Bob,
To receive VLF you will need a VLF converter. The IF connection on the
K3 is only an output, so the converter will connect to one of the
antenna inputs to the K3. If it is to be receive only, you could
connect to the RX antenna input or to the ANT1 or ANT2 connections of
the KAT3, or to the RX port of the KXV3.
If the external device is to transmit as well as receive, you can
connect it to one of the KAT3 antenna jacks, or if it is capable of 1 mW
IF transmit levels, connect it to the same IF connectors as used for the
VHF/UHF transverters.

Howdy K3' people:
Here's another one I am trying to solve. What if I want to receive down
at 17.2KHz sometimes ... or certainly below 4 or 500KHz, the base of
the K3? Well,, that connection to the IF, was handy and safe, but now I
need external antenna.
Also, it is safest of when the SDR-IQ is not to the IF that we switch
the SDR-IQ input to maybe a 50 ohm dummy during xmit cycle of K3.
Anyone have this worked out? What equipment re you using and what
connection from K3 does the switching.
I have sequencer's for my 6m EME pre-amp ... just wondering what anyone
else does with the K3?
Actually, I need to know this anyway since the EME stuff was
driven/switched by my former rig, the FT-950 and I haven't figured out
how to switch the sequencer on K3 xmit anyway.
