Like on most of our radios, the KAT4 ATU is optional and can be added at any time. This allows those using the K4 full time via an external amp with ATU and external antenna switching to lower their cost.  This also applies to those who are dedicating a K4 as an IF radio for VHF/UHF/Microwave.


 > 2- how many USB ports on front panel?

The K4 has one USB-A on the front, two USB-A on the rear.  If more inputs are
needed, an external USB hub can be used on any of these.
Mouse, Keyboard, Flash Drive etc can be plugged into these ports.

The K4 also has  one USB-B on the rear (with internal sound card and mutiple
comm ports like the K3S).
>>> 3- how many SO-239 connectors on rear of K4?  Photo shows 4 but I wonder if that’s the rear of a K4 or K4D?
All three K4 versions start with one SO-239 for Hf-6M.  Three total when the
KAT4 is added.
There is a 4th rear position for an antenna connector when a future planned
VHF/UHF dual-band internal module is released later next year. That will
accommodate a SO-239 or type N socket.
>>> 4- is there I/Q output for either or both VFOs?
Yes, over Ethernet.
>>> 5- if I plop down $1500 on a K4 today, can I send the other $2500 prior to start of shipping and get moved to the 1st shipping group? Or is that a limited time offer?
As long as we have not filled it up, we'll move you up to the 1st shipping
group.  We'll post when the first group is full, which will happen soon.

Re: Fwd: K4 Questions

Hello Eric,
    Just to be sure, I hope there are two separate RX antenna inputs for
diversity reception on the K4D.    Is this true are the RX ANT connectors
type BNC?

    Will one need to take the K4D completely apart if later a decision is
made to add the two superhet front ends?

    Thank you for all the good product, excellent service and presence of
the engineering team on the forum.
         73 Doug EI2CN

Hello Eric,
     Sorry I now have a good view of the rear panel so know there are two
separate type BNC connectors for RX antennas used in Duplex.    

     I would still like to know how much disassembly is required to install
the two superhet front ends.  

     Thank you.

*Yes. Each RX in the K4D, or HD, can receive via the two rear BNCs, plus any of
the three SO-239's if the KAT4 is installed.*

*Remove top cover and plug in Dual superhet pcb. No complex disassembly. **

Hi Eric,

Is the sampling clock for the internal sound card driven by the
reference oscillator? Or does it have an independent crystal oscillator
for sampling?

Thanks and 73, tom w7sua

'Sound card' clocks are usually independent of others in the system.
