Re: [Elecraft] Love me K3 line
Once you have a reasonably loud signal and an antenna that allows you to hear the DX, the most important attribute of a DX-oriented station is agility. You can tune the bands and when you hear something you need to be able to jump on it instantly. Get him before he's spotted and the pileup builds up. That's where the no-warmup, no-tuning KPA500 helps. Once the pileup is going, you need to find the stations the DX is working and figure out the operator's pattern. That's where the subreceiver and the P3 are useful. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 1 Feb 2016 03:09, Paul VanOveren wrote: I have worked both S Sandwich and S.

Re: [Elecraft] Love me K3 line
I don't get it to be honest. Why is there an obsession with 1500w? Seriously, I do not believe I have 'missed' working a popular DX party because I DON'T have 1500w to play with. I do know that I can be heard amongst the cacophony of noise in a pileup. Does that make me work harder?sure it does, but I still get the same thrill of the contact and I don't have as much qrm issues in VK either..it's all relative? I like my no nonsense kpa500, no more tuning up issues, no expensive amp ir tubes, instant on etc Yep I have had a big tube amp in the past and I genuinely don't miss it, really.

[Elecraft] Lack of low freq response K3 ssb rx audio
I made some spectrum curves of the 4KHz BW rx passband with FC of 1.00, 1.50 and 2.00 to illustrate what I'm talking about. This list bounces image attachments so if you're interested, please look at them here: http://k3s.wikidot.com/ The posted curves have been verified on another K3 and RX EQ is flat. My original question was: Why does the audio passband dramatically roll off in the lower frequencies as my Shift/FC goes above 1.40Khz? I think the spectrum curves partly answer the question. They reveal a a maximum passband width of 3300Hz (-3dB points) in SSB even though BW is 4000Hz, within a 6KHz wide roofing filter. I don't understand the discrepancy between selected bandwidth and what the K3/K3s is providing. For comparison, a passband curve in AM mode is also shown and it reveals extended flat response from below 50hz to almost 4000Hz. 73, Barry N1EU > > On 1/31/2016 9:02 AM, Barry N1EU wrote: > > I'm pulling my hair out on this one, but let me keep it real simple.

Have used them for years and haven't had any failures. I use them for all systems I build for clients and myself. They have several varieties for each size and the ones with rubber mounts are generally the most quiet. Also have a choice of 3 and 4 pin plugs. While most of their fans come with rubber mounting hardware, the ones I suggest have rubber inserts surrounding the bolt/screw holes. Noctua is an Austrian company but fans are built in the orient. Top quality with 'SSO2' bearings. Both Amazon and Newegg have them and the prices generally run from about $15-18. Just make sure the specs (CFM) match (or are better). While I haven't measured them on mine, they look like 80mm. Jim AB4AC Jim Finan Sent from my BlackBerry 10 smartphone.

My original fans are pretty quiet but at this time of the year when the windows are closed and the ambient noise level is nil, the fan noise really starts to bug me. It's the very slight rattle they make when they start winding up.. (In the din of summertime, can't hear myself think, let alone fan noise.) Sources? Prices? Are the newer Elecraft fans quiet? My PA is only a couple of years old so the fans are pretty recent model. 73, Drew AF2Z __ 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 jimfi...@att.net __ 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 jimfi...@att.net __ 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] WTB KX3
Tomy, The options you select for the KX3 will mostly be determined by your operating aspirations and your antenna system. If you do not have resonant antennas for all bands, then you will want the KXAT3. If you envision portable operation working on batteries, you may want the internal battery charger. If you are operating in a DX pileup or contesting situation, you may want to add the KXFIL3 roofing filters. If you want 2 meter capability, then add the 2 meter option. In other words, give thought to your antennas and the operation that you anticipate with your KX3 and you will be able to configure it to best suit your needs. 73, Don W3FPR On 1/30/2016 12:24 PM, Tomy Ivan via Elecraft wrote: Looking to buy a nice KX3 Package.Please let me know what to have. 73!

[Elecraft] RF Exposure Levels
Thanks, Bob. I received a couple of other private replies raising the same question, about RF exposure using an amp and an indoor antenna. There is an RF exposure calculator available on the ARRL’s site, or directly at http://hintlink.com/power_density.htm. My configuration at 100 watts is only about 1/4 of the safe maximum. Nonetheless your caution is appreciated and well advised - hence my posting the calculator site here for any others who might be sitting close to their antennas.

Perhaps the "Tuner issue" is an indication of such. From your description, at 100 watts you will likely be way outside of the FCC limits of safe RF Exposure. Now with that said, the amount of RF at the TUNE level is not such to confuse the tuner. However at 40+ watts the RF back into the system is more than the system can accurately handle. A bunch of #31 beads or #73 beads, where "bunch" = 50 pcs or more, on the feed line at the antenna feed point and again a bunch at the radio. This may help the radio and antenna problem associated with the auto tune routine. You may find the same treatment required on the DC power cable at the radio. 73 Bob, K4TAX >-- > >Message: 21 >Date: Sat, 30 Jan 2016 18:48:29 -0600 >From: Bob McGraw K4TAX >To: elecraft@mailman.qth.net >Subject: Re: [Elecraft] KXAT100 "Hunting" >Message-ID: <56ad59dd.3070...@blomand.net> >Content-Type: text/plain; charset=utf-8; format=flowed > > >Candidly, I would be more concerned about exceeding the RF Exposure >limits with this arrangement.

[Elecraft] Lack of low freq response K3 ssb rx audio
I'm pulling my hair out on this one, but let me keep it real simple. This is on a K3s and all hardware/firmware is latest/greatest. Filter: 6KHz Mode: USB BW: 4.00KHz My question is this: *Why does the audio passband dramatically roll off in the lower frequencies as my Shift/FC goes above 1.40Khz? * I would think that there wouldn't be any bass rolloff until FC was above 2.0KHz (i.e., half of 4KHz BW). Instead, what I'm observing is: - with FC of 1.6KHz, I see -8dB at 100Hz - with FC of 1.8KHz, I see -15dB at 100Hz I'm using Line Out to soundcard and Visual Analyser 2014 software. It mirrors what I hear in my headphones. 73, Barry N1EU __ 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] Unpacking the K1 package contents
Perhaps it should be called a thermal conductor and electrical insulator but then some people always complain even if hung with a new rope. 73, Fred, AE6QL -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Ron D'Eau Claire Sent: Saturday, January 30, 2016 4:34 PM To: 'Mark Petrovic'; elecr...@qth.net Subject: Re: [Elecraft] Unpacking the K1 package contents Hello Mark: The "thermal insulator" is a thin flexible rectangular bit about 1/2" by 3/4" in size that has a hole near one end and is self-stick, so it is supplied on a bit of backing paper you peel it off of when you install it on the power transistor. It may be in one of the little brown envelopes. There is a photograph of it still mounted on its backing paper in the parts list. The Acrylic Bezel is the plastic cover over the LCD on the front panel. Look at the drawing of the K1 on the front cover of your manual and you'll see a rectangle depicting the cover with a screw at each corner covering the LCD itself and the words "Elecraft" and "K1 Transceiver".
