Jim, As "advertized", in AFSK-A or FSK-D data submodes, the K3 should display the mark frequency. The K2 does not - it displays the suppressed carrier frequency. The K3 in DATA-A behaves the same as the K2 and displays the suppressed carrier frequency.
Check the data sub-mode that you have set on the K3 and also check the mark frequency you have set (HOLD PITCH). 73, Don W3FPR On 7/25/2011 6:47 PM, radioshoppe wrote: > Rich, Don and others who have responded, > > SRI it has taken several days to respond.
