If I remember correctly, there is a procedure in the K3 manual for manually setting the L and C values in the ATU. However, if all you're really interested in is getting the VSWR readings, then all you need do do is turn your power way down (2-3 W is enough), set the ATU to bypass (press and hold the ATU TUNE button), then press and hold the TUNE button. The VSWR will be displayed in the VFO-A display if my memory serves me correctly. This is outlined in the book as well but it may not be immediately obvious. Personally, I have set the TUN PWR to 2.5W in the config menu so I don't have to keep adjusting my power to do a quick antenna check. You might also try K3-EZ. It has a neat VSWR plotting routine.
I've seen 99:1 readings on very badly mismatched antennas and/or open connections which is one reason I keep my TUNE PWR set low. The default setting is "NOR" which uses whatever setting you have for transmit power... 73 And hope to catch you on the air Chuck - AA3CS Sent from my iPhone >> >> >> 1) Where can I find detailed instructions for using the KAT3?
