Hi Folks,
I'm having a go at my first CW contest for many years (and boy, am I rusty!!). I've worked several new countries already, BUT, I noticed my K3s main and sub receivers' 400Hz and 200Hz CW filter offsets are all quite a bit off (even though I put the offsets in that were written on the filters), causing me to tune the stations in at a lower than optimal tone (in order to hear them properly) and trying to put in an XIT offset so they can hear me in their tight RX passband. So far, it's not working that well. At a rough guess, I'd say they were about 200 to 300Hz low of where I need them to be (600Hz tone is my chosen optimal listening frequency). So, my question is, is there a simple way to accurately determine what the frequency offset of each filter is without having to open the rig up and dive in with test equipment? I'm guessing it could be something like: a. Tune in a strong-ish CW station or carrier to exactly 600Hz audio (use the tone mon to compare with the 600Hz reference audibly) b. Note the VFO frequency (on FINE) c. Use the RIT function to tune the station/carrier in to the peak of the crystal filter d. Note the offset e. Apply the offset to the crystal filter bank What do you think of this procedure? Got a better/quicker one? Any/all input most gratefully accepted.
