There are four different data sub-modes on the K3 (selectable by holding the AFX/DATA MD button).
Do you have the same data sub-mode selected on all three bands? The default filter center frequency in DATA A is 1500 Hz, which is consistent with what you are reporting on 20m. The default center frequency in AFSK A is 2210 Hz if the Pitch is set to 2125 Hz, and that would seem to correspond with what you are seeing on 15m and 10m. It is also possible that your software is interfering, for example by forcing the filter frequency to a pre-defined setting depending on the mode and sub-mode. You can test this by configuring the software's radio control port to a non-existent port so that the software does not have CAT control, and then adjusting the radio's controls to see what happens. 73, Rich VE3KI IK1BXN wrote: > Sorry I forgot telling it happens in Data Mode. 73 de Giorgio ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
