Excuse me while I learn what questions to ask, Wondering if there is a logging and more program that will allow use of CW and the PSK D and FSK D modes of my KX3 in a more complete application than the KX3 utility terminal?
Secondly...how do you tune in stations using PSK D and FSK D? I find it very difficuly especially with other psk and rtty stations nearby. I haven't gotten NAP3 or the KX3Companion to tune correctly as yet except for SSB and CW wher they do a fine job.
