[Elecraft] [K3} Firmware version 4.12 with K144XV query

[Jeff Cochrane - VK4BOF]

Hi,
I was wondering, has anyone else played with firmware 4.12 on a K3 with the K144XV installed on 2M?
My local 2M repeater here in usually (on several other radios) S9+40db or more (AKA Full Scale) and on my K3 with firmware 4.05 it was S9+10db.
With firmware 4.12 it is now S4!

I have recently replaced a faulty K144XV unit in my radio so do I need to redo the RF Gain Calibration to suit it?

Any advice would be most welcome because at this stage of the game I am regretting my purchase of an Elecraft K3 and I'm getting pretty close to junking the whole damned radio it has gotten me that frustrated with it.
