K3 FSK Passband Frequency

[Bud Governale, W3LL]

I'm using FSK-D.
To tune in an FSK signal I need to use Shift to shift the signal to the right of the passband display on the K3
(centered over the right side arrow). This then places the signal in the center of the MTTY display. However, received
signals are now about 0.55 KHz higher than spotted reports. If I click on a spot I have to search for the signal.
Normalizing the K3 passband puts the signals completely out of the receive passband and nothing is heard or seen in the
MTTY display.
Is this normal or am I doing something wrong?

Use the K3 PITCH to set the RTTY tones to match the selected MTTY tone
pitch (or vice-versa).

Hi Bud:

If you make sure that the MMTTY Mark freq is set to the same pitch as
the Mark freq on the K3, I'm sure you will find that the RTTY signal
will appear in the center of the MMTTY screen with the K3 passband centered.

Hi Bud,
I use FSK. The pitch on the K3 is set to match what I have set up in AXETTY
or MMTTY - 2125/170. I do not have an offset doing it this way. Since I am
using FSK I also do not have the AFC ON in the RTTY program.
The dual passband humps are centered between the two arrows.

73,
N2TK, Tony
