Re: [Elecraft] K3 w/ straight key
Hi Jim, I don't know that you would have to turn off the keyer, per se. Just plug in the straight key to the "key" jack and leave your paddles plugged in to the "paddle" jack. Then, either would work. 73 Joe, N1QD On Wed, Jun 24, 2015 at 11:54 AM, Jim Hoge wrote: > I have always used my K3 with paddles but today wanted to play with a > straight key and a sideswiper.

[Elecraft] Building an older K2
Hello all, It's been years since I did any serious kit building, and I've been looking for a good winter project for a while now. So, when I found an unbuilt K2, KPA100, and KAT100-1 as part of an estate sale, I jumped on it. Are there any potential pitfalls I should be aware of, or is there anything I should be concerned about when assembling a 15-year old kit? All the boxes have 2002 purchase dates noted on them. The K2 is SN 3172, so I know it has the Rev "B" RF board. Thanks & 73, Joe Harris, N1QD __ 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] Another K3-SignaLink question
Ed, See page 20 of the K3 manual, in the Line Out setting. You can set the Line Out level in Config, or it can be set to =PHONES, which is what it sounds like you have it set to. 73, Joe, N1QD On Thu, Mar 27, 2014 at 3:09 PM, Edward F.

[Elecraft] Slight tx noise?
Hello, I have had a K3/100 for a few months and I'm loving it. My question concerns a barely audible, very high-pitched whine coming from the rig on transmit. Actually, it still happens when I'm in TX test mode. I don't believe it is the fans. I searched the reflector archives and didn't see anyone else mentioning it. Is this the norm, or am I blessed with a unique feature? 73, Joe, N1QD __ 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: KPA100 Squeal
I have very similar symptoms in my K3/100 (SN 5284) that I assembled in March. It makes the sound even if I am in TX test mode. Again, no performance issues, just a slightly bothersome squeal / whine.
