[Elecraft] 5mHz
I have searched for this question and I can't seemed to see if it has been asked before, which I'm surprised about. My K3 presently tunes from 5330.00 kHz to 5407.00kHz but the UK band now has a range of frequencies from 5258.50kHz to 5403.50kHz, so when I tune below 5330.00kHz I get the out of band message if I try and transmit below that frequency. Are there any plans to update the firmware to take into account the extra frequencies? -- View this message in context: http://elecraft.365791.n2.nabble.com/5mHz-tp7571102.html Sent from the Elecraft mailing list archive at Nabble.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
[Elecraft] K3 utility and Lbuntu 12.04
I did have a search for this, but I found no other replies, so I'm wondering if anyone else is having the same problem. I recently installed LBuntu 12.04 on my netbook which I use for updating the K3, previously it had 10.04 LTS and the K3 utility worked fine, but now with Lbuntu it doesn't seemed to work. The utility opens but it wouldn't pick up the USB port connection. I spent a couple of hours last night trying all different things, it seems like Lbuntu no longer seems to recognise ttyUSB1, I even tried installing PuTTY to see if I could change the settings using that, but no. The only way I could get around the problem was to install Ubuntu 9.10 on a separate small partition of its own and presto, without touching anything it worked, just a bit of a nuisance having two operating systems when one should do. -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-utility-and-Lbuntu-12-04-tp7557039.html Sent from the Elecraft mailing list archive at Nabble.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
Re: [Elecraft] K3 utility and Lbuntu 12.04
Thanks for that Dick, I think the only real difference is the Desktop, the Lbuntu is the light version of Ubuntu which as it doesn't have the glossy graphics heavy Desktop. I haven't tried it on the Desktop PC as it means lugging the radio downstairs to the main computer, that's the reason why I use the Netbook. I don't really want to put Ubuntu 12.04 on the Netbook as it slows it down quite a bit, I might have to stick with the work around for now. -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-utility-and-Lbuntu-12-04-tp7557039p7557043.html Sent from the Elecraft mailing list archive at Nabble.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

[Elecraft] TX EQ oddity?
I can't seemed to see this posted elsewhere so I'm just wondering if it might be a problem at my end, if someone else can confirm this please. Key transmit then tap the Main Menu then scroll to TX EQ tap the Main Menu button again to return to normal, I now find that when I go back to receive the receive frequency has shifted HF by 1.6KHz, this is most disconcerting when the QSO has effectively vanished. Luckily the station I was working was strong and I noticed the edge of his signal so I was able to tune him in with the RIT. The transmit frequency remains the same, it's only the the receive frequency that shifts. When the radio is turned off then back on again it all reverts back to normal. I have confirmed this is happening with my signal generator. Are you not supposed to fiddle with those menu controls when transmitting? I had a look in the manual but couldn't see anything mentioning that, but I might have missed it. It's not a huge problem when I know about it. -- View this message in context: http://elecraft.365791.n2.nabble.com/TX-EQ-oddity-tp5871397p5871397.html Sent from the [K3] mailing list archive at Nabble.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
Re: [Elecraft] Feature request - CW PTT
Hi Chris, The Key output works as it should do, there is no output from it at all as such. What it does do is in the transmit mode it will sink up to 200 volts at 5 amps, so in other words if you have a 24 volt relay with one side of the relay is connected to +24V and the other side connected to the centre pin on the Phono plug, then every time you operate the PTT the relay will activate, this is for operating any external equipment like linears or any other equipment that needs to be operated on the PTT line. I use this port to activate my linear, in my case I use a FET transistor as I have various lines that need activating or de-activating as the case maybe.

Our goal is to add other modes back in if there's enough interest. Each requires considerable firmware modification and re-testing. Is AM/SSB a common split? Note that you can achieve this without using SPLIT if you have the sub-receiver installed. For example, you could transmit/receive in SSB mode on VFO A on one frequency, and receive AM on the sub on a different frequency.

No matter what magic wizardry circuits or software is contained in the rig to deceive to meter into reading power, you can't beat seeing the peak power reading on an oscilloscope.

[Elecraft] Power output measurement
I've seen lots of posts regarding measuring output power. The technique I've used for years is simple and effective, all it requires is an oscilloscope. It doesn't have to be a top of the range high frequency instrument either, provided the DC scale is reasonably accurate virtually any scope will do, all that is required is to build a very simple diode probe and use a calculator to work out what the power is across a 50 Ohm load. Have a look at this site from Adam Farson, VA7OJ/AB4OJ, Fig 3 shows the simple diode probe connected to a digital multimeter (DMM), in place of the DMM use the scope. http://www.ab4oj.com/pwrmeas.html If you are measuring higher power levels use the 10:1 attenuator as in Fig 2. Just speak into the mic and watch the peaks, it's far more accurate than any meter can possibly be and far cheaper, there are plenty of surplus scopes for sale.

Someone mentioned that their power output went down when they turned the compression down and would Elecraft make power output remain constant as compression is reduced. Well, the power output (average) is *SUPPOSED* to decrease when you reduce compression. When speech compression is reduced, your peak-to-average power ratio increases. The peaks remain just as high but the average power is considerably less. This is another reason to want a 'scope to check your rig. BTW, how many people have done a two-tone test or a double trapezoid test for linearity? How many people even know what I am talking about? :-) (My first HF transmitter was a Central Electronics Multi-Phase exciter with a whopping 10W of output.

Re: [Elecraft] K3 Importing to UK
Thanks for asking that Jim and thanks Dave for confirming my calculations, I've just ordered mine and had worked out what mines going to cost. 73 Paul. Dave G4AON wrote: Hello Jim You will have to pay 17.5% VAT on the total price including shipping, it should be duty free (if they charge duty you should be able to claim it back). When I received mine back in November the amount payable to UPS was the vat plus an £11 handling fee, you would normally be asked to pay before they will deliver. Smaller items tend to arrive by Parcel Force who charge £13, not what you might call good value. The only viable shipping option when I ordered mine was UPS, as the US Postal Service didn't have sufficient insurance cover. 73 Dave, G4AON K3/100 #80 I have just decided on my K3 options and it comes to 3400 usd including shipping. Can someone in the UK give me an idea of any duty/tax or additional costs I will have to pay when it's delivered.

Re: [Elecraft] Monitoring yourself
Thanks for sharing that link Brian, of course the Netherlands isn't far from me here in the UK and it's weird hearing myself coming over a distant receiver. 73 Paul G4LNA K3KO wrote: Try listening to yourself on a web SDR. http://websdr.ewi.utwente.nl:8901/ One can listen with the above link on 40 and 80M. It is tunable and does CW.SSB and I guess digital modes. Bandwidth is also adjustable. No more depending upon some others subjective opinion of your keying and audio. You will obviously have to listen on earphones if you're going use voice. 73 de Brian/K3KO -- View this message in context: http://www.nabble.com/Monitoring-yourself-tp16918110p16925831.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Splicing mic cables
Hi Jim, The way I handle that wire is to strip it and fold it back on itself, then bind it with thin wire taken from some flexible cable, then if necessary lightly solder it, that always works for me. Paul G4LNA. Jim Wiley-2 wrote: I have a question that perhaps someone on this list might have the answer to. Does anyone know of good method for splicing tinsel-wire cables? I am trying to repair a microphone extension cable that got ripped in two. The cable in question is a 6-wire microphone cable, with conductors that look to be about 24 to 26 gauge in size. The conductors consist of copper foil wrapped around some sort of fabric core. Attempts at stripping were dismal, using several different techniques. The cable is normally terminated into a RJ type connector, that apparently uses ID (insulation displacement) to connect to the wires. I am considering something like Scotch UR type splices, but don't want to spend money on a box without knowing if they will work or not. A new cable is a possibility, but the existing one is built in to a console, and several hours of work would be involved in removing and replacing the existing cable. Soldering to individual conductors does not work. The resulting connection is weak and very fragile. - Jim, KL7CC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
