Re: [Elecraft] Side Tone Volume Control
I agee, and would also like the sidetone volume separately adjustable from the spot volume.

Re: [Elecraft] side tone level adjust
There is a CONFIG value that adjusts overall AF gain - its called AF GAIN and can be set to Lo or Hi - but this just affects the overall range of all af gain (and side tone I think), I found the default of Lo was to low and set mine to Hi. However, as someone else posted, to 'adjust' side tone etc, use the MON control. HOLD the cmp/pwr/mon knob (bottom right of the 4 to the left of the main VFO knob). When you do this, niether the CMP or PWR LED will be lit and the VFO B display will show MON nn, where nn is a numeric value representing the monitor volume level. Then turn to adjust the level. Just press any button or knob to go back to normal function of CMP/PWR (which you can switch between with a TAP of the knob) Finding items in the menus : Both menus show the options in alphabetical order, and remember the last menu you were on until you turn the power off. The MAIN menu always comes up on LCD BRT and the CONFIG menu on FW REVS 73 de M0XDF, K3 #174 -- What is the purpose of the giant sequoia tree?

Bruce, While in CW mode, hold the MON knob for 1 second. This will display the monitor or side tone level. Twist the knob to your desired setting and send away. I hope this helps.

RE: [Elecraft] Side Tone (Choosing the right "music") Mostly OT
So maybe Chinese or Indian export models should include more sidetone options. Hi. My offset is also around 600 hz. In a blind test, it sort of settled there, but I remember being undecided because the steps were too far apart. Like some other tone close by would actually have been better for me. Anyway, it is something that I have been kicking around with no background to make sense of it. Your note helps give me some direction for further research. A friend of mine has a PhD in Dance specializing in Balinese dance and she has mentioned the expanded scale of Eastern music as well. There is always a way to make a BFD out of the simplest thing...even a sidetone.

RE: [Elecraft] Side Tone
Charles, The parts for the sidetone waveshape mod are included with the KATOBKT from Elecraft. The values differ slightly from those in the original sidetone waveshape mod, but both work - still not a pure sinewave, but much closer than before. You should consider doing the complete A to B upgrade including all the optional parts along with making a change to the new crystal set - you will not be sorry after you hear the difference. Download the A to B instruction manual and look at the changes listed on the first page. And if you are considering the addition of a KPA100, I highly recommend that you also add the keying waveshape change. The Extremely Strong Signal Handling change came after the A to B kit too, but no kit for it - just takes 2 1N4148 diodes to add it. For about $70US you can end up with a K2 that is equal to the current production K2s - there IS a difference. 73, Don W3FPR > -Original Message- > > I built K2 Nr 413 and made lots of CW contacts, the built in Mojo > was great. > I stopped using it because the crystal oscillator in the side tone was > not a pure sine wave and it became offensive to my ear.

I stopped using it because the crystal oscillator in the side tone was not a pure sine wave and it became offensive to my ear. I only use CW. I have been informed by a K2 op that the more recent versions have a better side tone. That is correct, Charles. There was a mod by WJ4P, called the "Sinewave Sidetone Mod" which involved fitting a 47K resistor in series with C24 (0.0027uF) on the control board and soldering a 39mH choke across pins 7 & 10 of RP5. Ensure that C33 is a 2.2uF. If not, replace it. There is a document around about the mod somewhere and I am trying to locate it. If I find it I will e-mail it to you. The later Revision B K2 has a sinewave mod incorporated. 73 de David G4DMP ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
