Interesting, the K3 also sounds distinctive on the air. N0SS, Tom is giving rides on the K3 and met me on 40m tonight with the K3. To me, the signal sounded very much like the sidetone you hear in the recording.
The DSP based Ten Tec Jupiters seem easy to pick out on the air, it's kind of a flutey note. The K3 is a little harder and sharper than that, but not as hard and sharp as analog signals. It sounds sweet and pure. I'm using a Corsair II with a cascaded 2.8 filter followed up by the Ten Tec 1.5khz filter (multiply by 1 to get the kc value). I'd like to do a Coke vs. Pepsi style comparison on K2 vs. K3 some day, I can pick the soda every time and bet it's at least as obvious comparing the two Elecraft rigs. Thanks so much to Tom for offering the sched, these guys will do anything including taking their rigs apart for us and then apologize on the air for delays. Not necessary of course. Great fun... [Elecraft] K3 - Sweet sidetone! Andrew Moore andrew.nv1b at gmail.com Thu Sep 20 21:54:21 EDT 2007 > Here is what the sidetone really sounds like (using the handy TX TEST feature of the K3 that disables output, but lets you oterwise "transmit"): http://www.kkn.net/~tree/160/Sidetone.mp3 It does sound good -- and different. It almost sounds like there's some kind of phase difference between right and left ears when using headphones. Is the K3 doing any kind of stereo processing to the sidetone signal to make it sounds so "good" (or different)? I had to admit, I didn't even copy the call sign in the .mp3 sample because I was so distracted by the different sounding sidetone. Not sure if that's a good thing. I'm just curious... is it a deliberate design decision or just some side effect of converting it to the .mp3 file or what? _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
