[Elecraft] KX3 roofing filter query
Hi, I have installed the optional roofing filter into my KX3 #4559. The manual advises that bandwidth switches to 3000Hz when Weaver demodulation is in use on SSB. However when I reduce the RX passband to 2.4KHz, which is when Weaver is supposed to kick in, it stays on FL1, until I reach 1.7KHz. At this point, FL2 is activated, however this is so narrow that it is close to unintelligible. Is this normal, or am I missing something? Maybe using width/shift rather than Hi-lo cut doesn't activate Weaver? I would much appreciate some enlightenment as to how it all works, as I'm mainly interested in close in rejection, without having to discern which side the intrusion is coming from. Also I find anything below about 2KHz bandwidth too difficult to discern.

Re: [Elecraft] KX3 roofing filter query
Chris, The fault is in human ears and their perception of human speech. There must be some content in the 300 to 600 Hz region to maintain intelligibility. Using Hi-Cut only, you should be able to reduce the high end to about 1500 Hz while still maintaining intelligible speech. But if one tries to cut the low end much above 400 Hz, you lose intelligibility fast. If you are using width/shift, you will have to reduce the width and then use shift to regain intelligibility. IMHO, it is easier to use Hi-cut and just cut the high end while leaving the low end at 300 Hz. 73, Don W3FPR On 7/31/2013 5:24 AM, Chris Meagher wrote: Hi, I have installed the optional roofing filter into my KX3 #4559.

Re: [Elecraft] K3 deaf on 6m comparing to a FCDP+ ?
I use a separate 6m preamp for the K3. Helps out tremendously. With the advent of the new PR6-10 on sale, you can pick up a PR6 off the reflector for sale. I recommend it highly if you want to use the K3 for weak signal work. I also use a Collins laboratory preamp from Dr Jack Smith (he is on this reflector) and that works great on 6m plus HF. Good luck!

Re: [Elecraft] KX3 Beta firmware rev 1.54: CW transmit in SSB mode (etc.)
Hi Richard, If it really is 12 V, the voltage might be too low. I don't have the manual for the charger at hand in the moment, but I think it says it would like to see 13.8(?) V or something very close to this.

Re: [Elecraft] KX3 Beta firmware rev 1.54: CW transmit in SSB mode (etc.)
You can view the battery voltage using DISP, then dialing to the BT entry with VFO B. Your power supply voltage may be set too low to use for charging the internal battery pack. If you could raise this voltage to 13.0V or higher, you wouldn't see the warning when trying to charge. 4.5A at 12V is plenty to run your KX3, but that voltage isn't high enough to allow the charging circuit to operate. Just raise the PS output voltage if possible. With that supply, you will be able to charge at the same time as operating the KX3 in any mode. See the owner's manual section, "KXBC3 Internal NiMH Charger" on p24. 73, matt W6NIA =-= On Wed, 31 Jul 2013 08:37:43 -0400, you wrote: >is there a way to add a option under the firmware to show what the >current batt charge status is ? >so you know if you need to charge or not. > >also I have a 12v 4.58 amp power supply I am using and I get a lower >supply warning when I try to >charge the batt with the radio in standby mode > >should 4.58 amp 12v not be enough to charge ?

[Elecraft] K3 deaf on 6m comparing to a FCDP+ ?
Hello Erwin, No doubt K3 is deaf in 6m. This is the reason why there is PR-6 or PR6-10 pre-amp offered by Elecraft. Upon the installation of those pre-amp, K3 is in par with other radios in 6m under the same class. Apart from the choices from Elecraft, you may consider http://www.ha8et.hu/ extra-6 which is contest grade pre-amplifier. To be fair to K3, if local RF noise is high in your area, pre-amp will not help you anyway.

Just a reminder that the K3 also has CW-in-SSB capability. It is activated the same way as on the KX3: Go into the CW WGHT menu entry and tap '1' to switch to "SSB+CW".

Not sure if you remember, but you gave me guidance/encouragment some time back, when I was trying to get into Hamlib, for other needs. Sadly, that opportunity passed by, as much caused by me using Cygwin on Win2k, and the yawningly long build times as a result.. Also, as I found the Skanti radio I had that time, was also very slow to respond to commands, so. Anyway. All understood re the above K3/KX3 history in Hamlib, function/filter naming and such, and indeed for the same version Fldigi, Hamlib's use with the KX3 is about the same on Windows (XP..7 and Linux.) I'm going to look at the filter selection options, as the K3.xml file for Fldigi does much the same as Hamlib (selects RTTY filters, for "Data" modes) OK for RTTY, but useless for anything else (unless you like to monitor two PSK signals perhaps) I'll see what I can discover and do with the .xml file first off, then report back. But for general use "USB" cut's it at present, so long as you have manually disabled compression, and equalisation etc. Tuning and TX/RX control all work fine. The better option for KX3 users, is to use Flrig as the radio interface for Fldigi, (select the K3 option in the radio configuration dialog) as it is posible to get the "DATA" filter set correctly with that, then AFIK any manually set equalisation (TX and/or RX) plus compression etc, is automaticaly disabled in DATA mode, but the settings remain for when you revert to manual voice modes. Select DATA in the filter control dropdown, then the bandwidth you want, and use the IF Shift control to center it where you want. Typically, 3000Hz width, and 1500Hz center. (The shift defaults to 1000.) The KX3 of cou

Did you read the voltage spec on the listing? This charger is rated for 19vdc at 3.95 a Your KX3 is rated for 8-15vdc. You should NEVER turn on the KX3 with this power source connected! Otherwise it will be Bye-Bye KX3 and Bye-Bye waranty (I would guess). Same CAUTION goes for using "wall wart" types of charger cubes. Typically they rise very high in voltage unloaded. Use a voltmeter to measure any power supply before connecting to an expensive piece of equipment (note if the voltage polarity is correct). Experience of 45-years and a million miles of workbench riding! DON'T ASSUME - Measure! The MFJ charger that was cited sounds like a better-safer way to go. If you need voltage about 14.2vdc to get good charging most of these have an internal voltage adjust pot. Again measure it if you decide to "adjust"! 73, Ed - KL7UW http://www.kl7uw.com dubus...@gmail.com "Kits made by KL7UW" __ 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

Hi dear Rudi, yes so far I learned that a preamp is needed for serious 6m operation with the K3. TNX for your info as well. * As you write you use also the FCDP+. How do you use it together with the K3 ? Is there any circuit out there ? Or better is there any hint to connect it to the K3? * Would be nice to have such a solution. * 73's Erwin/DK5EW Am 31.07.2013 20:54, schrieb hb9...@bluewin.ch: Hi Erwin, I own an "old" K3 (#1212) and a FCDP+ too. Without a PR-6 (or an other low noise preamp) i admit that the FCDP+ is better on 6m, speaking of sensitivity only. I bought the PR-6 after the K3, when i was a little bit disappointed with the K3 6m sensitivity.

Hi everybody, since I own a FunVubeDonglePro+ I think my K3 is a bit deaf comparing those 2 rigs on same antenna. Even with switched on preamp on the K3 it's sensitivity is worse to the FCDP+ I only heard about that the K3 is deaf on 6m but never had a comparison. Is there a fix to make the K3 hearing better on 6m ? __ 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] KAT 2 Woes
I was reaching the final stages of installing the KAT2 to my K2. When I added power, I heard some sizzling and smelled smoke, This didn't happen with previous power up testing and the build and testing seemed to go without problems. I noticed that U1 was warm. Careful inspection showed that when I plugged J8 into the Control Board of the k2, I inadvertently shifted the plug up one space, causing the wrong signals/voltage to go down the wire. Corrected that and proceeded to test. The menu for the ATU appeared without problems and the Ant1/2 cycled on and off appropriately. When Checking voltage on U4, during TUNE at 5 , I only get 0.3 to 0.4 volts. The manual suggests that there is a problem with the build of the SWR bridge. Will check that, but my question is did I fry U1 and could that be the cause of what I see?
