KAT3

[adamkern]

Listhost archives seem to be down at the moment, so apologies
if the following question has already been asked:

Can Wayne, Eric or anyone else comment more on the KAT3
design?  Specifically, how is the matching network configured,
is it "balanced" or "unbalanced" and is there any balun built-in?

Thanks,

Adam, N1KO

Hi Adam,

The KAT3 is a wide-range tuner based on an L-network with switchable
lo/hi Z. It tunes quickly, using our proven 3-stage firmware algorithm.
LC data is saved for many segments in each band, so you'll rarely need
to re-tune.

There are two antenna jacks, and the settings are saved for both
antennas on all bands. You select the antenna using the front panel ANT
switch. You can also assign names to each antenna (e.g., "YAGI",
"VERT2"). The name is briefly displayed when you change antennas or
bands as a reminder.

There's a separate connector for the KRX3 subreceiver, which can take
its input from the main receiver's RF path, or from the antenna jack
not being used by the main receiver.

Both antenna inputs are protected by gas-discharge tubes and bleeder
resistors. The jack that goes to the KRX3 is protected in addition by a
carrier-operated relay on the KRX3 module itself.

73,
Wayne

Unbalanced, uses SO239 coax connectors.  Think of it as being like the
KAT100 in capability, but inside the K3.

Can it be configured to be active for ANT A, inactive for ANT B?
