Re: [Elecraft] OT 4M
Regardless if the US will be getting 4meter ham band privileges, there are already at least two mfrs making 4m transverters so wonder if that is a market Elecraft would be interested in entering. I have a contract to build a L70-28 25w DEMI transverter kit for a ham in Finland this month. He will be using it with his K3. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubus...@gmail.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 Message delivered to arch...@mail-archive.com

The K3 is a superhet transceiver with narrow ham-band filtering in the front end (averaging about 500 kHz, varying with band). This reduces out-of-band interference to the P3 panadapter, which is tapped in just after the mixer. A view 200 kHz wide is about the most needed for typical operating scenarios. This width is also consistent with the narrowest of the band-pass filters. A direct-sampling SDR can view a wider swath of the band for the same reason that it has 15-20 dB lower blocking dynamic range than a well-designed superhet: the A-to-D converter is not protected by narrow filtering. 73, Wayne N6KR __ 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

[Elecraft] Looking for a K1
I am interesting in buying a K1 for 80metres. Do not really have the time to buy a kit and build one, out of interest any idea how long it realistically takes to build a K1 kit? But would really prefer to get a K1 with the 80 metre option. Why? there are quite a number of QRP CW contests in ZL, and I reckon a K1 would be good for those. I am not enough of a saint to trust myself in the heat of the moment not whack the power up on the main rig (ft102) and nail just that contact. If anybody has one, please let me know.

[Elecraft] K3 Birdie on 147.48 MHz
All, I notice an S7 spur on 147.48 MHz, which is our local CERT simplex net. Using an HT, it seems strongest right above the LCD display on the rig. It wipes out copy of weak stations on a separate mobile rig as well. Spur is unchanged with any setting on the K3 and does not go away when the P3 is turned off. Spur goes away when the K3 is powered off. K3 s/n 5820. Unit has no 2m transverter board installed. Has anyone noticed this? Sounds like computer whine. Any way to mitigate this, or at least shift it to another frequency? Makes it tough if we had to relay 2-meter traffic onto an HF net during an EMCOMM situation.

Re: [Elecraft] K3 - Accessory Jack - How Many Wye Cables?
Mike, Any "Y" cable that has all 15 conductors connected straight through with none connected to another pin will work.

An SVGA "Y" cable should have all conductors independent, but verify that with the cable supplier or check with your ohmmeter if you already have one in hand. 73, Don W3FPR On 5/19/2014 8:52 PM, Mike VE3YF wrote: One question, is there a particular Y cable I should be looking at or will any Y (Wye) cable work, ie for Video Card to Dual Monitors.

Re: [Elecraft] 4M Question
Overstatement seems to be the norm in everything these days. :-)) Not exactly "disallowed." NorCal Hams have gotten along with the Air Force and their big radar for decades. Their mission expanded, some mods to the radar, and, through the FCC, they asked for reductions in repeater field strength at the radar. The mitigation requirements varied all over the place. Some required just moving the 440 antenna to the other side of the tower. Some -- Mt. Diablo for example [directly in front of the radar] -- were pretty severe, in the 45-50 dB range, which is pretty much "not on the air." The requirement for the NCCRA/Cactus system on Bald Mt [K6SRA] was 35 dB which we were able to achieve by lowering the power about 7 dB and putting a directional antenna on the 440 with a 32 dB side null aimed at the radar. Thanks to fortuitous geography, the forward gain compensates for the power decrease, and our coverage into the Lower Sacramento/Upper San Joaquin Valleys is still very good. The null unfortunately passes right over my QTH, but from home with a small beam, I'm fine. :-) The radar scan limit is a line about through PHX. Our Squaw Peak system received no mitigation requirement. Incidentally, to the best of my knowledge, there were no mitigation requirements issued for stations transmitting below 440 MHz. Having had a tiny bit of experience with PAVE PAWS in a past life, I'm not surprised. If 70 Mhz becomes an allocation, I'm pretty sure a 70 MHz xverter from Elecraft would be a good product. Depending on the size of the allocation [if it happens], it might be interesting to not do repeaters there and leave it open for all the other things we do with our radios. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 5/19/2014 4:07 PM, Rick WA6NHC wrote: 420-450 is disallowed over much of the state (150 miles circumference from Beale/PavePaws)...

Re: [Elecraft] 4M Question
As an experiment, one cold and rainy weekend (about as close as we get to winter) last year, I programmed all of the local 2m, 220 and 440 repeaters into a scanner and let it do its job. Surprisingly, compared with 10 or so years ago, most were dead quiet. Back then, 220 was a nice alternative to the crowding and overuse of many of the 2m repeaters. And 440 is definitely a different story here. Most are closed or private. I'm not debating the fairness of this phenomenon; just stating a fact. Most of us have one or a few favorite repeaters anyway.

Re: [Elecraft] P3 adding rf protection diodes question
Eric: I would suggest an Elecraft adapter kit for the P3. The kit would contain the elements you suggest except an external battery pack and handy carrying handle. I would add ESD protection to the P3A? I think the P3A and kit would compete favorably with other commercial RFI tools costing 10x$. I can see a book in the future, 'Chasing RFI with the P3' as well.

Re: [Elecraft] P3 adding rf protection diodes question
Hi Joe. I think you could use the 1n148 diodes and they should be OK across the input of the Elecraft P3. The problem is from larger static voltages that could destroy the solid state devices in the P3 but with the two diodes back to back the static voltages should be held to 0.6 volts and that low voltage should not cause any failure. The 0.6 volts may even be better than the 0.3 volt of the 1N34A as there will be less chance of inter mod distortion. 73 and good luck finding your noise.

Hi Pete, Here is a redux on the response to the question I got, both on list and off list: It should be OK to use them if: 1. They should be snugged onto the felt, and not left to free wheel. Reduces the downward load by providing a surface to rest against. 2. If you ship the radio anywhere, or subject it to shock, you should remove the knobs. Again, same reason as #1. 3. Many people have stated that they have had the knobs on for years with no issues. As a result of the answers, I have mounted mine, slightly snugged to the felt. This reduces the "spin" factor, but I was worried about the encoders. -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Mon, 2014-05-19 at 09:44 -0400, Pete Smith N4ZR wrote: > I sorta think the issue ought to be why *not* to use them.

Re: [Elecraft] K2 #6951 "It's Alive!"
Hi Don, My kit is #1089 March 2000, but I was responding to a post by kit owner #6951. Sorry I said 2M when I meant xverter interface. I bought these changes and mods in July 2003, but hadn't really gotten much built by then... BFOMDKT VFO ALC/10M mod parts kit K2 Temperature Compensated PLL Reference Upgrd K2 MCU and IOC firmware upgrade K2 Rev A to B upgr parts 2nd Filter Upgrade for the K2 then in October 2009, I bought these mods and upgrades getting ready to build the rest of the kit... K2 MCU and IOC firmware upgrade 2.04 KSB2 B/W Upgrade Cap Kit Matched Filter Crstals (14) then in later October I bought these options...still planning to re-start building... KAT2 K102 Built the K2 by 2011 incorporating all the changes and mods without removing and resoldering anything... then I bought KAF2 and KBT2 The K2 works perfectly...

Re: [Elecraft] I got big heavy knobs...
There was an issue mentioned by Elecraft (Eric I think), that they had seen some failures of the encoders fitted with heavy knobs when the K3 had been in transit somewhere, UPS/USPS etc. Vibration and the greater weight of the knob can produce a damaging cantilever effect, much as is the case with a front loading washing machine! 73 Stephen G4SJP On 19 May 2014 14:44, Pete Smith N4ZR wrote: > I sorta think the issue ought to be why *not* to use them.

[Elecraft] P3 adding rf protection diodes question
It was mentioned to put a couple of diodes across the P3's input to protect it. Do the diodes need to be 1n34a's or would 1n4148's be ok for that application?

Re: [Elecraft] Question about the KX3
I've already gone through both the operating manual and the assembly manual. Having built a number of computers from the ground up, the KX3 looks to be on that level of difficulty, albeit squeezed into a tiny package. This will be my first HF rig, as I passed my general test on 7th of May, so I'm still learning about the differences in the rigs that I now have available to me. While I was at Dayton, I played with a K3 and liked the way it felt and handled a KX3 and liked it as well. Next question that I feel the need to ask: in all of the photos on the website of the KX3 there is an antenna plugged into the BNC jack on the right side of the radio. What antenna is that, and does it come with the kit? (I'm taking a gander toward no, but that's ok because I have a G5RV Mini that I still need to put up. Just waiting on a radio to attach to it...) I have to hand it to Elecraft, the manuals are top notch and they do something that no other manufacturer does: explain in plain English what a function does and why you would want to use said function. 73, Joshua Gould K8WXA On Mon, May 19, 2014 at 1:32 AM, Don Wilhelm wrote: > Joshua, > > In keeping with the Elecraft philosophy of not requiring the customer to > purchase any more than is desired, the KX3 microphone is an "optional" item. > > Certainly a microphone could be provided with every KX3 if the price were > 'bumped up' by the cost of the microphone.

[Elecraft] KX3: Change filter NORM presets for SSB/CW
Hello folks, is it possible to change the NORM presets for the filter bandwidths for SSB/CW modes at my KX3? I find it a bit annoying that SSB defaults to 2.7 kHz and CW to 400 Hz. Regards!
