Don, Please explain what you mean by "split tone". I do not understand that term without some clarification.
For RTTY, there are two tones, usually separated by 170 Hz, and CW is a single tone. The offset from the suppressed carrier frequency may be a consideration in determining the actual signal frequency, but that is usually not relevant. Different radios display the frequency differently, and that must be taken into consideration if you are doing CW using audio tones generated by the soundcard. for native CW. On the K3, the transmit frequency is displayed if you are in CW mode, and in SSB mode (or DATA A) the suppressed carrier frequency is displayed, so the CW keying method (audio or RS-232 keying) you are using is a consideration for use with HRD keying. It all depends on what you are doing. 73, Don W3FPR On 1/2/2011 10:36 PM, gold...@charter.net wrote: > Dear All, > > When operating CW or Rtty there is a split tone that you have to know > about.
