Re: [Elecraft] K3 front panel encoders
I replaced all four encoders ( with help from my friend ) couple of days ago. It was quite a job as the whole front panel has to be taken into pieces and DSP boards has to be taken off. A good SMD rework station is recommended to clean through holes + experience in rework not to damage foils in PCB. New encoders are bit thicker so height difference has to be taken into account while assembling . New encoders work smooth and great. One notice, be careful when taking off the knobs as at least RIT encoder is not having nothing else than small soft metal clips holding it together ( Encoders metal nut has been left out as there is no room or thin enough nut was not available at the time mine was built ) BR Olli OH6CT > -Alkuperäinen viesti- > Lähettäjä: Elecraft [mailto:elecraft-boun...@mailman.qth.net] Puolesta > SA2CIR > Lähetetty: 30. joulukuuta 2014 23:19 > Vastaanottaja: elecraft@mailman.qth.net > Aihe: Re: [Elecraft] K3 front panel encoders > > Thanks for informative pictures and writing!

[Elecraft] K3 front panel encoders
Has anyone figured out how to clean or fix front panel encoders (SHIFT/LO , HI /WIDTH) ? These cheap ( ~ 0.5$ encoders ) in my K3 has always been quite " jumpy " i.e. value jumps up and down in random steps . Also the" feeling " is not what you would expect form rig in this price range. Similar issue was in FT-1000MP RIT encoder in 90s . Dust got inside the optical encoder and turning RIT knob jumped frequency steps quite randomly.

Re: [Elecraft] K-3 with High Current Problem on 20 meters
I had the same problem on 10m. My power supply ( 30A max ) had a voltage drop from 13.8V to 12.5V on 100W output. I was instructed by Elecraft to " increase the power supply voltage to 14.0 to 14.5VDC under no load, and make sure the is as direct of connection as possible between the power supply " Then my power supply voltage was dropping from 14.5V to 13.8V ( looking from K3 DC voltage meter ) This cured my problem at least in home use.

Re: [Elecraft] K3 keying the KPA-500 & transverter
Hi Toby, if my memory serves me right (digged into the schematics about 7-8 month' ago when I had a problem with one of the key-out jacks) this will never work as both key-out pins share the same circuitry. It's just different "final" switching transistors (and thus different loads possible) that distinguish both. A solution around this could be the band specific PTT solution of WW2R/G4FRE (http://g4fre.com/K3_PTT_sw.htm) or something similar. The key is to use DIGOUT0 or DIGOUT1 to control external switching. It can be configured per band. 73 & gl, Olli - DH8BQA - Original Message - From: To: Sent: Monday, April 11, 2011 10:33 AM Subject: [Elecraft] K3 keying the KPA-500 & transverter > Hi, > > I plan on using my K3 with the KPA-500 and my Kuhne 144 MHz transverter. > > I would like to use the ACC (pin 10) Key-Out for the KPA-500 and the > RCA/Phono Key-Out jack for the transverter.

Re: [Elecraft] K3V - another new product speculation
> That is an extremely small market. There is a reason the rigs you > mentioned are no longer around. Serious ops go the transverter route. The problem is that there are NO good VHF/UHF radios anymore! That's why the serious OPs MUST go the transverter route. Believe me, there's quite some market in Europe for really good VHF&up equipment. We have a high population density here with lots of active stations. Especially during contests were the big guns do > 1.000 QSOs alone on 2 m in a 24 h contest. Ever wondered why companies like DB6NT technologies can sell monoband 20 W transverters for 1.400 EUR? Because there is demand for extra-ordinary performance. To my mind a "K3V" incl. 10, 6, 2 m with 100 W, crossband capability (satellites) and with optional internal 70 & 23 cm and 4 m modules would be a really good seller as long as it could be produced for a price as the stock K3 + 100 W amp ranges today. But surely the market is smaller than that for a K3 as is today. External transverters are rather a pain, again some extra boxes, cabling needed, a.s.o., not really portable/mobile friendly. Put it all into one package and it will be a real plus. Unfortunately this will never happen, I fear. :-(( Vy 73, Olli - DH8BQA __ 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] Voice keyer built into microphone
Hi guys, I developed a voice keyer solution that might be of interest to some of you. It is completely integrated into an MH-31 hand microphone so no additional weight and no additional space needed. Originally thought for Yaesu transceivers, then redesigned to fit Kenwood and Icom, too, it also works flawlessly with my Elecraft K3. So it might be a nice solution for all who do not have the K3 internal voice keyer module but do not want to forego a CQ parrot. ;-)) Check it out at http://www.dh8bqa.de/ssp-mh31/ssp-mh31.html A professionally produced kit is available from the German FUNKAMATEUR magazine.

Re: [Elecraft] My K3 forgets where it's at on DC failure
C'mon guys, I cannot here that "it's like a computer" argument anymore! ALL modern transceivers nowadays are controlled by microprocessors and ALL get it right to be on the same QRG after a power failure ... except our beloved K3! The last used frequency is stored into the EEPROM of the PIC (or probably external memory, haven't checked the schematics on that) when changing bands so why not already save it after no move of the VFO knob of say 5 seconds? The only valid reason not to do so that I could see (it can't be programming as the function is already there) but still struggle a bit accepting (as others do get it right) is the "fear" of memory failures within the rig's "lifetime" as you usually can only write into EEPROM (at least that in today's PIC processors) for about 1.000.000 times and that's not much depending on usuage scenarios and storing the frequency e.g. all 5 seconds. Is that the real reason why not implementing that easy functionality, Wayne? 73, Olli - DH8BQA - K3 #4546 http://www.dh8bqa.de - Original Message - From: "Ron D'Eau Claire" To: "'Dave Anderson, K4SV'" ; "'Elecraft'" Sent: Monday, February 28, 2011 5:39 AM Subject: Re: [Elecraft] My K3 forgets where it's at on DC failure > The K3 is controlled by a microprocessor, so it behaves exactly like any > computer when power is suddenly removed without allowing for normal > shutdown. > > One of the most benign reactions is that it forgets the last frequency used. > > > Just like a computer, the effects can be a bit worse, requiring reloading > the firmware. > > Ron AC7AC > > -Original Message- > From: elecraft-boun...@mailman.qth.net > [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Dave Anderson, K4SV > Sent: Sunday, February 27, 2011 8:23 PM > To: Elecraft > Subject: [Elecraft] My K3 forgets where it's at on DC failure > > Hi All, > > I am back from the TJ9PF DXpedition where I brouhgt my new K3 to use for the > 6th > station.

Re: [Elecraft] OT: K440XV?
James, if your only interest is 440 FM then a handheld or mobile TRX should be a much cheaper solution. ;-)) Having fitted the K144XV in my K3 I would not see any available space anymore to also fit a 70 and/or 23 cm transverter inside, too. With all the options space is getting rare inside. ;-)) And I don't think that lots of people would fit a "K440XV" instead of a K144XV inside meaning you have 160 - 6 m coverage plus 440 in one box but skipping 144 MHz. Sure this is no good business model, at least to my mind. ;-)) But maybe you would like to use Elecraft's external transverters which integrate nicely, i.e. besides the external box you completely control everything from the K3 itself including frequency display. Can it get any better? ;-)) 73, Olli - DH8BQA __ 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

This release includes our new APF (audio peaking filter) for CW mode, which has been helping K3 field testers work "extreme" weak DX for the past several days. For voice modes, there's a "Fast Monitor" option (TX voice monitor without the processing delay). Also included is a much-improved TX Noise Gate. This release fixes a problem with low initial output in SSB Tx. See detailed release notes below. Please send any questions tok3supp...@elecraft.com. For instructions on how to load beta firmware, see: http://www.elecraft.com/K3/k3_software.htm 73, Lyle KK7P * * * MCU 4.18 / DSP 2.67 / FPF 1.14, 11-5-2010 NOTE: Be sure to install all firmware files for this release, including FPF 1.14. Otherwise your menu text will be incorrect. * APF (AUDIO PEAKING FILTER) ADDED: APF provides enhanced copy of weak signals in CW mode, and is especially useful when signals are at the noise level. The K3s APF is patterned after the most successful analog APF implementations, and is equally effective in user tests. To use APF, make sure CONFIG:DUAL PB is set to APF. (This is the default. NOR restores the original DUAL PB function.) Then hold DUAL PB to turn APF on/off. A special DSP graphic display is used to show that APF is in effect. At the time APF is activated, the regular I.F. SHIFT setting, if any, is frozen, and SHIFT then controls the center pitch of the APF filter in 10-Hz steps. APF is independent for the main and sub receivers, as well as for presets I and II. Switching between these two presets is a convenient way of turning APF on/off quickly. * ADDED VOICE TX FAST MONITOR: Normally the voice monitor includes a ~20-ms delay, which is necessary to hear how your on-air signal will sound (with compression, etc.). If you prefer to not hear any delay in the voice monitor, set CONFIG:TX MON to FAST. Note: Youll still hear the delayed and processed monitor if you adjust the MIC, CMP, TX EQ or TX GATE settings while transmitting. * TX NOISE GATE IMPROVEMENT: The Noise Gate/Downward Expander for voice modes has smoother response and much improved performance near the threshold. * NARROW AF FILTER IMPROVEMENT: Adjusting SHIFT when using very narrow DSP filters no longer causes pop artifacts. __ 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] K3 key-out jack - configuration needed?
Hi James, you don't need to connect an outside pull-up (only if you want to measure voltages, so you are basically right as well, depending on what/how you want to measure ;-)). The transistor is used as a simple electronic switch here thus when getting bias on it's gate it will switch source (connected to ground) through to the gate (also groundlevel then, that's why you can simply measure for 0 ohm resistance between drain and chassis when keyed). If no bias then infinite ohms at drain. Anyway, thanks for your assistance and advices!

Oliver, it is a MOSFET, IRF630 and you may be right, but I would not expect to see any change until I provided a voltage source to the Key Out line. So, if it was me I would do the "pull up" resistor test I described earlier just to be on the safe side. It appears from the schematic that it is switched by the 7R line.

[Elecraft] Strange behaviour of K144XV :-((
Hi guys, after getting the missing cables today (thanks Elecraft) I immediately started installing the K144XV into my K3. Everything went together smoothly, no problems, at least hardware-wise. But, I have hundreds of birdies throughout the whole 2 m band. :-(( It does not matter if antenna connected or not, or connected to a dummyload, so I suspect these are internally and some of them are really annoying. Already checked all the TMP cable connections, everything seems okay. Furthermore when switching down to 28 MHz I now have strange noise when tuning the VFO between 28.002 and 28.007 sounding like synthesizer noise which was definitely not there before. :-(( Any ideas what the reasons are and how to solve the problem(s)? As I do not have the KRX3 module I tried to put the 12 V wire going to the other side of the mainboard to power the K144XV like shown in the manual but as the wire is so long it is laying on the mainboard. Could that be the reason, some pickup there?

Re: [Elecraft] Roofing filter for CW
One thing to remeber is that if you get strong signal within your roofing filter passband you will notice that AGC will go up to protect DSP overloading. Then you have use for narrower roofing filters. I have 400Hz but considering to add 200Hz after working couple of CW and RTTY contest on 40 meters :) Olli OH6CT > -Alkuperäinen viesti- > Lähettäjä: elecraft-boun...@mailman.qth.net > [mailto:elecraft-boun...@mailman.qth.net] Puolesta n...@aol.com > Lähetetty: 16. helmikuuta 2010 20:51 > Vastaanottaja: elecraft@mailman.qth.net > Aihe: [Elecraft] Roofing filter for CW > > > > > As a prospective buyer of the K3, and a 100 percent CW op, I > am wondering which of the roofing filters is the correct > choice, assuming I am buying only one??

Re: [Elecraft] [Elecraft_K3] TX CW discrepancy
What I have noticed is that K3 internal keyer weight changes between VOX and use of footswitch. I tend to press footswitch time to time to prevent amplifier relay sound ( AL1200 relay is loud ) but noticed this bit annoying feature after trying K3 internal keyer instead of microkeyer. The weight change is roughly from 1.10 to 1.20 ( from Vox to Footswitch ) Olli OH6CT > -Alkuperäinen viesti- > Lähettäjä: elecraft-boun...@mailman.qth.net > [mailto:elecraft-boun...@mailman.qth.net] Puolesta Igor Sokolov > Lähetetty: 31. tammikuuta 2010 16:49 > Vastaanottaja: Elecraft@mailman.qth.net > Kopio: Elecraft@mailman.qth.net > Aihe: [Elecraft] [Elecraft_K3] TX CW discrepancy > > It has started with complains of some of our contacts in the > contest.

Re: [Elecraft] K3: AGC Adjustment
I have found so many different adjustment parameters for AGC in K3 that I would apperciate " AGC settings for dummies " type of instructions. :) I previously owned IC-756PRO3 which can be used as reference of well functioning AGC among DSP radios. Very pleasant experience.

Re: [Elecraft] tx eq for K3
Hi, i discovered some days ago a significant delay in the TX SSB Monitor. I turned all TX EQ setting to 0 and hoped the delay will be smaller, but no effect for my ears. I actually have no K3, but I'm thinking to get one soon. The only point which is bothering me is the delay in the SSB TX monitor. I'm wondering if it is possible to bypass the digital filters and improve delay. I'm really not in the DSP Software (I guess this part is placed in there), but maybe it is possible to use DMA transfer if all equalizer settings are 0. I'm going to a friend with a K3 the next weekend, maybe a softwareupdate fixed the delay or improved a bit more in my direction. Last time i used it was in october. 73 Olli, DH2WQ On Thu, Jan 22, 2009 at 7:47 PM, John wrote: > Hi wonder what the average tx eq values for normal ssb? what i'm using is a > modified D104 with buffer amp and my eq setting (50 HZs thru 800 HZs -16) > (1200HZs +5) (2400HZs +0)(3200 HZs +0) audio reports have been good would > like to know what you folks are doing with your settings...John K1GUN > ___ > Elecraft mailing list > Post to: Elecraft@mailman.qth.net > You must be a subscriber to post to the list. > Subscriber Info (Addr.
