[Elecraft] KX3 VFO leakage on antenna

[Walter Underwood]

The RX ISO preamp draws a bit more current than the regular preamp, so it defaults to off to preserve battery life. As far as I know, that is the only negative.

KX3 models after the mid-2000 serial numbers also have a filter on the BNC to knock down some leakage in the VHF range. Mine has it — the tiniest toroid I’ve ever seen. Details about that upgrade for older KX3’s are here:
