Re: [Elecraft] CW transmitting - any clicks?
My K2 emits a very faint tick sound at the end of each dot and dash - I can hear it if I put my ear near the back of the K3. This happens using the internal keyer and a straight key, although it's extremely hard to hear using a straight key as the mechanical sound from the key itself masks it even when releasing it very gently. It's not coming from the speaker. Have other people noticed this? I wonder what is causing it? It does this even with the power level set to zero and I have VOX+QSK set. 73 de Graham G3ZOD FISTS #8385 http://www.fists.co.uk -Original Message- Steve, The K2, K1, KX1 and K3 all have electronic Transmit/Receive switching, and I would expect the KX3 will as well, so there will be no relay clicking noise. 73, Don W3FPR __ 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] CW transmit filter bandwith
Many thanks for the on and off-list replies. It would be useful if folk could write to W8JI and ask him to consider updating his article (his email is on QRZ.COM) to cover modern CW generation techniques, since it could result in folk like myself making bad decisions about choosing transmit filter bandwidths. I would do this but I think it needs people with a better understanding of the subject than I have (although it's improving, thanks!). Perhaps also the K3 firmware shouldn't allow selection of very narrow filters for CW transmission? 73 de Graham G3ZOD FISTS #8385 http://www.fists.co.uk -Original Message- Tom W8JI was dealing with analog transceivers when that was written. The K3 generates the signal digitally in the DSP portion of the transceiver, so many of those old rules of thumb for analog radios do not apply to the K3. As Guy has said many times on this reflector, This is not your grandaddy's analog radio. A properly operating K3 does not have key clicks and its transmit IMD is very good. 73, Don W3FPR On 1/17/2011 1:09 PM, Graham Smith wrote: I was reading W8JI's article http://www.w8ji.com/what_causes_clicks.htm but see that the advice in it (use a narrower filter than an SSB filter for transmitting CW) conflicts with the K3 manual, which says: Rotate VFO A to select a CW transmit filter (2.7 or 2.8 kHz). Note: Key clicks may result if a narrower filter is selected for CW transmit. Of course I will take the K3 manual's advice, but I am wondering why a narrow filter can cause key clicks? 73 de Graham G3ZOD FISTS #8385 http://www.fists.co.uk __ 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] Import to the UK
Simon, it's worth checking to see if it's less expensive to buy from QRPproject in Germany (Elecraft's European distributor). http://www.qrpproject.de/UK/indexuk.html Because it's in the Eu, the VAT is included in the price and you don't have to pay the incoming carrier VAT or a (large!!) handling fee for the privilege of taking the VAT off you. From their web page: No Custom declaration problems,VAT included, shipment only 8,00 Euro 73 de Graham G3ZOD FISTS #8385 http://www.fists.co.uk -Original Message- Date: Tue, 17 Aug 2010 17:24:28 +0100 From: Simon Faulkner si...@titanic.co.uk Subject: Re: [Elecraft] Import to the UK To: elecraft@mailman.qth.net Message-ID: 4c6ab7bc.60...@titanic.co.uk Content-Type: text/plain; charset=ISO-8859-1; format=flowed Thanks for the off list replies.

Re: [Elecraft] My question is, Do you folks think it is really necessary to , detail-inventory the Elecraft K2 product??
I prefer to do the inventory, although it is admittedly very tedious. When I got to the end of the K2 inventory, I was missing a choke - turns out that I had mis-identified one and there was in fact nothing missing. It's a lot easier sorting this out during the inventory than desoldering later, especially for items with more than two legs! 73 de Graham G3ZOD FISTS #8385 http://www.fists.co.uk __ 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] AFSK - K3 - SignaLink USB
That's not quite right; the SignaLink USB incorporates a USB sound card, freeing up any sound card(s) installed in the computer itself for other uses. 73 de Graham G3ZOD FISTS #8385 http://www.fists.co.uk -Original Message- Message: 24 Date: Wed, 30 Jun 2010 20:43:28 -0700 From: wb6r...@mac.com Subject: Re: [Elecraft] AFSK - K3 - SignaLink USB To: Elecraft Reflector elecraft@mailman.qth.net Message-ID: 3597f80a-718d-4f36-8d97-ca5c6daff...@mac.com Content-Type: text/plain; charset=us-ascii If you look at the schematic of the SignaLink, you'll see that it is redundant to what is already built into the K3. In addition, the K3 has a stereo audio out interface, facilitating the use of software for AFSK that recognizes dual RX for split frequency DX chasing. http://www.tigertronics.com/sl_mods.htm __ 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
