Re: [Elecraft] K3-PSK/RTTY Question
Hi Bill, Good deal on the order in! As soon as they get past midnight then you should be close. I have a whole handful of small transformers both from digikey and radio shack we got for club interface project. And bunches of optical coupled Darlingtons. And perfboard I used in the past. Also have a breadboard that just has three transformers ( for dual receive) with pairs of RCA connectors. I first just connected the cables directly to my laptop but the hum/noise was not acceptable. Even pulled the AC cord on the laptop and ran on batteries. But then I expected that based on early interfaces for my other pre-K3 radios. and back to the start of this thread. yes, the SignaLin-USB should be fine also. Especially if you happen to have one handy. 73, tom n4zpt On 5/3/2012 3:35 PM, Bill Conkling wrote: > Welll > > My KX3 is on the list, I'm near the top of Dec 28 (00:23:59) so I am not > sure at this point.

Re: [Elecraft] K3-PSK/RTTY Question
Welll My KX3 is on the list, I'm near the top of Dec 28 (00:23:59) so I am not sure at this point. I have a circuit board that has holes for a couple of iso transformers, and a pot. Will prob put something together using it when it gets here.

Re: [Elecraft] K3-PSK/RTTY Question
Hi Bill, For my K3 I do just as you say. A serial cable plus two audio cables connected to the line in/out of my computer sound card and my K3. Tossed my homebrew interface I used with my FT-1000 in the parts box. However my laptop does not have line in/out and so far the KX3 does not have line in/out. I get odd noise that looks like hum plus some scruff when I connect my KX3 directly to my laptop. It works but do not want to transmit the noise. So some sort of isolation and level adjusting is needed beyond just the computer sliders and KX3 mike gain and speaker level adjustment. Seems to me that is. So for my KX3 I just picked up the TRRS and TRS right angle connectors and plan to hook up one of my unterminated SL-USB cables ( short Ethernet cut in half) to play. Given the SL-USB is in my go kit anyway with my laptop. May use one of the inexpensive interface boards I found on eBay with a couple transformers and transistor switch. Or just grab some resistors and audio isolation transformers out of my parts boxes, i.e. dust off my old interface board. So yes, with the KX3 seems an interface is needed.

Re: [Elecraft] K3-PSK/RTTY Question
Hi, Steve, \ I really think the SL-USB is a real nice interface if you need an interface. But in my opinion, for the K3/KX3 it is over-kill. I use two stereo audio cables between the sound card and the K3 and it works just fine. The K3 is already buffered and isolated with transformers (KX3 will not be). Unless you need the sound card for computer sounds and/or other audio uses, I'd just use the computer sound card. PTT can be handled via the serial CAT cable. bill nr4c On Thu, 03 May 2012 07:32:45 -0400, Steve wrote: > Good Morning All, > I have a K3 and am awaiting my KX3soon I hope... > My question is that I am wanting to put the K3 on > PSK and RTTY and I'm wondering if > my choice of the Signalink USP is a good choice > for these modes with the K3 and hopefully the KX3 > Tnx es VY73' > Steve W8CRH > SEMPER FI > __ > 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 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-PSK/RTTY Question
Steve... Although some argue that adjuncts like the SignaLink are not needed. I have used SignaLinks on a K2, an ICOM 910H, and now my K3/100+P3. I am very pleased with the way in which it gives me that extra little degree of control, and in particular in the way in which it enhances FLDIGI/FLRIG for both RTTYand PSK of all speeds. For $67 it has been worth every nickel of the price, especially vis-a-vis the costs of the other parts of my HF station. I run FLDIGI/FLRIG and the screen-captured P3 screen on one of my two monitors, which leaves the other one free for any other need. On the various PSK speeds, I run at 25 watts on the K3, and on RTTY I move the output up to 75-80 watts. If I want to run CW, I just shut down FLDIGI (it is not a sterling performer on CW) and run without a decoder. Even on my forays into SSB (usually on VHF or UHF, where I run >350 watts) I leave FLRIG running, as it gives very nice semi-remote access to many of the K3 parameters, but that has little to do with the "issue" of using a SignaLink.
