[KX3] VHF BNC mod kit recommended with 2m module?

For early model KX3, there is a mod kit for the BNC connector which added extra filtering to reduce weak signal interference on VHF/UHF. Is this mod recommended if the 2m transverter is installed in the KX3? Will it cause interference to itself on 2m without the mod?

This mod, which was phased into production long ago, only pertains to the HF-6 meter antenna jack (BNC). It has no impact on the 2-meter module, which uses the SMA jack.

Re: [KX3] VHF BNC mod kit recommended with 2m module?

Well, my KX3 is an early model that predates the point at which this mod was phased into production. I understand that the transverter module uses a separate SMA jack; my question is, while using the transverter, could there be leakage out the HF/6m antenna on the BNC jack that may be picked up by the 2m antenna on the SMA jack? Or is the BNC jack disconnected during transverter operation in a way that would prevent any such leakage?

Matt,
I have asked the same question to Eric at the HamRadio fair in
Friedrichshafen. From what I understood, you don't need the mod because
you can either operate on VHF or on HF. The mod makes sense if you have
another VHF radio which you like to operate in parallel to the KX3.
