sending IM (as one character) is the immediate stop TX indicator - otherwise there is a delay after you stop sending to go from transmit to receive. 73, Don W3FPR Gary Lee wrote: Is this actually a full duplex serial connection to the k3?

Re: [Elecraft] (no subject)
Mike, The 0 - 9 buttons are 'quick memories' and are the same as normal memories 0 thru 9. If you have data stored in the normal memories 0-9, then tapping MV followed by a tap of the appropriate button should retrieve the memory contents. If you want the 0-9 buttons to act like 'band select' buttons, then set the CONFIG: MEM 0-9 menu to BAND SEL and once settings are stored for any frequency in a band, those memories will return to the last used frequency, mode, antenna selection, filter selection on that band. You can also use the 0-9 buttons to store those memories. Set up VFO A and VFO B each with their modes and other settings. Then tap VM followed by a tap to one of the 0-9 buttons. To retrieve, tap MV folowed by a tap to one of the keypad 0-9 buttons. The M1-M4 buttons are similar, but are PER BAND. That means you must select the band first. Then you may store or retrieve the memory contents for each of the 4 buttons. Tap VM, then tap the M1-M4 button to store. Tap MV followed by one of the M1-M4 button to retrieve.

Re: [Elecraft] terminal window in k3 utility
The K3's Utility's Terminal page program uses the K3's internal decoder and shows the output on a PC screen. Although you might send with paddles, you may also use the PC keyboard.

Re: [Elecraft] Dead K2 After nearby power surge
Fred, Zero volts on both is way better than 8 volts on both - at least the K2 is not trying to transmit. Check the gates of Q3 and Q4 on the control board. The gate of Q4 should be at 5 volts and the gate of Q3 should be near zero. If that is true (and only if that is true), short the drain of Q4 to its source and see if the 8R voltage rail comes to life - 8 volts at the anode of D6. If so, replace Q4. If still no 8 volts on 8R, then something is wrong with Q2 (likely open). OTOH, if the gates of both Q3 and Q4 are near zero volts, you have a bad microprocessor output. 73, Don W3FPR PS: Top posting is preferred here, it is easier to see the latest without scrolling all the way to the bottom - on some posts it is hard to determine what has been added - I know about 'netiquette', but that is slow and laborious.

[Elecraft] K3: A nice black cover to hide the front panel MIC socket
I got tired of reaching around the mic plug on the front panel, so I made an adapter to plug mic and PTT into the rear. Then I got tired of seeing the empty mic socket. I found a perfect way to hide it, and seal if from intrusion. It looks real fine! I used one of these black vinyl cover caps made for SO-239 connectors: http://www.dxengineering.com/Parts.asp?ID=1159PLID=16SecID=127DeptID=36PartNo=DXE%2DVC%2D0612 You need to cut a cap shorter. Slip it over a wooden rod. Using a sharp blade, cut around the cap to make it half the original depth. Now fold it part-way back to stretch it, and it will snap tightly over the mic socket. You CW-only guys should really like this.

Re: [Elecraft] Dead K2 After nearby power surge
Fred, We are 'doubling' with overlapping posts here along with fast paced responses. From that brief measurement, I think Q3 is the problem - I base that on the fact that you measure 8 volts on both D6 and D7. Just remove Q3 to check that theory. The K2 will receive without Q3 installed, but will get mixed up if you try to transmit. If you get receive and a display with Q3 removed, then a new 2N7000 should fix it. BTW, you cannot check a transistor or FET for short/open by making resistance measurements - it is just not reliable nor predictable. 73, Don W3FPR KC9QQ wrote: KC9QQ wrote: Don Wilhelm-4 wrote: Fred, In cases like yours, first step is to connect a dummy load to the K2 just in case it is trying to transmit - it is not good to enter transmit state without a load on the PA transistors.

Re: [Elecraft] K3/100 Assembly - KSYN3 Installation
Hi Walter, Don't know OBTW but on some male connectors unused pins are cut to use as keys. I don't recall this being one of them, however. There is no easy way to plug the KSYN3 in backwards but it's possible the key is added to keep the connector from being misaligned If there is a keyplug inserted into the matching female pin hole, then this is certainly a key pin. Elecraft doesn't screw up things like this. Pins 3 and 6 are n/c, so it's likely your cut pin is pin 3, and it's being used as a key. Check your schematics to be sure that it's pin 3, then move on.

Re: [Elecraft] terminal window in k3 utility
Bob, There are 2 'modes' - the first is DATA mode set by the MODE switch, and the second is the type of data mode set by the DATA MD button. The K3 must be in DATA mode, and to use the paddles for transmit, the DATA mode must be set for PSK D (psk31) or FSK D (rtty). I am not certain how hams like you and Gary would know the correct setting for the mode and DATA MD unless you first have a sighted helper or other assist to read the display. 73, Don W3FPR Bob Garrett wrote: Hello Don, When I go the the digital mode on the Mode switch and atempt to send using the paddles, nothing happens.

Re: [Elecraft] K3 and PSK31
If you're using Data A, make sure the CONFIG:PTT-KEY setting is correct to actuate TX. For example DTR-OFF lets the DTR signal key the TX. Digipan can accommodate this too. Data A is a good choice for this. The K3 is an excellent data radio and this mode supports PSK31 quite well. 73, matt On Thu, 12 Feb 2009 00:37:30 -0600, you wrote: OK, Stupid question, I can't believe I can't get this running.

PSK31 operation PC to K3, Digipan (then HRD/DM780 when I get it figured out, one thing at a time). Windows XP pro, Digipan, both signals checked on the comm 1 port for transmit, NO Rigblaster, serial cable direct to 1.7 gig PC, sound card on the mother board, K3/100 (plus options). What mode am I supposed to have the K3 in? 1. Data, Data A, vox or not = won't go into transmit. 2. USB mode, goes into transmit and transmits data as expected except that the frequency is 600 Hz above the VFO setting and does not follow the waterfall frequency. Works fine on 746 through original Rigblaster, I didn't think it was supposed to be needed on the K3.

Re: [Elecraft] K3 and PSK31
Jim, The K3 does not know the Digipan waterfall frequency. If you are to know the actual transmit frequency that would have to be calculated by the Digipan application rather than the K3 display. 73, Don W3FPR Jim Miller wrote: 2.

Re: [Elecraft] m1-m4 memory buttons
To all who responded thanks! I was missing the M to V step. For some reason I thought you just hit the M1 or M2 key and it would pull the memory. I have not tried it since all the replies but I am sure that will fix it. Thanks again. A slip of the foot you may soon recover, but a slip of the tongue you may never get over.

If you have data stored in the normal memories 0-9, then tapping MV followed by a tap of the appropriate button should retrieve the memory contents. If you want the 0-9 buttons to act like 'band select' buttons, then set the CONFIG: MEM 0-9 menu to BAND SEL and once settings are stored for any frequency in a band, those memories will return to the last used frequency, mode, antenna selection, filter selection on that band. You can also use the 0-9 buttons to store those memories. Set up VFO A and VFO B each with their modes and other settings. Then tap VM followed by a tap to one of the 0-9 buttons. To retrieve, tap MV folowed by a tap to one of the keypad 0-9 buttons. The M1-M4 buttons are similar, but are PER BAND. That means you must select the band first. Then you may store or retrieve the memory contents for each of the 4 buttons. Tap VM, then tap the M1-M4 button to store. Tap MV followed by one of the M1-M4 button to retrieve. W0MU Mike Fatchett wrote: Ok I read the manual and I have been unable to program the m1-m4 keys or the 0-9 keys. I can program a normal memory just fine. Is there a menu setting that I am missing or did I have to do something in the K3 utility program to get this to work?

Re: [Elecraft] Terminal for Mac users
I hadn't realised the Mac version didn't have it and it explains a few questions in my mind when people said here they had done something, I misunderstood what was being done, since I didn't realised the Mac was missing functionality. So David, yes please, do implement the same functionality to the highest degree possible in all 3 architectures. Having this facility for all 3 is quite a big cornerstone in the Elecraft arsenal and another reason why the K3 is SO GREAT. And although not a big user of cocoaModem, I'll second that sentiment, Chen puts a lot into his software. And being an ex-Apple engineer, you can bet it's 100% cocoa and done 'the right way'. You should look at some of the other software there too, all good stuff. 73 de M0XDF, K3 #174 -- When one tugs at a single thing in nature, he finds it attached to the rest of the world. -John Muir, naturalist, explorer, and writer (1838-1914) On 12 Feb 2009, at 04:45, David Fleming wrote: I guess I'll get busy and finish coding the terminal page. :) Other than a conversation I had with Greg, I don't recall any other Mac users mentioning the Terminal. I find it difficult to put much effort into something that no one will use. Now that I know it's wanted, I'll get it done. In the meantime, for those wanting to work digital modes on the Mac, I HIGHLY recommend you take a look at Kok Chen's cocoaModem. It is, IMO, the finest digital mode application out there - on any platform. http://homepage.mac.com/chen/w7ay/cocoaModem/index.html David, W4SMT __ 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
