Re: [Elecraft] KX1 Filter Explanation for Dummies
Burke, You probably don't need to change the sidetone pitch. If you like the way it sounds when you're sending CW, then it's probably fine. Just remember to tune the received signal so it sounds like the sidetone pitch and you'll be OK when you crank the filter down to 1KHz or lower. Below about 500Hz you'll notice some issues and will probably want to use RIT, but you can leave that for a later day once you get the current issue under control. If you don't like the sidetone, tap the KX1 menu button and rotate the VFO knob until it says StP. Press and hold the menu button and it will show the current sidetone pitch. Rotate the VFO knob and listen to the pitch you like; 600 Hz is a good starting point. Then tap the Menu button to exit.

I might need to revist the manual and the part about setting the sidetone frequency. I can't remember what I did. Thanks!

When you set the sidetone frequency in the KX1 menus, you are also choosing the offset at which you hear received signals. So if you set it to 600 Hz, you'll be right on frequency with the other station when the signal you hear is a 600 Hz tone. You can match this tone by ear by goign back to the menu to StP or StL (better since it doesn't accidently change StP) and listening for the same pitch, within about 10 Hz. Once you get on the same frequency, turning the filter down to about 1 Khz will cut out most of the QRM and QRN and will give you a pleasant listening experience. If you're off frequency, the received signal will fall outside the filter passband and you'll be treating it as you would a QRM or off-frequency station, and it will be attentuated. 2. If you turn the filter below 1 Khz, and more prominently, below 500 Hz, the center frequency of the filter itself shifts down a bit, so you may need to re-tune slightly to get the signal back to full strength. Unfortunately, if you do this, you'll also be shifting your transmit frequency, so you can use the RIT feature of the KX1 just to shift the received frequency and leave your transmit frequency alone. You probably won't need to do this unless you need to crank the filter way down, as in a contest, or with a very noisy band. So you can safely ignore this for now and use the filter at about 1 Khz until you feel the need to learn more. Does this answer your question, or do you have a different issue that I've misunderstood? Leigh/WA5ZNU KX1 #712 Okay, so now that I am actually using my KX-1, I need some help. I am really a newbie when it comes to this stuff. Can someone please give me an explanation (at a basic level) of how you are actually supposed to use the filter on the KX-1? If I am listening to a signal, and then turn the filter, I seem to lose the signal. Is this because I am not tuned exactly to that signal? Thanks for being patient, someday it will all make sense.
