K3: Upgrade of KAT3 possible?

Carey Magee
Hi. I have a couple of antennas I use that require no antenna tuner. I have
the KAT3 bypassed for those.

Is there an upgrade kit for the kat3, or do I need to buy the kat3a if I
want to take advantage of completely bypassing the tuner.

Many thanks.

73,
Carey

Hi Carey,

The KAT3A PC board required significant layout changes to add the bypass relay. It would be very difficult to modify a KAT3 for this purpose.

Carey,
You need to buy the KAT3A.
There is no upgrade kit for the KAT3. I would suspect the PC board layout to
be different for the KAT3A from the KAT3 to allow for the additional relay.
So I doubt there is any way to retrofit a KAT3 with the bypass relay.

Why not take two relays,put them in a box with connectors, and bypass the tuner externally.  We use relays as part of our switching system for two remote stations.

Send me an email direct and I will send you a schematic, part numbers and sources for the relays.
