[Elecraft] More hope for KX3 overheating
As promised in my previous announcement, my website has continued to evolve: 1) The new FAQs page -- which covers too many topics to mention here -- provides information that should be of interest to all KX3 owners. No doubt the most interesting information is contained in the two plots, which show how TX efficiency varies with frequency and output power. The variations are surprising, and the implications are significant! (As many KX3 owners have already discovered, 0.5 Watts output is a practical limit for high duty cycle TX on 6 meters using the factory heatsink.) 2) The Remarks page is now organized by subject matter! --- - - - --- Meanwhile, work continues in other areas: 1) My installation guide PDF file will be available for download in a few weeks. (Currently I just email it to each customer when they place an ordered.) 2) Another round of independent performance testing will commence later this month. This will be the first formal testing of my Plus (formerly known as Tropical) model. 73, Fred VE7FMN http://www.ve7fmn.ca/ P.S.

[Elecraft] KX3 4m-Band Bandlimits
Hi fellow elecrafters, 1. I am using my KX3 for the new 4-m-band (new in Germany!). I have a problem with the band-limit. In the future there will be a 4m-band from 69.9 to 70.5 MHz in region 1. When sending below 70 MHz (dummyload, hi) the message band end appears. Not so with my K3. Would a new firmware-release help? 2. It would be nice to have a transverter IF of 10 MHz analog to the K3 for my 472 kHz-transverter. Then I have not to change PWR to 0.1 Watts when I QSY to MW.

Re: [Elecraft] KX3 4m-Band Bandlimits
Where have you read that, Hans? Looking through the Region 1 papers and also the agenda for WRC-15 I can find no reference to the 4 metre band. The only thing that could affect the K3/KX3 would be the band within 5250 and 5450 kHz. At present the K3/KX3 will only transmit up to 5420kHz. For a future WRC there is a possibility that top band will be extended down to 1800 kHz again to bring the band in line with Regions 2 3.

Re: [Elecraft] KX3 4m-Band Bandlimits
According to the specification, it should transmit between 69.9 and 70.6MHz. What mode are you using? If it's CW then there's a problem, if FM, maybe that's too wide a mode to stay within the limits? In Germany I know a couple of Amateurs have licences for 69.950MHz, or a nearby frequency, to transmit and, of course, in the UK we already have 70.000 to 70.500MHz.

Re: [Elecraft] P3
Even if you manage to bring out the IC-7600's IF, the problem is that the radio's IF is around 64 MHz but the max frequency that the P3 can accept is about 33 MHz if I remember correctly. Simply put, there's no easy way do connect a P3 to the IC-7600. (If anyone knows of a way, I'd sure like to hear about it.) However, there ARE methods that will provide a much improved panadapter/waterfall display over what shows on the radio's screen. There's an easy mod that uses a Mini-Circuits or other brand, two way splitter to bring out the IF scope signal. You basically pull the coax line from the IF to the scope input on the board inside the radio and insert the Splitter such that one of it's outputs goes to the original scope input connector and the second splitter output goes to the outboard device. Usually a simple dongle SDR or LP-Pan is used with a computer program for a much improved panadapeter waterfall display. Another somewhat more costly way is to use the same splitter between the Rx-IN RX-OUT connector to drive something like and SDR-IQ or as I am doing, a QS1R SDR receiver running SDRMAX V + Omni-Rig. The SDR basically runs in parallel with the IC-7600 and Omni-Rig allows master/slave functions between them. It's a lot of stuff to turn on, but you'll be rewarded with a spectacular screen of info. 73, Charlie k3ICH - Original Message - From: anel...@min.midco.net To: Elecraft@mailman.qth.net Sent: Sunday, August 03, 2014 1:22 PM Subject: [Elecraft] P3 Has anyone hooked the P3 to an Icom IC-7600?

Re: [Elecraft] KX3 4m-Band Bandlimits
Many countries have or say that they are allocating frequencies in the 4M band David. Whether or not discussed at IARU. I think CEPT have recognised that it's happening in their footnote EU9 to the CEPT agreement. A few German stations had been given spot frequencies arround 69.950MHz to transmit on using something similar to our NoV system, but until the end of August there's an allocation of between 70.100 to 70.030MHz for German Amateurs.

[Elecraft] [KX3] 2 meter module caution
I received the 2 meter module and installed it Friday afternoon. After installation, it did not work - no transmit or receive. I opened the KX3 up and discovered that the local oscillator cable had been pulled out from the coax connector at the 2M module end. I think that when I first reassembled the KX3 after installation, the cable was pinched between the top and bottom halves of the KX3 and and pulled loose. There is no warning that this might happen in the manual so I suggest you use caution. The cable is quite long and has a lot of freedom to move and can end up pinched. Elecraft is sending me a new cable - thanks. I have a temporary fix where I tack soldered the cable center conductor and shield to the 2M module board and all is working well.

Re: [Elecraft] Auto Notch Revisited
You need to qualify LMS with for FIR adaptive filters, as least mean square (least squares) has a much longer history in statistics. If I understand it, it is the simple algorithm used in (early) modem equalisation filters, because it is cheap to compute. The problem with it in the context of this thread is that it needs a value for d(n). Although d(n) is confusingly defined in the actual article, I believe it represents the correct (desired) output of the filter. That is easy in a digital system, where you can determine it by slicing the output of the filter (and possibly running forward error correction), but the context of this thread was the use of the auto-notch on voice signals. In that case, it takes human intelligence to work out the general nature of the correct signal, and even then that doesn't give you the exact waveform. What I guess you must be doing, for voice, is using an expected signal of silence (d(n) = 0) and hoping that the voice signal is sufficiently uncorrelated that the filter fails to converge on to it, but only onto the, simpler, interfering carrier(s). -- David Woolley Owner K2 06123 On 02/08/14 01:39, wa9fvp wrote: If your interested in some technical stuff, there's a very good tutorial about the LMS algorithm on the National Instruments web site.

Re: [Elecraft] Auto Notch Revisited
In the context of the LMS filter for FIR notch filtering and noise cancellation, one common way to find the reference is by a simple delay of the input signal. If the purpose is to separate voice from a sinusoid, then one utilizes the fact that a sinusoid has a long correlation function in time compared to voice. If the delay is longer than usual correlation time for voice, one will get a reference for the desired signal - at least in the correlation domain which is what counts here. For a noise reduction filter, the delay is often shorter, as noise has short correlation time compared to a voiced signal.

You'll need to add a buffer amp, at the very least, like this: http://www.cliftonlaboratories.com/z1_buffer_amp.htm Normally this would be used with a softrock rather than a P3, so I haven't really looked into what else might be required to integrate and make the K2 work with the P3. 73, Matt VK2RQ On 4 Aug 2014, at 7:06 am, Thomas Taylor li...@comcast.net wrote: Has anyone on this list used a P3 panadapter with the K2 transceiver?

Re: [Elecraft] P3 panadapter with K2?
Has anyone on this list used a P3 panadapter with the K2 transceiver? Is it directly plug compatible or does it need a custom interface/cable and where can that be obtained? Thanks, Tom KG7CFC It is not directly plug compatible, as there is no IF output port on a stock K2. Even with a modified K2, the P3 cannot achieve the same level of integration that it has with the K3. To study up on a couple of different ways to accomplish an IF output on the K2, you can read up here: http://www.cliftonlaboratories.com/k2_interface.htm GL, Bruce, N1RX __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3 won't power up
I have a k3 that was working fine but now will not power up. I had lent the unit to someone to use at Field Day. They reported it would not power up. Going through the unit it appears that a nut and washer has come off of one of the PL259 antenna plates. A thorough internal inspection found a loose washer but no nut. There is nothing evidently wrong inside, no flashing, no sparking, no burning odor. It just won't come on. Fuse did not activate. I am going to call the factory tomorrow but anyone have any ideas? __ 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 Message delivered to arch...@mail-archive.com
