K3 with the AS-419 bandpass filter system

[NOEL POULIN]

I would like to know is anybody in this group using the AS-419
bandpassfilter system with the K3?
I was told it was possible to hook the system to the K3 for automatic
band change, without any band decoder??
Comments will welcome.
Thanks
NOel

Noel,

The data sheet says that it does, and I would believe it. The K3 puts
out band data in several forms on the AUX connector.  Have you looked in
the K3 manual?  It's detailed there, and you can download the manual for
the AS-419.  Have you done that? You'll need a suitably wired cable
between the AUX port and the AS-419.

Noel, the 419 has two "input modes" for selecting bands using the connector on the rear:

PBM = Per Band Mode, where 12V is put on an appropriate pin for the band you wish to select, that is, one of 6 pins.
BDM= Band Data Mode, where Band0 to Band3 data is applied to the connector, and the 419 does the decoding.

The pin outs for the connector for either mode are etched on the back of the 419.

To enter BDM, hold the mode button and push and release the 10m button.  If you look under the 10m button, you'll see a label "BDM".

To enter PBM, hold the mode button and push and release the 15m button.  If you look under the 15m button, you'll see a label "PBM".
